"Heavy heart": Susie O'Neill breaks down as she resigns live on air

<p>Olympic swimmer turned radio host Susie O'Neill has broken down live on air as she announced her resignation from her role with the Brisbane Nova breakfast show.</p> <p>The 51-year-old tearfully told her co-hosts David 'Luttsy' Lutteral and Ashley Bradnam that she would be taking a step back from radio after 10 years with the network. </p> <p>"I do this with a heavy heart, the decision wasn't easy. It's hard for me to articulate exactly why I'm leaving," Susie began.</p> <p>"Turning 50 last year, I realised I'm at a whole new stage in my life. The next chapter will see me pursue other goals, both professionally and personally."</p> <p>Susie added that she was already contemplating what her next career moves would be, as she reassured listeners that she would stay on the air for another six weeks, with her final show being on November 28th.</p> <p>"I want to get back to the grassroots of sport and involve myself in the wider community. It's going to be an emotional final day, saying goodbye to everyone," she said.</p> <p>"Whatever this next chapter brings, my Nova family won't be far away."</p> <p>She went on to thank both of her co-hosts a she reflected on her time on the show, saying, "Thanks to Ash and Luttsy for bringing me into your world and life a bit over 10 years ago now, when I pretty much had nothing going on in my life to be honest."</p> <p>"I joked that it saved my life at the time. You were both so supportive of me. I was horrible at radio and I’d be upset and say, 'I can’t do it' and you would say, 'no, just keep going, just keep going'."</p> <p>Co-host Luttsy was quick to pay tribute to Susie, saying, "It's been an incredible adventure becoming great mates with you. Can't wait to see your next chapter."</p> <p>Before joining the world of radio in 2023 as a sports broadcaster, Susie rose to fame at the age of just 14, joining the Olympic team and going on to score 35 Australian titles and retiring after the 2000 Sydney Olympics. </p> <p><em>Image credits: Nova</em></p>

Channel 7 star hospitalised over heart issue

<p>Former Brisbane Lions AFLW star Kate McCarthy’s celebrations following the Brisbane Lions men’s AFL grand final victory were cut short after she was hospitalised due to an ongoing heart condition.</p> <p>McCarthy, 31, who played 42 games in the AFLW for the Brisbane Lions, St Kilda and Hawthorn across seven seasons before retiring, has been an active presence in the world of AFL even after stepping off the field. She currently serves as a commentator for Triple M and Channel 7, having provided coverage for Channel 7 during the AFL grand final weekend. McCarthy also co-hosts panel shows <em>Armchair Experts</em> and <em>Talking W</em>.</p> <p>Over the weekend, McCarthy celebrated the Lions’ dominant 60-point grand final win over the Sydney Swans and their AFLW team’s two-point victory over the Adelaide Crows, which pushed the women’s team to second place on the ladder.</p> <p>However, McCarthy took to social media platform X (formerly Twitter) on Tuesday to reveal she had been hospitalised due to a heart-related issue, sharing a light-hearted post about the situation: “When the @brisbanelions & @lionsaflw double over the weekend sends you into ventricular tachycardia."</p> <p>Ventricular tachycardia is a condition where the heart beats faster than 100 beats per minute, causing a rapid and irregular rhythm. This can become life-threatening if left untreated, especially for individuals with underlying heart conditions.</p> <p>McCarthy’s heart issues are particularly dangerous due to her reliance on a pacemaker, which was implanted after she suffered from seizures as a child. At the age of five, McCarthy was diagnosed with an intermittent third-degree heart block, a condition where the electrical signals that control the heart’s rhythm fail to fire properly. After several seizures during her childhood, including a severe episode when she was 12, she underwent emergency surgery to install the pacemaker.</p> <p>Despite these health challenges, McCarthy’s sporting career has been nothing short of remarkable. She represented Queensland in cricket and touch footy and played for Australia in the latter before making her AFLW debut for the Lions in 2017. Her AFLW career highlights include being named an All-Australian and the Lions’ leading goal kicker in their inaugural season.</p> <p>McCarthy’s heart condition appears to be under control, with her pacemaker functioning as intended. While her health scare has been concerning, she reassured her followers that she is on the mend, humorously comparing her pacemaker’s performance to that of the Sydney Swans on grand final day.</p> <p>"On the mend now," McCarthy wrote, "but Monday night review shows pacemaker performing like the Swans on the big stage.”</p> <p><em>Images: Twitter (X)</em></p>

What’s the difference between a heart attack and cardiac arrest? One’s about plumbing, the other wiring

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/michael-todorovic-1210507">Michael Todorovic</a>, <a href="https://theconversation.com/institutions/bond-university-863">Bond University</a> and <a href="https://theconversation.com/profiles/matthew-barton-1184088">Matthew Barton</a>, <a href="https://theconversation.com/institutions/griffith-university-828">Griffith University</a></em></p> <p>In July 2023, rising US basketball star Bronny James collapsed on the court during practice and was sent to hospital. The 18-year-old athlete, son of famous LA Lakers’ veteran LeBron James, had experienced a <a href="https://apnews.com/article/bronny-james-cardiac-arrest-3953eee8789e83f3cccfb6dd798bc54e">cardiac arrest</a>.</p> <p>Many media outlets incorrectly referred to the event as a “<a href="https://en.as.com/nba/lebron-james-son-bronny-plays-for-the-usc-trojans-for-the-first-time-since-suffering-a-heart-attack-n/">heart attack</a>” or used the terms interchangeably.</p> <p>A cardiac arrest and a heart attack are distinct yet overlapping concepts associated with the heart.</p> <p>With some background in <a href="https://www.youtube.com/watch?v=uKrgEv7-rVM&amp;t=16s">how the heart works</a>, we can see how they differ and how they’re related.</p> <h2>Understanding the heart</h2> <p>The heart is a muscle that contracts to work as a pump. When it contracts it pushes blood – containing oxygen and nutrients – to all the tissues of our body.</p> <p>For the heart muscle to work effectively as a pump, it needs to be fed its own blood supply, delivered by the coronary arteries. If these arteries are blocked, the heart muscle doesn’t get the blood it needs.</p> <p>This can cause the heart muscle to become injured or die, and results in the heart not pumping properly.</p> <h2>Heart attack or cardiac arrest?</h2> <p>Simply put, a heart attack, technically known as a myocardial infarction, describes injury to, or death of, the heart muscle.</p> <p>A cardiac arrest, sometimes called a sudden cardiac arrest, is when the heart stops beating, or put another way, stops working as an effective pump.</p> <p>In other words, both relate to the heart not working as it should, but for different reasons. As we’ll see later, one can lead to the other.</p> <h2>Why do they happen? Who’s at risk?</h2> <p>Heart attacks typically result from blockages in the coronary arteries. Sometimes this is called coronary artery disease, but in Australia, we tend to refer to it as ischaemic heart disease.</p> <p>The underlying cause in about <a href="https://www.ncbi.nlm.nih.gov/books/NBK507799/#:%7E:text=It%20has%20been%20reported%20that,increases%20beyond%20age%2050%20years.">75% of people</a> is a process called <a href="https://youtu.be/jwL4lkSlvSA?si=H2as7dQkhbIqWWkU">atherosclerosis</a>. This is where fatty and fibrous tissue build up in the walls of the coronary arteries, forming a plaque. The plaque can block the blood vessel or, in some instances, lead to the formation of a blood clot.</p> <p>Atherosclerosis is a long-term, stealthy process, with a number of risk factors that can sneak up on anyone. High blood pressure, high cholesterol, diet, diabetes, stress, and your genes have all been implicated in this plaque-building process.</p> <p>Other causes of heart attacks include spasms of the coronary arteries (causing them to constrict), chest trauma, or anything else that reduces blood flow to the heart muscle.</p> <p>Regardless of the cause, blocking or reducing the flow of blood through these pipes can result in the heart muscle not receiving enough oxygen and nutrients. So cells in the heart muscle can be injured or die.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/597616/original/file-20240531-17-o2j0w.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/597616/original/file-20240531-17-o2j0w.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/597616/original/file-20240531-17-o2j0w.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=338&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/597616/original/file-20240531-17-o2j0w.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=338&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/597616/original/file-20240531-17-o2j0w.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=338&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/597616/original/file-20240531-17-o2j0w.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=424&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/597616/original/file-20240531-17-o2j0w.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=424&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/597616/original/file-20240531-17-o2j0w.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=424&amp;fit=crop&amp;dpr=3 2262w" alt="Heart attack vs cardiac arrest" /></a><figcaption><span class="caption">Here’s a simple way to remember the difference.</span> <span class="attribution"><span class="source">Author provided</span></span></figcaption></figure> <p>But a cardiac arrest is the result of heartbeat irregularities, making it harder for the heart to pump blood effectively around the body. These heartbeat irregularities are generally due to <a href="https://www.youtube.com/watch?v=M_soKG-Tzh0&amp;t=903s">electrical malfunctions</a> in the heart. There are four distinct types:</p> <ul> <li> <p><strong>ventricular tachycardia:</strong> a rapid and abnormal heart rhythm in which the heartbeat is more than <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10541285/">100 beats per minute</a> (normal adult, resting heart rate is generally 60-90 beats per minute). This fast heart rate prevents the heart from filling with blood and thus pumping adequately</p> </li> <li> <p><strong>ventricular fibrillation:</strong> instead of regular beats, the heart quivers or “fibrillates”, resembling a bag of worms, resulting in an irregular heartbeat greater than 300 beats per minute</p> </li> <li> <p><strong>pulseless electrical activity:</strong> arises when the heart muscle fails to generate sufficient pumping force after electrical stimulation, resulting in no pulse</p> </li> <li> <p><strong>asystole:</strong> the classic flat-line heart rhythm you see in movies, indicating no electrical activity in the heart.</p> </li> </ul> <p>Cardiac arrest can arise from numerous underlying conditions, both heart-related and not, such as drowning, trauma, asphyxia, electrical shock and drug overdose. James’ cardiac arrest was attributed to a <a href="https://www.espn.com.au/mens-college-basketball/story/_/id/38260006/bronny-james-cardiac-arrest-caused-congenital-heart-defect">congenital heart defect</a>, a heart condition he was born with.</p> <p>But among the many causes of a cardiac arrest, ischaemic heart disease, such as a heart attack, stands out as the most common cause, accounting <a href="https://pubmed.ncbi.nlm.nih.gov/11898927/">for 70%</a> of all cases.</p> <p>So how can a heart attack cause a cardiac arrest? You’ll remember that during a heart attack, heart muscle can be damaged or parts of it may die. This damaged or dead tissue can disrupt the heart’s ability to conduct electrical signals, increasing the risk of developing arrhythmias, possibly causing a cardiac arrest.</p> <p>So while a heart attack is a common cause of cardiac arrest, a cardiac arrest generally does not cause a heart attack.</p> <h2>What do they look like?</h2> <p>Because a cardiac arrest results in the sudden loss of effective heart pumping, the most common signs and symptoms are a sudden loss of consciousness, absence of pulse or heartbeat, stopping of breathing, and pale or blue-tinged skin.</p> <p>But the common signs and symptoms of a heart attack include chest pain or discomfort, which can show up in other regions of the body such as the arms, back, neck, jaw, or stomach. Also frequent are shortness of breath, nausea, light-headedness, looking pale, and sweating.</p> <h2>What’s the take-home message?</h2> <p>While both heart attack and cardiac arrest are disorders related to the heart, they differ in their mechanisms and outcomes.</p> <p>A heart attack is like a blockage in the plumbing supplying water to a house. But a cardiac arrest is like an electrical malfunction in the house’s wiring.</p> <p>Despite their different nature both conditions can have severe consequences and require immediate medical attention.<!-- Below is The Conversation's page counter tag.

Constipation increases your risk of a heart attack, new study finds – and not just on the toilet

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/vincent-ho-141549">Vincent Ho</a>, <a href="https://theconversation.com/institutions/western-sydney-university-1092">Western Sydney University</a></em></p> <p>If you Google the terms “constipation” and “heart attack” it’s not long before the name Elvis Presley crops up. Elvis had a longstanding history of chronic constipation and <a href="https://www.pbs.org/newshour/health/elvis-addiction-was-the-perfect-prescription-for-an-early-death">it’s believed</a> he was straining very hard to poo, which then led to a fatal heart attack.</p> <p>We don’t know what really happened to the so-called King of Rock “n” Roll back in 1977. There were likely several contributing factors to his death, and this theory is one of many.</p> <p>But after this famous case researchers took a strong interest in the link between constipation and the risk of a heart attack.</p> <p>This includes a recent <a href="https://journals.physiology.org/doi/abs/10.1152/ajpheart.00519.2024">study</a> led by Australian researchers involving data from thousands of people.</p> <h2>Are constipation and heart attacks linked?</h2> <p>Large <a href="https://www.nature.com/articles/s41598-023-38068-y">population</a> <a href="https://pubmed.ncbi.nlm.nih.gov/32873621/">studies</a> show constipation is linked to an increased risk of heart attacks.</p> <p>For example, an <a href="https://www.nature.com/articles/s41598-023-38068-y">Australian study</a> involved more than 540,000 people over 60 in hospital for a range of conditions. It found constipated patients had a higher risk of high blood pressure, heart attacks and strokes compared to non-constipated patients of the same age.</p> <p>A <a href="https://pubmed.ncbi.nlm.nih.gov/32873621/">Danish study</a> of more than 900,000 people from hospitals and hospital outpatient clinics also found that people who were constipated had an increased risk of heart attacks and strokes.</p> <p>It was unclear, however, if this relationship between constipation and an increased risk of heart attacks and strokes would hold true for healthy people outside hospital.</p> <p>These Australian and Danish studies also did not factor in the effects of drugs used to treat high blood pressure (hypertension), which can make you constipated.</p> <h2>How about this new study?</h2> <p>The recent <a href="https://journals.physiology.org/doi/abs/10.1152/ajpheart.00519.2024">international study</a> led by Monash University researchers found a connection between constipation and an increased risk of heart attacks, strokes and heart failure in a general population.</p> <p>The researchers analysed data from the <a href="https://www.ukbiobank.ac.uk">UK Biobank</a>, a database of health-related information from about half a million people in the United Kingdom.</p> <p>The researchers identified more than 23,000 cases of constipation and accounted for the effect of drugs to treat high blood pressure, which can lead to constipation.</p> <p>People with constipation (identified through medical records or via a questionnaire) were twice as likely to have a heart attack, stroke or heart failure as those without constipation.</p> <p>The researchers found a strong link between high blood pressure and constipation. Individuals with hypertension who were also constipated had a 34% increased risk of a major heart event compared to those with just hypertension.</p> <p>The study only looked at the data from people of European ancestry. However, there is good reason to believe the link between constipation and heart attacks applies to other populations.</p> <p>A <a href="https://pubmed.ncbi.nlm.nih.gov/26812003/">Japanese study</a> looked at more than 45,000 men and women in the general population. It found people passing a bowel motion once every two to three days had a higher risk of dying from heart disease compared with ones who passed at least one bowel motion a day.</p> <h2>How might constipation cause a heart attack?</h2> <p>Chronic constipation can lead to straining when passing a stool. This can result in <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8030287/">laboured breathing</a> and can lead to a rise in blood pressure.</p> <p>In <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8030287/">one Japanese study</a> including ten elderly people, blood pressure was high just before passing a bowel motion and continued to rise during the bowel motion. This increase in blood pressure lasted for an hour afterwards, a pattern not seen in younger Japanese people.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8030287/">One theory</a> is that older people have stiffer blood vessels due to atherosclerosis (thickening or hardening of the arteries caused by a build-up of plaque) and other age-related changes. So their high blood pressure can persist for some time after straining. But the blood pressure of younger people returns quickly to normal as they have more elastic blood vessels.</p> <p>As blood pressure rises, the risk of heart disease increases. The risk of developing heart disease <a href="https://pubmed.ncbi.nlm.nih.gov/12493255/">doubles</a> when systolic blood pressure (the top number in your blood pressure reading) rises permanently by 20 mmHg (millimetres of mercury, a standard measure of blood pressure).</p> <p>The systolic blood pressure rise with straining in passing a stool has been <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8030287/">reported to be</a> as high as 70 mmHg. This rise is only temporary but with persistent straining in chronic constipation this could lead to an increased risk of heart attacks.</p> <p><a href="https://pubmed.ncbi.nlm.nih.gov/22256893/">Some people</a> with chronic constipation may have an impaired function of their vagus nerve, which controls various bodily functions, including digestion, heart rate and breathing.</p> <p>This impaired function can result in abnormalities of heart rate and over-activation of the flight-fight response. This can, in turn, lead to elevated blood pressure.</p> <p>Another intriguing avenue of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6399019/">research</a> examines the imbalance in gut bacteria in people with <a href="https://pubmed.ncbi.nlm.nih.gov/3596341/">constipation</a>.</p> <p>This imbalance, known as dysbiosis, can result in microbes and other substances leaking through the gut barrier into the bloodstream and triggering an immune response. This, in turn, can lead to low-grade inflammation in the blood circulation and arteries becoming stiffer, increasing the risk of a heart attack.</p> <p>This latest study also explored genetic links between constipation and heart disease. The researchers found shared genetic factors that underlie both constipation and heart disease.</p> <h2>What can we do about this?</h2> <p>Constipation affects around <a href="https://pubmed.ncbi.nlm.nih.gov/36826591/">19% of the global population</a> aged 60 and older. So there is a substantial portion of the population at an increased risk of heart disease due to their bowel health.</p> <p>Managing chronic constipation through dietary changes (particularly increased dietary fibre), increased physical activity, ensuring adequate hydration and using medications, if necessary, are all important ways to help improve bowel function and reduce the risk of heart disease.<!-- Below is The Conversation's page counter tag.

"My heart is broken": Mariah Carey reveals sad double tragedy

<p>Mariah Carey has revealed a devastating double tragedy, as both her mother and sister passed away on the same day. </p> <p>In a heartbreaking statement to <em><a href="https://people.com/mariah-carey-mom-patricia-sister-alison-both-died-same-day-exclusive-8701561" target="_blank" rel="noopener">People</a></em>, the singer announced the deaths of her mum Patricia, 87, and sister Alison, 63, who died over the weekend. </p> <p>Carey's statement read, "My heart is broken that I've lost my mother this past weekend. Sadly, in a tragic turn of events, my sister lost her life on the same day."</p> <p>"I feel blessed that I was able to spend the last week with my mom before she passed."</p> <p>"I appreciate everyone's love and support and respect for my privacy during this impossible time."</p> <p>No cause of death has been revealed for either member of the family. </p> <p>Carey famously had a turbulent relationship with her mother and sister over the years, and was estranged from Alison for three decades before her untimely death.</p> <p>In 2016, Alison, who was a recovering drug addict, made a plea to her famous sister through the Daily Mail to ask for support, saying, "Mariah I love you, I desperately need your help."</p> <p>As well as substance abuse, Alison endured homelessness throughout her life and tested positive for the HIV virus. </p> <p>Mariah opened up about complicated relationships with her mom and sister in her 2020 memoir, <em>The Meaning Of Mariah Carey</em>.</p> <p>"Like many aspects of my life, my journey with my mother has been full of contradictions and competing realities. It's never been only black-and-white — it's been a whole rainbow of emotions," she explained. </p> <p>She said their relationship was a "prickly rope of pride, pain, shame, gratitude, jealousy, admiration, and disappointment", however the book was still dedicated to Patricia.</p> <p>"And to Pat, my mother, who, through it all, I do believe actually did the best she could," the singer penned in the dedication. "I will love you the best I can, always."</p> <p><em>Image credits: Paul Archuleta/Shutterstock Editorial </em></p>

For example, walking, running, cycling, swimming and rowing.</p> <p>Muscles that are contracting during aerobic exercise use a lot of energy and need ten times <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4551211/">more oxygen than at rest</a>.</p> <p>High intensity aerobic events that involve large muscles or the entire body cause the highest heart rates.</p> <p>An <a href="https://www.heartonline.org.au/resources/calculators/target-heart-rate-calculator">estimate</a> of maximum heart rate (beats per minute) is 220 minus your age. This equates to 195 beats per minute for a 25-year-old – close to the average age of the Australian Olympic team of 26.5 years.</p> <p>Athletes competing in Olympic events of endurance or speed will reach their maximum heart rate.</p> <p>You can usually only maintain maximum heart rate for a few minutes. But in a 2000-metre rowing race, the rowers maintain intense effort at close to maximum heart rate for 6–8 minutes.</p> <p>This is one of the toughest events for the heart. It’s no wonder rowers often collapse in the boat <a href="https://www.bbc.com/news/uk-england-cambridgeshire-68731840">as they cross the finish line</a>.</p> <p>Highly trained endurance athletes can have a maximum heart rate higher than expected for their age. <a href="https://olympics.com/en/athletes/eliud-kipchoge">Eliud Kipchoge</a> from Kenya is considered the greatest marathon runner of all time. During his <a href="https://au.coros.com/stories?world-record">world record run</a> in the 2022 Berlin marathon, he ran with a heart rate of around 180 beats per minute for almost the entire race.</p> <h2>How does breathing change with exercise?</h2> <p>Our breathing changes with exercise to increase oxygen uptake from the air.</p> <p>At low-to-moderate intensity exercise, you start to take deeper breaths. This brings in more air and oxygen with each breath. However, there is a limit to how much the chest can expand.</p> <p>With higher intensity exercise, respiratory rate increases to increase oxygen intake.</p> <p>Elite athletes can breathe <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4818249/">more than 50 times</a> per minute.

92-year-old grandma steals hearts in Paris

<p>Australian judo champion Aoife Coughlan stunned Olympic audiences with a tense showdown against German athlete Miriam Butkereit in Paris, but some audience members had their attention drawn elsewhere. </p> <p>The 28-year-old Aussie was holding her own against Butkereit, until sudden-death overtime saw Butkereit, 30, win at the last second in the women's 70kg judo round of 16.</p> <p>Despite the unbelievable scenes inside Grand Palais Éphémère in Champ de Mars in Paris, some spectators were quick to notice a special guest hovering behind the TV cameras, who has since drawn the world's attention. </p> <p>Coughlan's 92-year-old grandmother Pam Coughlan, from Ireland, scored a prime position mat-side to watch her granddaughter compete, with the judoka's cousin explaining just how his grandmother secured her prime, and unusual, spot on social media.</p> <blockquote class="twitter-tweet"> <p dir="ltr" lang="en">My 92 year old granny is at the Olympics today to watch her Australian grandchild in the Judo.</p> <p>She persuaded them to let her sit here.

Mysterious leg pain that’s quietly killing older Australians

<p>Peripheral Artery Disease (PAD) has long been overshadowed by its more widely recognised counterparts, such as heart attacks and strokes. Often referred to as the “poor cousin” or “Cinderella” of cardiovascular diseases, PAD affects one in five older Australians, yet it remains largely under-diagnosed and misunderstood. However, a wave of optimism is sweeping through the medical community with the launch of <a href="https://www.hri.org.au/our-research/centreforpad" target="_blank" rel="noopener">The Centre for Peripheral Artery Disease</a>, an Australian-first facility dedicated to pioneering research and improving patient outcomes.</p> <p>Spearheaded by the Heart Research Institute, the Centre for Peripheral Artery Disease, marks a significant step forward in addressing the challenges posed by PAD. The centre aims to fill critical gaps in our understanding of the disease, which is responsible for a limb amputation in Australia every two hours. This initiative promises to enhance diagnosis, transform patient care, and raise awareness about PAD.</p> <p>Associate Professor Mary Kavurma, the Centre Lead, is at the forefront of this ground-breaking effort. “We’re supercharging research into PAD because there are still many unknowns about the disease’s biology that could unlock new methods for early detection and better management,” she explains. This research is particularly urgent given the prevalence of PAD among women and First Nations Australians, groups that remain disproportionately affected by this condition.</p> <p>The centre’s mission is to develop a simple blood test for early diagnosis and explore novel therapies that could reduce the need for limb amputations and significantly improve patients’ quality of life. Unlike current treatments that primarily focus on symptom management, this new approach seeks to prevent the disease from progressing.</p> <p>One of the most inspiring aspects of the centre is its commitment to involving patients and their families in the research process. At the inaugural consumer meeting, nearly 20 patients and their carers shared their personal experiences with PAD. </p> <p>Take the story of Simon Josephson, a renowned advertising guru – who famously designed the Solo logo. PAD almost cost him his life after taking more than five years to diagnose.</p> <p>He woke up one morning with a sore leg, thinking he’d overdone it exercising but the 73-year-old – who was otherwise healthy and active – unknowingly had Peripheral Artery Disease, caused by a build-up of plaque in his arteries causing them to narrow and stiffen.</p> <p>It wasn’t until a trip to the hospital emergency department years later that doctors would discover his aorta had expanded to more than twice the usual size and was at risk of rupturing. He immediately underwent open heart surgery and has faced a lengthy recovery.</p> <p>The launch of <a href="https://www.hri.org.au/our-research/centreforpad" target="_blank" rel="noopener">The Centre for Peripheral Artery Disease</a> heralds a new era of hope and progress in the fight against PAD. Through world-leading research, community engagement, and a commitment to patient-centred care, the CPAD is poised to make a profound impact on the lives of many Australians. As Assoc Prof Kavurma aptly put it, “By understanding more about this debilitating condition, we are paving the way for better health outcomes and a brighter future for all those affected by PAD.”</p> <p><em>Images: CPAD</em></p>

"Hero" teens steer bus to safety after driver has a heart attack

<p>Two teenagers have worked together to steer a school bus to safety after the driver had a heart attack. </p> <p>The pair were among 20 other students from Aquinas College, who were on board the bus yesterday afternoon when the 70-year-old driver had the medical episode. </p> <p>A 15-year-old girl, not yet old enough to drive, and Daniel Knight, a year 12 student sprung to action to stop the bus. </p> <p>"We were only going like five [kilometres an hour], 10 k's, so I was like I better just stop the bus before it gets any worse," Knight said. </p> <p>"She opened the door up, she was calming everyone down."</p> <p>Bennet Rogers, a student on the bus  recalled the moment the incident happened. </p> <p>"Us students on the bus, we didn't know what was happening and everyone was screaming," Rogers said. </p> <p>"She had to steer the bus so we didn't crash into a building," he added. </p> <p>Knight and the 15-year-old girl's actions have been commended by the school in a letter to their parents. </p> <p>The bus driver remains in hospital and is recovering from surgery, and the principal has said that there would be an investigation into what happened. </p> <p>Many are calling for the teen girl to be recognised with a bravery award, with Queensland Premier Steven Miles telling <em>Nine News</em> he would personally nominate her. </p> <p>"She's a hero for that, definitely," another fellow student, Brodie Wilkinson, said.</p> <p>"I really hope she gets an award or something."</p> <p><em>Image: Nine News</em></p> <p> </p> <p> </p>

1 in 5 deaths are caused by heart disease, but what else are Australians dying from?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/garry-jennings-5307">Garry Jennings</a>, <a href="https://theconversation.com/institutions/university-of-sydney-841">University of Sydney</a></em></p> <p>Nobody dies in good health, at least in their final moments. But to think the causes of death are easy to count or that there is generally a single reason somebody passes is an oversimplification.</p> <p>In fact, in 2022, four out of five Australians had multiple conditions at the time of death listed on their death certificate, and almost one-quarter had five or more recorded. This is one of many key findings from a <a href="https://pp.aihw.gov.au/reports/life-expectancy-deaths/what-do-australians-die-from/contents/about">new report</a> from the Australian Institute of Health and Welfare (AIHW).</p> <p>The report distinguishes between three types of causes of death – underlying, direct, and contributory. An underlying cause is the condition that initiates the chain of events leading to death, such as having coronary heart disease. The direct cause of death is what the person died from (rather than with), like a heart attack. Contributory causes are things that significantly contributed to the chain of events leading to death but are not directly involved, like having high blood pressure. The report also tracks how these three types of causes can overlap in deaths involving multiple causes.</p> <p>In 2022 the top five conditions involved in deaths in Australia were coronary heart disease (20% of deaths), dementia (18%), hypertension, or high blood pressure (12%), cerebrovascular disease such as stroke (11.5%), and diabetes (11.4%).</p> <hr /> <p><iframe id="MzQHA" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/MzQHA/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>When the underlying cause of death was examined, the list was similar (coronary heart disease 10%, dementia 9%, cerebrovascular disease 5%, followed by COVID and lung cancer, each 5%). This means coronary heart disease was not just lurking at the time of death but also the major underlying cause.</p> <p>The direct cause of death however was most often a lower respiratory condition (8%), cardiac or respiratory arrest (6.5%), sepsis (6%), pneumonitis, or lung inflammation (4%) or hypertension (4%).</p> <h2>Why is this important?</h2> <p>Without looking at all the contributing causes of death, the role of important factors such as coronary heart disease, sepsis, depression, high blood pressure and alcohol use can be underestimated.</p> <p>Even more importantly, the various causes draw attention to the areas where we should be focusing public health prevention. The report also helps us understand which groups to focus on for prevention and health care. For example, the number one cause of death in women was dementia, whereas in men it was coronary heart disease.</p> <hr /> <p><iframe id="NosVz" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/NosVz/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>People aged under 55 tended to die from external events such as accidents and violence, whereas older people died against a background of chronic disease.</p> <hr /> <p><iframe id="1l3OS" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/1l3OS/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>We cannot prevent death, but we can prevent many diseases and injuries. And this report highlights that many of these causes of death, both for younger Australians and older, are preventable. The top five conditions involved in death (coronary heart disease, dementia, hypertension, cerebrovascular disease and diabetes) all share common risk factors such as tobacco use, high cholesterol, poor nutrition, physical inactivity, or are risk factors themselves, like hypertension or diabetes.</p> <hr /> <p><iframe id="7Eb8O" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/7Eb8O/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>Tobacco use, high blood pressure, being overweight or obese and poor diet were attributable to a combined 44% of all deaths in this report. This suggests a comprehensive approach to health promotion, disease prevention and management is needed.</p> <hr /> <p><iframe id="2MmGg" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/2MmGg/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>This should include strategies and programs encouraging eating a healthy diet, participating in regular physical activity, limiting or eliminating alcohol consumption, quitting smoking, and seeing a doctor for regular health screenings, such as the Medicare-funded <a href="https://www.heartfoundation.org.au/your-heart/heart-health-checks">Heart Health Checks</a>. Programs directed at accident prevention, mental health and violence, especially gender-related violence, will address untimely deaths in the young.<!-- Below is The Conversation's page counter tag.

Major TV star's 7-year-old undergoes third open heart surgery

<p>Jimmy Kimmel's seven-year-old son has undergone his third, and hopefully final open heart surgery after being born with congenital heart disease. </p> <p>In 2017, Jimmy <a href="https://www.youtube.com/watch?v=MmWWoMcGmo0" target="_blank" rel="noopener">revealed</a> that Billy was only three days old when had to undergo his first open heart surgery, after doctors found “a hole in the wall of the left and right side of his heart” that was preventing enough oxygen from reaching his blood. </p> <p>Billy was only seven months old when he had to undergo his second open heart surgery, and over the weekend he had to undergo his third major surgery at the Children's Hospital Los Angeles. </p> <p>A few days later, the TV host took to Instagram to share an update following his son's successful surgery. </p> <p>"We went into this experience with a lot of optimism and nearly as much fear and came out with a new valve inside a happy, healthy kid," Kimmel wrote, alongside a picture of his youngest son smiling in a hospital bed. </p> <p>He then thanked all the surgeons, doctors and other medical staff who "came through for us with immeasurable kindness and expertise." </p> <p>"Walking around this hospital, meeting parents at their most vulnerable, children in pain and the miracle workers who do everything in their considerable power to save them is a humbling experience," Kimmel continued.</p> <blockquote class="instagram-media" style="background: #FFF;

Step up: take the stairs to help your heart

<p>Climbing stairs is associated with a longer life, according to research presented this week at an annual meeting of Europe’s leading cardiologists.</p> <div class="copy"> <p>The systematic review of 9 previous studies covering nearly 500,000 participants investigated whether climbing stairs as a form of physical activity could play a role in reducing the risks of <a href="https://cosmosmagazine.com/science/biology/how-organ-on-a-chip-technology-is-revolutionising-the-way-we-study-cardiovascular-disease/">cardiovascular diseases</a> and premature death.</p> <p>Study author Dr Sophie Paddock, of the Norfolk and Norwich University Hospital Foundation Trust, UK, says: “if you have the choice of taking the stairs or the lift, go for the stairs as it will help your heart”.</p> <p>“Even brief bursts of physical activity have beneficial health impacts, and short bouts of stair climbing should be an achievable target to integrate into daily routines.”</p> <p>Cardiovascular diseases (CVDs) are a group of disorders of the hearth and blood vessels. They are the leading cause of non-communicable disease death globally, with 17.9m people estimated to have died of one in 2019 alone. Physical inactivity is one of the most important behavioural risk factors for developing CVDs. More than 1 in 4 adults do not meet the global <a href="https://www.who.int/news-room/fact-sheets/detail/physical-activity" target="_blank" rel="noreferrer noopener">recommended levels</a> of physical activity.</p> <p>The <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3049418/" target="_blank" rel="noreferrer noopener">meta-analysis</a> on the best available science  covered 480,479 individuals aged 35-84 years old. 53% of participants were women.</p> <p>Stair climbing was significantly associated with a 24% reduced risk of dying from any cause and a 39% lower likelihood of dying from cardiovascular disease, compared to not climbing stairs.</p> <p>It was also linked to a reduced <a href="https://cosmosmagazine.com/health/covid-19-impacts-on-cardiac-health/">risk of CVDs</a> including heart attack, heart failure and stroke.</p> <p>“Based on these results, we would encourage people to incorporate stair climbing into their day-to-day lives,” says Paddock.</p> <p>“Our study suggested that the more stairs climbed, the greater the benefits – but this needs to be confirmed. So, whether at work, home, or elsewhere, take the stairs.”</p> <p>The research was presented to <a href="https://www.escardio.org/Congresses-Events/Preventive-Cardiology" target="_blank" rel="noreferrer noopener">ESC Preventive Cardiology 2024</a>, an annual congress of the European Association of Preventive Cardiology in Greece this week.</p> <p><em>Image credits: Shutterstock </em></p> <div> <p align="center"><noscript data-spai="1"><em><img decoding="async" class="aligncenter size-full wp-image-198773" src="https://cdn.shortpixel.ai/spai/q_lossy+ret_img+to_auto/cosmosmagazine.com/wp-content/uploads/2023/12/MICROSCOPIC-TO-TELESCOPIC__Embed-graphic-720x360-1.jpg" data-spai-egr="1" width="600" alt="Buy cosmos print magazine" title="step up: take the stairs to help your heart 2"></em></noscript></p> </div> <p><em><!-- Start of tracking content syndication.

Menopause can bring increased cholesterol levels and other heart risks. Here’s why and what to do about it

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/treasure-mcguire-135225">Treasure McGuire</a>, <a href="https://theconversation.com/institutions/the-university-of-queensland-805">The University of Queensland</a></em></p> <p>Menopause is a natural biological process that marks the end of a woman’s reproductive years, typically between 45 and 55. As women approach or experience menopause, common “change of life” <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9244939/">concerns</a> include hot flushes, sweats and mood swings, brain fog and fatigue.</p> <p>But many women may not be aware of the <a href="https://pubmed.ncbi.nlm.nih.gov/32705886/">long-term effects</a> of menopause on the heart and blood vessels that make up the cardiovascular system. Heart disease accounts for <a href="http://world-heart-federation.org/what-we-do/women-cvd/">35% of deaths</a> in women each year – more than all cancers combined.</p> <p>What should women – and their doctors – know about these risks?</p> <h2>Hormones protect hearts – until they don’t</h2> <p>As early as 1976, the <a href="https://pubmed.ncbi.nlm.nih.gov/970770/">Framingham Heart Study</a> reported more than twice the rates of cardiovascular events in postmenopausal than pre-menopausal women of the same age. Early menopause (younger than age 40) also <a href="https://pubmed.ncbi.nlm.nih.gov/25331207/">increases heart risk</a>.</p> <p>Before menopause, women tend to be protected by their circulating hormones: oestrogen, to a lesser extent progesterone and low levels of testosterone.</p> <p>These sex hormones help to relax and dilate blood vessels, reduce inflammation and <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10503403/">improve lipid (cholesterol) levels</a>. From the mid-40s, a decline in these hormone levels can <a href="https://pubmed.ncbi.nlm.nih.gov/10362825/">contribute to unfavourable changes</a> in cholesterol levels, blood pressure and weight gain – all risk factors for heart disease.</p> <h2>4 ways hormone changes impact heart risk</h2> <p><strong>1. Dyslipidaemia</strong>– Menopause often involves <a href="https://pubmed.ncbi.nlm.nih.gov/38002671/">atherogenic changes</a> – an unhealthy imbalance of lipids in the blood, with higher levels of total cholesterol, triglycerides, and low-density lipoprotein (LDL-C), dubbed the “bad” cholesterol. There are also reduced levels of high-density lipoprotein (HDL-C) – the “good” cholesterol that helps remove LDL-C from blood. These changes are a <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10503403/">major risk factor for heart attack or stroke</a>.</p> <p><strong>2. Hypertension</strong> – Declines in oestrogen and progesterone levels during menopause contribute to narrowing of the large blood vessels on the heart’s surface, arterial stiffness and <a href="https://pubmed.ncbi.nlm.nih.gov/35722103/">raise blood pressure</a>.</p> <p><strong>3. Weight gain</strong> – Females are born with one to two million eggs, which develop in follicles. By the time they <a href="https://www.thewomens.org.au/health-information/fertility-information/getting-pregnant/ovulation-and-conception">stop ovulating</a> in midlife, fewer than 1,000 remain. This depletion progressively changes fat distribution and storage, from the hips to the waist and abdomen. Increased waist circumference (greater than 80–88 cm) has been <a href="https://pubmed.ncbi.nlm.nih.gov/18359190/">reported to contribute to heart risk</a> – though it is <a href="https://theconversation.com/good-news-midlife-health-is-about-more-than-a-waist-measurement-heres-why-226019">not the only factor to consider</a>.</p> <p><strong>4. Comorbidities</strong> – Changes in body composition, sex hormone decline, increased food consumption, weight gain and sedentary lifestyles impair the body’s ability to effectively use insulin. This <a href="https://pubmed.ncbi.nlm.nih.gov/11133069/">increases the risk</a> of developing metabolic syndromes such as type 2 diabetes.</p> <p>While risk factors apply to both genders, hypertension, smoking, obesity and type 2 diabetes confer a greater relative risk for heart disease in women.</p> <h2>So, what can women do?</h2> <p>Every woman has a different level of baseline cardiovascular and metabolic risk pre-menopause. This is based on their genetics and family history, diet, and lifestyle. But all women can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8351755/">reduce their post-menopause heart risk with</a>:</p> <ul> <li>regular moderate intensity exercise such as brisk walking, pushing a lawn mower, riding a bike or water aerobics for 30 minutes, four or five times every week</li> <li>a healthy heart diet with smaller portion sizes (try using a smaller plate or bowl) and more low-calorie, nutrient-rich foods such as vegetables, fruit and whole grains</li> <li>plant sterols (unrefined vegetable oil spreads, nuts, seeds and grains) each day. A review of 14 clinical trials found plant sterols, at doses of at least 2 grams a day, produced an average reduction in serum LDL-C (bad cholesterol) of about 9–14%. This could reduce the risk of heart disease by <a href="https://pubmed.ncbi.nlm.nih.gov/10731187/">25% in two years</a></li> <li>less unhealthy (saturated or trans) fats and more low-fat protein sources (lean meat, poultry, fish – especially oily fish high in omega-3 fatty acids), legumes and low-fat dairy</li> <li>less high-calorie, high-sodium foods such as processed or fast foods</li> <li>a reduction or cessation of smoking (nicotine or cannabis) and alcohol</li> <li>weight-gain management or prevention.</li> </ul> <h2>What about hormone therapy medications?</h2> <p>Hormone therapy remains the most effective means of <a href="https://pubmed.ncbi.nlm.nih.gov/15495039/">managing hot flushes and night sweats</a> and is beneficial for <a href="https://pubmed.ncbi.nlm.nih.gov/18418063/">slowing the loss of bone mineral density</a>.</p> <p>The decision to recommend oestrogen alone or a combination of oestrogen plus progesterone hormone therapy depends on whether a woman has had a hysterectomy or not. The choice also depends on whether the hormone therapy benefit outweighs the woman’s disease risks. Where symptoms are bothersome, hormone therapy has <a href="https://pubmed.ncbi.nlm.nih.gov/33841322/">favourable or neutral effects on coronary heart disease risk</a> and medication risks are low for healthy women younger than 60 or within ten years of menopause.</p> <p>Depending on the level of stroke or heart risk and the response to lifestyle strategies, some women may also require medication management to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8351755/">control high blood pressure or elevated cholesterol levels</a>. Up until the early 2000s, women were underrepresented in most outcome trials with lipid-lowering medicines.</p> <p>The <a href="https://pubmed.ncbi.nlm.nih.gov/25579834/">Cholesterol Treatment Trialists’ Collaboration</a> analysed 27 clinical trials of statins (medications commonly prescribed to lower cholesterol) with a total of 174,000 participants, of whom 27% were women. Statins were about as effective in women and men who had similar risk of heart disease in preventing events such as stroke and heart attack.</p> <p>Every woman approaching menopause should ask their GP for a 20-minute <a href="https://www.health.gov.au/news/heart-health">Heart Health Check</a> to help better understand their risk of a heart attack or stroke and get tailored strategies to reduce it.<!-- End of code.

Two lifesaving heart medicines added to the PBS

<p>Two lifesaving heart medicines have been added to the Pharmaceutical Benefits Scheme (PBS).</p> <p>Previous treatments for the two kinds of heart disorder cardiomyopathy, which affect around 4800 Australians, previously cost patients up to $122,000.</p> <p>Now, with the addition of it to the PBS, patients will only have to pay $31.60 per script, or just $7.70 with a concession card.</p> <p>One of the medications added to the list is Tafamadis (also known as Vyndamax), which is used to treat transthyretin amyloid cardiomyopathy - a rare heart disease that can present as shortness of breath and fatigue.</p> <p>The newly listed treatment slows the progression of the disease and prevents the build-up of thickened heart muscles, and is the most expensive medication costing patients around $122,000 for a year of treatment without the government subsidy. </p> <p>Camzyos, the treatment for hypertrophic cardiomyopathy, which affects around 3600 Australians and previously cost around $30,000 per year of treatment, will also be subsidised.</p> <p>"It's vitally important that Australians have ready and affordable access to the latest treatments," Federal Health Minister Mark Butler said.</p> <p>"By listing Vyndamax and Camzyos on the PBS we're giving patients and their doctors new options for treatment at an affordable price.</p> <p>"It's part of the Albanese Government's commitment to keep medicines cheaper for Australians."</p> <p><em>Image: Nine</em></p>

<p>The girlfriend of one of the Perth brothers killed in Mexico has paid tribute to her partner, just days after the news of his tragic death broke. </p> <p>Brothers Callum and Jake Robinson were travelling in Mexico with their American friend, Jack Carter Rhoad, when they went missing. </p> <p>Days after their disappearance, their bodies were found in a well and identified by their families. </p> <p>Authorities believe all three were shot in the head in a botched robbery by thieves who wanted their ute for spare parts.</p> <p>Now, Callum's girlfriend Emily Horwath has shared a heart-breaking tribute to her partner, sharing loved up photos of the couple on Instagram.</p> <p>Horwath said her partner was “one of one”, writing, “My heart is shattered into a million pieces.”</p> <p>“I don’t have the words right now. I will love you forever.”</p> <p>Emily also shared the link to a <a href="https://www.gofundme.com/f/callum-and-jake-robinson-support-the-robinson-family?utm_campaign=p_cp+fundraiser-sidebar&amp;utm_content=anyword&amp;utm_medium=copy_link_all&amp;utm_source=customer" target="_blank" rel="noopener">GoFundMe</a> page made to support the Robinson family, which has raised almost $400,000. </p> <p>Other close friends remembered the 33-year-old as “one of the most beautiful and loving souls”.</p> <p>“This world lost one of its kindest, silliest and most genuine souls this week,” one friend said.</p> <p>“Heaven welcomed the purest, kindest angel,” another said.</p> <p>A friend of Jake paid tribute to the 30-year-old, saying, “it was an honour to have known and worked with you.”</p> <p><em>Image credits: Instagram </em></p>

What are heart rate zones, and how can you incorporate them into your exercise routine?

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/hunter-bennett-1053061">Hunter Bennett</a>, <a href="https://theconversation.com/institutions/university-of-south-australia-1180">University of South Australia</a></em></p> <p>If you spend a lot of time exploring fitness content online, you might have come across the concept of heart rate zones. Heart rate zone training has become more popular in recent years partly because of the boom in wearable technology which, among other functions, allows people to easily track their heart rates.</p> <p><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6537749/">Heart rate zones</a> reflect different levels of intensity during aerobic exercise. They’re most often based on a percentage of your maximum heart rate, which is the highest number of beats your heart can achieve per minute.</p> <p>But what are the different heart rate zones, and how can you use these zones to optimise your workout?</p> <h2>The three-zone model</h2> <p>While there are several models used to describe heart rate zones, the most common model in the scientific literature is the <a href="https://journals.humankinetics.com/view/journals/ijspp/9/1/article-p100.xml">three-zone model</a>, where the zones may be categorised as follows:</p> <ul> <li> <p>zone 1: 55%–82% of maximum heart rate</p> </li> <li> <p>zone 2: 82%–87% of maximum heart rate</p> </li> <li> <p>zone 3: 87%–97% of maximum heart rate.</p> </li> </ul> <p>If you’re not sure what your maximum heart rate is, it can be calculated using <a href="https://www.jacc.org/doi/full/10.1016/S0735-1097%2800%2901054-8">this equation</a>: 208 – (0.7 × age in years). For example, I’m 32 years old. 208 – (0.7 x 32) = 185.6, so my predicted maximum heart rate is around 186 beats per minute.</p> <p>There are also other models used to describe heart rate zones, such as the <a href="https://journals.humankinetics.com/view/journals/ijspp/14/8/article-p1151.xml">five-zone model</a> (as its name implies, this one has five distinct zones). These <a href="https://journals.humankinetics.com/view/journals/ijspp/9/1/article-p100.xml">models</a> largely describe the same thing and can mostly be used interchangeably.</p> <h2>What do the different zones involve?</h2> <p>The three zones are based around a person’s <a href="https://link.springer.com/article/10.2165/00007256-200939060-00003">lactate threshold</a>, which describes the point at which exercise intensity moves from being predominantly aerobic, to predominantly anaerobic.</p> <p>Aerobic exercise <a href="https://www.healthline.com/health/fitness-exercise/difference-between-aerobic-and-anaerobic">uses oxygen</a> to help our muscles keep going, ensuring we can continue for a long time without fatiguing. Anaerobic exercise, however, uses stored energy to fuel exercise. Anaerobic exercise also accrues metabolic byproducts (such as lactate) that increase fatigue, meaning we can only produce energy anaerobically for a short time.</p> <p>On average your lactate threshold tends to sit around <a href="https://www.tandfonline.com/doi/full/10.2147/OAJSM.S141657">85% of your maximum heart rate</a>, although this varies from person to person, and can be <a href="https://journals.physiology.org/doi/full/10.1152/japplphysiol.00043.2013">higher in athletes</a>.</p> <p>In the three-zone model, each zone loosely describes <a href="https://www.frontiersin.org/journals/physiology/articles/10.3389/fphys.2015.00295/full">one of three types of training</a>.</p> <p><strong>Zone 1</strong> represents high-volume, low-intensity exercise, usually performed for long periods and at an easy pace, well below lactate threshold. Examples include jogging or cycling at a gentle pace.</p> <p><strong>Zone 2</strong> is threshold training, also known as tempo training, a moderate intensity training method performed for moderate durations, at (or around) lactate threshold. This could be running, rowing or cycling at a speed where it’s difficult to speak full sentences.</p> <p><strong>Zone 3</strong> mostly describes methods of high-intensity interval training, which are performed for shorter durations and at intensities above lactate threshold. For example, any circuit style workout that has you exercising hard for 30 seconds then resting for 30 seconds would be zone 3.</p> <h2>Striking a balance</h2> <p>To maximise endurance performance, you need to strike a balance between doing enough training to elicit positive changes, while avoiding over-training, injury and burnout.</p> <p>While zone 3 is thought to produce the largest improvements in <a href="https://www.sciencedirect.com/science/article/pii/S1440244018309198">maximal oxygen uptake</a> – one of the best predictors of endurance performance and overall health – it’s also the most tiring. This means you can only perform so much of it before it becomes too much.</p> <p>Training in different heart rate zones improves <a href="https://citeseerx.ist.psu.edu/document?repid=rep1&amp;type=pdf&amp;doi=38c07018c0636422d9d5a77316216efb3c10164f">slightly different physiological qualities</a>, and so by spending time in each zone, you ensure a <a href="https://link.springer.com/article/10.1007/bf00426304">variety of benefits</a> for performance and health.</p> <h2>So how much time should you spend in each zone?</h2> <p>Most <a href="https://www.frontiersin.org/articles/10.3389/fspor.2023.1258585/full">elite endurance athletes</a>, including runners, rowers, and even cross-country skiers, tend to spend most of their training (around 80%) in zone 1, with the rest split between zones 2 and 3.</p> <p>Because elite endurance athletes train a lot, most of it needs to be in zone 1, otherwise they risk injury and burnout. For example, some runners accumulate <a href="https://journals.humankinetics.com/view/journals/ijsnem/22/5/article-p392.xml?content=pdf">more than 250 kilometres per week</a>, which would be impossible to recover from if it was all performed in zone 2 or 3.</p> <p>Of course, most people are not professional athletes. The <a href="https://www.who.int/news-room/fact-sheets/detail/physical-activity">World Health Organization</a> recommends adults aim for 150–300 minutes of moderate intensity exercise per week, or 75–150 minutes of vigorous exercise per week.</p> <p>If you look at this in the context of heart rate zones, you could consider zone 1 training as moderate intensity, and zones 2 and 3 as vigorous. Then, you can use heart rate zones to make sure you’re exercising to meet these guidelines.</p> <h2>What if I don’t have a heart rate monitor?</h2> <p>If you don’t have access to a heart rate tracker, that doesn’t mean you can’t use heart rate zones to guide your training.</p> <p>The three heart rate zones discussed in this article can also be prescribed based on feel using a simple <a href="https://onlinelibrary.wiley.com/doi/10.1111/j.1600-0838.2004.00418.x">10-point scale</a>, where 0 indicates no effort, and 10 indicates the maximum amount of effort you can produce.</p> <p>With this system, zone 1 aligns with a 4 or less out of 10, zone 2 with 4.5 to 6.5 out of 10, and zone 3 as a 7 or higher out of 10.</p> <p>Heart rate zones are not a perfect measure of exercise intensity, but can be a useful tool. And if you don’t want to worry about heart rate zones at all, that’s also fine. The most important thing is to simply get moving.<!-- Below is The Conversation's page counter tag.

Our housing system is broken and the poorest Australians are being hardest hit

<div class="theconversation-article-body"> <p><em><a href="https://theconversation.com/profiles/rachel-ong-viforj-113482">Rachel Ong ViforJ</a>, <a href="https://theconversation.com/institutions/curtin-university-873">Curtin University</a></em></p> <p>Just when we think the price of rentals could not get any worse, this week’s <a href="https://www.anglicare.asn.au/publications/2023-rental-affordability-snapshot/">Rental Affordability Snapshot</a> by Anglicare has revealed low-income Australians are facing a housing crisis like never before.</p> <p>In fact, if you rely on the <a href="https://www.servicesaustralia.gov.au/youth-allowance">Youth Allowance</a>, there is not a single rental property across Australia you can afford this week.</p> <h2>How did rental affordability get this bad?</h2> <p>Several post-COVID factors have been blamed, including our preference for <a href="https://www.rba.gov.au/publications/bulletin/2023/jun/new-insights-into-the-rental-market.html">more space, the return of international migrants</a>, and <a href="https://www.corelogic.com.au/news-research/news/2023/could-the-peak-in-interest-rates-signal-an-end-to-rising-rents">rising interest rates</a>.</p> <p>However, the rental affordability crisis pre-dates COVID.</p> <p>Affordability has been steadily declining for decades, as successive governments have failed to make shelter more affordable for low-to-moderate income Australians.</p> <h2>The market is getting squeezed at both ends</h2> <p>At the lower end of the rental sector, the growth in the supply of social housing persistently lags behind demand, trending at under <a href="https://povertyandinequality.acoss.org.au/data/annual-growth-rates-social-housing-stock-and-population-2011-2020/">one-third</a> the rate of population growth.</p> <hr /> <p><iframe id="OA0cS" class="tc-infographic-datawrapper" style="border: none;" src="https://datawrapper.dwcdn.net/OA0cS/" width="100%" height="400px" frameborder="0"></iframe></p> <hr /> <p>This has forced growing numbers of low-income Australians to seek shelter in the private rental sector, where they face intense competition from higher-income renters.</p> <p>At the upper end, more and more aspiring home buyers are getting <a href="https://www.tandfonline.com/doi/full/10.1080/03085147.2021.2003086">locked out</a> of home ownership.</p> <p>A recent <a href="https://www.ahuri.edu.au/sites/default/files/documents/2024-02/AHURI-Final-Report-416-Affordable-private-rental-supply-and-demand-short-term-disruption.pdf">study</a> found more households with higher incomes are now renting.</p> <p>Households earning <a href="https://www.ahuri.edu.au/sites/default/files/documents/2024-02/AHURI-Final-Report-416-Affordable-private-rental-supply-and-demand-short-term-disruption.pdf">$140,000</a> a year or more (in 2021 dollars) accounted for just 8% of private renters in 1996. By 2021, this tripled to 24%. No doubt, this crowds out lower-income households who are now facing a shortage of affordable homes to rent.</p> <h2>Why current policies are not working</h2> <p>Worsening affordability in the private rental sector highlights a housing system that is broken. Current policies just aren’t working.</p> <p>While current policies focus on supply, more work is needed including fixing <a href="https://theconversation.com/governments-are-pouring-money-into-housing-but-materials-land-and-labour-are-still-in-short-supply-205471">labour shortages</a> and providing greater <a href="https://theconversation.com/people-want-and-need-more-housing-choice-its-about-time-governments-stood-up-to-deliver-it-122390">stock diversity</a>.</p> <p>The planning system plays a critical role and <a href="https://theconversation.com/confusing-and-not-delivering-enough-developers-and-councils-want-new-affordable-housing-rules-139762">zoning rules</a> can be reformed to support the supply of more affordable options.</p> <p>However, the housing affordability challenge is not solely a supply problem. There is also a need to respond to the <a href="https://theconversation.com/home-prices-are-climbing-alright-but-not-for-the-reason-you-might-think-158776">super-charged demand</a> in the property market.</p> <p>An overheated market will undoubtedly place intense pressure on the rental sector because aspiring first home buyers are forced to rent for longer, as house prices soar at a rate unmatched by their wages.</p> <p>Yet, governments continue to resist calls for winding back the <a href="https://www.abc.net.au/news/2024-02-15/ken-henry-australias-tax-system-in-worse-position-after-15-years/103465044">generous tax concessions</a> enjoyed by multi-property owners.</p> <p>The main help available to low-income private renters - the Commonwealth Rent Assistance scheme - is <a href="https://theconversation.com/1-billion-per-year-or-less-could-halve-rental-housing-stress-146397">poorly targeted</a> with nearly one in five low-income renters who are in rental stress deemed ineligible, while another one in four receive it despite not being in rental stress.</p> <h2>Can affordable housing occur naturally?</h2> <p>Some commentators support the theory of <a href="https://www.ahuri.edu.au/sites/default/files/documents/2022-09/Executive-Summary-FR387-Filtering-as-a-source-of-low-income-housing-in-Australia-conceptualisation-and-testing.pdf">filtering</a> - a market-based process by which the supply of new dwellings in more expensive segments creates additional supply of dwellings for low-income households as high-income earners vacate their former dwellings.</p> <p>Proponents of filtering argue building more housing anywhere - even in wealthier ends of the property market - will eventually improve affordability across the board because lower priced housing will trickle down to the poorest households.</p> <p>However, the persistent affordability crisis low-income households face and the rise in homelessness are crucial signs filtering <a href="https://cloud.3dissue.com/122325/122578/143598/WhyNewSupplyisnotExpandingHousingOptionsfortheHomeless/html5/index.html?page=1&amp;noflash">does not work well</a> and <a href="https://www.ahuri.edu.au/sites/default/files/documents/2022-09/AHURI-Final-Report-387-Filtering-as-a-source-of-low-income-housing-in-Australia-conceptualisation-and-testing.pdf">cannot be relied upon</a> to produce lower cost housing.</p> <h2>Location, location, location</h2> <p>Location does matter, if we expect building new housing to work for low-income individuals.</p> <p>What is needed is a steady increase of affordable, quality housing in areas offering low-income renters the same access to jobs and amenities as higher-income households.</p> <p>The <a href="https://treasury.gov.au/housing-policy/accord#:%7E:text=The%20Accord%20includes%20an%20initial,5%20years%20from%20mid%E2%80%912024.">National Housing Accord</a> aims to deliver 1.2 million new dwellings over five years from mid-2024. But it must ensure these are “well-located” for people who need affordable housing, as suggested in the accord.</p> <p>Recent <a href="https://www.tandfonline.com/doi/full/10.1080/02673037.2023.229051">modelling</a> shows unaffordable housing and poor neighbourhoods both negatively affect mental health, reinforcing the need to provide both affordable and well-located housing.</p> <h2>The upcoming budget</h2> <p>While the <a href="https://www.dss.gov.au/sites/default/files/documents/05_2023/payments-cra_budget_fact_sheet_fa_0.pdf">15% increase</a> in the maximum rent assistance rate was welcomed in the last budget, the program is long overdue for a major restructure to target those in rental stress.</p> <p>Also, tax concessions on second properties should be wound back to reduce competition for those struggling to buy their first home. This would eventually help ease affordability pressures on low-income renters as more higher-income renters <a href="https://onlinelibrary.wiley.com/doi/abs/10.1111/1467-8454.12335">shift into homeownership</a>.</p> <p>The potential negative impacts on rental supply can be mitigated by careful design of tax and other changes that guard against market destabilisation concerns.</p> <p>Overall, housing affordability solutions have to be multi-faceted. The housing system is badly broken and meaningful repair cannot be achieved unless policymakers are willing to confront both supply and demand challenges.<!-- Below is The Conversation's page counter tag.
