World Heart Day 2026 is run by the World Heart Federation on Tuesday, 29 September. The federation uses the date to press the message that most deaths from heart disease are preventable.
Death rates from coronary heart disease have dropped by close to 90% since their peak in 1968, but cardiovascular disease was still the underlying cause of 42,300 deaths in 2024 and it remains a leading cause of death. Australia has reduced its death rate from heart disease across two generations, and the burden here remains heavy.
What is World Heart Day?
World Heart Day is an annual awareness campaign organised by the World Heart Federation. WHF established the day in 1999 alongside the World Health Organization, and the first one took place on 24 September 2000. For its first decade the day was observed on the last Sunday in September. The WHF fixed it to 29 September from 2011, and World Heart Day 2026 continues on that same date.
The subject of the day is cardiovascular disease (CVD), the broad term for conditions which affect your heart and blood vessels. Coronary heart disease, stroke, and heart failure are the most common forms, and the term also covers atrial fibrillation, peripheral arterial disease, rheumatic heart disease, and congenital heart disease.
Member organisations across the federation’s network, including Australia’s Heart Foundation, use the date to raise awareness of cardiovascular disease, publish free education resources, and press governments on cardiovascular health policy. Communities celebrate World Heart Day with group walks, public talks, and workplace events, and the federation asks ordinary people to learn the warning signs and take action to keep their heart healthy.
World Heart Day 2026: The Date, Theme, and Focus
The theme of World Heart Day 2026 is Don’t Miss a Beat. The focus is the symptoms of heart disease that go unnoticed until treatment becomes urgent. The World Heart Federation has split the campaign into three parts:
- See the signs. Warning signs of cardiovascular disease can be easily missed. High blood pressure can develop with no symptoms at all until a heart attack occurs, and half of babies born with congenital heart disease are not diagnosed at birth.
- Protect your heart. Around 80% of CVD deaths come from risks that can be prevented or managed. Moving more and making a heart-healthy swap at dinner both improve heart health when they continue across months and years.
- Demand action. Despite the global death toll, cardiovascular disease is overlooked by many. Fewer than 20 countries have a national plan, and the 2026 campaign includes a global open letter calling on leaders to put one in place.
The 2026 campaign includes several activities. An Are You Heart Smart? quiz covers common myths, hidden symptoms, and risk factors people may not recognise, and it is available on the World Heart Day website and app. The Keep the Beat challenge invites people to pledge to become more active through September, with pledges last year ranging from walking to yoga to rock climbing. A new Heart Health Champions initiative recognises people and companies who help spread heart health messages on social media, and the campaign hashtag is #DontMissABeat.
Cardiovascular Disease in Australia: How Many People Die of Heart Disease and Stroke
The global figures behind World Heart Day 2026 combine decades of improvement with a toll that remains large. An estimated 1.3 million Australian adults, 6.4% of the adult population, were living with one or more heart, stroke, or vascular conditions in 2022 to 2024. Of those, 593,000 reported coronary heart disease, which includes angina and heart attack.
Coronary heart disease was the underlying cause of 16,300 deaths in 2024, and stroke caused 7,900, which was 19% of all cardiovascular deaths. Cardiovascular disease as a whole accounted for 23% of Australian deaths that year. There were an estimated 57,100 acute coronary events among people aged 25 and over in 2023, equivalent to around 156 a day, and an estimated 41,100 stroke events, about 113 a day. Someone is hospitalised for a heart attack every 9 minutes in Australia, and that one in five people do not know the warning signs of one.
The rate of acute coronary events dropped by 61% between 2001 and 2023, with a slightly larger decline for women at 64% than for men at 60%. Stroke event rates dropped by 30% over the same period, and the age-standardised stroke death rate has dropped by 80% since 1980. Cardiovascular disease accounted for almost 12% of Australia’s total disease burden in 2024, and 75% of that burden came from years of life lost to premature death rather than from years lived with illness.
Heart Disease Risk Factors
High blood pressure means your blood pushes against your artery walls harder than it should. That pressure damages the lining of your blood vessels and forces your heart to work harder, which reduces how well it pumps. A blood pressure measurement taken by a health professional is the only way most people find out they have an issue with blood pressure.
High cholesterol increases plaque, which is made of fat, cholesterol, and other substances that collect inside your coronary arteries and narrow them. A heart attack happens when a piece of that plaque breaks open, a clot forms on it, and blood flow to the heart stops.
Smoking damages your blood vessels and makes clots more likely, and quitting lowers your risk over time. Type 2 diabetes and chronic kidney disease both raise your risk of cardiovascular disease enough that doctors treat them as risk factors in their own right. Excess weight around your middle adds to blood pressure, blood sugar, and cholesterol at the same time.
Some risk factors cannot be changed, but they still affect what you should do. Your age, your sex, and your family history all feed into a risk calculation, with family history defined as coronary heart disease or stroke in a first-degree female relative before 65 or a first-degree male relative before 55.
Improving Your Cardiovascular Health
Australian guidance on the lifestyle changes World Heart Day 2026 promotes can reduce your risk of heart attack and stroke. The national movement recommendations for adults aged 18 to 64 ask for regular moderate to vigorous physical activity for 30 minutes or more on most days, muscle-strengthening activities on two or more days each week, functional activities for mobility, balance, and coordination on three or more days each week, and several hours of light activity daily. Breaking up long stretches of sitting counts as well.
Diet changes that support heart health are consistent across Australian and international guidance. A balanced diet rich in fruits, vegetables, wholegrains, legumes, and unsalted nuts, with less salt, less added sugar, and less saturated fat, addresses the dietary risks that account for 32% of the Australian cardiovascular burden. Cutting back on alcohol lowers blood pressure and reduces your risk of atrial fibrillation, an irregular heart rhythm that raises stroke risk.
Booking a Heart Health Check With Your GP
The most concrete thing an adult can do for World Heart Day 2026 is book a Heart Health Check with their own GP. A Heart Health Check estimates your chance of a heart attack or stroke over the next five years and gives your doctor something specific to act on. Your GP will:
- collect your medical history
- conduct a basic physical examination
- start any treatment or referrals your results call for
- put a management plan in place
- give you preventive health care advice and information
Your results go into the Australian CVD risk calculator, which combines your age, sex, smoking status, blood pressure and cholesterol, diabetes status, and postcode into a five-year risk estimate. The calculator sorts that estimate into three categories:
- low, meaning under 5% risk over five years
- intermediate, meaning 5% to under 10%
- high, meaning 10% or above
Your category then shapes what happens next, from lifestyle advice alone through to blood pressure and cholesterol medication. Reclassification factors including coronary artery calcium score, chronic kidney disease, family history, ethnicity, and severe mental illness can move you into a different category when your calculated risk is close to a threshold.
Your Next Step Before September 29th
What World Heart Day 2026 achieves depends on what you do with it. Our first aid course awards nationally recognised statements of attainment in HLTAID009 Provide cardiopulmonary resuscitation, HLTAID010 Provide basic emergency life support, and HLTAID011 Provide first aid. When 29 September comes around, it stops being a day about statistics and becomes the day you had already done something about them.
FAQs
How Long Should You Perform CPR?
Continue CPR until the person responding or breathing normally, a health care professional takes over, or it becomes impossible for you to continue through exhaustion.
Can You Give Aspirin to Someone Having a Heart Attack?
Yes, you can give an adult with heart attack symptoms 300 mg of aspirin, unless they are allergic to it or a doctor has told them not to take it. Have them chew the tablet rather than swallow it whole. Do not give aspirin to anyone under 12 years of age.
Does the Flu Raise Your Risk of a Heart Attack?
Yes, your chance of a heart attack in the week after a flu infection is around six times higher than usual. Influenza vaccination lowers the risk of a heart event for up to a year in people with existing cardiovascular disease, and also lowers it in people without any.
