One in five adults in Australia can't name a heart attack symptom, finds study

New research has found one in five adults in Australia can't name any heart attack symptoms, and only around half report chest pain as a symptom. It has also helped inspire a new partnership working to increase awareness in at-risk areas.

Published in Heart, Lung and Circulation, the Monash University-led project examined awareness during and following the Heart Foundation's Warning Signs Campaign, which ran from 2010-2013.

The Warning Signs campaign improved people in Australia's awareness of heart attack symptoms, confidence to act and to call an ambulance if symptoms were experienced. This aligns with other evaluations of the campaign, which showed patients who had a heart attack and who saw the campaign acted fast.

The new cross-sectional study compared awareness across 2010-2014, during and immediately after the campaign, and 2015-2020. In total, 101,936 adults in Australia were surveyed. Looking at the ability of those aged 30-59 to name heart attack symptoms, awareness declined significantly in the years following the Warning Signs campaign.

Awareness of chest pain as a heart attack fell from 80 percent in 2010 to 57 percent in 2020. The proportion of respondents who could not name a single heart symptom increased from four percent to 20 percent.

Lead author Associate Professor Janet Bray, of the Monash University School of Public Health and Preventive Medicine, said the findings were "very alarming" and new approaches were needed to ensure people acted appropriately if symptoms occurred.

Associate Professor Bray said time was critical. "Every minute, more heart muscle dies and the chance of complications like cardiac arrest increases," she said. "Every Australian should be able to recognize heart attack symptoms and the need to respond quickly and call Triple Zero for an ambulance (000)."

The findings helped prompt the Heart Matters study, a partnership among Monash University, the Heart Foundation, Ambulance Victoria and the Victorian Government Department of Health. The trial is working to improve heart attack awareness in eight high-risk local government areas.

Heart Foundation Manager Clinical Evidence, Dr. Amanda Buttery, said Heart Matters aimed to improve personal risk awareness, heart symptom awareness and ambulance use in areas with known high heart attack rates and low ambulance use. "It involves community education sessions and reaching groups with known low warning sign awareness and ambulance use," she said.

Associate Professor Bray said some people in Australia were "definitely" at risk of serious illness or death due to their lack of heart attack knowledge. She said awareness was unlikely to have improved in the time since study finished in 2020, as public health messaging has been focused on COVID.

"A heart attack occurs due to a blockage in an artery in the heart, which means blood and oxygen can't get to part of the heart and that part starts to die," she said. "We have treatments in hospital that can reopen the blocked artery, and the quicker this can be done the less heart muscle that dies.

"This is why we need the public to know heart attack symptoms and to call an ambulance. Calling an ambulance allows treatment to start immediately and ensures that they can be taken to a hospital that offers the right treatment."

Ambulance Victoria Paramedic and Acting Director of Research and Evaluation, Dr. Ziad Nehme, welcomed the findings of the study.

"Our paramedics attend almost 60,000 patients every year with suspected heart attack symptoms, such as chest pain. Paramedics are best placed to diagnose and treat heart attacks in the community and are equipped to administer life-saving medications that can open a blocked artery in the heart," said Dr. Nehme. "Recognizing your symptoms early and calling Triple Zero (000) can make all the difference to your recovery."

Heart attacks at a glance

A heart attack is a sudden blockage of the blood supply to an area of the heart. This means that the heart muscle isn't getting the oxygen it needs to effectively pump blood to the rest of the body.

  • Every year 56,700 Australians have a heart attack or angina, equating to 155 events every day. Twice as many men experience heart attacks as women, and considerably more men die.
  • 93 percent more men are admitted to hospital for heart attacks than women.
  • Heart attacks cause almost one in 25 deaths. This equates to one person every 81 minutes, or on average 18 people every day (6500 a year).
  • Every day 157 people need hospital treatment due to a heart attack, or one every nine minutes.
  • Positively, the prevalence of heart attacks has been decreasing over time.

Warning signs of a heart attack

  • Pain, pressure or tightness in one or more of these areas: chest, arm(s), shoulder(s) or back, neck or jaw. You may also feel short of breath, dizzy, sweaty or sick.
  • Tell someone how you feel. If feeling worse or not better after 10 minutes, call an ambulance.

Men vs. women

While chest pain is the most common heart attack symptom in both women and men, women are more likely than men to experience non-chest .

Women are more likely to experience heart attack warning signs such as , , , cold sweats and pain or discomfort in the jaw, shoulders, arms or back. These are symptoms that can be mistaken for conditions such as the flu, overexertion, indigestion or just feeling run down rather than a life-threatening .
