Atrial fibrillation, a common yet often unnoticed heart condition, significantly raises the risk of severe strokes among Australians. According to estimates, six Australians die each day from complications related to this condition, which can manifest with mild or absent symptoms. Research indicates that the prevalence of atrial fibrillation is set to double in the next 20 years among those aged 55 and over. Currently, more than half a million Australians are believed to be living with undiagnosed atrial fibrillation, often identified only after experiencing a stroke. The world’s largest clinical trial, led by Professor Ben Freedman in collaboration with the Heart Research Institute and the University of Sydney, has begun enrolling participants over 70 years old to monitor atrial fibrillation using at-home ECG devices. Despite the trial's promise, the Australian government has not yet committed to a national screening program, which could potentially reduce the incidence of strokes linked to this condition and alleviate pressure on aged care services.
