Atrial fibrillation detection: Eye scans and new awareness campaigns

Atrial fibrillation (AFib), a heart rhythm condition that can increase stroke risk fivefold, remains largely undetected globally. A study published in PLOS Digital Health suggests that changes in the retina may signal an increased risk of AFib up to four years before a clinical diagnosis, potentially allowing routine eye exams to serve as cardiovascular screening tools.

In Australia, awareness of the condition is critically low. Research indicates that only 2% of Australians over 18 can correctly identify the four key signs of AFib. Furthermore, while many recognize a racing heartbeat, only 21% would seek immediate medical attention for the symptom, with 36% opting to wait and see if it resolves.

To combat this, the organization Hearts4heart has launched the ‘PULSE’ acronym to help the public remember warning signs: Pounding or racing heartbeat, Unusual tiredness, Light-headed or dizzy spells, Skipped or fluttering beats, and Elevated stroke risk if untreated. AFib affects an estimated 52.55 million people worldwide, often leading to serious complications such as heart failure, heart attack, and dementia.
