Understanding Atrial Fibrillation and Its Impact
Maryanne Bawden initially believed she was suffering from the flu when her husband urged her to visit the hospital. However, after undergoing scans, doctors revealed that she had experienced a stroke and was fortunate not to have become paralysed. This incident marked the beginning of her journey with a heart rhythm disorder known as atrial fibrillation.
Atrial Fibrillation is the most common type of arrhythmia, affecting approximately one in 10 Australians over the age of 70. It significantly increases the risk of stroke by up to five times. In fact, roughly a third of all strokes in Australia are linked to this condition.
“When I had my stroke, it was literally out of the blue. I didn’t even think I was having a stroke,” Mr. Bawden shared with AAP. “But had I not received medical treatment at that time, the results would have been fairly catastrophic. That was a reality check and motivated me to ensure I did everything possible to prevent another stroke.”
The Importance of Early Detection
Scientists at the Heart Research Institute and the University of Sydney are conducting a study aimed at helping people detect atrial fibrillation before it leads to a life-altering stroke. Across Australia, more than 600 individuals over the age of 70 have participated in a trial that could potentially lead to a national screening program, similar to those used for bowel and breast cancer.
Preliminary findings from the study have already identified previously undiagnosed cases of atrial fibrillation, which may have gone unnoticed until participants experienced a stroke. “Atrial fibrillation is often silent, as many people feel perfectly well and have no idea they have it,” said chief investigator Professor Ben Freedman OAM. “If we can find it earlier, we have a real opportunity to prevent those strokes from happening in the first place. The impact on individuals, families and the health system would be enormous.”
Managing the Condition
Ms. Bawden now manages her diagnosis with a blood pressure monitor, which helps her regulate her energy levels, medication, and receive proper supervision from a cardiologist. Initially shaken by the news, knowing exactly what condition she has and how to live with it has given her a sense of control.
“Prevention in all cases is better than trying to have a good outcome,” she said. “Now, I’m looking at life and valuing every day—as you do once you’ve had a bit of a shock.”
