Higher stroke risk among females with atrial fibrillation may be related to sex-based disparities in cardiovascular care, according to a new study from Women's College Hospital, the Peter Munk Cardiac Centre (PMCC) at University Health Network (UHN) and ICES.
Atrial fibrillation is a common type of irregular heart rhythm that is associated with a higher risk of stroke-;after the age of 40, one in four strokes are caused by AF. Previous studies have found that female sex is a risk factor for AF-associated stroke. Recent research suggested that females are only at higher risk than males with AF if they have another factor predisposing them to stroke .
The population-based cohort study, published in the European Heart Journal, analyzed health records for people aged 65 and older recently diagnosed with AF in Ontario, Canada. The cohort included 354,254 people , with an average age of 78 years. The study was made possible through the Early Career Women's Heart and Brain Health Chair and a National New Investigator Award from the Heart and Stroke Foundation of Canada.
