Do men and women have different survival rates after ischemic stroke with atrial fibrillation?
After an ischemic stroke caused by atrial fibrillation, survival rates differ between men and women. Research shows that women have lower long-term survival, but the risk of having another stroke is similar for both sexes. These differences are important for planning treatment and follow-up care.
What the research says
A large population-based study in Germany tracked patients for 20 years and found that 5-year survival after a first ischemic stroke was lower in women (50.4%) than in men (59.2%) 11. This survival gap was especially wide for cardioembolic strokes, which are often linked to atrial fibrillation 11. The same study reported that 5-year survival for cardioembolic stroke was 38.2% in women versus 49.4% in men 11. However, the risk of stroke recurrence over 5 years did not differ significantly between sexes 11.
A separate study from China also found no significant difference in overall recurrence rates between men and women after a first ischemic stroke 10. That study identified different risk factors by sex: in women, good sleep was a strong protective factor against recurrence, while in men, atherosclerotic burden and coronary heart disease increased risk, and physical activity was protective 10.
A post-hoc analysis of the ATIS-NVAF trial, which included patients with nonvalvular atrial fibrillation and recent ischemic stroke, found that the composite outcome of cardiovascular death, recurrent stroke, and major bleeding did not differ significantly between women and men 4. However, that trial had a small number of women (25.2%) and may not have had enough statistical power to detect small differences 4.
What to ask your doctor
- Given my sex, what is my personal risk of long-term survival after a stroke with atrial fibrillation?
- Are there specific lifestyle changes, such as improving sleep or increasing physical activity, that could lower my risk of another stroke?
- Should my treatment plan for atrial fibrillation be adjusted based on my sex?
- How often should I have follow-up appointments to monitor for stroke recurrence?
- What are the warning signs of another stroke that I should watch for?
