Preventing stroke and assessing risk in women

Area of Science:

• Neurology
• Cardiology
• Women's Health

Background:

• Stroke incidence rises post-menopause, and while men have higher risk before 75, women's longer lifespan leads to greater overall incidence.
• Women with cerebrovascular disease often present with atypical symptoms, such as altered mental status, which is more common than in men.
• Atrial fibrillation (AF) and hypertension are more potent stroke risk factors in women than men, even in anticoagulated patients.

Purpose of the Study:

• To summarize the epidemiology and risk factors for ischaemic stroke in women.
• To highlight differences in stroke presentation and risk factors between men and women.
• To examine unique risk factors for stroke in women, including pregnancy-related conditions.

Main Methods:

• Review of existing literature on stroke in women.
• Analysis of epidemiological data comparing stroke risk in men and women.
• Identification and evaluation of specific risk factors prevalent in the female population.

Main Results:

• Women experience increased ischaemic stroke risk after menopause and have a higher overall incidence due to longer life expectancy.
• Atypical symptoms like altered mental status are more common in women with cerebrovascular disease.
• Atrial fibrillation confers a higher annual ischaemic stroke risk in women (6.2%) compared to men (4.2%), persisting even with anticoagulation.
• Pregnancy, particularly the third trimester and peripartum, along with hypertension in pregnancy (preeclampsia, eclampsia), significantly increases stroke risk.
• Preeclampsia and gestational diabetes are associated with elevated long-term stroke risk in women.

Conclusions:

• Stroke risk and presentation in women differ significantly from men, necessitating tailored prevention and treatment strategies.
• Pregnancy-related conditions represent unique and potent risk factors for both short-term and long-term stroke risk in women.
• Understanding these sex-specific differences is crucial for improving stroke outcomes in the female population.
