Summary

Women experience first-ever strokes differently than men, often at an older age with distinct risk factors and poorer outcomes. Targeted prevention strategies, especially for hypertension and atrial fibrillation in women, are crucial.

Area of Science:

  • Neurology
  • Epidemiology
  • Vascular Medicine

Background:

  • Limited research exists on sex-specific differences in stroke.
  • Understanding these differences is vital for effective stroke management and prevention.

Purpose of the Study:

  • To investigate sex-based disparities in first-ever acute stroke patients.
  • To analyze differences in vascular risk factors, clinical presentation, stroke subtypes, and outcomes between men and women.

Main Methods:

  • A cohort of 1581 first-ever acute stroke patients was analyzed.
  • Data collected included sex, age, risk factors, clinical symptoms, stroke type, treatment, and outcomes.
  • Statistical analysis was performed to identify significant sex differences.

Main Results:

  • Women were older on average and had higher rates of hypertension and cardioembolic stroke.
  • Men showed higher prevalence of alcohol overuse, smoking, and peripheral vascular disease.
  • Women experienced more aphasia, visual field deficits, and dysphagia, and had worse outcomes post-stroke.

Conclusions:

  • Sex significantly influences stroke characteristics, including age, risk factors, and subtype distribution.
  • Women face greater disability post-stroke, highlighting the need for sex-specific interventions.
  • Improved hypertension control and anticoagulant therapy for atrial fibrillation are recommended for stroke prevention, particularly in women.
