Sex differences and risk factors in recurrent ischemic stroke

Area of Science:

• Neurology
• Cardiovascular Medicine
• Epidemiology

Background:

• Recurrent ischemic stroke (RIS) poses significant mortality risks.
• Secondary prevention is crucial for managing RIS.
• Existing research on sex differences in RIS risk factors is inconsistent.

Purpose of the Study:

• To investigate sex-based differences in clinical characteristics and risk factors for recurrent ischemic stroke.
• To identify independent risk factors for stroke recurrence in males.

Main Methods:

• Retrospective study of 787 patients with recurrent ischemic stroke.
• Comparison of demographic, clinical, and laboratory data between males and females.
• Multivariate logistic regression analysis to identify independent risk factors.

Main Results:

• Males were younger and had higher rates of smoking and alcohol consumption.
• Females exhibited higher prevalence of hypertension, diabetes mellitus, dyslipidemia, and overweight.
• Hypertension, alcohol use, smoking, and dyslipidemia were significant risk factors for recurrence in males.

Conclusions:

• Hypertension and dyslipidemia are common risk factors for both sexes.
• Smoking and alcohol cessation are recommended for males post-stroke.
• Diabetes is a significant risk factor for females, necessitating further research into sex-specific preventive strategies.
