Summary
This study found that atrial fibrillation (AF) patients experience more severe ischemic strokes, with a higher incidence in females. Specific age groups showed increased stroke risk with AF.
Area of Science:
- Neurology
- Cardiology
- Epidemiology
Background:
- Atrial fibrillation (AF) is linked to a higher prevalence of severe ischemic stroke.
- Recent data suggest an increased frequency of stroke in females with AF.
Purpose of the Study:
- To compare clinical and laboratory features of ischemic stroke patients with and without AF.
- To evaluate AF-related stroke features by gender and age.
Main Methods:
- Retrospective analysis of 516 consecutive ischemic stroke patients, including 93 with AF.
- Statistical comparison of anamnestic, clinical, and laboratory data between AF and non-AF groups.
- Evaluation of AF patient data stratified by gender and age.
Main Results:
- Stroke severity is greater in patients with AF compared to non-AF patients.
- Stroke incidence with AF is higher in female patients.
- Increased stroke frequency with AF observed in males aged 60-69 and females aged 80-89.
Conclusions:
- Confirms greater stroke severity and higher female incidence in AF patients.
- Identifies specific age-gender groups with elevated AF-related stroke risk.
- Highlights hypertension and LVH in older females, and diabetes, alcohol, and smoking in middle-aged males as key risk factors.
