Insights
Women experienced more severe strokes and poorer outcomes compared to men. This study highlights significant sex differences in stroke presentation and prognosis, with women being older and having higher stroke severity scores.
Area of Science:
- Neurology
- Cardiovascular Science
- Epidemiology
Background:
- Sex differences in cardiovascular disease and stroke are a growing area of clinical interest.
- Understanding these disparities is crucial for targeted prevention and treatment strategies.
Purpose of the Study:
- To investigate sex-based differences in the clinical presentation of stroke.
- To evaluate sex differences in stroke severity and patient outcomes.
- To analyze stroke risk factors and treatment patterns across sexes.
Main Methods:
- A retrospective analysis of stroke admissions (ischemic and hemorrhagic) across five hospitals in Italy between January and December 2011.
- Data collected included patient demographics, stroke severity (NIHSS), functional outcome (mRS), and treatment details.
- Statistical methods were employed to compare outcomes between male and female patients.
Main Results:
- A total of 1272 stroke patients (567 women, 705 men) were analyzed.
- Women were significantly older at stroke onset and presented with higher stroke severity scores (NIHSS) compared to men.
- Female sex was associated with worse functional prognosis (mRS≥3) and higher in-hospital mortality, though not statistically significant. Atrial fibrillation was more prevalent in women.
Conclusions:
- Stroke is more severe and associated with worse functional outcomes in women compared to men.
- Older age and higher stroke severity are key factors contributing to poorer outcomes in female stroke patients.
- The findings underscore the need for sex-specific approaches in stroke care and research.
Background And Purpose:
Sex related differences in cardiovascular disease and stroke are issues of increasing interest. The aim of this study was to evaluate for sex differences in clinical presentation, severity of stroke and outcome in a population of patients admitted to 4 public and 1 private hospitals in three different regions of Italy.
Methods:
All hospital admissions for ischemic and haemorrhagic stroke (ICD-IX code 434 and 431 respectively) between January 1st and December 31st, 2011 at five different hospitals located in three different regions of Italy: Milan (North), Rome and Perugia (Center), and Palermo (South) have been recorded and sex-differences have been evaluated.
Results:
A total of 1272 stroke patients were included in the analysis: 1152 ischemic and 120 haemorrhagic strokes, 567 women and 705 men. Compared to men, women were significantly older (mean age 75.2 SD 13.7 vs 71.5 SD 12.5 years, P<0.001) and their stroke severities at onset, measured by NIHSS, were also compared to men (10 SD 8 vs 8 SD 7, P<0.001). Female sex was associated with a worse functional prognosis measured by modified Rankin Scale score (mRS≥3), as well as in-hospital mortality, without reaching statistical significance. There were no observed significant differences between sexes regarding the number of patients treated with thrombolytic therapy. Analysis of the distribution of risk factors between sexes showed a prevalence of atrial fibrillation in women (29% vs 21%, P=0.003).
Conclusions:
Both stroke severity and functional outcome were worse in women.
