Impact of comorbidities on ischemic stroke outcomes in women
Insights
Prestroke comorbidities, measured by the Charlson Index, significantly impact long-term stroke outcomes in women. Specific conditions like coronary heart disease and diabetes also predict poorer functional recovery after ischemic stroke.
Area of Science:
- Neurology
- Cardiovascular Medicine
- Epidemiology
Background:
- Investigating prestroke comorbidities' impact on ischemic stroke outcomes in women.
- Utilizing the Charlson Index (CI) to quantify comorbidity burden.
Discussion:
- Higher CI scores independently predicted worse modified Rankin Scale (mRS) scores at 90 days post-stroke.
- Coronary artery disease and diabetes mellitus were significant predictors of poor functional outcome when analyzed individually.
Key Insights:
- Comorbidity burden, assessed by the Charlson Index, is a critical independent predictor of long-term functional outcome in women following ischemic stroke.
- Specific comorbidities, namely coronary heart disease and diabetes, are individually associated with poorer functional status at 90 days.
Outlook:
- Further research into targeted interventions for women with high comorbidity burden.
- Exploring the role of specific comorbidities in stroke recovery pathways.
Background And Purpose:
We assessed the association of prestroke comorbidities with long-term stroke outcomes among women with ischemic stroke.
Methods:
Prestroke comorbid conditions in 133 women admitted with acute ischemic stroke were scored with the Charlson Index (CI). We assessed whether the CI and other specific conditions were associated with modified Rankin Score (mRS) at 90 days or more poststroke.
Results:
After adjustment for initial NIHSS and age, higher CI was the sole factor independently associated with poorer 90 day mRS scores. When CI was excluded, coronary disease and diabetes were independently associated with poorer outcome.
Conclusions:
The extent of comorbidities as assessed by the CI is independently associated with 90-day mRS among women with ischemic stroke, but the individual comorbidities of CHD and DM were each associated with functional outcome.
