Summary
Higher serum cholesterol levels predict better outcomes in the first month after acute ischemic stroke. Patients with high cholesterol experienced significantly lower risks of death and poor functional outcomes.
Area of Science:
- Neurology
- Cardiovascular Science
- Epidemiology
Background:
- Cholesterol's link to cerebrovascular disorders is known.
- Early outcome prediction after ischemic stroke remains critical.
- The prognostic role of cholesterol in acute ischemic stroke is understudied.
Purpose of the Study:
- To determine if serum cholesterol levels predict outcomes in the first month post-ischemic stroke.
- To investigate the prognostic value of cholesterol in acute ischemic stroke patients.
Main Methods:
- Analysis of data from 3,273 first-ever ischemic stroke patients.
- Comparison of functional outcomes at 1 month between high (cholesterol > 6.5 mmol/L) and normal cholesterol groups.
- Univariate and multivariate statistical analyses were employed.
Main Results:
- High cholesterol patients had a 2.2-fold lower risk of death (p=0.002).
- High cholesterol patients showed a 2.1-fold lower risk of poor functional outcome (p<0.001).
- Higher cholesterol levels independently predicted better functional outcomes (OR 0.48, p<0.001).
Conclusions:
- Elevated serum cholesterol is associated with improved early outcomes after ischemic stroke.
- Higher cholesterol levels may indicate a better prognosis in the acute phase of ischemic stroke.
