Influence of chronic ethanol consumption on the neurological severity in patients with acute cerebral ischemia

Abstract

BACKGROUND AND PURPOSE-: We tested the hypothesis that excessive chronic ethanol consumption is associated with more severe ischemic strokes. METHODS-: We recruited patients with supratentorial cerebral ischemia within 48 hours of symptom onset. We defined heavy drinkers by a weekly consumption of ethanol of ≥300 g and severe strokes by a National Institutes of Health Stroke Scale score≥6. RESULTS-: Of 436 patients, 60 were heavy drinkers. Being a heavy drinker was independently associated with baseline National Institutes of Health Stroke Scale scores ≥6 (odds ratio, 2.35; 95% confidence interval, 1.12-5.26; P=0.023) at the logistic regression analysis. This result was not modified with the propensity analysis. CONCLUSION-: An excessive chronic ethanol consumption is associated with higher baseline stroke severity. © 2013 American Heart Association, Inc.
