Cardiac Function and Short-Term Outcome in Patients with Acute Ischemic Stroke: A Cross-Sectional Study.

Academic Article

Abstract

  • Few studies have investigated the relationship between left ventricular ejection fraction (LVEF) and functional outcome in ischemic stroke patients. The purpose of this study was to determine if a low LVEF in ischemic stroke was associated with functional outcome. A cross-sectional study was performed on ischemic stroke patients admitted to a single academic stroke center from June 2008 to December 2010. LVEF was determined using transthoracic or transesophageal echocardiography. Patients were categorized into three LVEF groups: severely low (<30%), moderately low (30-49%), and normal (>50%). Baseline demographics, in-hospital complications, and early outcomes were compared among LVEF groups using Chi-square, Wilcoxon rank sum, and logistic regression.590 patients met inclusion criteria (median age 65, 74% African American, 48% female). LVEF was normal in 79.8%, moderately low in 10.8%, and severely low in 9.3%. A smaller proportion of patients with severely low LVEF appeared to have good functional outcome compared to other groups (26% vs. 40% vs. 45%, p=0.028); however, this relationship was not significant after adjusting for age, baseline National Institute of Health Stroke Scale score and admission glucose (OR 0.6, 95% CI 0.3-1.3, p=0.216). Low LVEF was not an independent, significant predictor of short-term functional outcomes in ischemic stroke patients.
