Echocardiographic findings in ischemic stroke patients with obstructive sleep apnea.

ABSTRACT:

Background

Obstructive sleep apnea (OSA) has been associated with cardiac abnormalities. Whether any cardiac dysfunction is present in ischemic stroke patients with OSA is not known. The purpose of this study was to compare echocardiographic findings in ischemic stroke patients with and without OSA.

Methods

Nocturnal polysomnography was performed on 28 ischemic stroke subjects within 7 days of symptom onset. OSA was defined as an apnea-hypopnea index of ≥10. Echocardiographic variables were compared between the OSA and non OSA groups using Wilcoxon signed-rank, chi-square, or Fisher's exact tests.

Results

The 14 (50%) subjects with OSA had comparable cardiac function and structure to those without OSA (n=14). Left ventricular (LV) mass index, LV ejection fraction, LV
