不明原因缺血性卒中患者左心房超声检查特点

摘要/Abstract

摘要：

【摘要】目的探讨不明原因缺血性卒中患者左心房超声检查特点。方法连续入选我院不明原因缺血性卒中患者36例，选取同期健康志愿者35例作为对照组，两组均行经胸超声心动图检查，比较两组间左心房大小、面积及左心房射血分数、左心房压力等结构及功能指标。结果两组左心房内径、左心房面积均无统计学差异。不明原因缺血性卒中组左心房射血分数低于对照组［（61.13 ±11.42）% vs （65.15 ±10.12）%，P=0.043］；左心房压高于对照组［（98.76± 21.89）mmHg vs （75.37± 26.98）mmHg，P=0.0414］；左心房中部血流流速低于对照组［（57.50 ±4.03）cm/s vs （66.56 ±10.59）cm/s，P=0.035］。结论不明原因缺血性卒中患者存在左心房功能异常。

文章导读： 本研究提示不明原因缺血性卒中患者心脏超声显示其可能存在左心房功能异常。

Abstract:

【Abstract】 Objective To investigate the left atrial (LA) structure and function in stroke of undetermined cause by echocardiography. Methods Thirty-six consecutive patients with stroke of undetermined cause and thirty-five healthy cases were involved. LA size, area, LA ejection fraction and LA pressure were measured and compared between both groups by echocardiography. Results There were no statistical differences in LA diameter and LA size between both groups (P=0.811 and P=0.542, respectively). LA ejection fraction of stroke group was lower than that of the control group ( [61.13 ±11.42]% vs [65.15± 10.12]%, P=0.043). LA pressure in stroke group was higher than that in the control group ([98.76± 21.89]mmHg vs [75.37 ±26.98] mmHg, P=0.0414), while LA central blood flow velocity was lower than that of the control group ([57.50 ±4.03] cm/s vs [66.56± 10.59] cm/s, P=0.035). Conclusion Abnormal function of the left atrium exists in stroke of undetermined cause.
