[摘要] 目的：探讨急性脑梗死患者对左心室功能改变的关系，以及与病变部位、病灶大小及颈动脉硬化的关系。方法：选择100例急性脑梗死患者(ACI组)和100例短暂性脑缺血发作或后循环缺血患者(对照组)。采用彩色多普勒超声诊断仪，检测左心室结构和功能及颈动脉斑块，经统计学处理，进行相关性分析。结果：ACI组二尖瓣舒张早期血流速度/舒张晚期血流速度(0.82±0.31)低于对照组(1.05±0.44)，两组比较差异统计学意义(t=3.525，P<0.05)，不同部位、不同大小脑梗死左心室射血分数和E峰/A峰比值差异无统计学意义。ACI组颈动脉闭塞比例(4%)高于对照组(0)，两组差异有统计学意义(χ2=5.627，P<0.05)。脑梗死组颈动脉斑块、狭窄比例与对照组比较差异无统计学意义(P>0.05)。结论：急性脑梗死可引起左心室功能改变，对舒张功能影响更明显，颈动脉狭窄与脑梗死密切相关，脑梗死不同病变部位、病灶大小对左心室功能没有影响。

[Abstract] Objective: To investigate the changes on left ventricular function in the patients with acute cerebral infarction and the relationship between the location the size and carotid atherosclerosis. Methods: 100 patients with acute cerebral infarction (ACI group) and transient ischemic attack or 100 cases of posterior circulation ischemia (control group) were selected. Color Doppler ultrasonography was used. The left ventricle structure and function and carotid plaque were detected. To take statistical analysis and correlation analysis. Results: Cerebral infarction early diastolic mitril flow velocity/later diastolic flow velocity (0.82±0.31) was lower than the control group (1.05±0.44), there was a significant difference in the two groups (t=3.525, P<0.05). Different parts and different size infarction left ventricular ejection fraction and the size of the peak E/A peak ratio was no statistically different. The proportion of carotid artery occlusion with cerebral infarction (4%) was higher than that of the control group (0) (χ2=5.627, P<0.05). Two groups with atherosclerotic plaque and arterial stenosis was no significant difference (P>0 ......
