急性脑梗死患者左室功能与颈动脉粥样硬化的关系

Correlation between left ventricular function and carotid artery in acute cerebral infraction patients

目的探讨急性脑梗死(ACI)患者左室功能与颈动脉粥样硬化的关系。方法选择ACI患者100例(AC I组),短暂性脑缺血发作或后循环缺血患者100例(对照组)。采用超声诊断仪检测两组心功能指标及颈动脉内膜—中层厚度(IMT),并行心电图检查。结果与对照组比较,ACI组心电图异常率升高,二尖瓣舒张早期血流速度/舒张晚期血流速度降低,IMT增加(P<0.05或<0.01)。结论 ACI可影响左室收缩及舒张功能,颈动脉粥样硬化程度与AC I患者的左室舒张功能降低有相关性。

Objective To investigate the relatiaonship of left ventricular fuction and carotid artery in acute infarction patients（ACI）.Methods One hundred ACI patients（ACI group） and transient ischemic attack or posterior circulation ischemia without neurological function defect patients（control group） were recruited.Carotid intima-media thickness（IMT） and ventricular function indicator in two group were detected by color doppler ultrasonography,and then having an electro-cardiogram.Results Compared with control group,abnormal rate of ECG was increased,ratio of early diastolic inflow speed and lately diastolic inflow speed of mitral valve decreased,IMT thick in ACI group（P0.05 or 0.01）.Conclusions ACI can influence left ventricular systolic and diastolic function.There is a positive correlation between carotid atherosclerosis degree and ACI left ventricular diastolic function.
