左心室室壁运动异常与冠状动脉临界病变中心血管事件的关系

Relationship between left ventricular wall motion abnormalities and cardiovascular events in patients with coronary borderline lesions

目的探讨冠状动脉临界病变患者左心室室壁运动异常与心脏事件的关系。方法 116例经冠状动脉造影证实的除介入干预血管以外的血管或血管段存在冠状动脉临界病变的非ST段抬高急性心肌梗死患者,根据超声心动图检查分为观察组(存在左心室室壁运动异常)56例和对照组(无左心室室壁运动异常)60例,对其进行随访研究,观察2组心血管事件的发生情况。结果观察组心肌梗死的发生率高于对照组,差别有统计学意义(P<0.05);其余心血管事件2组间差别无统计学意义(P>0.05)。结论左心室室壁运动异常是冠状动脉临界病变患者发生心肌梗死的独立危险因素。

Objective To investigate the relationship between left ventricular wall motion abnormalities and cardiovascular events in patients with coronary borderline lesions.Methods One hundred and sixteen non-ST elevation acute myocardial infarction patients were confirmed with coronary borderline lesions in non-intervention vessel by coronary angiography.The patients were divided into observation group（n=56,with left ventricular wall-motion abnormalities） and control group（n=60,without left ventricular wall-motion abnormalities） according to the echocardiography examinations.The cardiovascular events were observed between two groups.Results The incidence of myocardial infarction in observation group was significantly higher than that in control group（P0.05）.There were no significant differences in other cardiovascular events between the two groups（P0.05）.Conclusion The left ventricular wall motion abnormalities is independent risk factor to predict myocardial infarction in patients with coronary borderline lesions.
