摘　　要：目的:应用超声心动图研究缺血性二尖瓣反流(IMR)所致左室、二尖瓣环动力学变化。方法:超声心动图检测86例缺血性二尖瓣反流患者(前壁心肌梗死49例,下壁心肌梗死37例)和30例正常人的心脏,测量左室参数及二尖瓣环形态参数。结果:IMR组左室EDV、ESV增加,LVEF减低,但与对照组无显著差异;二尖瓣环面积及位移与对照组有显著差异;不同部位心肌梗死均发生明显左室重构;下壁梗死组PPM-AMP明显延长。结论:超声心动图作为心肌梗死患者的常规检查,可以针对不同患者进行不同的参数检查,这也为临床医生选择个性化治疗方案和疗效评价提供了依据。Objective： To research the changes of dynamics about the left ventricular and the mitral valve ring which leaded by ischemic mitral regurgitation（IMR） through echocardiography.Methods： Echocardiography performed on 86 cases of IMR（including 49 patients with anterior myocardial infarction and 37 patients whit inferior myocardial infarction） and 30 cases of normal control,to measure parameters of the left ventricular and the mitral valve ring shape.Results： In the group of IMR,the EDV and ESV of left ventricular were increased and the LVEF was reduced,but there was no significant difference in comparing with the control group（P ＆gt; 0.05）.There were significant difference in comparing area and displacement of mitral annular between each group（P ＆lt;0.05）.The left ventricular remodeling occurred significantly in all different parts of the myocardial infarction in the group of IMB.In the inferior wall infarction group,the PPM-AMP was longer significantly.Conclusions： As a routine examination of patients with myocardial infarction,echocardiography can be determined different parameters for different patients.This also provided the basis for the clinician to choose individualized treatment programs and efficacy evaluation.
