摘　　要：【目的】评价彩色多普勒超声心动图在急性心肌梗死及其并发症诊断中的应用价值?【方法】 分析本院120例住院急性心肌梗死患者的临床及超声心动图资料?【结果】 超声心动图检出心肌梗死112例,并发症27例(室壁瘤10例,左室附壁血栓2例,室间隔穿孔2例,中?重度二尖瓣返流13例);超声心动图与心电图对广泛前壁和前壁心肌梗死部位及范围的估测高度一致;超声心动图估测心肌梗死部位与冠状动脉造影所示病变血管供血区域基本相符;非单一部位心肌梗死时,超声心动图较易漏诊下壁或右室梗死?【结论】超声心动图是检测急性心肌梗死敏感而准确的方法,可与心电图相互印证?相互补充;超声心动图是检出室壁瘤?左室附壁血栓?室间隔穿孔及二尖瓣返流等并发症的首选方法;对于疑诊急性心肌梗死患者,检查中应特别注意并存下壁或右室梗死的可能性?Objective To assess the usefulness of color Doppler echocardiography in the diagnosis of acute myocardial infarction and its complications. Methods To analyze the clinical data of 120 patients who were admitted to our hospital and examined using echocardiography with-in two weeks of the onset of acute myocardial infarction. Results 112 patients with acute myocar-dial infarction and 27 cases of its complications were detected by echocardiography; the location and size of myocardial infarction estimated by echocardiography and electrocardiography were consis-tent; the location of myocardial infarction estimated by echocardiography was in accordance with the area supplied by the culprit artery in coronary angiography; inferior wall or right ventricular infarction was more easily missed by echocardiography when the infarct involved more than one area. Conclusions Echocardiography is a sensitive and accurate method for observing acute myocar-dial infarction. It is the method of choice for detecting ventricular aneurysm, mural thrombi, ven-tricular septal defect and mitral regurgitation. In patients suspected with myocardial infarction, more attention should be paid to the possibility of inferior wall or right ventricular infarction.
