摘　　要：目的探讨组织谐波超声心动图(THE)在老年人急性心肌梗死诊断中的应用价值。方法对本院136 例经THE检查的老年初发Q波急性心肌梗死患者的临床及超声心动图资料进行分析。结果男95例,女41例,年龄60-89岁,平均(68±7)岁。THE图像满意率92％(125/136)。THE图像满意者中检出急性心肌梗死117例(94％)。 THE与心电图判断心肌梗死的部位及范围基本一致,尤其是对于急性广泛前壁和前壁心肌梗死,两者的判断高度一致。THE所示心肌梗死部位与冠状动脉造影所示梗死相关动脉供血区域符合率93％。结论 THE能够敏感、准确地检出老年急性心肌梗死患者,可作为早期诊断老年人急性心肌梗死的补充手段。Objective To explore the value of tissue harmonic echocardiography （THE） in the diagnosis of acute myocardial infarction in elderly patients. Methods The clinical and echocardiographic data of 136 elderly patients who developed first Q wave acute myocardial infarction were analyzed. They were admitted to this hospital and examined by THE within two weeks of the onset of the disease. Results There were totally 95 men and 41 women aged 60 - 89 （mean 68 ± 7） years. Using THE, the echocardiograms sufficient for analysis were obtained in 92% of the patients. Of the patients with adequate images, 94% were detected to have myocardial infarction. The location and extent of myocardial infarction estimated by THE and electrocardiography were almost coincident, especially for infarction involving anterior wall. The location of myocardial infarction estimated by THE was in accordance with the territory supplied by the culprit artery in coronary angiography （93%）. Conclusions THE is a sensitive and accurate method for detecting acute myocardial infarction in the elderly patients. It may serve as a complementary tool for the early diagnosis of acute myocardial infarction in these patients.
