二维超声心动图测定左室节段性室壁运动预测急性心肌梗塞远期预后的研究

A Study on the Prognosis in Survivors of Myocardial Infarction by Two-dimensional Echocardiography

应用二维超声心动图评价46例急性心肌梗塞发病3周时的室壁运动,以室壁运动分数指数(WMSI)为预测心肌梗塞远期预后的指标,发现心肌梗塞远期有心功能不全或严重心绞痛等并发症的WMSI显著高于无并发症者,再梗塞和死于心脏并发症的WMSI亦显著高于非再梗和存活者。WMSI≥1.7者可发生心功能不全或严重心绞痛,心功能不全和死亡者的WMSI均≥2。

To determine the prognosis in survivors of AMI, two-dimensional echocardiography was performed in 46 patients who survived for three weeks after AMI. The wall motion scores index (WMSI) was used as a predictive index of late prognosis in survivors of AML 20 patients with complications of congestive heart failure, severe angina, recurrent infarction and death had a significantly higher WMSI than those without complicantions patients. The result showed that the patients with WMSI 1.7 may develop congestive heart failure or severe angina and the patients with congestive heart failure and death had WMSI 2. Two-dimensional echocardiography provides predictive information about late prognosis in survivors of AMI.
