收缩时间间期(STI)作为一项无创性检查方法,对于了解冠心病、心绞痛和心肌梗塞后病人的左心功能,劳动力鉴定及预后等有一定价值。本文对临床确诊为心肌梗塞的120例患者作了STI检查,其中40例同时作了同位素核听诊器检查;并选取85例正常人作对照,目的在于了解心肌梗塞后病人的左心功能状态。 资料与方法 一、临床资料: 1.性别与年龄:心肌梗塞组120例,男97例,女23例;年龄41～76岁,平均55.7±8.5岁;其中急性(AMI)28例,陈旧性(OMI)92例。正常组
As a noninvasive method, the systolic time interval (STI) is of value in understanding left ventricular function, labor appraisal and prognosis in patients with coronary heart disease, angina pectoris and myocardial infarction. In this paper, 120 patients with clinically diagnosed myocardial infarction were examined by STI, of which 40 were examined by isotope nuclear stethoscope at the same time. 85 healthy individuals were selected as controls to understand the left ventricular functional status of patients after myocardial infarction. Materials and Methods First, the clinical data: 1 gender and age: 120 cases of myocardial infarction group, 97 males and 23 females; aged 41 to 76 years, mean 55.7 ± 8.5 years; of which 28 cases of acute (AMI), old (OMI) 92 cases. normal group
