本研究估价短暂、孤立。倒置T波对拟诊急性心肌梗塞(AMI)的大组病例及对照组的诊断及予后意义。方法:研究组127例,男74(平均年龄63岁),女53(平均年龄64岁)、均符合下列标准:(1)胸痛增剧;(2)对称性孤立。倒置T波>0.1毫伏;(3)ST和QRS无改变。对照组84例,男53(平均年龄60岁),女31(平均年龄66岁)。对照组与研究组同期入院,无AMI及T波改变。年龄、性别及危险因素均与研究组配对。随访12-48个月。追综ECG及血清CK-MB改变。结果:随访期间,研究组与对照组分别有22例(17%)和7例(8%)患AMI(P<0.02);30例(24%)和10例(12%)死亡(P<0.01)。研究组39例(31%)。对照组16例(19%)死亡或患AMI(P<0.01)。
The study is assessed briefly and isolated. Inverted T-wave diagnosis of acute myocardial infarction (AMI) in patients with large groups and control group and post-diagnosis significance. Methods: The study group of 127 cases, male 74 (mean age 63 years), female 53 (average age 64 years), all meet the following criteria: (1) increased chest pain; (2) symmetrical isolation. Inverted T wave> 0.1 mV; (3) ST and QRS were unchanged. The control group of 84 patients, 53 male (average age 60 years), female 31 (average age 66 years). The control group and study group were hospitalized in the same period, no AMI and T wave changes. Age, gender and risk factors were matched with the study group. Follow-up 12-48 months. Follow-up ECG and serum CK-MB changes. RESULTS: During follow-up, 22 (17%) and 7 (8%) patients had AMI (P <0.02) in the study and control groups respectively; 30 (24%) and 10 (12% 0.01). Study group 39 cases (31%). Control group, 16 patients (19%) died or had AMI (P <0.01).
