心肌梗塞后心绞痛(PIA)是心肌梗塞的一种特殊类型,其近期死亡率可达17％～50％。本文回顾性分析49例急性心肌梗塞(AMI)病例,以探讨心肌梗塞后心绞痛(PIA)的发生机理、促发因素和预后。 1 临床资料 49例AMI病人均符合1979年WHO诊断标准。AMI后常规心电图监测1周,此后若必要随时予以监测。每次PIA发作均观察血压、心率及心电图变化;疼痛时间>30分钟者及时复查心肌酶。若4周内心肌酶等再次升高,症状和心电图符合AMI诊断标准者定为早期再梗塞。
Post-myocardial infarction (PIA) is a special type of myocardial infarction with a recent mortality rate of 17% to 50%. In this paper, 49 cases of acute myocardial infarction (AMI) were retrospectively analyzed to investigate the pathogenesis, predisposing factors and prognosis of post-myocardial infarction angina pectoris (PIA). 1 Clinical data 49 cases of AMI patients are in line with the 1979 WHO diagnostic criteria. After AMI routine ECG monitoring for 1 week, then if necessary, be monitored at any time. Each PIA attack were observed blood pressure, heart rate and ECG changes; pain time> 30 minutes were promptly reviewed myocardial enzymes. If within 4 weeks again elevated myocardial enzymes, symptoms and ECG in line with AMI diagnostic criteria for early re-infarction.
