回顾性分析了38名冠心病人五年(1974—1979)病死率与左室收缩间期(STI)的相关。五年内共有8人死亡,其死亡原因经医院或医生诊断为心肌再梗塞,休克或心律失常、猝死。 以STI值超过正常人“均值士2×标准差”为界限,对比了生存与死亡的分布。超过此界限者,五年的累计病死率比低于此界限的要高的多(P<0.05).其中以PEP/LVET一项在区别生存与死亡上最为显著。冠心病人左心功能指标在一定程度上反映了冠脉病变和心肌缺血的严重程度,因而与预后有关。
A retrospective analysis of 38 patients with coronary heart disease five years (1974-1979) mortality and left ventricular systolic interval (STI) correlation. A total of eight people died within five years, the cause of death by hospital or doctor diagnosed myocardial re-infarction, shock or arrhythmia, sudden death. To STI value exceeds the normal “mean ± 2 standard deviation” as the limit, compared the distribution of survival and death. Over this limit, the five-year cumulative fatality rate was much lower than this limit (P <0.05), with PEP / LVET being the most significant difference between survival and death. Left heart function in patients with coronary heart disease to some extent reflect the severity of coronary artery disease and myocardial ischemia, and prognosis.
