目的为探讨心肌梗死有无Q波对近期预后的影响,随诊78例无Q波型心肌梗死(NQMI)和224例Q波型心肌梗死(QMI)患者。方法随诊以死亡为终点或随诊至患病后6个月。结果两组相比:1.院内死亡率分别为2.56%和13%(P<0.01);2.Kaplan-Meier曲线6个月生存率分别为94.9%和81.5%(时距检验P<0.01),6个月无心脏再发缺血事件发生率分别为85.5%和69.1%(时距检验P<0.01)。结论和QMI组相比,NQMI组近期(6个月)预后较好。
Objective To investigate the effect of Q waves on myocardial prognosis in patients with myocardial infarction. Totally 78 patients with Q-wave myocardial infarction (NQMI) and 224 Q-wave myocardial infarction (QMI) were followed up. Methods follow-up to death or follow-up to 6 months after the illness. RESULTS: The in-hospital mortality rates were 2.56% and 13%, respectively (P <0.01). The 6-month survival rates of Kaplan-Meier curves were 94.9% and 81.5%, respectively (P <0.01 for interval test) The incidence of noncardiac ischemic events at 6 months were 85.5% and 69.1% respectively (P <0.01 for interval test). Conclusion Compared with QMI group, NQMI group has a good prognosis (6 months).
