目的探讨梗死前心绞痛(PA)不同病程时间对ST段抬高心肌梗死(STEMI)近、远期预后的影响并分析预后相关因素。方法随访2001年1月~2006年1月住院的326例首次STEMI患者,随访到300例,根据PA病程时间分为长期(A)、近期(B)、短期(C)3组,比较临床特征及主要不良心脏事件(MACE)发生率。结果①A组总心源性死亡率及远期主要不良心脏事件(MACE)发生率显著高于C组。②COX分析显示首次心肌梗死后未行PCI是STEMI患者死亡的独立预测因素。结论长期心绞痛患者STEMI后远期MACE发生率高于短期心绞痛组;首次心梗后未行PCI是STEMI患者死亡的独立预测因素。
Objective To investigate the effect of different durations of pre-infarction angina (PA) on the short- and long-term prognosis of STEMI and to analyze the prognostic factors. Methods A total of 326 first-episode STEMI patients who were hospitalized from January 2001 to January 2006 were followed up to 300 patients. According to PA duration, they were divided into three groups: long-term (A), short-term (B) And the incidence of major adverse cardiac events (MACE). Results ① The incidence of total cardiac death and long-term major adverse cardiac events (MACE) in group A was significantly higher than that in group C ② COX analysis showed that PCI after the first myocardial infarction was an independent predictor of death in STEMI patients. Conclusions The long-term MACE incidence after long-term angina pectoris is higher than that of short-term angina pectoris group. The absence of PCI after the first myocardial infarction is an independent predictor of death in patients with STEMI.
