目的 :探讨急性心肌梗死伴心功能KillipⅡ～Ⅲ级患者 3 0天内行经皮冠状动脉介入治疗 (PCI)对预后的影响。方法 :168例急性心肌梗死患者根据心功能Killip分级分为心功能KillipⅠ级组 91例 ,其中接受PCI治疗 3 8例 ;心功能KillipⅡ～Ⅲ级组 77例 ,其中接受PCI治疗 44例。分别比较第 1个月、第 2～ 12个月患者死亡率。结果 :在心功能KillipⅡ～Ⅲ级组中 ,接受PCI治疗患者第 1个月、第 2～ 12个月死亡率较非PCI治疗患者明显下降 ( 6 8%vs.18 2 %、9 1%vs.12 1% ) ,均有显著性差异 (P <0 0 5～ 0 0 1)。心功能KillipⅠ级组中 ,接受PCI治疗患者第 1个月死亡率较非PCI治疗患者下降 ( 2 6%vs .5 7% ) ,有显著性差异 (P <0 0 5 ) ,但第 2～ 12个月死亡率较非PCI治疗患者无显著差别。结论 :急性心肌梗死伴心功能KillipⅡ～Ⅲ级患者 1个月内行PCI治疗能减少死亡率 ,改善预后
Objective: To investigate the effect of percutaneous coronary intervention (PCI) on the prognosis of acute myocardial infarction with cardiac function KillipⅡ ~ Ⅲ patients within 30 days. Methods: A total of 168 acute myocardial infarction patients were divided into three groups: Killip Ⅰ group (91 cases) and PCI group (38 cases). Cardiac function Killip Ⅱ ~ Ⅲ group (77 cases) received PCI in 44 cases. Patients were compared for the first month, 2 to 12 months mortality. Results: In the Killip class Ⅱ ~ Ⅲ group, the mortality rate in the first month, the second to the twelfth month after PCI was significantly lower than that in the non - PCI patients (68% vs.18%, 91% vs. 12 1%), there was a significant difference (P <0 0 5 ~ 0 0 1). In the Killip class I group, the first month mortality rate in PCI patients was significantly lower than that in non-PCI patients (26% vs. 57%) (P <0.05) The 12-month mortality rate was not significantly different from the non-PCI patients. Conclusion: PCI within one month after acute myocardial infarction with cardiac function Killip Ⅱ ~ Ⅲ patients can reduce mortality and improve prognosis
