| 目的探讨非梗死相关动脉(non-IRA)慢性完全闭塞(CTO)合并ST段抬高心肌梗死(STEMI)患者行经皮冠状动脉介入治疗(PCI)术的预后与左心室射血分数(LVEF)之间的关系。 方法选取STEMI患者130例,根据LVEF水平分为LVEF降低组和LVEF保留组；根据是否合并CTO分为CTO亚组和无CTO亚组。随访1年,比较两组患者的全因死亡和主要心血管不良事件(MACE)。 结果与无CTO亚组比较,LVEF降低患者CTO亚组有更高全因死亡率和MACE发生率；而LVEF保留患者CTO亚组与无CTO亚组之间上述指标差异无显著性。在LVEF降低患者中,non-IRA CTO是全因死亡和MACE的独立预测因子。 结论non-IRA CTO是LVEF降低STEMI患者全因死亡和MACE的独立预测因子。 |

| AimTo investigate the relationship between left ventricular ejection fraction (LVEF) and prognosis of percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) and chronic complete occlusion (CTO) of non-infarct-associated artery (non-IRA). MethodsA total of 1 130 STEMI patients were selected and divided into LVEF reduction group and LVEF retention group according to LVEF level. It is divided into CTO subgroup and non-CTO subgroup according to whether CTO. After 1 year of follow-up, all-cause mortality and major adverse cardiovascular events (MACE) were compared between the two groups. ResultsCompared with the non-CTO group, the CTO group of patients with LVEF reduction had a higher incidence of all-cause mortality and MACE. There was no significant difference in the above indexes between the CTO subgroup and the non-CTO subgroup of LVEF retention patients. non-IRA CTO was an independent predictor of all-cause death and MACE in patients with reduced LVEF. ConclusionIn conclusion, non-IRA CTO was an independent predictor of LVEF reduction in all-cause death and MACE in STEMI patients. |
