目的:探讨延迟冠状动脉介入治疗(percutaneous coronary intervention,PCI)对急性ST段抬高心肌梗死(ST-segment elevation myocardial infarction,STEMI)患者左室功能的影响。方法:选择308例STEMI患者,98例延迟PCI,58例紧急PCI,82例静脉溶栓,70例药物治疗。观察住院和随访期间左室功能的变化。结果:住院及随访期间延迟组EF均明显高于溶栓组和药物组。延迟组的LVD、LAD及E/A明显低于药物组和溶栓组(P<0.05)。结论:延迟PCI可防止左室扩大,改善左室功能,提高住院期间及随访期间的治疗效果。
Objective: To investigate the effect of delayed percutaneous coronary intervention (PCI) on left ventricular function in patients with acute ST-elevation myocardial infarction (STEMI). Methods: 308 patients with STEMI, 98 patients with delayed PCI, 58 patients with emergency PCI, 82 patients received intravenous thrombolysis and 70 patients received drug treatment. Changes in left ventricular function during hospitalization and follow-up were observed. Results: During hospitalization and follow-up, EF in delayed group was significantly higher than that in thrombolytic group and drug group. Delayed group of LVD, LAD and E / A was significantly lower than the drug group and thrombolytic group (P <0.05). Conclusion: Delayed PCI can prevent left ventricular enlargement, improve left ventricular function and improve the therapeutic effect during hospitalization and follow-up.
