Abstract:
This study aimed to evaluate the effects of percutaneous coronary intervention (PCI) on short- and long-term major adverse cardiac events (MACE) in elderly (>75 yr old) acute myocardial infarction (AMI) patients with renal dysfunction. As part of Korea AMI Registry (KAMIR), elderly patients with AMI and renal dysfunction (GFR<60 mL/min) received either medical (n=439) or PCI (n=1,019) therapy. Primary end point was in-hospital death. Secondary end point was MACE during a 1 month and 1 yr follow-up. PCI group showed a significantly lower incidence of in-hospital death (20.0% vs 14.3%, P=0.006). Short-term and long-term MACE rates were higher in medical therapy group (31.9% vs 19.0%; 57.7% vs 31.3%, P<0.001), and this difference was mainly attributed to cardiac death (29.3% vs 17.6%; 51.9% vs 25.0%, P<0.001). MACE-free survival time after adjustment was also higher in PCI group on short-term (hazard ratio, 0.67; confidence interval, 0.45-0.98; P=0.037) and long-term follow-up (hazard ratio, 0.61, confidence interval, 0.45-0.83; P=0.002). In elderly AMI patients with renal dysfunction, PCI therapy yields favorable in-hospital and short-term and long-term MACE-free survival.
