Abstract:
BACKGROUND AND OBJECTIVES: Renal insufficiency (RI) has been reported to be associated with unfavorable clinical outcomes in patients undergoing percutaneous coronary interventions (PCI). However, little data is available regarding the impact of moderate to severe RI on clinical outcomes in patients with acute myocardial infarction (AMI) undergoing PCI. SUBJECTS AND METHODS: Between March 2003 and July 2007, 878 patients with AMI who underwent PCI were enrolled. Based on estimated glomerular filtration rate (eGFR) using the Modification of Diet in Renal Disease (MDRD) equation, patients were divided into two groups: eGFR <60 mL/min.m2 (moderate to severe RI, group A) and eGFR > or =60 mL/min.m2 (normal to mild RI, group B). The primary endpoint was all-cause mortality at 1-year after successful PCI. The secondary endpoints were non-fatal myocardial infarction (MI), target lesion revascularization (TLR), target vessel revascularization (TVR), stent thrombosis (ST) and major adverse cardiac events (MACE) at 1-year. RESULTS: In group A, patients were more often male and older, with diabetes and hypertension. Compared to patients in group B, group A showed significantly higher incidences of all-cause mortality, cardiac mortality, non-fatal MI and MACE. The needs of TLR and TVR, and the incidence of ST were not significantly different between the two groups. Independent predictors of 1-year mortality were eGFR <60 mL/min.m2, male gender, older age and a lower left ventricular ejection fraction. CONCLUSION: In patients with AMI, moderate to severe RI was associated with mortality and MACE at 1-year after successful PCI. In addition, eGFR <60 mL/min.m2 was a strong independent predictor of 1-year mortality.
