Abstract
We determined the incidence, predictors, and outcomes of persistent renal dysfunction (PRD) following percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Among 16 264 patients enrolled in a nationwide registry, we studied patients with AMI who had their estimated glomerular filtration rate at baseline and 1 month later (n = 3606). We used multivariate regression and propensity score (PS)-matched Cox proportional hazards to evaluate the association between PRD and outcomes. Persistent renal dysfunction occurred in 1333 (37%) patients. Significant PRD contributors included old age, low body mass index (BMI), hypertension, Killip class, and the extent of vessel disease. Persistent renal dysfunction was associated with an increased 1-year major adverse cardiac events (all-cause death, myocardial infarction, or revascularization) relative to no-PRD (entire cohort: 6.2% vs 4.5%, hazard ratio[HR] 1.63, 95% confidence interval [CI] 1.18-2.25, P = .003; PS-matched cohort: 7.2% vs 4.9%, HR 1.67, 95% CI 1.08-2.58, P = .022). In conclusion, PRD occurred in approximately one-third of patients with AMI following PCI. It was associated with old age, hypertension, low BMI, initial hemodynamic instability, and extent of vessel disease and was a predictor of worse outcomes at 1 year.
