Nationwide trends and outcomes of percutaneous coronary intervention for stable ischemic heart disease in end-stage kidney disease: a longitudinal study

Patients with end-stage kidney disease (ESKD) are at high risk for coronary artery disease. We investigate the trends and outcomes of percutaneous coronary intervention (PCI) for stable ischemic heart disease (SIHD) in patients with ESKD. We utilized the United States Renal Data System [2010-2018] to include adult patients with ESKD on dialysis for at least 3 months who underwent PCI for SIHD. Patients with myocardial infarction during index hospitalization, history of coronary artery bypass graft or renal transplantation and without Medicare AB coverage were excluded. Trends and related outcomes, including mortality and revascularization rate, were studied. The mean age was 65.1 years with 57.5% male and a majority White (64.5%). The dialysis duration was ≤5 years in 83.3% patients. Hypertension (97.6%) and diabetes mellitus (76.8%) were the most common comorbidities. PCI procedures per 1,000 ESKD patients dropped from 6.2 in 2010 to 2.6 in 2018 (P
