Abstract

Chronic kidney disease (CKD) is an important risk factor for coronary artery disease, yet patients with CKD are less likely to undergo coronary angiography and percutaneous coronary intervention (PCI). We retrospectively analyzed the 2006-2012 National Inpatient Sample Database to examine the temporal trends in coronary angiography and PCI among patients without CKD, with advanced CKD (CKD III-V), and with end-stage renal disease (ESRD) presenting with unstable angina/non-ST elevation myocardial infarction (NSTE-ACS) and ST-elevation myocardial infarction (STEMI). A total of 579,747 admissions for NSTE-ACS and 293,950 admissions for STEMI were studied. Patients with NSTE-ACS were less likely to undergo coronary angiography/PCI than those with STEMI, irrespective of CKD. Between 2006 and 2012, performance of PCI saw an uptrend across all CKD groups with NSTE-ACS (no CKD, 29.9%-36.8%; CKD III-V, 18.2%-21.5%; ESRD, 19.8%-27.5%; all Ptrends < 0.01) and STEMI (no CKD, 57.0%-76.0%; CKD III-V, 33.0%-52.6%; ESRD, 29.9%-42.9%; Ptrends < 0.01). Multivariate analyses revealed that PCI was associated with a lower risk of hospital mortality across all degrees of CKD in both NSTE-ACS (adjusted odds ratios: no CKD, 0.44; CKD III-V, 0.48; ESRD, 0.46; P < 0.01) and STEMI (no CKD, 0.35; CKD III-V, 0.50; ESRD, 0.52; P < 0.01). Performance of PCI increased over time among patients presenting with NSTE-ACS and STEMI in the presence of advanced CKD and independently predicted lower in-hospital mortality
