Values are % or mean ± SD. Baseline characteristics, comorbidities, admission data, and laboratory studies, stratified by Hospital risk Quintile.
CHF = congestive heart failure; ESRD (HD) = end-stage renal disease (hemodialysis); GFR (CG) = glomerular filtration rate (Cockcroft-Gault); IDDM = insulin-dependent diabetes mellitus; LVEF = left-ventricular ejection fraction; MI = myocardial infarction; NYHA = New York Heart Association functional class; PAD = peripheral artery disease; PCI = percutaneous coronary intervention; Prox. LAD = proximal left anterior descending coronary artery; STEMI = ST-segment elevation myocardial infarction.
