Variables included in the final model were: quintiles one to four, age, gender, history of congestive heart failure, history of prior coronary artery bypass grafting, history of extra-cardiac vascular disease, history of chronic obstructive pulmonary disease, emergency procedure, creatinine ≥1.5 mg/dl, left ventricular ejection fraction 70%), three-vessel disease (>70%), visible thrombus on the initial coronary angiogram, cardiac arrest, acute myocardial infarction (MI), MI within 7 days, cardiogenic shock, ventricular tachycardia or ventricular fibrillation in the setting of acute MI, and unstable angina. C statistic = 0.82. Hosmer-Lemeshow chi-square = 2.9, p = 0.94. CI = confidence interval. Figure Legend:

Predicted and observed major adverse cardiovascular events (MACE) rates are stratified by quartile of risk, with further stratification by quintile of operator volume. Q = quintile (i.e., Q1, Q2, Q3, Q4, and Q5). Figure Legend:
