Categorical variables are described as absolute numbers (%) and compared by means of the chi-square test; continuous variables are described as mean ± SD and compared by means of the Student’s -test. MI: myocardial infarction; PCI: percutaneous coronary intervention; CrCL: creatinine clearance; CHF: congestive heart failure; CVD: cardiovascular disease. LM: left main coronary artery; LAD: left anterior descending coronary artery; LCA: left circumflex artery; RCA: right coronary artery; TIMI: thrombolysis in myocardial infarction; PCI: percutaneous coronary intervention; IABP: intra-aortic balloon pump; GPI: glycoprotein IIb/IIIa inhibitors; LVEF: left ventricular ejection fraction.
