ACS, acute coronary syndrome; BIMA, bilateral internal mammary arteries; BMI, body mass index; CCB, calcium channel blockers; CKD, chronic kidney disease; COPD, chronic obstructive pulmonary disease; LAD, left anterior descending artery; LIMA, left internal mammary artery; LM, left main coronary artery; LVEDD, left ventricular end diastolic diameter; LVEF, left ventricular ejection fraction; LVESD, left ventricular end systolic diameter; MI, myocardial infarction; NYHA, New York Heart Association; Pro-BNP, pro-B-type natriuretic peptide; PVD, peripheral vascular disease; RA, radial artery; TAR, total arterial revascularization.
Multivariable analysis was conducted again after excluding the variable without astringency (on-pump) from the previous multivariate logistic regression modeling.
