AF: atrial fibrillation; LITA: left internal thoracic artery; ICU: intensive care unit; IABP: intraaortic balloon pump; ARD: acute renal dysfunction. Data were expressed as median (minimum-maximum) for continuous variables or number (%) for categorical variables. Continuous variables were compared using independent samples t-test or Wilcoxon rank sum test. Categorical variables were reported as frequency (percent) and compared using Pearson's χ² test. Bold value indicates statistical significance at the p<0.05 level.
