Effect of myocardial Scar detected by Cardiac Magnetic Resonance on perfusion time and short term outcomes after Coronary Artery Bypass Graft Surgery.

Methods Patients who underwent LGE CMR between January 2003 and February 2010 <1 month prior to CABG were included. A standard 16 segment model was used for Left ventricular (LV) scar quantification. Patients were categorized into Scar group and No-scar groups. Perfusion time (PT), Cross clamp time (CCT), 30-Day mortality, Ventricular arrhythmia, duration of ventilation, prolonged ICU (ICU-LOS) and hospital stay (H-LOS) were obtained. Chi square test, ttest, Wilcoxon rank sum tests and multivariate regression analysis was used for data analysis.
