Analysis of Left Ventricular Funciton Early after Coronary Artery Bypass Grafting(CABG)

Left ventricular(LV) function was analyzed before and early after coronary artery bypass grafting (CABG) in 57 patients with angina pectoris. There were 43 men and 14 women at a mean age of 61.5 years old (ranged from 41 to 79 years old). The average number of grafts was 2.26. LV function was evaluated using LV ejection fraction(EF), LV end-diastolic volume index(EDVI), LV end-systolic volume index(ESVI) and LV end-diastolic pressure(EDP). LVEDP(p =0.0013), LVESVI(p =0.0002) and LVEDVI (p=0.0001) were significantly improved after CABG. LV function seemed to be improved though no significant improvement in LVEF was demonstrated. In addition, patients whose LVEF was less than 50% before operation were divided into two groups
