Abstract
Aim To summarize the results of coronary artery bypass grafting (CABG) for the patients with low left ventricular ejection fraction (LVEF). Methods A retrospective study was carried out. 63 cases with low LVEF (≤0.40) underwent CABG, 45 males and 18 females. Cardiopulmonary bypass (CPB) was applied in CABG. Surgical technique, complications, LVEF, left ventricular end-diastolic diameter (LVEDD), heart function and post-operative treatment were analyzed. Results Early post-operative complication included: Re-open in 1 case (1.6%), LCOS in 5 cases (7.9%), IABP used in 3 cases (4.8%), repeatedly atrial fibrillation in 6 cases (9.5%), complication of CNS in 1 case (1.6%), hepatic dysfunction in 2 cases (3.2%), renal insufficiency in 2 cases (3.2%), respiratory insuffi-ciency in 3 cases (4.8%), pleural effusion in 7 cases (11.1%) and death in 1 case (1.6%). The others had favorable outcomes. There were significant improvement in mean LVEF, LVEDD and NYHA class postoperatively (P<0.01).Conclusions Suitable adaptative disease, excellent surgical technique, advanced myocardial protection, IABP applied early when weanning from pump is difficult and enhancing post-operative treatment can significantly improve the results of CABG for the patients with low LVEF.关键词
