ABSTRACT
Objective To evaluate the outcome of patients using intra-aortic balloon pump IABP undergoing coronary artery bypass grafting and to assess the results.Methods From December 2001 to December 2011,eighty-two consecutive patients,who used IABP undergoing coronary artery bypass grafting were studied.The out-come of early complication,mortality,LVEF were analyzed.Results Fourteen patients died.Forty-three patients,who used IABP,no serious complications (malignant arrhythmia,renal insufficience),preoperative LVEF was (46.0 ± 1.8) ％,LVEDD was (66.0 ± 4.1) mm,early postoperative LVEF was (50.0 ± 2.7) ％,LVEDD was (53.0 ± 2.8) mm (P ＜ 0.05).Conclusion Use of IABP decreased early mortality,and postopertive respiratory tract infections,renal insufficiency were the main complication.Positive use of IABP postoperatively can decrease early mortality.
ABSTRACT
Objective To evaluate the outcome of patients with low ejection fraction undergoing coronary artery bypass grafting.Methods One hundred and twenty-eight consecutive patients with left ventricular ejection fraction (LVEF) ≤35％,who underwent Off-pump caronary bypass surgery or Cardiopulmonary coronary artery bypass between December 2000 and Novomber 2010 were studied.The outcome of early complication,mortality,LVEF were analyzed.Results LVEF and LVEDD were significantly increased in early postoperation (P ＜ 0.05 ).Use of Intra-aotric balloon counterpulsation(IABP) can decrease early mortality,and postopertive respiratory tract infections,renal insufficiency were found to be the main complications.Conclusions Preoperative low ejection fraction has no relationship with postoperative early mortality.using medicine to adjust heart function,strcity control blood pressure,blood glucose,heart rate preoperation,positive use of IABP postoperativon are key point to decrease early mortality.
