Abstract:
Objective: To evaluate short-term effect and risk factors for the timing of intra-aortic balloon pump (IABP) implantation with coronary artery bypass grafting (CABG) in high risk coronary artery disease (CAD) patients. Methods: A total of 197 high risk CAD patients received IABP with CABG in our hospital from 2010-01 to 2015-12 were retrospectively analyzed. There were 91 (46.2%) male and the mean arterial pressure (MAP) was (70.3±8.2) mmHg. Based on IABP implantation time, the patients were divided into 2groups: Pre-operative IABP group,n=89 and Intra- , post-operative IABP group,n=108. Peri-operative condition, durations of mechanical ventilation and ICU stay were compared between 2 groups; survival condition was studied by Kaplan-Meier analysis; risk factors causing 30-day mortality was assessed by Logistic regression analysis and its sensitivity and specialty was measured by ROC curve. Results: The mean durations for aortic clamping and cardiopulmonary bypass were (86.7±37.3) min and (147.3±18.4) min in all 197 patients. The age, gender, blood levels of CK-MB c-TnI, creatinine, MAP and European cardiac surgery system scoring were similar between 2 groups, allP>0.05. Compared with Intra- , post-operative IABP group, Pre-operative IABP group had decreased CK-MB (130.6±25.4) mmol/L vs (149.7±18.2) mmol/L at 48h post-operation and mechanical ventilation time (81.5±10.3) h vs (107.9±11.5) h, less in-hospital stay (21.3±4.1) d vs (27.7±9.4) d, reduced acute kidney injury (3.4% vs 23.1%), brain complication (5.6% vs 19.4%) and 30-day mortality (4.5% vs 36.1%), allP<0.05. Kaplan-Meier analysis indicated that the median survival time was longer in Pre-operative IABP group, (27.9±1.2 vs 16.5±2.2) dP<0.05; Logistic regression analysis and ROC curve demonstrated that IABP re-implantation (OR=2.37, 95% CI 1.42-5.72,P=0.01) was an important risk factor for 30-day mortality with the sensitivity of 75.3% and specialty of 67.4%. Conclusion: Pre-operative IABP implantation was helpful for decreasing post-operative level of CK-MB, reducing mechanical ventilation, in-hospital time and short-term mortality in high risk CAD patients; IABP re-implantation was the risk factor for short-term mortality.
