Abstract
Abstract
Background
The efficacy of intra-aortic balloon pump (IABP) has been proven in high-risk patients undergoing coronary artery bypass grafting (CABG). However, data on the timing and benefits of IABP support in diffuse coronary artery disease after CABG combined with coronary endarterectomy (CE) remain scarce. This retrospective study assessed the effect of intraoperative or postoperative IABP on 30-day outcomes of off-pump CABG+CE.
Methods
From January 2012 to December 2018, 546 patients undergone off-pump CABG+CE were divided into control group (n = 437) and IABP group (n = 109). Risk factors for 30-day outcomes were evaluated. Subgroup analysis from IABP group was conducted to identify the effect of timing IABP on 30-day outcomes.
Results
CE on left anterior descending branch of coronary artery (LAD) (OR = 3.079, 95% CI 1.077–8.805, P = 0.036), CE with≥2 vessels (OR = 9.123, 95% CI 3.179–26.033, P < 0.001) and length of atherosclerotic plaque ≥3 cm (OR = 16.017, 95% CI 5.941–43.183, P < 0.001) were independent risk factors for postoperative acute myocardial infarction (AMI) and 30-day mortality. Comparing with intraoperative IABP support, postoperative IABP support (OR = 3.987, 95% CI1.194–13.317, P = 0.025) was closely associated with postoperative AMI and 30-day mortality.
Conclusions
For patients undergone off-pump CABG and extensive CE (CE on LAD, CE ≥2 vessels and length of atherosclerotic plaque ≥3 cm), intraoperative IABP support may improve 30-day outcomes.
