Abstract:
There is no consensus as to which acute myocardial infarction subtype poses a greater risk after coronary artery bypass grafting (CABG). We compared the early and the long term results of off-pump coronary artery bypass grafting (OPCAB) between patients with STEMI (group I, n = 83), and NSTEMI (group II, n = 237). Group I had higher EuroSCORE, prevalence of emergency surgery, preoperative intra-aortic balloon pump use, preoperative emergency percutaneous transluminal coronary angioplasty, and preoperative thrombolytic use than group II. There were no significant differences in 30-day mortality and major adverse cardiac and cerebrovascular event (MACCE) between groups. Overall 8-yr survival was 93% and 87% in groups I and II, respectively. Freedom from MACCE after 8 yr was 92% and 93% in groups I and II, respectively. After propensity score matching analysis, there were no significant differences in preoperative parameters, postoperative in-hospital outcomes, and long-term clinical outcomes. Surgical results of OPCAB in patients with acute myocardial infarction show good results in terms of long-term survival and freedom from MACCE, with no significant differences in clinical outcomes between STEMI and NSTEMI groups.
