XXXX Classification on Outcomes in Nonemergent Coronary Artery Bypass Grafting.

@entity1 @entity583 @entity712 @entity101
BACKGROUND: Although @entity1 with ST elevation @entity583 (STEMIs) are known to have worse outcomes than @entity1 with non-ST elevation @entity583 (NSTEMIs), such differences are not well described in the subset of @entity1 undergoing coronary artery bypass grafting. The purpose of this study is to compare postoperative outcomes of @entity1 undergoing nonemergent coronary artery bypass grafting within 1 week after an STEMI versus NSTEMI. METHODS: A retrospective study was performed on @entity1 undergoing isolated coronary artery bypass grafting between 1 and 7 days from an MI from 2008 to 2012. Postoperative outcomes, including mortality and composite postoperative morbidity for @entity1 with STEMI versus NSTEMI, were compared within each group. RESULTS: Of the 446 @entity1 undergoing nonemergent isolated coronary artery bypass grafting between 1 and 7 days after an MI, 122 @entity1 (27.3%) had an STEMI. The STEMI cohort was younger with less incidence of @entity101 than the NSTEMI cohort. However, aside from having a lower incidence of @entity712 , STEMI @entity1 had an overall poorer cardiac status than NSTEMI @entity1 . No differences were found in mortality, rates of major complication, length of intensive care unit stay, and length of hospital stay between STEMI and NSTEMI @entity1 . CONCLUSION: Despite differences in preoperative characteristics and pathophysiology of @entity1 undergoing coronary artery bypass grafting between 1 and 7 days after NSTEMI versus STEMI, no difference was found in early surgical outcome. The classification of MI should therefore not influence surgical decision making in such @entity1 .
