ABSTRACT
The outcomes of patients with previous coronary bypass graft surgery (CABG) presenting with ST-segment elevation acute myocardial infarction (STEMI) have received limited study. We compared the clinical and procedural characteristics and outcomes of STEMI patients with and without previous CABG in a contemporary multicenter STEMI registry between 2003 and 2020. The primary outcomes of the study were mortality and major cardiac adverse events (MACE death, MI or stroke). Survival curves were derived using the Kaplan-Meier method and compared with the log-rank test. Of the 13,893 patients included in the analyses, 7.2% had previous CABG. Mean age was 62.4 ± 13.6 years, most patients (71%) were men and 22% had diabetes. Previous CABG patients were older (69.0 ± 11.7 vs 61.9 ± 13.6 years, p <0.001) and more likely to have diabetes (40% vs 21%, p <0.001) compared with patients without previous CABG. Previous CABG patients had higher mortality and MACE at 5 years (p <0.001). Outcomes were similar with saphenous vein graft vs native coronary culprits. Previous CABG remained associated with mortality from discharge to 18 months (p = 0.044) and from 18 months to 5 years (p <0.001) after adjusting for baseline characteristics. Long term outcomes after STEMI were worse among patients with previous CABG compared with patients without previous CABG, even after adjustment for baseline characteristics.
