Identification of candidates for coronary artery bypass grafting admitted with STEMI and Multivessel Disease

Background: The optimal management of patients with multivessel coronary artery disease (MVD) admitted with STEMI is under debate. CABG is rarely performed, even on ideal candidates. A provisional PCI without stent implantation may allow complete surgical revascularization (CSR) in a subset of patient that we sought to identify in this study. Methods: Patients with STEMI from April 2014 to October 2016 were evaluated and those with a TIMI flow <3 in the culprit vessel, and an additional stenosis of >70% in an epicardial vessel or sidebranch >2.5 mm were selected. Epidemiological variables, surgical risk scores and SYNTAX and SYNTAX II scores were analyzed. All the selected patients were discussed in a post hoc heart-team, and predictors of 12-month events were also analyzed. Results: Seventy-two (19.0%) accomplished MVD criteria. Mean SYNTAX was 19 +/- 13 points and SYNTAX II score recommended CABG in 12 patients (16.7%) and heart-team discussion in 60 (83.3%). All patients were discussed in a post hoc heart-team, which concluded that 21 (29.2%) patients could have been good candidates for CSR. After one year follow-up, SYNTAX II PCI > 40 was found to be the sole independent predictor for 12-month events (OR 12.9[2.7-62.1], p = 0.001). Conclusions: MVD and STEMI with a SYNTAX II PCI > 40 should be discussed in an ad-hoc heart team, after a provisional revascularization of the culprit vessel, and should be considered for CSR, especially when the RCA is the culprit artery and there is a complex disease in the left coronary artery.
