Outcome of acute myocardial infarction versus stable coronary artery disease patients treated with coronary bypass surgery

ObjectiveTo study the long-term outcome differences between acute myocardial infarction (MI) and stable coronary artery disease (CAD) patients treated with coronary artery bypass grafting (CABG). MethodsWe studied retrospectively patients with MI (n = 1882) or stable CAD (n = 13117) treated with isolated CABG between 2004 and 2014. Inverse propensity probability weight adjustment for baseline features was used. Median follow-up was 7.9 years. Results In-hospital mortality (8.6% vs. 1.6%; OR 5.94;p Conclusion MI patients have poorer short- and long-term outcomes compared to stable CAD patients after CABG and risk difference continues to increase with time.Key Messages Patients with myocardial infarction have poorer short- and long-term outcomes compared to stable coronary artery disease patients after coronary artery bypass grafting (CABG). Higher risk of death continues also in stabilized first-year myocardial infarct survivors. The importance of efficient secondary prevention and follow-up highlights in post-myocardial infarct population after CABG.
