Abstract 108: Contemporary Timing and Etiology of Mortality in ST-Elevation Myocardial Infarction

Background: Acute treatment of ST-elevation myocardial infarction (STEMI) has focused on early reperfusion, prompt defibrillation, and appropriate mechanical support to mitigate short-term mortality. Long-term patterns of death in a contemporary population are not well described. Methods: We reviewed consecutive cases of STEMI treated with percutaneous coronary intervention (PCI) at our center between January 1, 2011, and December 31, 2016, and divided patients into two groups: uncomplicated STEMI (US) and complicated STEMI (CS). CS was defined by presence of cardiac arrest or cardiogenic shock, ascertained from first-medical-contact to device time for PCI. We assessed for differences in characteristics and short- and long-term mortality between the groups. Results: We identified 1,272 patients with STEMI; 214 of which were CS (16.8%). Those with CS were significantly more likely to have heart failure (22.9% vs 11.3%, p Conclusion: Despite advances in the in-hospital care of patients with STEMI, there remains a significant risk of long-term mortality for both patients with uncomplicated and complicated STEMI. A substantial proportion of overall STEMI mortality now occurs after hospital discharge predominantly due to non-cardiovascular causes. Systems of care to mitigate this long-term risk are needed.
