P1762Prognostic significance of in-hospital incomplete and terminated revascularization in patients with acute myocardial infarction and without reduced left ventricle ejection fraction

Abstract Introduction In-hospital incomplete and terminated at discharge myocardial revascularization has significant impact on mortality after acute myocardial infarction (AMI), also in patients (pts) with reduced left ventricle ejection fraction (LVEF) ≤35%. However, subjects with LVEF &gt;35%, who are not candidates for implantable cardioverter defibrillators, are still at risk. Authors hypothesized, that in those pts, the prognosis could be related to completeness of revascularization. Purpose To evaluate the risk of death and major adverse cardiovascular events (MACE) among pts with AMI and LVEF&gt;35% in relation to myocardial revascularization status. Methods Single center prospective study encompassed 445-pts with AMI and LVEF&gt;35%, who were treated with percutaneous coronary intervention and who survived in-hospital period. Study population was divided into two groups: group 1. – 73-pts with in-hospital incomplete and terminated revascularization at discharge; group 2. – 372-pts with complete or incomplete revascularization, in whom scheduled procedures were planned and performed (either percutaneous or surgical). The incidence of death and MACE was compared between groups during mean follow-up of 47.5 months after AMI. MACE was defined as a composite of death, recurrent AMI, non-scheduled revascularization, acute heart failure, stroke. Independent predictors for death were identified with multivariate Cox-regression models and expressed as hazard ratio (HR) with 95% confidence interval (CI). Results Patients in group 1. had higher mortality rate than in group 2. (26.4% vs. 9.1%; p&lt;0.001) – figure 1. The difference in the incidence of MACE was higher in group 1. than in group 2. (59.7% vs. 28.2%; p&lt;0.001). The analysis of particular MACE showed, that in group 1. the incidence of recurrent AMI, non-scheduled revascularization and stroke was higher than in group 2. (17.8% vs. 8.9%; p=0.022, and 33.3% vs. 16.1%; p=0.001, and 6.8% vs. 2.4%; p=0.048, respectively). Independent risk factors for death were: age ≥65 years (HR: 4.2; CI: 2.1–8.0) and incomplete and terminated myocardial revascularization at hospital discharge (HR: 2.5; CI: 1.4–4.4). Conclusions After invasive treatment of AMI, the prognosis in patients with LVEF&gt;35% is related to revascularization status. In-hospital incomplete and terminated revascularization at discharge is an independent risk factor for death in this population. </jats:sec
