The benefit of complete revascularization in elderly patients with non-ST elevation myocardial infarction (NSTEMI), and multivessel disease remains debated (MVD). The aim of our study was to determine the current long-term prognostic benefit of complete revascularization in this population. A retrospective cohort study of 1722 consecutive elderly NSTEMI patients was performed. Among the study participants 30.4% (n = 524) were completed revascularizated and in 69.6% (n = 1198) culprit vessel only revascularization was performed. A propensity score analysis was performed and we divided the study population into two groups: complete revascularization (n = 500) and culprit vessel only revascularization (n = 500). The median follow-up was 45.7 months, the all cause mortality (44.5% vs 30.5%, p < 0.001) (HR 0.74 (0.57-0.97); p = 0.035) and cardiovascular mortality (32.6% vs 17.4%, p < 0.001) (HR = 0.67 (0.47-0.94); p = 0.021) were significantly lower in patients with complete revascularization. In our study, we observed a long-term benefit of complete revascularization in elderly NSTEMI and MVD patients. Elderly patients should also be managed according to current guidelines to improve their long-term prognosis.

Background: Recent studies suggest that the benefit of mineralocorticoid receptor antagonists in the acute coronary syndrome setting is controversial. The aim of this study was to examine the current long-term prognostic benefit of mineralocorticoid receptor antagonists in patients with acute coronary syndrome. Material and methods: We conducted a retrospective cohort study of 8318 consecutive acute coronary syndrome patients. Baseline patient characteristics were examined and a follow-up period was established for registry of death, major cardiovascular adverse events and heart failure re-hospitalization. We performed a propensity-matching analysis to draw up two groups of patients paired according to whether or not they had been treated with mineralocorticoid receptor antagonists. The prognostic value of mineralocorticoid receptor antagonists to predict events during follow-up was analysed using Cox regression. Results: Among the study participants, only 524 patients (6.3%) were discharged on mineralocorticoid receptor antagonists. Patients on mineralocorticoid receptor antagonists had a different clinical and pharmacological profile. These differences disappeared after the propensity score analysis. The median follow-up was 40.7 months. After the propensity score analysis, the cardiovascular mortality and heart failure readmission rates were similar between patients who were discharged on mineralocorticoid receptor antagonists and those whose not. The use of mineralocorticoid receptor antagonists was only associated with a reduction in major cardiovascular adverse events (hazard ratio=0.83, 95% confidence interval 0.69-0.97, p=0.001). Conclusions: Our results do not corroborate the long-term benefit of mineralocorticoid receptor antagonists to improve survival after acute coronary syndrome in a large cohort of patients with heart failure or reduced left ventricular ejection fraction and diabetes. Their prescription was associated with a significantly lower incidence of major cardiovascular adverse events during the long-term follow-up without effect on heart failure development.

Introduction and objectives: Contemporary data on the incidence and prognosis of heart failure (HF) and the influence of left ventricular ejection fraction (LVEF) in the setting of acute coronary syndrome (ACS) are scant. The aim of this study was to examine the relationship between LVEF and HF with long-term prognosis in a cohort of patients with ACS. Methods: This is a retrospective observational study of 6208 patients consecutively admitted for ACS to 2 different Spanish hospitals. Baseline characteristics were examined and a follow-up period was established for registration of death and HF rehospitalization as the primary endpoint. Results: Among the study participants, 5064 had ACS without HF during hospitalization: 290 (5.8%) had LVEF < 40%, 540 (10.6%) LVEF 40% to 49%, and 4234 (83.6%) LVEF >= 50%. The remaining 1144 patients developed HF in the acute phase: 395 (34.6%) had LVEF < 40%, 251 (21.9%) LVEF 40% to 49%, and 498 (43.5%) LVEF >= 50%. Patients with LVEF 40% to 49% had a demographic and clinical profile with intermediate features between the LVEF < 40% and LVEF >= 50% groups. Kaplan-Meier curves showed that mortality and HF readmissions were statistically different depending on LVEF in the non-HF group but not in the HF group. Left ventricular ejection fraction >= 50% was an independent prognostic factor in the non-HF group only. Conclusions: In ACS, long-term prognosis is considerably worse in patients who develop HF during hospitalization than in patients without HF, irrespective of LVEF. This parameter is a strong prognostic predictor only in patients without HF. (C) 2017 Sociedad Espanola de Cardiologia. Published by Elsevier Espana, S.L.U. All rights reserved.
