Abstract
BACKGROUND: To observe the changes of cardiac structure and function in elderly patients with heart failure with reduced ejection fraction (HFrEF) after taking Sacubitril-Valsartan for 6 months. METHODS: Elderly patients with HFrEF hospitalized in Beijing Anzhen Hospital from May 2019 to May 2020 were enrolled continuously in the single-center, retrospective, cohort study. Patients' Echocardiographs were examined for the evaluation of their cardiac condition. The primary outcomes were changes in cardiac function and structure at the sixth month after discharge, including left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left atrial diameter (LAD), interventricular septum thickness (IVST), left ventricular posterior wall thickness (LVPWT) and left ventricular mass index (LVMI). RESULTS: A total of 336 elderly patients with HFrEF were enrolled in this study, with an average age of 69.8 years, including 268 males (79.8%). Compared to the admission levels, the LVEF after taking Sacubitril-Valsartan for 6 months was markedly improved (48.49% vs. 39.07%, P<0.01), while the LVEDD (54.70 vs. 59.97 mm, P<0.01), LVESD (40.59 vs. 47.59 mm, P<0.01), LAD (48.59 vs. 52.45 mm, P<0.01) and LVMI (105.16 vs. 125.20 g/m2, P<0.01) decreased. Similar results were obtained in the subgroups of patients who were diagnosed with HFrEF on admission. In men, NHYA II and NHYA III subgroups, cardiac function improved significantly. CONCLUSIONS: Sacubitril-Valsartan can improve the cardiac function and structure of elderly patients with HFrEF. 2021 Cardiovascular Diagnosis and Therapy. All rights reserved.
