Popis: Introduction: Combination of Angiotensin Receptor and Neprilysin Inhibitors (ARNI) has become the mainstay drug in treatment of Heart Failure (HF) with reduced Ejection Fraction (HFrEF). However, there are very few studies to evaluate the extent and spectrum of benefit of ARNI therapy in Indian HFrEF patients. Aim: To observe the benefits of sacubitril/valsartan (ARNI) therapy on left ventricle function, parameters of cardiac remodelling, N terminal pro Brain-natriuretic peptide (NT-proBNP), rate of rehospitalisation for HF and detailed subgroup analysis in symptomatic HFrEF patients who are already receiving optimal medical therapy. Materials and Methods: This longitudinal study was conducted at Cardiology Department of Institute of Medical Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh, India, from September 2018 to August 2020. Total 200 patients of HFrEF with previous echocardiographic records of past six months, who did not show any further improvement in left ventricle dysfunction or cardiac dimensions were included in the study out of these 200 patients, 174 (87%) completed the one year follow-up. Patients were started on ARNI initially from 100 mg/day and up titrated to 400 mg/day. At each follow-up (6 weeks, 4 months, 6 months, 9 months and 1 year) clinical examination, New York Heart Association (NYHA) functional class, 2D Echocardiography and NT-ProBNP were done. Echocardiographic parameters of Cardiac Reverse Remodelling (CRR) i.e., Left Ventricular Ejection Fraction (LVEF), Left Ventricular End Diastolic Diameter (LVEDD), Left Ventricle End-Systolic Diameter (LVESD) were recorded at each follow-up. All categorical variables were shown in the form of frequency, mean with standard deviation and percentage. Intergroup comparison between different time periods was done by one-way Analysis of Variance (ANOVA) and paired t-test. A p-value
