ABSTRACT
AIM: Treatment with sacubitril/valsartan (S/V) significantly improves cardiovascular morbidity, mortality, quality of life and prolongs the survival of chronic heart failure patients with reduced ejection fraction. The aim of the study was to evaluate changes in ejection fraction, NT-proBNP and glomerular filtration after 12 months of sacubitril/valsartan treatment. METHODS: 30 patients (28 men) with chronic heart failure with reduced ejection fraction, functional classes NYHA II-III, EF LK < 40%, NT-proBNP (> 450 ng/l), with glomerular filtration > 0.5 ml/s/1.73 m2, with a potassium < 5.4 mmol/l were classified in the study. S/V treatment was started at systolic blood pressure > 100 mmHg. Ejection fraction, glomerular filtration rate and NT-proBNP values were compared before treatment and after 12 months of S/V treatment. The number of hospitalizations and deaths was also monitored. RESULTS: During 12 months of S/V treatment there was a significant improvement in left ventricular ejection fraction (median initial 26.3%, after treatment 36.3%, difference 7.5%, p.
