EFFECTS OF SACUBITRIL/VALSARTAN ON THE ARTERIAL STIFFNESS AND LEFT VENTRICULAR-ARTERIAL COUPLING IN PATIENTS WITH HEART FAILURE WITH REDUCED EJECTION FRACTION

Aim. To study the effects of sacubitril/valsartan on left ventricular-arterial coupling (LVAC) and arterial stiffness in HFrEF patients.Material and methods. Arterial stiffness by applanation tonometry and LVAC – by two-dimensional echocardiography were evaluated in 18 patients with compensated HFrEF (age 69Ѓ}9 years, 89% male, arterial hypertension – 83%, diabetes – 39%, myocardial infarction – 89%, left ventricular ejection fraction 32Ѓ}4%) initially and after 6 and 12 months of therapy based on sacubitril/valsartan. LVAC was calculated as the Ea (arterial elastance)/ Ees (left ventricular elastance) ratio. Differences were considered statistically significant at p10 m/s). The decrease in PWV (from 11.5Ѓ}2.9 to 10.2Ѓ}2.9 m/s, p
