Study will include 80 symptomatic patients with chronic HFrEF (left ventricular ejection fraction ≤35%) and New York Heart Association (NYHA) class II/III: Group 1 (N = 40) received sacubitril/valsartan (target dose, 200 mg twice daily) or group 2 received valsartan (target dose, 160 mg twice daily) in addition to recommended therapy according to physician's judgment. Analysis of biochemical parameters, cardiopulmonary exercise testing, and echocardiographic evaluation was performed at baseline and 6 months later. The primary outcome was the change in LVEF%, Lipo A, troponin I, NT-Pro BNP and neopterin levels. The secondary outcome is reporting efficacy and safety of sacubitril/valsartan vs Valsartan use and the relationship between NYHA and EF and biomarkers.
The objective of this study was to identify potential prognostic factors of sacubitril/valsartan vs Valsartan treatment response.
