Sacubitril/Valsartan Versus Valsartan in Heart Failure

Effect of Sacubitril/Valsartan Versus Valsartan on Left Ventricular Ejection Fraction and Biomarker in Heart Failure

The objective of this study was to identify potential prognostic factors of sacubitril/valsartan vs Valsartan treatment response.

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, 100 mg twice daily) or group 2 received valsartan (target dose, 80 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.

Inclusion Criteria:

• Patients with HF were enrolled if aged > 35 years,
• Stable symptomatic systolic chronic HF (≥ 4 weeks), with left ventricular ejection fraction (LVEF) < 35%,
• NYHA class II-III,
• Sinus rhythm and resting HR ≥ 70 beats/min on optimised standard medical therapy.

Exclusion Criteria:

• Patients with acute decompensation,
• Cerebrovascular events during the previous 6 months,
• Pregnancy, breastfeeding,
• Any valve dysfunction/abnormality,
• Active myocarditis,
• Second-degree and third-degree atrioventricular block,
• Sick sinus syndrome.
