We observed the effect of angiotensin receptor neprilysin inhibitor (ARNi) with such disorder compared to valsartan. Methods: In this single-blind trial, the patients were enrolled with chronic HF aged on or above 40 years, symptomatic NYHA class II - IV, an elevated NT-proBNP above 400 pg/ml level and a reduced LVEF of 40% or less. The patients were randomly assigned 1:1 to the treatment arms either ARNi (50 mg titrated to 100 mg twice a day) or valsartan (40 mg titrated to 80 mg twice a day) and followed for a median of 88 days. The primary outcome was mode of cardiovascular death and re-hospitalization for heart failure. Changes in the level of NT-proBNP and rate of ejection fraction were also measured. Results: Cardiovascular deaths occurred 4 (8%) in the ARNi treatment arm, while 11 (22%) in the valsartan treatment arm with significant hazard ratio in the ARNi group [Hazard Ratio = 0.37;95% CI: 0.34, 0.64;p = 0.042] during a median of 88 days of follow up period and 2 (4%) of the patients from the ARNi treatment arm were hospitalized due to HF, while in the valsartan treatment arm, 10 (20%) patients were hospitalized due to HF followed by receiving treatment respectively with hazard ratio in the ARNi group [Hazard Ratio = 0.80;95% CI: 0.57, 0.92;p Conclusion: Chronic treatment with the angiotensin receptor neprilysin inhibitor (ARNi) strongly decreases the NT-proBNP as well as morbidity and mortality and increases LVEF in patients with heart failure compared to valsartan.展开更多
