Non commercial, multicentre, randomised, double-blind, comparator-controlled clinical trial. Eligible patients were randomly assigned (1:1) using a secure, central, interactive, web-based response system, to intervention or comparator arm. Time of observation 13 months [1months active up titration phase + 12 months follow up].
MAIN OBJECTIVE. Demonstration that use of sacubitril/valsartan influences parameters of right heart catheterization, including pulmonary artery pressure, and provokes changes in pulmonary circulation resistance in patients with heart failure with reduced left ventricular ejection fraction (HFrEF) and post-capillary pulmonary hypertension (PH): both isolated post-capillary (Ipc-PH) and combined post- and pre-capillary (Cpc-PH), which we predict could improve prognosis in this group of patients.~RESEARCH HYPOTHESIS. Sacubitril/valsartan used in patients with HFrEF accompanied by pulmonary hypertension due to HFrEF will reduce pulmonary artery pressure, pulmonary vascular resistance, and the incidence of secondary end-points as listed in the protocol.~STUDY OUTLINE. PRESENT-HF will show the effects of sacubitril/valsartan on pulmonary circulation pressure in patients with HFrEF and post-capillary pulmonary hypertension (PH): both isolated post-capillary (Ipc-PH) and combined post- and pre-capillary (Cpc-PH), which is expected to improve prognosis.
