Heart Failure With Preserved Ejection Fraction
Conditions
Brief summary
This is a study to evaluate whether macitentan is an effective and safe treatment for patients with heart failure with preserved ejection fraction (HFpEF) and pulmonary vascular disease. The primary objective is to evaluate whether macitentan 10 mg reduces N-terminal pro-brain natriuretic peptide (NT-pro-BNP) as compared to placebo in these patients.
Interventions
macitentan 10 mg; film-coated tablet; oral use
film-coated tablet (identical to the macitentan tablet); oral use

The KCCQ is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. Clinical summary score is one of the quality of life variable of interest derived from KCCQ. Clinical summary score is the mean of domains: physical limitations score (6 items) and total symptom score (2 items \[symptoms frequency and symptom burden\]). The score is calculated by summing domain responses and then transforming scores to a 0-100 unit scale with higher scores indicating better health status. |
