    To the Editor, we read with great interest the article by Ntiloudi et al[1], describing hospitalization for heart failure (HF) as a powerful predictor of mortality among adults with pulmonary hypertension related to congenital heart disease (PH-ACHD). Although pulmonary arterial hypertension (PAH) targeted therapy has improved their survival, long-term complications such as HF hospitalization commonly occurred, and dismal prognosis with a mortality rate of 18.5% deeply broke our heart, thus requiring earlier diagnosis, risk stratification and therapeutic intervention.
    Hospitalization for HF, a sign of clinical worsening, is associated with poor outcomes and generally used as one of composite endpoints in PAH[2], Ntiloudi et al stated nearly one-quarter of patients were hospitalized for HF, and they encountered a ninefold increased mortality risk compared to those not-hospitalized, since NYHA functional class III/IV raised a tenfold risk of death, its combination with HF hospitalization may better predict outcomes. A previous study[3] reported 29% patients with idiopathic and associated PAH were hospitalized for acute right heart failure at least once during a 39.1-month follow up, and those with hospitalizations had worse NYHA functional class, inferior right ventricle function, lower six minute walk test (6MWT) distance and worse outcomes defined by death/transplant (67% vs 33%). These two findings indicated a potential role of HF hospitalization for identifying...
