hypertension is defined as a mean pulmonary artery pressure (MPAP) ≥25 mm Hg at rest or 30 mm Hg on exercise.1 At the "World Symposium on Pulmonary Arterial Hypertension" in 2003, the clinical classification of pulmonary hypertension was revised2 to identify five major groups (Table 1). ...

Pulmonary arterial hypertension (PAH) is a chronic and progressive disease leading to right heart failure and ultimately death if untreated. The first classification of PH was proposed in 1973. In 2008, the fourth World Symposium on PH held in Dana Point
Baseline characteristics of the non-PH, ex-PH, and overt-PH groups, defined using the 2022 definition, are summarized in Table 1. The groups did not significantly differ in terms of age, hemoglobin and brain natriuretic peptide concentrations, comorbidities, pulmonary function (except for DLCO %...

Background: Pulmonary hypertension may result in significant morbidity and mortality after pediatric cardiac surgery. The objective of this study was to determine the incidence and outcome of severe pulmonary hypertension, defined as a ratio of pulmonary to systemic arterial pressure equal to or greater...
Pulmonary hypertension (PH) is a severe cardiopulmonary disease characterized by pulmonary vascular remodeling. Immunoglobulin E (IgE) is known to participate in aortic vascular remodeling, but whether IgE mediates pulmonary vascular disease is unknown. In the present study, we found serum IgE elevation...

Pulmonary arterial hypertension (PAH) may occur either as a primary disease of unknown cause [idiopathic PAH (IPAH)] or as an associated manifestation of other diseases or malformations [eg, congenital shunts between the systemic and pulmonary circulation; associated PAH (APAH)].1, 2 Characteristic...
