Hypopituitarism has been reported in patients receiving continuous infusions of prostaglandin I2 (PGI2) analogues for pulmonary hypertension (PH). However, these patients' clinical characteristics, treatment, and prognoses remain unclear. This retrospective multicentre study included 22 patients who developed hypopituitarism while on continuous PGI2 analogue infusion between 1999 and 2021.

Pulmonary hypertension (PH) is a life-threatening condition frequently associated with exertional dyspnea. It remains diagnostically challenging due to limitations in current screening modalities. While the 6-min walk test (6MWT) has been applied for risk stratification in confirmed PH, its potential role in screening remains unexplored.

Children with chronic diseases, including pulmonary hypertension (PH), have an increased risk of anxiety and depression (AD), impacting mental health (MH), and quality of life (QoL). We sought to characterize the prevalence of AD in pediatric PH and identify associated factors. We developed a prospective cross-sectional study with 10 Pediatric Pulmonary Hypertension Network (PPHNet) centers.

This study aims to understand healthcare providers' (HCPs) decision to adopt double combination therapy with ERA + PDE5i for pulmonary arterial hypertension (PAH), and to explore whether a single tablet combination therapy (STCT) might increase adoption practices. 195 US HCPs completed a survey evaluating their PAH treatment preferences.

First approved by the US Food and Drug Administration in 2004, inhaled iloprost has become a mainstay of therapy for adults with pulmonary arterial hypertension (PAH) based on strong clinical trial evidence of its ability to improve symptoms and exercise capacity [1-3]. In 2023, however, the I-neb adaptive aerosol delivery system was discontinued, thereby limiting the availability of inhaled iloprost for new patients and promoting the ultimate discontinuation of the nebulized solution.

Pulmonary arterial hypertension (PAH) Group 1 from the World Health Organization (WHO) is a rare, severe chronic, and progressive condition. Patients with PAH have increased oxidative stress (OS) and diminished antioxidant capacity. Melatonin is a potent antioxidant hormone with reported benefits in PAH animal models. 

Cardiac output is essential to calculate pulmonary vascular resistance (PVR) and classify pulmonary hypertension (PH). Recent evidence has shown a lower agreement between thermodilution (COTD) and direct Fick (CODF) methods than historically estimated. The influence of the cardiac output measurement method on the classification of PH is poorly explored. 

While anxiety and depression are commonly reported in pulmonary hypertension (PH), limited evidence exists on how these conditions interact with the pathophysiological symptoms of PH. Fatigue and, to a lesser degree, pain are key symptoms of PH; however, they have rarely been examined as separate experiences associated with PH.
