Pulmonary arterial hypertension (PAH) is a complex progressive disease associated with high morbidity and mortality. Circulating serum biomarkers have the potential to optimize diagnosis and prognosis in PAH. 

The identification of ubiquitous risk factors determining long-term morbidity is crucial in infants born prematurely when aiming to develop prevention strategies.

Pulmonary arterial hypertension (PAH) in India is a substantial yet under-recognized contributor to cardiovascular morbidity and mortality. Its progressive course, nonspecific early manifestations, and heterogeneous aetiologies often lead to delayed diagnosis and fragmented care.

Red blood cell distribution width (RDW)-derived indicators have increasingly been recognized as biomarkers reflecting systemic inflammation and hematological disorders. However, the prognostic value of these indicators in critically ill patients with pulmonary hypertension (PH), especially the dynamic implications of their temporal changes, remains insufficiently elucidated. A total of 990 adult patients diagnosed with PH in the intensive care unit (ICU) based on ICD-9/10 codes were enrolled from the MIMIC-IV database. 

Part of the 'Hypoxia in pulmonary vascular research – altitude and beyond' webinar series by the High Altitude Task Force, who raise awareness and understanding of PH linked to high altitude and organise scientific conferences in regions affected by high altitudes.

Clinical worsening events are increasingly recognized as a meaningful outcome in pulmonary arterial hypertension (PAH). We applied machine-learning models to real-world data to identify clinical features that may predict clinical worsening events in PAH.

Pulmonary hypertension (PH) is a major complication of interstitial lung disease (ILD) and is associated with increased morbidity and mortality. Early recognition of PH in ILD is crucial for guiding diagnostic evaluation, initiating treatment, and considering lung transplantation. 

Respected Zeder et al. report an interesting retrospective analysis of chronic obstructive pulmonary disease (COPD) patients with pulmonary hypertension (PH) finding that male sex was independently associated with higher mortality risk [1]. We commend the authors for addressing not differences, but note two methodological issues that merit discussion.
