Pulmonary arterial hypertension (PAH) significantly impacts mortality and quality of life. Access to specialized care may differ between urban and rural patients, potentially influencing outcomes. This study compared the clinical course and treatment patterns of PAH patients from urban and rural settings treated at a single comprehensive care center. 

Pulmonary hypertension due to interstitial lung disease (PH-ILD) is associated with high morbidity and mortality. Real-world patients initiating inhaled treprostinil are not well-characterized. 

Patients with Eisenmenger syndrome (ES) are at increased risk of thrombotic events, especially in pulmonary vessels. However, both the prevalence and risk factors of pulmonary arterial thrombosis (PAT) have been varied greatly. In this study we sought to examine the prevalence of PAT in adult patients with ES and to identify risk factors.

Pulmonary arterial hypertension (PAH) is a life-threatening condition characterized by elevated pulmonary vascular resistance. Despite recent advances, early diagnosis remains challenging due to nonspecific symptoms.

Pulmonary hypertension (PH) is a common complication in interstitial lung disease (ILD), but the additional burden it imposes on patients and healthcare systems is not well characterized. This retrospective analysis of claims data from the US Merative MarketScan database assessed hospitalization rates and costs over 2 years in patients with connective tissue disease-related ILD (CTD-ILD) and non-CTD-ILD with or without PH (between January 2017 and December 2019). Index was the date of first ILD claim; baseline was the 12-month preindex period.

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.

Idiopathic Pulmonary fibrosis (IPF) is a debilitating lung condition marked by chronic progression and reduced lung function. This study aimed to explore the functional role and regulatory mechanism of circular RNA circ_0044226 in the pathogenesis of pulmonary fibrosis. 

Pulmonary endarterectomy (PEA) is a highly effective treatment for chronic thromboembolic pulmonary hypertension (CTEPH). However, persistent or recurrent pulmonary hypertension (persistent/recurrent PH) following surgery can adversely impact patients’ outcomes. 

Right ventricular (RV) dysfunction is a critical yet often underrecognized determinant of prognosis in patients with advanced interstitial lung disease (ILD) undergoing lung transplant evaluation.
