Various erythropoietic abnormalities are highly prevalent among patients with pulmonary arterial hypertension (PAH) and associated with worse disease severity. Given the poorly understood yet important roles of dysregulated erythropoiesis and iron metabolism in PAH, we sought to further characterize the hematologic and iron profiles in PAH and their relationship to PAH severity.

Hemoptysis is a frequently encountered manifestation in cases of acute pulmonary thromboembolism (PTE), significantly impacting clinical decision-making. Despite its clinical relevance, studies focusing on patients with acute PTE and hemoptysis are notably scarce.

Pulmonary thromboendarterectomy (PTE) is the treatment of choice for patients with operable chronic thromboembolic pulmonary hypertension (CTEPH) based on the ability to yield dramatic improvements in hemodynamics and association with improved survival.

Selexipag is indicated for the treatment of pulmonary arterial hypertension (PAH), including PAH associated with connective tissue disease (CTD), and further insights into the management of selexipag-treated PAH-CTD patients in clinical settings are needed.

The objective of this study is to provide a positron emission tomography (PET) imaging modality targeting vascular endothelial growth factor receptors (VEGFR) for the early noninvasive detection and assessment of pulmonary arterial hypertension (PAH) severity. 

Chronic obstructive pulmonary disease (COPD) is a persistent and progressive disorder characterized by airway or alveolar abnormalities, commonly leading to pulmonary hypertension (PH).

I am writing this as I return from a conference of over 10,000 professionals dedicated primarily to the research and clinical care of respiratory disease.

Post-acute sequelae of Coronavirus (PASC), or Long COVID, has emerged as a critical health concern.

Pulmonary arterial hypertension (PAH) is a poorly understood disease of the small pulmonary arteries. Pulmonary vascular remodeling and progressively rising pulmonary vascular resistance are hallmarks of the disease that ultimately result in right heart failure.
