Despite major advances in antiretroviral treatment, pulmonary arterial hypertension (PAH) remains a common, severe complication in patients diagnosed with HIV.
Rheumatic heart disease (RHD) is frequently complicated by pulmonary hypertension (PH) and right ventricular (RV) dysfunction. However, the prognostic significance of invasive hemodynamic parameters obtained at index right heart catheterization (RHC) in adults with RHD and echocardiographic RV–pulmonary artery (PA) uncoupling remains incompletely defined.
Hereditary hemorrhagic telangiectasia (HHT) is an autosomal‑dominant vascular disease characterized by telangiectasias and visceral arteriovenous malformations (AVMs), commonly in the lungs, liver, and brain.
This study aimed to investigate the therapeutic effects of Poncirin on hypoxic pulmonary hypertension (HPH) and to elucidate the underlying mechanism, with a specific focus on transactive response DNA-binding protein 43 (TDP43)-mediated macrophage pyroptosis.
Mechanosensitive cation channels expressed in pulmonary arterial smooth muscle (SMC) and endothelial (EC) cells contribute to the regulation of vasoconstriction and vasodilation of the pulmonary vasculature.
Poverty and social deprivation have been associated with impaired clinical outcomes and survival in several chronic diseases. The association between poverty and clinical outcomes in patients with pulmonary arterial hypertension (PAH) remains unclear.
Pulmonary arterial hypertension (PAH) is a rare disease with poor prognosis. The same treatment is recommended in patients with PAH associated with connective tissue disease (CTD) and idiopathic PAH (IPAH).
Pulmonary hypertension (PH) comprises a heterogeneous group of disorders characterized by elevated pressure in the pulmonary arteries. Despite advances in awareness, utilization of non-invasive screening with echocardiography, increasing number of targeted therapies, and evolving clinical guidelines emphasizing referral to PH specialty centers, barriers to timely diagnosis and treatment persist.
Pulmonary arterial hypertension (PAH) is a progressive vasculopathy leading to right-sided heart failure. We have shown previously that the (NOD-like-receptor-3) NLRP3 inflammasome is activated in end-stage disease of the monocrotaline and aortocaval shunt (MCT/ACS) neointimal PAH rat model.
Whether hypoxia during popular high-altitude travel negatively affects cerebral oxygenation in vulnerable patients with pulmonary vascular disease (PVD) is unknown. We studied overnight cerebral tissue oxygen saturation (CTO) and desaturation index (cODI) in PVD-patients at 2500 m and effects of supplemental oxygen therapy (SOT).
