'Clinical aspects' is part of the Microbes Virtual Symposium series by the iPVD, a global education programme that highlights top-notch research on inflammation and infectious PVD.
The present study aimed to evaluate the efficacy of long-term riociguat sequentially combined with balloon pulmonary angioplasty (BPA) for patients with inoperable chronic thromboembolic pulmonary hypertension (CTEPH).
COVID-19 associates with a hypercoagulant state and an increased risk for venous thromboembolic events (VTEs). Whether severe COVID-19 infection requiring extracorporeal membrane oxygenation (ECMO) support might lead to chronic pulmonary perfusion abnormalities and chronic thromboembolic pulmonary disease/hypertension remains unclear.
Therapies for inoperable chronic thromboembolic pulmonary hypertension (CTEPH) include balloon pulmonary angioplasty (BPA) and PH-specific medical therapy. This study compares survival and its predictors before and after the introduction of BPA. BPA was independently associated with survival; however, there was no difference in overall survival between the two cohorts.
In pulmonary hypertension (PH) associated with chronic lung disease (CLD), identifying patients who would benefit from pulmonary vasodilators is a significant clinical challenge because the presence of PH is associated with poorer survival. This study evaluated the severity of pulmonary circulation impairment in patients with CLD-PH using pulmonary perfusion single-photon emission computed tomography/computed tomography (SPECT/CT).
Pulmonary hypertension (PH) is a complex cardiovascular disorder characterized by elevated mean pulmonary artery pressure >20 mmHg at rest. PH is classified into five groups based on etiology, each with unique underlying causes and pathophysiological mechanisms: pulmonary arterial hypertension (PAH), PH due to left heart disease, PH due to lung disease or hypoxia, chronic thromboembolic pulmonary hypertension (CTEPH), and PH with unclear multifactorial mechanisms.
Selexipag is an oral selective agonist of the prostacyclin receptor approved to treat adults with pulmonary arterial hypertension (PAH). Selexipag is initiated at a dose of 200 μg twice daily (bid) and usually titrated up by 200 μg bid weekly (per label) or more slowly (e.g., every other week in real-world clinical practice) to the highest tolerated individualized dose (ID) ranging from 200 to 1600 µg bid.
Carnitine is required to transport fatty acid across the mitochondrial membrane to undergo beta oxidation. In addition to disorders of fatty acid metabolism, a relative carnitine deficiency has been reported in pulmonary arterial hypertension (PAH).
The prognostic significance of pretransplant N-terminal pro-brain (B)-type natriuretic peptide (NT-proBNP) level has not been investigated in lung transplant recipients. The electronic files of 173 patients with chronic lung disease who underwent lung transplantation in 2018–2022 at a tertiary medical center were retrospectively reviewed.
The PEGASUS study is the first multicentric and prospective assessment of the safety of air travel flying in pulmonary hypertension (PH) (NCT03051763). Data of air travel from 60 patients with PH was available.
