Lung vasculature arises from both pulmonary and systemic (bronchial) circulations. Remodeling and structural changes in lung vasculature have been recognized in end-stage fibrotic lung diseases such as idiopathic pulmonary fibrosis (IPF) but have not been well characterized.
Overweight and obesity have emerged as modifiable risk factors for right ventricular (RV) phenotypic changes, but their genetic relationship remains unclear. This study examined RV phenotypes using cardiac magnetic resonance imaging in European participants from the UK Biobank without overt heart disease.
Juvenile systemic sclerosis (jSSc) associated pulmonary hypertension (PH) is rare, but, the leading cause of morbidity and mortality in jSSc. This is a case of a 10-year-old girl whose initial presentation of positive U3-RNP antibody jSSc included diffuse skin findings, severe pulmonary arterial hypertension, and right ventricular failure.
This study aimed to investigate the vascular effects of a radiofrequency electromagnetic field (RF-EMF) applied in the lung ischemia and reperfusion (IR) model on the hypoxia-inducible factor 1 alpha (Hif-1α)/endothelial nitric oxide synthase (eNOS) pathway and B cell lymphoma 2 (BCL2)/BCL-2 associated X protein (BAX) signaling.
Lung transplantation (LT) is a well-established therapeutic option for patients with advanced chronic respiratory diseases. This study aims to assess the prevalence and clinical impact of Group 2 pulmonary hypertension (PHg2) in LT recipients, comparing it with Group 3 pulmonary hypertension (PHg3).
Single-center pilot study suggests a threefold increase in self-reported history of adverse pregnancy outcomes (APO) among women with subsequent diagnosis of pulmonary arterial hypertension (PAH). Females with PAH and a history of APO were younger and had higher mean pulmonary artery pressures at diagnosis compared to those without a history of APO.
Pulmonary arterial hypertension (PAH) requires lifelong medication, with patients taking an average of 12 tablets/day. Several chronic diseases can be treated with a fixed-dose combination (FDC) tablet, decreasing patient pill burden and increasing adherence.
There is a need for objective, continuous and remote assessment of exercise capacity in patients with pulmonary arterial hypertension (PAH). Using data from the TRACE study, in which 108 adult patients with PAH were continuously monitored with a wrist-worn accelerometer, we evaluated whether actigraphy can facilitate continuous monitoring of exercise capacity.
Patients with congenital heart disease-related pulmonary arterial hypertension (CHD-PAH) often require regular follow-up through invasive right heart catheterization (RHC) to assess disease progression and potential interventions.
