Purpose: To examine the association between obesity and pulmonary arterial hypertension (PAH). Methods: This retrospective case-control study consisted of patients with PAH (N=207) and controls seen at a pulmonary clinic for reasons other than PAH (N=965). All patients were evaluated between 1992 and 2006 at Mayo Clinic in Jacksonville, Florida. Obesity was defined as body mass index (BMI) of 3...

Mutations in gene encoding for bone morphogenetic protein type 2 receptor (BMPR-2) have been reported in pulmonary arterial hypertension (PAH), but their functional relevance remains incompletely understood. BMP receptors expression was evaluated in human lungs and in cultured pulmonary artery smooth muscle cells (PASMCs) isolated from 19 idiopathic PAH patients and 9 heritable PAH patients wit...

Erythropoietin (EPO) mobilises endothelial progenitor cells and promotes neovascularisation in heart failure. The present authors studied the effects of EPO on pulmonary vascular and cardiac remodelling in a model for flow-associated pulmonary arterial hypertension (PAH). PAH was induced in adult male Wistar rats by the injection of monocrotaline combined with an abdominal aortocaval shunt 1 we...

Efflux transport of para-aminohippuric acid (PAH) across the blood-brain barrier (BBB) has been demonstrated by use of the brain efflux index (BEI) method. PAH was eliminated from the ipsilateral cerebrum extensively with an apparent efflux rate constant of 0.0587 (min-1) after microinjection into a cerebral cortex region termed Par2. This efflux transport showed a saturation with the Michaelis...

Right heart function is the main determinant of prognosis in pulmonary arterial hypertension (PAH). At present, no treatments are currently available that directly target the right ventricle, as we will demonstrate in this article. Meta-analysis of clinical trials in PAH revealed that current PAH medication seems to have limited cardiac-specific effects when analysed by the pump-function graph....

Pulmonary arterial hypertension (PAH) is a progressive pulmonary vasoproliferative disorder characterized by the development of unique neointimal lesions, including concentric laminar intima fibrosis and plexiform lesions. Although the histomorphology of neointimal lesions is well described, the pathogenesis of PAH and neointimal development is largely unknown. After three decades of PAH pathob...

Pulmonary arterial hypertension (PAH) is a serious complication of congenital heart disease (CHD). Without early surgical repair, around one-third of paediatric CHD patients develop significant PAH. Recent data from the Netherlands suggest that >4% of adult CHD patients have PAH, with higher rates in those with septal defects. A spectrum of cardiac defects is associated with PAH-CHD, although m...

OBJECTIVE To investigate the relationship between P-selectin gene polymorphism and congenital heart disease (CHD) with pulmonary hypertension (PAH). METHODS 58 CHD patients with PAH (PAH-CHD), 43 CHD patients without PAH and 205 healthy subjects were included in this study. The concentration of plasma P-selectin was determined by ELISA kits; the direct sequencing of PCR products was used to a...

BACKGROUND Pulmonary artery hypertension (PAH) is a proliferative disorder associated with enhanced pulmonary artery smooth muscle cell proliferation and suppressed apoptosis. The sustainability of this phenotype required the activation of a prosurvival transcription factor like signal transducers and activators of transcription-3 (STAT3) and nuclear factor of activated T cell (NFAT). Because t...

Pulmonary arterial hypertension (PAH) is a serious and often fatal disease. It is a panvasculopathy of the pulmonary microcirculation characterized by vasoconstriction and arterial obstruction due to vascular proliferation and remodeling and ultimately right ventricular failure. Mitochondrial dysfunction is a universal finding in pulmonary vascular cells of patients with PAH, and is mechanistic...
