Proliferation of pulmonary arterial smooth muscle cells, endothelial dysfunction, oxidative stress, and inflammation promotes the development of pulmonary hypertension. Resveratrol is a polyphenolic compound that exerts antioxidant and anti-inflammatory protective effects in the systemic circulation, but its effects on pulmonary arteries remain poorly defined. The present study was undertaken t...

The variability of pulmonary arterial pressure, the relation of pulmonary pressure to systemic pressure, pulmonary pressure responses to stimuli (exercise, hypoxia, smoking, free ambulation), and plasma catecholamine responses were assessed in five patients with primary pulmonary hypertension. Ambulatory monitoring techniques provided data for the computerised analysis of continuous, beat-to-be...

Congenital heart diseases are the most common congenital malformations and account for about eight cases per 1000 births and are often associated with pulmonary arterial hypertension. Increased shear stress and the excess flow through the pulmonary vascular bed due to a systemic-to-pulmonary shunt lead to the development of pulmonary vascular disease and an increase in pulmonary vascular resist...

Pulmonary arterial hypertension (PAH) is a severe and fatal disease with a prevalence of 15 cases in a million[1] and characterized by increased pulmonary vascular resistance and right heart failure. PAH can be idiopathic (IPAH), familial (FPAH), or associated with other disorders. In 1984 the National Institute of Health (NIH) compiled the first large registry of PAH patients (all IPAH, FPAH, ...

In patients with systemic sclerosis heart involvement is often manifest, associated with poor prognosis and increased mortality. Cardiac involvement may be manifested by myocardial disease, arrhhythmias, conduction system disturbances, pericardial abnormalities and right heart failure, which develops as a complication of pulmonary arterial hypertension and significantly influences the disease p...

Pulmonary arterial hypertension of variable degree is commonly associated with adult congenital heart disease. Depending on size and location of the underlying cardiac defect as well as on repair status, pulmonary arterial hypertension may present with or without reversed shunting and associated cyanosis (ie, Eisenmenger syndrome). We review available data on etiology, clinical presentation, pr...

Broilers that are susceptible to pulmonary hypertension syndrome (PHS, ascites) have an elevated pulmonary arterial pressure (PAP) when compared with PHS-resistant broilers. Two distinctly different syndromes, pulmonary arterial hypertension and pulmonary venous hypertension (PVH), both are associated with increases in PAP. Pulmonary arterial hypertension occurs when the right ventricle must el...
