A pulmonary artery wedge pressure being less than 15 mmHg (also measured by right heart catheterization) excludes post-capillary bed (in the veins distal to the capillary bed) pulmonary hypertension. Pulmonary arterial hypertension is a subgroup of pulmonary hypertension and is categorized as World Health Organization as group 1. [3]
Signs of pulmonary hypertension on CT scan of the chest are: Enlargement of the pulmonary trunk (measured at its bifurcation). It is, however, a poor predictor of pulmonary hypertension in patients with interstitial lung disease. [62] A diameter of more than 27 mm for women and 29 mm for men is suggested as a cutoff. [62]
Although higher pulmonary arterial pressures are associated with the development of HAPE, the presence of pulmonary hypertension may not in itself be sufficient to explain the development of edema; severe pulmonary hypertension can exist in the absence of clinical HAPE in subjects at high altitude.

The Pulmonary Hypertension Association (PHA) is a 501(c)(3) nonprofit organization that provides support, education, advocacy, and awareness association for pulmonary hypertension. It provides information to the public about the illness and acts as a support group for those with the disease, providing medical provider location services and ...
Chronic thromboembolic pulmonary hypertension (CTEPH) is a long-term disease caused by a blockage in the blood vessels that deliver blood from the heart to the lungs (the pulmonary arterial tree). These blockages cause increased resistance to flow in the pulmonary arterial tree which in turn leads to rise in pressure in these arteries ...
Pulmonary veno-occlusive disease (PVOD) is a rare form of pulmonary hypertension caused by progressive blockage of the small veins in the lungs. [2] The blockage leads to high blood pressures in the arteries of the lungs, which, in turn, leads to heart failure .
Finally, the pulmonary pathology of PPH is very similar to that of primary pulmonary hypertension. [19] The muscular pulmonary arteries become fibrotic and hypertrophy while the smaller arteries lose smooth muscle cells and their elastic intima. One study found at autopsy significant thickening of pulmonary arteries in cirrhotic patients. [20]
A Radiographer explains an x-ray to a coal miner participating in screening. Patient education can include explaining the results of diagnostic tests. Patient education is a planned interactive learning process designed to support and enable expert patients [1] to manage their life with a disease and/or optimise their health and well-being. [2] [3]
