  2. Pulmonary arterial hypertension - Wikipedia

    en.wikipedia.org/.../Pulmonary_arterial_hypertension

    PAH is definitively diagnosed with a right heart catheterization showing a mean pulmonary arterial pressure greater than 20 mmHg at rest, with a pulmonary vascular resistance being 3 Woods Units or greater (indicative of pulmonary hypertension in the pre-capillary vasculature; the arteries and arterioles), and a pulmonary artery wedge pressure ...

    en.wikipedia.org/wiki/Pulmonary_hypertension

    Pulmonary hypertension is defined as a mean PAP of at least 20 mm Hg (3300 Pa) at rest, and PAH is defined as precapillary pulmonary hypertension (i.e. mean PAP ≥ 20 mm Hg with pulmonary arterial occlusion pressure [PAOP] ≤ 15 mm Hg and pulmonary vascular resistance [PVR] > 3 Wood Units). [58]

    en.wikipedia.org/wiki/Polycyclic_aromatic...

    A Polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings. Most are produced by the incomplete combustion of organic matter — by engine exhaust fumes, tobacco, incinerators, in roasted meats and cereals, [ 1 ] or when biomass burns at lower temperatures as in forest fires .

  6. Chronic thromboembolic pulmonary hypertension - Wikipedia

    en.wikipedia.org/wiki/Chronic_thromboembolic...

    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 ...

  7. Pulmonary Hypertension Association - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_Hypertension...

    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 ...
