Pulmonary arterial hypertension
Pulmonary arterial hypertension is a subgroup of a specific subgroup of pulmonary hypertension (PH) defined as a condition of slowly progressive disorder as a result of abnormally high blood pressure in the blood vessel, including pulmonary artery, pulmonary vein, or pulmonary capillaries, that carries blood from the heart to the lungs due to narrowing in diameter of most of the very small arteries throughout the lungs of that increased resistance to blood flow, leading to right heart failure and death. Because the phrase of pulmonary arterial hypertension is long and pulmonary hypertension is a bit shorter the phrase, pulmonary hypertension is often used in place of pulmonary arterial hypertension(a). According to statistic, approximately over 1,000 new cases of pulmonary arterial hypertension are diagnosed each year, in the United States alone.
B. In Herbal medicine perspective
1. Radix Astragali
In the study of Sixty rats divided into three groups: hypoxia group, hypoxia + RA group and normal control group to observe the inhibitory effects of Radix Astragali (RA) on hypoxic structural remodeling of intraacinar pulmonary arteries (IAPA) and pulmonary hypertension (PHT), showe d that compared with the result of hypoxia + RA group, RA could relieve IAPA wall cell injuries and dilate the constricted IAPA induced by hypoxia. RA could also inhibit hypertrophic changes in the tunica media and proliferation of adventitial cells of the IAPA and muscularization of nonmuscular arteries(38).
2. Radix Peucedani
According to the study by the Department of Pathology, Cardiovascular Institute, RP could not only antagonize IAPA contraction caused by hypoxia and lower the resistance of pulmonary circulation, inhibit the cell proliferation and hypertrophy of adventitial cells of pulmonary artery, but also reverse the change in structure and function of pulmonary artery. It suggests that RA plays a key role in inhibiting hypoxic structural remodeling of IAPA and pulmonary hypertension(39).
