[Certain aspects of pulmonary hypertension].
The study concerned certain aspects of pulmonary hypertension. The most frequent factors in the aetiology of the syndrome are: 1) pressure rise in pulmonary capillaries and/or left atrium, 2) considerable rise of blood flow in the pulmonary artery, 3) reduced total blood flow in the pulmonary vascular bed. Pulmonary hypertension is divided into passive and hyperkinetic. Moreover, pulmonary hypertension of unknown aetiology exists, so called primary pulmonary hypertension, which may occur as one of three types of the disease: thromboembolic pulmonary hypertension, primary pulmonary arteriopathy, primary pulmonary thrombophlebitis.
