[Interrelations of pulmonary and systemic hemodynamics in hypertension]

A comprehensive study of the systemic and pulmonary hemodynamics, performed in 198 hypertensive patients showed them to have reduced volume of blood circulating in the lungs due to enhanced postcapillary tone. Impairment of arterial blood flow in the lungs and development of pulmonary hypertension fail to keep pace with changes in the systemic circulation.
