  • Title: Treatment of pulmonary hypertension.
    Author: Denolin H, Mathey DG.
    Journal: Herz; 1986 Jun; 11(3):169-75. PubMed ID: 2875021.
    Abstract:
    Reversible causes of pulmonary hypertension, such as mitral stenosis or pulmonary embolism, should be corrected causally. The therapy of pulmonary hypertension is difficult in those diseases where the causes or mechanisms are not understood or are unknown. In chronic obstructive lung disease, the primary objective is to improve airflow and alveolar ventilation (theophylline, beta-sympathicomimetics). Long-term oxygen (more than 18 hours a day) should be used in patients with paO2 below 55 mm Hg, since a reduction in pulmonary vascular resistance and a prolonged survival has been demonstrated. The role of vasodilator therapy (hydralazine, nitrates, diazoxide, captopril, calcium-blockers and others) in chronic obstructive lung disease remains uncertain. In primary pulmonary hypertension, a pulmonary vasodilator is recommended after demonstrating (for example with an infusion of prostaglandin I2), that the increased pulmonary vascular resistance is still reversible. The initiation of therapy should be performed cautiously under hemodynamic monitoring.
