title: Primary pulmonary hypertension with severe systemic hypertension, Raynaud's phenomenon and relative polycythemia.
abstract: A 32-year-old Japanese man was hospitalized for evaluation of unconsciousness. He was diagnosed as having primary pulmonary hypertension (PPH) with severe systemic hypertension, Raynaud's phenomenon and relative polycythemia. Hemostatic studies revealed increased coagulation and decreased fibrinolysis, similar to findings of chronic disseminated intravascular coagulation (DIC). Although activation of coagulation and systemic hypertension were improved after treatment with phlebotomy and administration of nifedipine, enerapril and warfarin, pulmonary hypertension was unchanged, suggesting that irreversible change had already occurred in the pulmonary arteries. Those complications could modify the process of pulmonary hypertension by inducing a hyperviscosity state.
