Atrial natriuretic factor in high-altitude pulmonary hypertension: the influence of acute hypoxia on plasma atrial natriuretic factor, renin, and aldosterone concentrations in highlanders with initially normal or elevated pulmonary artery pressure and without evidence of right ventricular hypertrophy.

Abstract

Since the renin-angiotensin-aldosterone system and atrial natriuretic factor are directly involved in the regulation of hemodynamics and structural alterations in the circulatory system, the interest of investigators in the observed changes in this system during exogenous hypoxia and the resultant development of high-altitude pulmonary hypertension is quite understandable. The authors measured the plasma levels of hormones from the major vasoconstrictor neurohumoral system and from one vasodilatory system and correlated them with hemodynamic variables in native highlanders of Tien-Shan.
