Hypertension develops in about 10% to 50% of patients with nephrosis or cirrhosis and peripheral edema, but the hemodynamic mechanism of the hypertension and its reversal by diuretic therapy has not been elucidated. In eight patients with marked edema and mild hypertension, diuretics (furosemide and spironolactone) decreased mean arterial pressure because of concurrent decrease in cardiac output and total peripheral resistance. Neither total blood volume nor plasma volume were decreased by the diuretics and the decrease in body weight was therefore attributed to the decrease in interstitial fluid volume. This, in turn, resulted in increased venous capacitance (as can be judged from the diuretic-induced decrease in the ratio of cardiopulmonary blood volume/total blood volume).
