The relation between pretreatment serum sodium concentration and the early and late effects of captopril was examined in 77 consecutive patients with severe chronic heart failure, in whom cardiac catheterization was performed during initiation of treatment and after 2 to 8 weeks. Two groups of patients were defined: 37 patients had hyponatremia (serum sodium less than 135 mEq/liter, group A) and 40 patients had a normal serum sodium concentration (greater than or equal to 135 mEq/liter, group B). With first doses of captopril, patients in group A showed more marked hemodynamic responses than did patients in group B (p less than 0.02). The changes in mean arterial pressure and left ventricular filling pressure seen with first doses of the drug varied linearly and inversely with the pretreatment serum sodium concentration (r = -0.58 and r = -0.53, respectively); this was likely related to the finding that, before administration of captopril, the serum sodium concentration varied linearly and inversely with the logarithm of the plasma renin activity (r = -0.78). However, the pretreatment serum sodium concentration did not predict the long-term hemodynamic or clinical responses to converting enzyme inhibition. Symptomatic hypotension occurred early in the course of therapy (within 24 hours of initiating captopril therapy) in 9 (12%) of the 77 patients; 8 of these 9 had severe hyponatremia (serum sodium less than 130 mEq/liter) and comprised 53% of the 15 patients in our study with such low serum sodium concentrations.(ABSTRACT TRUNCATED AT 250 WORDS)
