  • Abstract
  • Look Inside

 We examined neurohumoral effects of an angiotensin II receptor blocker, losartan or valsartan, added to an angiotensin converting enzyme inhibitor in patients with chronic heart failure. Plasma norepinephrine, aldosterone, and atrial and brain natriuretic peptide concentration, and plasma renin activity were measured beforeand 4 weeks after losartan (50mg/day) or valsartan (80mg/day) treatment, and compared between the losartan group (n=12) and the valsartan group (n= 7). There were significant reductions in plasma norepinephrine and aldosterone concentration in both groups, but not significant differences between the groups. It is suggested that low-dose and short-term treatment with losartan or valsartan may improve neurohumoral parameters in patients with chronic heart failure to the same degree and independent of the affinity for the AT 1 receptor.
