Effect of angiotensin converting enzyme inhibition on renal function in the treatment of heart failure.
Renal hemodynamics in heart failure and the effects of angiotensin converting enzyme (ACE) inhibition on renal function are reviewed. The incidence of renal dysfunction in patients with congestive heart failure is relatively high; however, the incidence of progression of renal dysfunction during treatment with ACE inhibitors is low. The mild reduction in renal function initially observed represents the physiologic expression of blocking both the systemic and the intrarenal compensatory activities of the renin-angiotensin system. Despite small changes in blood urea nitrogen and serum creatinine noted following initiation of enalapril therapy in the two studies described, there was no further clinically significant increase in blood urea nitrogen and serum creatinine noted during continued treatment in the majority of patients, irrespective of baseline renal function. The use of enalapril as adjunctive therapy with digitalis and diuretics in patients with congestive heart failure, with appropriate adjustment of the dosages of these agents, may benefit many patients.
