Abstract

BACKGROUND AND OBJECTIVES: Hypertension is a significant cause of chronic renal injury and its effective treatment is capable of reducing the rate of renal failure. beta-Adrenoceptor antagonists (beta-blockers) have been reported to induce a deterioration in renal function, while several data have indicated a renoprotective effect of treatment with the angiotensin II type 1 receptor antagonist losartan. Previous studies of the interaction between the selective beta(1)-blocker bisoprolol and kidney function were performed only for short- and medium-term periods. The aim of this study was to compare the antihypertensive efficacy and renal and cardiac haemodynamic effects of bisoprolol with those of losartan over a 1-year time period in patients with essential hypertension. METHODS: Seventy-two patients (40 males) with recently diagnosed uncomplicated (European Society of Hypertension [ESH] criteria stage 1-2) hypertension (mean +/- SD age 52 +/- 12 years) were enrolled in the study. After a run-in period of 14 days on placebo, the patients were randomized in a double-blind, prospective study to receive either bisoprolol 5 mg or losartan 50 mg, administered once daily for 1 year. At recruitment and 12 months after treatment, cardiac output and renal haemodynamics and function were evaluated by echocardiography and radionuclide studies, respectively. RESULTS: There were no significant differences in baseline clinical data, including glomerular filtration rate and blood pressure, between the two treatment groups. At 1 year, blood pressure had decreased significantly (p < 0.001) with both treatments, and heart rate was reduced only in the group taking bisoprolol. The long-term effects on renal haemodynamics and cardiac function were similar with both drugs, the only change being a significant reduction in the filtration fraction for each group. CONCLUSIONS: These data suggest that both bisoprolol and losartan are effective agents for the treatment of patients with recently diagnosed ESH stage 1-2 hypertension. Over a 1-year period, both agents maintained good renal and cardiac performance and haemodynamics.
