Abstract |
Twenty four hour blood pressure (BP) monitoring was carried out and structural state of left ventricular myocardium assessed in 20 patients with mild and moderate hypertension before and after 24 weeks of therapy with Hyzaar - fixed dose combination of losartan (50 mg) and hydrochlorothiazide (12.5 mg). According to data of 24-hour BP monitoring the use of Hyzaar was associated with lowering of diurnal (by 26.9/17.2+/-3/2 mm Hg, p<0.001), nocturnal (by 32.6/18.9+/-3/2 mm Hg, p<0.001), pulse (p<0.001) BP, and rate of morning systolic BP rise (p<0.05), decrease of nocturnal systolic and diastolic BP variability, and improvement of 24-hour BP rhythm. Trough/peak coefficients for systolic and diastolic BP (70 and 76%, respectively) reflected sufficient and steady hypotensive effect throughout 24 hours after single dose of Hyzaar. Target BP level was achieved in 70% of patients. At the background of 24-week treatment with Hyzaar left ventricular myocardial mass index significantly decreased (from 120.1+/-3.5 to 108.6+/-3.1 g/m2, D=11.5+/-1.0, p<0.001) and became normal in 60% of patients. Correlation analysis revealed independence of cardioprotective action of therapy from its hypotensive activity. Thus therapy with Hyzaar produced hypotensive and cardioprotective effects which were independent from each other.
