Does valsartan reduce left ventricular mass index compared to atenolol in previously untreated patients with essential hypertension and LVH?
Valsartan significantly reduces left ventricular hypertrophy in patients with essential hypertension compared to atenolol.
Left ventricular hypertrophy (LVH) represents an independent risk factor for cardiovascular morbidity and mortality, and normalization of left ventricular mass has become a desirable goal of antihypertensive treatment. In a randomized, double-blind study, the angiotensin II (AT1-receptor) antagonist valsartan (Diovan ; 80-160 mg q.d.) was compared with the beta-blocker atenolol (50-100 mg q.d.) over 8 months in previously untreated patients with essential hypertension and LVH. Sixty-nine patients were randomized, of whom 58 were evaluated by echocardiography. After 8 months of treatment in the atenolol group n = 8 with additional hydrochlorothiazide (HCTZ), initial blood pressure was reduced from 160/103 to 147/92 mm Hg (p < 0.0001). In the valsartan group (n = 9 with HCTZ), blood pressure decreased from 163/101 to 146/90 mm Hg (p < 0.0001). Left ventricular mass index decreased from 127 to 117 g/m2 in the atenolol group and from 127 to 106 g/m2 in the valsartan group. Long-term treatment with valsartan resulted in a significant reduction of LVH in patients with essential hypertension.
