| Popis: | To study the effects of the angiotensin II receptor antagonist Losartan and Amlodipine on left ventricular mass (LVM), we performed blood pressure measurements and transthoracic echocardiographies at baseline. After a 4-week placebo run-in period, 25 patients with mild-to-moderate essential hypertension were randomly allocated to active treatment with Losartan 50 mg titrated to Losartan 50 mg/hydrochlorothiazide (HCT) 12.5 mg (n = 11) or Amlodipine 5 mg titrated to 10 mg (n = 14) for 16 weeks. After treatment, blood pressure decreased significantly in both groups. LVM and LVM index (mean ± SD/median) in the Losartan group at baseline were 311 ± 101/288 g and 163 ± 55/150 g/m2 and decreased significantly to 252 ± 25/255 g and 133 ± 22/128 g/m2 (p = 0.003 for LVM; p = 0.01 for LVM index) after 16 weeks of active treatment. In the Amlodipine group LVM and LVM index decreased from 259 ± 47/243 g and 136 ± 25/ 131 g/m2 to 240 ± 42/234 g and 126 ± 24/123 g/m2 (n.s.). In conclusion, LVM decreased significantly as early as 16 weeks after initiation of antihypertensive treatment with the Angiotensin II antagonist Losartan. |
