The regress or left ventricular (LV) hypertrophy is a main end-point of antihypertensive therapy. The aim of the present study
was to compare antihypertensive effects of two fixed combination preparations of ACE inhibitor and thiazide diuretic, enalapril 20 mg/hydrochlorthiazide
12,5 mg (Co-renitec) and losartan 50 mg/hydrochlorthiazide 12,5 mg (Hyzaar) on LV mass index (LVMI), types of left
ventricular remodeling in patients with grade II-III arterial hypertension. First group was treated with Co-renitec, second group with
Hyzaar during 24-weeks period. Results showed that both preparations significantly and to the same degree decrease LVMI. Number of
patients with normal LV geometry increases with accompanying decrease in number of patients with concentric hypertrophy and concentric
remodeling. The favorable effects were more remarkable in group treated with Hyzaar.
