The effects of perindopril and metoprolol on left ventricular hypertrophy (LVH) and function were studied in 47 essential hypertensive patients with LVH. Previous antihypertensive drugs were discontinued for at least 2 weeks, after which patients were randomly divided into 2 groups. 25 subjects were treated with perindopril 4 to 8 mg once daily in the morning (Group A) and 22 subjects with metoprolol 25 to 62.5 mg twice daily (Group B). The subjects were evaluated before and after 4 and 8 weeks of treatment by use of echocardiography. Before treatment LV mass indexes (LVMI) of two groups were respectively 143.2 +/- 21.3 g/m2 and 140.6 +/- 23.7 g/m2 (P > 0.05). In Group A, reduction of LVMI occurred after 4 weeks of treatment, and more pronounced after 8 weeks (from 143.2 +/- 21.3 g/m2 to 126.6 +/- 15.3 g/m2, P < 0.001), whereas reduction of LVMI occurred only after 8 weeks in Group B (from 140.6 +/- 23.7 g/m2 to 133.4 +/- 13.2 g/m2, P < 0.001). In addition, there was a significant (P < 0.05) difference in LVMI between the two groups after 8 weeks. LV systolic function remained unchanged, whereas E/A increased significantly (P < 0.001) in two groups after 8 weeks. In conclusion, antihypertensive treatment with perindopril and metoprolol induced a significant regression of LVH associated with improvement in LV diastolic performance. Perindopril, compared with metoprolol, was more effective in reversing LVH.
