Effects of indapamide on left ventricular mass and function in systemic hypertension with left ventricular hypertrophy.
Left ventricular hypertrophy (LVH) is frequently associated with hypertension and constitutes a major cardiovascular risk factor, the reduction of which should be considered when initiating antihypertensive therapy. To assess the effects of indapamide on LVH, 18 hypertensive patients were included in the study (11 men and 7 women, age 53.6 +/- 2.9 years, mean +/- standard deviation) whose supine diastolic blood pressure was greater than 95 mm Hg without (n = 11) or with (n = 7:6 beta blockers, 1 calcium antagonist) antihypertensive therapy. All presented with LVH, echocardiographically defined by a left ventricular mass index greater than 110 g/m2. After a 2-week preinclusion period, all patients received indapamide, 2.5 mg/day, for a period of 6 months. Physical examination including blood pressure measurement was performed on selection (M-1/2), before (M0), and after 1 (M1), 3 (M3) and 6 (M6) months of indapamide treatment, and echocardiography was performed at M0 and M6. Quality of life was evaluated by means of questionnaires completed by the patient and the physician, and a visual analog scale was completed by the patient at M-1/2, M0 and M6. All clinical parameters remained stable during the 2-week preinclusion period. Indapamide administration induced a highly significant reduction in both supine systolic and diastolic blood pressures from 173.9 +/- 2.9/100.5 +/- 1.2 mm Hg at M0 to 150.9 +/- 1.9/90.5 +/- 1.3 mm Hg at M1 (p less than 0.001), and 145.0 +/- 1.7/86.0 +/- 1.5 mm Hg at M6 (p less than 0.001). Similar favorable effects were observed in the upright position.(ABSTRACT TRUNCATED AT 250 WORDS)
