title: Effects of delapril in combination with indapamide on blood pressure and left ventricular mass in elderly hypertensive patients.
abstract: We present a single-blinded, placebo-controlled trial of the effects on blood pressure and left ventricular mass and of the safety of a combined antihypertensive treatment with delapril, a new nonsulfhydryl angiotensin-converting enzyme inhibitor, and indapamide, a sulfonamide diuretic. We studied 28 elderly patients aged 65-85 years (mean age, 69 +/- 1) with sitting systolic/diastolic blood pressure of 160-200/95-115 mm Hg (at the end of the placebo period). After a 2-week placebo run-in, patients took 30 mg delapril in combination with 1.25 mg indapamide once daily for 24 weeks. Twenty-four-hour ambulatory blood pressure was monitored and M- and B-mode echocardiography were performed before and after 24 weeks of treatment. Blood pressure decreased from 156 +/- 1.5/101 +/- 1 mm Hg before treatment to 133 +/- 1/73 +/- 1 mm Hg after treatment. The total blood pressure burden also decreased; the percentage of measurements with a systolic blood pressure > or = 140 mm Hg and a diastolic blood pressure > or = 90 mm Hg decreased from 48.7% +/- 5%/31.5% +/- 4.3% to 23.5% +/- 4%/20.5% +/- 2.9% (p < 0.0005 and p < 0.05). The area under the curve of the 24-hour blood pressure decreased from 250 +/- 41/103 +/- 21 mm Hg to 97 +/- 21/37 +/- 8.5 mm Hg (p < 0.001 and p < 0.005). The left ventricular mass index (LVMI) in the 15 patients with pretreatment left ventricular hypertrophy was reduced after therapy from 167.5 +/- 8.5 g/m 2 to 152.2 +/- 7.6 g/m 2 (p < 0.05). A positive correlation was observed between percent changes of the area under the curve of the 24-hour diastolic blood pressure and percent changes of LVMI (r = 0.6; p < 0. 05) in the 15 patients with left ventricular hypertrophy. Only 2 patients reported side effects: 1 developed skin rash and 1 developed headache. The safety of the treatment was confirmed by laboratory tests. In elderly hypertensive patients, the combination of delapril and indapamide at low doses reduced blood pressure and had favorable effects on LVMI with few side effects.
