Objective To compare the efficacy of indapamide sustained release (SR) 1.5
mg and enalapril 20 mg at reducing left ventricular mass index (LVMI) in hy
pertensive patients with left ventricular hypertrophy (LVH).
Design The LIVE study (left ventricular hypertrophy regression, indapamide
versus enalapril) was a 1 year, prospective, randomized, double-blind study
. For the first time, a committee validated LVH before inclusion, provided
on-going quality control during the study, and performed an end-study readi
ng of all echocardiograms blinded to sequence.
Setting European hospitals, general practitioners and cardiologists.
Patients Hypertensive patients aged greater than or equal to 20 years with
LVH (LVMI in men >120 g/m(2); LVMI in women >100 g/m(2)). Data were obtaine
d from 411 of 505 randomized patients.
Interventions Indapamide SR 1.5 mg, or enalapril 20 mg, daily for 48 weeks.
Main outcome measures LVMI variation in the per-protocol population.
Results Indapamide SR 1.5 mg significantly reduced LVMI (-8.4 +/- 30.5 g/m(
2) from baseline; P < 0.001), but enalapril 20 mg did not (-1.9 +/- 28.3 g/
m(2)). Indapamide SR 1.5 mg reduced LVMI significantly more than enalapril
20 mg: -6.5 g/m(2), P = 0.013 (-4.8 g/m(2) when adjusted for baseline value
s; P = 0.049). Both drugs equally and significantly reduced blood pressures
(P < 0.007), without correlation with LVMI changes. Indapamide SR progress
ively reduced wall thicknesses throughout the 1-year treatment period. In c
ontrast the effect of enalapril observed at 6 months was not maintained at
12 months.
Conclusions Indapamide SR 1.5 mg was significantly more effective than enal
april 20 mg at reducing LVMI in hypertensive patients with LVH. J Hypertens
