No effect of rosuvastatin on left ventricular hypertrophy in patients with hypertension: a prospective randomised open-label study with blinded endpoint assessment

This study tested the hypothesis that statins may reduce left ventricular hypertrophy (LVH) in patients with hypertension and LVH. A prospective randomised open-label study with blinded endpoints assessment was performed in 142 patients. Inclusion criteria were hypertension, left ventricular ejection fraction ≥50% and echocardiographic determined LVH, defined as a left ventricular mass index (LVMI) of ≥ 100 g/m(2) in women and ≥ 116 g/m(2) in males. Patients were randomised between rosuvastatin 20mg once daily vs control. For each patient an echocardiogram and blood samples were obtained. These tests were repeated after 6 months. Baseline characteristics: mean age was 62 ± 11year and 62 (44%) were male. In both groups, there was a non-significant reduction in LVMI: 118 ± 22 to 111 ± 19 g/m(2) in the control group and 118 ± 21 to 114 ± 22 in the rosuvastatin group (p=0.376 for the comparison between rosuvastatin and control after 6 months). After six months, LDL-cholesterol was reduced from 3.5 ± 1.0 to 2.1 ± 1.2 mmol/L (40% reduction) in the rosuvastatin group and remained unchanged in the control group (3.5 ± 0.9 vs 3.6 ± 0.9 mmol/L. Hs-CRP decreased more with rosuvastatin compared to control (-38% vs -15%, p=0.006) There was no significant reduction in NT-pro-BNP levels after 6 months. Rosuvastatin does not reduce LVH despite a large LDL reduction in patients with hypertension and LVH
