Effects of simvastatin on left ventricular hypertrophy and function in rats with aortic stenosis %K %X AIM: To investigate the effects of simvastatin (Sim) on left ventricular hypertrophy in rats with pressure-overload cardiac hypertrophy. METHODS: The left ventricular hypertrophy (LVH) of rats was induced by partly occluding abdominal aorta below right renal artery. The rats were given i.g. Sim (1.8 and 3.6 mg.kg-1.d-1) for 8 wk. Three days after operation, left ventricular function was measured. Then the left ventricle (LV) + septum and the right ventricle (RV) were weighed. Hydroxyproline content of LV was measured. RESULTS: Eight weeks later, in the LVH group, LV weight (LVW), LVW/body weight (BW), LVW/RV weight (RVW), LV ending diastolic pressure (LVEDP), and hydroxyproline content increased by 36%, 51%, 28%, 92%, and 23%, respectively (all P < 0.01) compared with the sham group. LV + dp/dtmax and -dp/dtmax decreased by 39.2% and 39.4% (all P < 0.01). After the rats were given i.g. Sim 3.6 mg.kg-1.d-1, LVW, LVW/BW, LVW/RVW, left ventricle ending diastolic pressure (LVEDP), and hydroxyproline content decreased by 22%, 21%, 23%, 24%, and 11% compared with LVH group (all P < 0.01), LV + dp/dtmax and -dp/dtmax increased by 60% and 32% (all P < 0.01). CONCLUSION: Sim inhibited development of LV hypertrophy and improved LV function in rats with aortic stenosis. %U http://www.chinaphar.com/article/view/7637 %V 20 %N 4 %P 345-348 %@ 1745-7254
