Background Nowadays, the studies mainly focus on the function of decreasing the inflammatory factor and improving the functions of endothelium, but the Methods The 2-kindey, 1-clip hypertensive rats effects of statins on ventricular remodeling are rarely studied. （2K1C, Goldblatt） were prepared with Sprague-Dawley （SD） rat. SD rats were randomly divided into three groups： control rats, hypertensive rats and hypertensive rats treated with atorvastatin （2 mg·kg^-1·d^-1）. After 6 weeks, systolic blood pressure （SBP） was measured using the tail-cuff method. The plasma concentration of angiotensin Ⅱ and renin activity were determined by radioimmunoassay. The heart weight, the ratio of left ventricular weight and body weight was calculated. Results The plasma concentration of angiotensin Ⅱ （106.4±7.8） ng/L and renin activity （20.6±2.4） ng/L were significantly increaed in hypertensive rats compared with normal rats [ （72.3±5.4） ng/L and （12.5±3.7） ng/L] （P 〈 0.01）. The heart weight （1.46 ± 0.09）g, the ratio 3.54±0.19 （ × 10^-3） of left ventricular weight and body weight in hypertensive rats were obviously higher than that in normal rats [（0.98±0.07）g and （2.28 ± 0.06） × 10^-3] （P 〈 0.01）. After treatment with atorvastatin, the plasma concentration of angiotensin Ⅱ （68.3 ± 6.9） ng/L and renin activity（8.7 ± 2.3 ）ng/L, heart weight（1.05± 0.04）g, the ratio 2.36 ± 0.07 （×10^-3） above were decreased significantly, there were no difference between the group of hypertensive rats and the normal. Conclusions Atorvastatin can decrease the ratio of left ventricular weight and body weight and has the effects on cardiovascular remodeling in hypertensive rats.
