RESUMO
Objective To explore the effects of Atorvastatin and Simvastatin on serum levels of lipid,high sensitive C-reactive protein (hs CRP)and ventricular remodeling in patients with acute coronary syndromes(ACS).Methods In this prospective study,96 patients with acute coronary syndrome were admitted in our hospital from December 2014 to September 2016.In the prospectively study,they were randomized into Atorvastatin group(Atorvastatin 20 mg daily,n =48) and Simvastatin group(Simvastatin 40 mg daily,n=48),and serum levels of hs CRP,lipids and changes in myocardial function were detected and compared between two groups before and after treatment.Results The serum levels of hs-CRP and lipids were significantly lower in Atorvastatin group than in Simvastatin group at 8 weeks after treatment(P＜0.05).At the end of the treatment,the levels of left ventricular reject fraction and left ventricular end-diastolic volume index were improved (all P ＜ 0.05) in two groups,but significantly higher in Atorvastatin group [(44.8 ± 6.3) ％ and (62.7 ± 10.4)] than in Simvastatin group [(48.9 ± 6.9) ％ and (67.9 ± 10.5) respectively,all P ＜ 0.05).Conclusions Simvastatin and Atorvastatin can effectively promote the decrease in levels of blood lipids and inflammatory reaction,and help to improve the myocardial function in patients with acute coronary syndrome,but Atorvastatin effects are more significant.
