Comparison of therapeutic effect and safety between atorvastatin and simvastatin in patients with angi-na pectoris of coronary heart disease / 心血管康复医学杂志

ABSTRACT

Objective:To compare therapeutic effect and safety between atorvastatin and simvastatin treating angina pectoris of coronary heart disease (CHD).Methods:A total of 150 patients with chronic stable angina pectoris (SAP)of CHD were selected and randomly and equally divided into atorvastatin group and simvastatin group accord-ing to number table method.Changes of angina pectoris attack frequency,duration,degree of pain,nitroglycerin dosage and blood lipids were compared between two groups before and after treatment.All patients were followed up six months.Results:Compared with before treatment,there were significant reductions in angina pectoris attack frequency,duration,pain degree and nitroglycerin dosage after treatment 12 weeks in two groups,P0.05 all). Compared with before treatment,there were significant reductions in serum levels of total cholesterol [ (5.62 ± 0.54)mmol/L vs.(3.68±0.41)mmol/L,(5.78±0.56)mmol/L vs.(3.33±0.43)mmol/L],triglyceride [(2.30 ±0.42)mmol/L vs.(1.62±0.34)mmol/L,(2.35±0.41)mmol/L vs.(1.68±0.69)mmol/L]and low density lipoprotein cholesterol [(3.56±1.22)mmol/L vs.(2.76±0.83)mmol/L,(3.48±1.21)mmol/L vs.(2.43± 0.72)mmol/L],and significant increase in level of high density lipoprotein cholesterol [(1.32±0.35)mmol/L vs. (1.58±0.34)mmol/L,(1.30±0.46)mmol/L vs.(1.60±0.45)mmol/L]in atorvastatin group and simvastatin group after treatment (P0.05);there was no significant difference in incidence rate of cardiovascular events (28.00% vs.25.33%,P>0.05)between two groups during follow-up.Conclusion:Both atorvastatin and simvasta-tin can effectively regulate the state of high blood lipid,and possess good effect and safety for angina pectoris of coronary heart disease.
