Brief summary
Double-dose statin regimen achieves merely 6% of decrease in low-density lipoprotein cholesterol (LDL-C) levels, whereas the risk of side effects increased largely. The investigators' previous pilot study (NCT01686451) has suggested that red yeast rice was of similar lipid-lowering efficacy while was associated with less fatigue than statins. The purpose of this study is to evaluate the efficacy and safety of combined therapy with red yeast rice and low-dose atorvastatin in persons with mild atherosclerotic cardiovascular disease and who qualified for statin therapy according to national guidelines.
Detailed description
Both Red Yeast Rice and Statins are cholesterol-lowering medications are often prescribed for secondary prevention of cardiovascular disease (CVD). The investigators' previous pilot study (NCT01686451) has suggested that red yeast rice was of similar lipid-lowering efficacy while was associated with less fatigue than statins. The aim of this study is to compare the efficacy and safety of combined therapy with red yeast rice at 1.2 g/day and atorvastatin at 10 mg/day with atorvastatin at 20 mg/day in persons with mild atherosclerotic cardiovascular disease and who qualified for statin therapy according to national guidelines. This study will enroll individuals with established mild atherosclerotic cardiovascular disease and who do not currently take lipid-lowering medications. Participants will be randomly assigned to receive combined therapy with red yeast rice at 1.2 g/day and atorvastatin at 10 mg/day or atorvastatin at 20 mg/day for 24 weeks. Study visits will occur at screening, baseline, week 4, week 8, week 16, and week 24. Blood will be collected for laboratory testing, and standardized questionnaires will assess noncardiovascular endpoints. Pill count will be used to assess adherence of treatment. Medication side effects will be monitored and tests of alanine aminotransferase (ALT), aspartate aminotransaminase (AST) and creatine phosphate kinase (CPK) will be performed. Medication efficacy will be assessed and test of low-density lipoprotein cholesterol (LDL-C) will be performed.
Interventions
Participants will receive 2 capsules of 300mg red yeast rice and 2 capsules of 10mg atorvastatin for 24 weeks.
Participants will receive 2 capsules of placebo and 2 capsules of 10mg atorvastatin for 24 weeks.
