简要总结
At present, it is recognized that statins are the cornerstone of treatment for the prevention of major cardiovascular events in patients with atherosclerotic cardiovascular disease (ASCVD); However, at the same time, the increased risk of long-term glucose tolerance and type 2 diabetes mellitus caused by statin therapy has attracted wide attention. The investigators' recent study found that the levels of glycosylated hemoglobin, insulin and C-peptide increased significantly with the extension of follow-up time in patients with hyperlipidemia. At the same time, serum and fecal bile acid metabolism profiles, especially secondary bile acid metabolism, were extensively changed, especially in ursodeoxycholic acid (UDCA), suggesting that the decrease of UDCA is a possible mechanism for statins to induce side effects of diabetes. According to this hypothesis, ursodeoxycholic acid combined with statins may improve the abnormal glucose tolerance caused by statins and maximize the benefit of statins. This study is a multicenter, prospective, randomized, parallel, double-blind placebo-controlled, cohort study. Taking ASCVD patients as the research object, the investigators will compare the changes of glycosylated hemoglobin, fasting blood glucose, fasting insulin, C-peptide and metabolomic indexes before and after the use of ursodeoxycholic acid combined with atorvastatin and atorvastatin alone and during follow-up, Further evaluate the changes of blood glucose related indexes before and after the use of ursodeoxycholic acid combined with atorvastatin and atorvastatin alone, clarify the possible mechanism and specific treatment targets of abnormal glucose tolerance caused by statin, and put forward a possible alternative treatment for the disorder of glucose metabolism caused by statin.
