Use of Statins Not Associated with an Increased Risk of Microvascular Disease用他汀类药物与微血管病变的风险增加无关

Use of statins before diagnosis of incident diabetes was not associated with an increased risk of microvascular disease, according to a national Danish study. The study identified all patients living in Denmark who were aged 40 years or older and were diagnosed with incident diabetes between Jan 1, 1996, and Dec 31, 2009. 15 679 individuals who had used statins regularly until their diagnosis of diabetes (statin users) were randomly selected and matched in a 1:3 ratio with 47 037 individuals who had never used statins before diagnosis (non-statin users). Data were analyzed with Cox regression models, adjusted for covariates including sex, age at diabetes diagnosis, and method of diabetes diagnosis as well as adjustments with a propensity score and with other factors. Median follow-up was 2•7 years (range 0—13). Compared with non-statin users, statin users had a lower cumulative incidence of diabetic retinopathy, diabetic neuropathy, and gangrene of the foot, but not diabetic nephropathy. A previous meta analysis suggested that intensive-dose statin therapy may be associated with an increased risk of new-onset diabetes compared with moderate-dose statin therapy.
