BackgroundCardiovascular diseases are the first cause of mortality in patients with diabetes, and LDL-cholesterol is a well-established cardiovascular risk factor. This study aimed to assess rate of LDL-cholesterol target attainment among patients with diabetes at very-high cardiovascular risk treated with statins, and to identify predictive factors of non-attainment of target in this population. MethodsPatients were recruited in the Nutrition-Diabetes unit of Montpellier University Hospital, France, from 2014 to 2017. We included all consecutive patients with type 1 or type 2 diabetes receiving statin treatment and at very-high cardiovascular risk according to 2016 ESC guidelines, therefore having a LDL-cholesterol target of <1.8 mmol/L. LDL-cholesterol levels were measured upon admission. Variables independently associated with non-attainment of LDL-Cholesterol target were assessed using multivariable logistic regression. Results654 patients were included. Mean age was 63.8 years (SD 11.0), 41.9% were women and 42.3% had a history of cardiovascular disease. 59% of patients did not achieve LDL-cholesterol target, with a median value (interquartile range) of 2.4 mmol/L (2.1–2.9) versus 1.4 mmol/L (1.1–1.6) in patients at target. Risk of non-attainment of LDL-cholesterol target value was increased in women (odds ratio [95% confidence interval]: 2.27 [1.62–3.17]) and decreased in patients with history of coronary artery disease (0.64 [0.45–0.89]) or history of stroke or transient ischemic attack (0.59 [0.33–1.07]). ConclusionsManagement of dyslipidemia is suboptimal, even in very-high risk patients with diabetes under statins. Lipid-lowering treatment should be intensified, in particular in very high risk patients with diabetes who are women or in primary cardiovascular prevention.Clinical Trial number: NCT03449784
