BACKGROUND: Type 2 diabetes (T2D) patients are at increased risk for cardiovascular (CV) events. Most guidelines recommend treating low-density lipoprotein cholesterol (LDL-C) levels to ≤70 mg/dL (1.8 mM) for patients with T2D and established atherosclerotic CV disease, and some a more aggressive target of ≤55 mg/dL (1.4 mM). Our objective was to assess the degree to which these LDL-C targets are achieved in routine practice. METHODS: Using data from TECOS, an international pragmatic CV outcomes trial of sitagliptin vs placebo, we assessed lipid-lowering treatment among patients with T2D and CV disease, baseline lipid values, and the association between baseline LDL-C and 5-year risk for major adverse cardiac events (MACE; ie, CV death, nonfatal myocardial infarction, or nonfatal stroke). RESULTS: Overall, 11,066 of 14,671 TECOS participants (75.4%) had LDL-C measured at baseline. Median age was 65 years, 72% were male, and median T2D duration was 10 years. Overall, 82.5% of patients were on statins; only 5.8% were on ezetimibe. At baseline, 14.3% had LDL-C ≤55 mg/dL, 18.4% between 55.1 and 70 mg/dL, 35% between 70.1 and 100 mg/dL, and 32.3% >100 mg/dL. Each 10 mg/dL higher LDL-C value was associated with a higher risk of MACE (HR 1.05, 95% CI 1.03-1.07) or CV death (HR 1.06, 95% CI 1.04-1.09). CONCLUSIONS: Although most high-risk patients with T2D and CV disease were on lipid-lowering therapy, only 1:3 had LDL-C
