Achieving Lipid Targets in Adults With Type 2 Diabetes: The Stop Atherosclerosis in Native Diabetics Study

J Clin Lipidol. Sep-Oct 2010;4(5):435-43. doi: 10.1016/j.jacl.2010.07.007.

Abstract

Background: Although lipid management in diabetes is standard practice, goals often are neither met nor maintained. Strategies for achieving lower targets have not been explored. The Stop Atherosclerosis in Native Diabetics Study randomized patients with diabetes to standard versus aggressive lipid and blood pressure goals for 36 months.

Objective: To report strategies used to achieve and maintain lipid goals and to report adverse events (AEs).

Methods: Adults with type 2 diabetes and no history of cardiovascular disease (N = 499) were randomized to standard (low-density lipoprotein cholesterol [LDL-C] ≤ 100 mg/dL, non-high-density lipoprotein cholesterol [non-HDL-C] ≤ 130 mg/dL) or aggressive (LDL-C ≤ 70 mg/dL, non-HDL-C ≤ 100 mg/dL) targets. An algorithm was started with statin monotherapy, with intestinally acting agents added as required to reach LDL-C targets.Triglyceride [TG]-lowering agents were next used to reach non-HDL-C goals. Lipid management was performed by mid-level practitioners, with physician consultation, by the use of point-of-care lipid determinations.

Results: On average, both groups achieved the LDL-C and non-HDL-C goals within 12 months and maintained them throughout the study. At 36 months, mean (SD) LDL-C and non-HDL-C were 72 (24) and 102 (29) mg/dL in the aggressive group (AGG) and 104 (20) and 138 (26) mg/dL, respectively, in the standard group (STD); systolic blood pressure targets were 115 and 130 mmHg, respectively. A total of 68% of participants reached target LDL-C for greater than 50% of the visits and 46% for greater than 75% of visits. At 36 months, the AGG averaged 1.5 lipid lowering medications and the STD 1.2. Statins were used in 91% and 68% of the AGG and STD; ezetimibe by 31% and 10%; fibrates by 8% and 18%. No serious AEs were observed; AEs occurred in 18% of the AGG and 14% of the STD.

Conclusion: Standard and aggressive lipid targets can be safely maintained in diabetic patients. Standardized algorithms, point-of-care lipid testing, and nonphysician providers facilitate care delivery.
