Background: Hypertriglyceridemia (HTG) is associated with increased cardiovascular risk and is common in diabetes (DM); however, statin therapy remains the primary treatment in most with moderate HTG. We examined the extent of residual HTG despite statin treatment and in those with well-controlled LDL-C in adults with DM.
Methods: We studied 1,448 subjects with DM projected to 24.4 million (11.1% of U.S. adults) in the U.S. National Health and Nutrition Examination Surveys 2007-2014 who had available morning fasting triglyceride (TG) levels. We compared the distribution of TG levels by statin use.
Results: The Table shows in DM overall and by statin use the proportions with TG <150 mg/dl, 150-199 mg/dl, 200-499 mg/dl, and ≥500 mg/dl; nearly 40% despite statin use had TG ≥150 mg/dl. In addition, despite an LDL-C<100 mg/dl (<70 mg/dl in those with atherosclerotic cardiovascular disease), TG≥150 mg/dl and TG≥200 mg/dl were prevalent in 35.7% and 15.0% of statin users, respectively, and 36.2% and 17.4% of non-statin users, respectively.
Conclusions: Residual HTG despite statin use remains common in more than a third (approximately 10 million) of U.S. adults with DM, even among statin users with well-controlled LDL-C levels. Greater efforts are needed to promote adherence to lifestyle measures, as well as use of pharmacologic therapies where indicated, to address the risks associated with residual HTG.
