Official Title: Lipid Biomarkers for Diabetic Heart Disease

Brief Summary: This study will test whether lowering the delivery of excess fats to the heart in persons with type-2 diabetes mellitus improves heart muscle function. The investigators will also test whether specific lipid molecular species in plasma can serve as biomarkers for diabetic heart disease.

Detailed Summary:

Screening procedures include 12-hour fasting blood draw, urine pregnancy testing for females, completion of medical history questionnaire, and stress echocardiography to rule out coronary artery disease or cardiomyopathy.

Subjects who meet screening criteria will return for visit 2, which consists of a urine collection, 12-hour fasting blood draw, dual-energy X-ray absorptiometry (DXA) for body composition, magnetic resonance spectroscopy analysis of the liver, and resting echocardiogram for analysis of heart structure and function. Subjects will then be randomized to treatment with fenofibrate (160 mg/d) or an identical-appearing placebo for 12 weeks. They will be asked to continue their usual medications, diet and physical activity. Subjects will receive a pedometer to wear daily to track their physical activity. Subjects will meet with dietitians from the Lifestyle Intervention Core to complete a 24-hour dietary recall. They will be instructed to record their daily blood glucose concentrations, distance walked and any side effects, illnesses or stresses in a study-supplied log. Subjects will be instructed to either email or fax the log to the study coordinator each week (or discuss by phone).

Subjects will return 6 weeks after starting intervention for visit 3 to ensure their medical safety. Procedures at this visit include an interim medical history, urine pregnancy test for females, blood draw to rule out untoward effects of the study drug on liver or kidney function, pill count to assess compliance, review of logs of blood glucose, distance walked, and side effects, illnesses or stresses, and meeting with a dietitian for a 24-hour dietary recall.

Subjects will continue to take their study medication/placebo and keep logs of blood glucose levels, distance walked, and s
