Modulation of Free Fatty Acids in Heart Failure Patients With Diabetes: "Effect on Left Ventricular Function"

Short Term Modulation of Circulating Free Fatty Acids in Heart Failure Patients With Type 2 Diabetes: "Effect on Myocardial Lipid Content, Left Ventricular Function and Exercise Capacity"

The investigators wish to investigate the the short term effect of low circulating free fatty acids in congestive heart failure patients with type 2 diabetes.

Hypothesis: Low levels of circulating free fatty acids decrease myocardial and peripheral muscle lipid content, improves cardiac performance and exercise capacity.

• type 2 diabetes

Exclusion Criteria:

• known s-creatinine >220mM
• known S-alanine aminotransferase >3 times normal upper limit
