Accumulation of lipid in skeletal and cardiac muscle has been associated with insulin resistance and diabetic cardiomyopathy. In skeletal muscle, lipotoxic damage has been suggested to lead to dysfunction of mitochondria. It remains unknown whether lipotoxicity leads to mitochondrial dysfunction in heart as well, and if so, whether this also leads to cardiomyopathy (failure of the heart). Although it has been shown that lipid lowering agents can improve insulin sensitivity, the effect of lowering free fatty acids on cardiac and skeletal muscle mitochondrial function remains unknown. In this study the investigators want to investigate whether lowering cardiac and muscular lipid content will improve mitochondrial and cellular function in type 2 diabetic patients.
