Abstract The heart has both the greatest caloric needs and the most robust oxidation of
fatty acids (FAs). Under pathological conditions such as obesity and type 2
diabetes, cardiac uptake and oxidation are not balanced and hearts accumulate
lipid potentially leading to cardiac lipotoxicity. We will first review the
pathways utilized by the heart to acquire FAs from the circulation and to store
triglyceride intracellularly. Then we will describe mouse models in which excess
lipid accumulation causes heart dysfunction and experiments performed to
alleviate this toxicity. Finally, the known relationships between heart lipid
metabolism and dysfunction in humans will be summarized.
