  • Title: Targets for modulation of fatty acid oxidation in the heart.
    Author: Lopaschuk GD.
    Journal: Curr Opin Investig Drugs; 2004 Mar; 5(3):290-4. PubMed ID: 15083595.
    Abstract:
    Fatty acids are a major source of fuel used by the heart to provide large amounts of energy necessary to sustain contractile function. In the healthy heart, a balance between fatty acid and carbohydrate use ensures that energy supply to the heart matches demand. However, myocardial ischemia causes profound changes in metabolism, including alterations in glucose and fatty acid metabolism that can lead to excessive myocardial fatty acid oxidation, which occurs at the expense of glucose oxidation. This contributes to cellular acidosis, a decrease in cardiac efficiency and contractile dysfunction in the ischemic heart. Inhibition of fatty acid oxidation has recently emerged as a promising approach to the prevention of these adverse effects of fatty acids. As a result, a number of key enzymes involved in the metabolism of fatty acids are potential targets for therapeutic intervention in myocardial ischemia. This includes inhibition of fatty acid uptake into the myocyte, inhibition of mitochondrial fatty acid uptake and direct inhibition of fatty acid beta-oxidation. This review describes these potential targets for modulation of energy metabolism in the heart.
