Abstract

Labelled fatty acids have been proposed to explore cardiac metabolism. For the analysis of the external detection curve obtained with 16-iodo 9-hexadecenoic acid (IHA), we developed a mathematical 4-compartment model with compartments 0, 1, 2 and 3 representing vascular IHA, intracellular IHA, esterified forms and iodide, respectively. This model, used here for isolated rat hearts perfused in a recirculating system, is validated by an intracellular analysis, then tested in various metabolic conditions. Thus, the mathematical analysis of the external detection curve gives us numerical data on IHA metabolism, especially the distribution between degradation and storage. Our results confirm the suitability of IHA for assessing myocardial metabolism.
