Aging is associated with decreases in myocardial fatty acid oxidation and carnitine concentration. The purpose of this study was to investigate the effects of dietary carnitine manipulation on myocardial palmitate oxidation and carnitine content in young adult and middle-aged rats. Rats were fed either a carnitine-free or a carnitine-supplemented diet for nine weeks and killed at ages 6.5 and 18 months. Myocardial carnitine content was unaffected by age or diet. However, in 18 months rats fed a carnitine-free diet, myocardial palmitate oxidation was 77% higher, carnitine palmitoyltransferase activity 39% higher, and lipid droplet volume density 55% higher compared to 18 month rats fed a carnitine-supplemented diet. In 6.5 month rats, dietary carnitine had no effect on these variables. These results indicate that dietary carnitine restriction increases myocardial fatty acid metabolism in middle-aged but not in young adult rats.
