Key result
Coronary sclerosis is linked to ~47% lower myocardial palmitic acid extraction versus valvular disease.
Why the study?
Myocardial metabolism of individual free fatty acids in valvular disease compared with coronary sclerosis was not well characterized.

Myocardial free fatty acid metabolism differs between valvular disease and coronary sclerosis, with valvular disease showing a higher extraction ratio of palmitic acid.
Myocardial individual FFA metabolism was studied in valvular disease and coronary sclerosis using gas chromatography.In coronary sclerosis, the composition of palmitic and stearic acid in coronary arterial and venous blood was higher, and palmitoleic, oleic and linoleic acid was lower than that in valvular disease.Concerning the myocardial metabolism of individual FFA, the significantly higher extraction ratio of palmitic acid was found in valvular disease as compared with coronary sclerosis.

Kikuchi et al. (1966) conducted an observational in Coronary sclerosis and valvular disease (n=17). Coronary sclerosis vs. Valvular disease was evaluated on Myocardial extraction ratio of palmitic acid (p=statistically significant). Patients with coronary sclerosis had a significantly lower myocardial extraction ratio of palmitic acid (14.0%) compared to those with valvular disease (26.6%).
