EFFECTS OF COMPONENTS OF MEALS (CARBOHYDRATE, FAT, PROTEIN) IN CAUSING POSTPRANDIAL EXERTIONAL ANGINA-PECTORIS

We have shown that unlike fat, protein, xylose, or water, the carbohyd rate component of the meal accelerates myocardial ischemia, reduces ex ercise capacity, and is associated with a more rapid increase in the d eterminants of myocardial oxygen consumption than exercise in the fast ing state. Our results suggest a role for a larger increase in sympath etic nervous activity and/or release of vasoactive gastrointestinal pe ptides after carbohydrate, but not fat or protein, meals in postprandi al angina.
