What is the significance and the mechanism of postprandial angina ?
The presence of postprandial angina indicates severe coronary artery disease; one mechanism is 'intramyocardial steal' with blood being distributed from the stenotic territories to the normal territories (Circulation 1998; 97: 1144-9). It results from the carbohydrate content of the meal (Am J Cardio/ 1997;79: 1397-1400) and can be ameliorated by prior treatment with octreotide (Circulation 1996; 94: 1-730), which prevents postprandial vasodilatation of the superior mesenteric artery.
