Why the study?
Do meals of differing composition (carbohydrate, fat, balanced) reduce exercise tolerance in patients with chronic stable angina?
Population
14 patients with chronic stable angina, mean age 61 (range 41-73) years.
Comparison
Approximately isocalorific liquid drinks of 600… vs Equal volume of water ingested 1 hour before…
Design
RCT, Meals were given in random order
Follow-up
1 hour post-ingestion

Carbohydrate-rich meals warrant pre-exercise caution in stable angina; extends postprandial ischemia evidence to macronutrient composition.
Do meals of differing composition (carbohydrate, fat, balanced) reduce exercise tolerance in patients with chronic stable angina?
High-calorie liquid meals, especially those rich in carbohydrates, significantly impair effort tolerance and lower the angina threshold in patients with chronic stable angina, suggesting patients should avoid exercise shortly after eating.
Lam et al. (1996) studied this question.
