Abstract
We examined whether impaired coronary flow reserve in healthy men is associ ated with changes in cardiac performance and exercise-induced ischemia. A c omparison between 7 asymptomatic men with low flow reserve (<3.5) and 8 men with normal flow reserve (>3.5) showed no differences in these parameters, suggesting that. the mechanisms that control myocardial blood flow during exercise remain normal despite the alterations in the mechanisms that contr ol the vasodilatory reaction to dipyridamole.
