High-intensity exercise may worsen ischemia-induced dysfunction in canine stenosis; hypothesis-generating for human CAD exercise intensity.
Does high-intensity exercise compared to low-intensity exercise worsen regional dysfunction during and after exercise-induced ischemia in a canine model?
In a canine model of coronary stenosis, high-intensity exercise resulted in greater subendocardial hypoperfusion and regional dysfunction both during and after exercise compared to low-intensity exercise.
Homans et al. (1991) studied this question.
