Collateral vessels confer only partial ischemic protection under stress in dogs; leaves open translation to human chronic coronary disease.
What is the functional capacity of coronary collateral circulation under resting and stress conditions in dogs with chronic coronary occlusion?
Coronary collateral vessels in dogs play a beneficial role in preventing ischemic injury under stress, though their functional capacity is less than that of normal coronary arteries.
Katada et al. (1980) studied this question.
