title: Does Exercise Improve Coronary Collateralization? A New Look at an Old Belief.
abstract: In brief: An alternative route for blood supply in the heart-ie, coronary collateral vessels-can save the life of a person with coronary artery disease. Debate continues as to whether exercise training accelerates the growth of collateral vessels. Animal research has produced positive results, but studies of humans have been disappointing, largely because of problems in experimental design and methodology. Advances in technology-such as further refinements in radionuclide exercise testing methods-may help provide answers to this intriguing question.
