Abstract
Resume full activity and were individually managed in a 10-week “at home” exercise program. Increases were demonstrated for predicted oxygen uptake and work load (p<.002), and rate pressure product (p<.02) following CBS, suggesting increased myocardial blood flow. Terminal heart rate showed no significant increase. Of 16 patients exhibiting ST segment depression (≥.1 mV) with AP during G$T before surgery, 10 cases experienced total relief of both of these signs after surgery. A correlation between the pre-operative number of occluded coronary arteries (>50%) and the degree of exercise induced ST segment depression revealed no significant trend. Additionally, no significant relationship was found between post-operative G$T results and the number of by-pass grafts performed on each patient. This study supports the premise that the effectiveness of CBS, in improving functional capacity, can be objectively evaluated by a non-invasive functional GXT. ©1977The American College of Sports Medicine...
