Post-CABG stress-test gains lack identifiable predictors; leaves open routine testing to gauge functional benefit.
Does aortocoronary bypass surgery improve double product at the onset of ischemia in patients undergoing treadmill stress testing?
Treadmill stress testing reveals a disparity between symptomatic relief and functional improvement after aortocoronary bypass surgery, though baseline stress test parameters do not predict functional benefit.
Stuart et al. (1979) studied this question.
