Population
72 patients evaluated one year after aortocoronary saphenous vein bypass surgery

Graft patency associates with post-bypass angina relief; supports correlation but leaves open causality and should not yet change practice.
Does anatomical success (graft patency) correlate with clinical relief of angina and treadmill performance one year after aortocoronary bypass surgery?
Complete relief of angina after coronary bypass surgery is significantly associated with higher graft patency and improved treadmill performance, although graft patency alone does not guarantee clinical relief.
Matlof et al. (1973) studied this question.
