Abstract
The well established relief of symptoms of coronary heart disease by bypass surgery is based on a number of factors among which the completeness of revascularization, patency of grafts, and progression of disease in both grafted and nongrafted arteries are most significant [1], In principle there are two alternatives in analyzing the relief of symptoms: 1) comparison of patients with patent grafts with patients having graft occlusions, and 2) the use of randomized, medically treated controls. The first alternative elucidates the role of graft patency, while the latter approach gives the overall results of bypass surgery, regardless of the mechanism of action.
