As compared with balloon angioplasty, stenting of selected venous bypass-graft lesions resulted in superior procedural outcomes, a larger gain in luminal diameter, and a reduction in major cardiac events. However, there was no significant benefit in the rate of angiographic restenosis, which was the primary end point of the study.

Coronary angioplasty in diabetics is associated with high success and low complication rates. Although long-term survival is acceptable, diabetics have a higher rate of infarction and a greater need for additional revascularization procedures, probably because of early restenosis and late progression of coronary disease. The most appropriate treatment for these patients remains to be determined.
