Key role of postchallenge hyperglycemia for the presence and extent of coronary atherosclerosis: an angiographic study.

Background: The associations between impaired glucose tolerance (IGT) and postchallenge diabetes with the presence and extent of angiographically characterized coronary atherosclerosis are unclear.

Materials And Methods: We enrolled 1040 consecutive Caucasian patients undergoing coronary angiography for the evaluation of coronary artery disease (CAD). An oral 75-g glucose tolerance test was performed in patients without previously diagnosed diabetes.
