Key role of postprandial hyperglycemia for the presence and extent of coronary atherosclerosis

Background/Aims: The coronary angiographic state of patients with abnormal glucose tolerance is unclear. Methods: We enrolled 1040 consecutive patients undergoing coronary angiography for the evaluation of coronary artery disease (CAD). An oral glucose tolerance test was performed in patients without established diabetes. Results: From our patients, 394 had normal glucose tolerance (NGT), 190 impaired glucose tolerance (IGT), 90 isolated postprandial diabetes (postprandial glucose ≥200mg/dl), and 366 type 2 diabetes previously established or newly diagnosed on the basis of fasting glucose (conventional diabetes)…
