AbstractThe purpose of this study was to investigate the prevalence of abnormal glucose regulation (AGR) in patients with established coronary artery disease (CAD), and the association of AGR and acute coronary events in Chinese patients.A total of 3441 hospitalized patients with established diagnosis of CAD were recruited from 41 centers in 25 cities of China. Oral glucose tolerance test (OGTT) was performed in 2112 patients without known diabetes. Acute coronary events were recorded for the patients.AGR was detected in 1880 (89%) patients in the OGTT cohort, with 1265 (59.9%) diagnosed with impaired glucose tolerance, 363 (17.2%) diagnosed with diabetes, and 30 (1.4%) diagnosed with isolated impaired fasting glucose. The overall proportion of patients diagnosed with diabetes increased from 30.7% (n = 930) at baseline to 42.6% (n = 1298) following the OGTT analysis. In total 85% (n = 3047) patients in the study was diagnosed with AGR. Multivariate analysis showed that AGR was independently associated with acute coronary events, after adjusting for the traditional risk factors including age, smoking, hypertension, and hyperlipidemia.The prevalence of AGR is increasing in Chinese patients with CAD, as compared with previous report. AGR was independently associated with acute coronary events. Prospective studies are warranted to evaluate the benefit of intervening prediabetes in adult patients with CAD.Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc.
