Abstract: | Diabetes mellitus and impaired glucose tolerance are well-known risk factors for coronary artery disease (CAD) and adverse clinical events after percutaneous coronary intervention (PCI). Postprandial hyperglycemia is an important risk factor for CAD and serum 1,5-anhydroglucitol (1,5-AG) reflects postprandial hyperglycemia more robustly than hemoglobin (Hb)A1c. We aimed to clarify the relationship between serum 1,5-AG level and adverse clinical events after PCI. We enrolled 141 patients after PCI with follow-up coronary angiography. We evaluated associations between glycemic biomarkers including HbA1c and 1,5-AG and cardiovascular events during follow-up. Median serum 1,5-AG level was significantly lower in patients with any coronary revascularization and target lesion revascularization (TLR) 13.4 µg/ml (first quartile, third quartile 9.80, 18.3) vs. 18.7 (12.8, 24.2), p = 0.005; 13.4 µg/ml (10.2, 16.4) vs. 18.7 (12.9, 24.2), p = 0.001, respectively]. Multivariate logistic analysis showed lower 1,5-AG was independently associated with any coronary revascularization and TLR (odds ratio 0.93, 95 % confidence interval 0.86–0.99, p = 0.04; 0.90, 0.81–0.99, p = 0.044, respectively), whereas higher HbA1c was not. Postprandial hyperglycemia and lower 1,5-AG are important risk factors for adverse clinical events after PCI. |
