Abstract:
Objective To analyze the relationship between the concentration of plasma insulin during oral glucose tolerance test (OGTT) and stent restenosis in non-diabetic patients, and determine whether hyperinsulinemia during OGTT is a predictor of the development of stent restenosis. Methods 49 non-diabetic patients with coronary artery disease underwent stent implantation were enrolled in this study. All patients were subjected to 75g OGTT before or after stent implantation, and coronary angiography was performed to observe the stent restenosis about 6 months of post-operation. Results The concentrations of plasma insulin at 0 5, 1, 2 and 3 hours after glucose loading were significantly higher in patients with stent restenosis than those in patients without stent restenosis(P≤0 05). Insulin area(IA) and insulin area/glucose area(IA/GA) were also significantly higher in patients with stent restenosis than those in patients without stent restenosis(P≤0 05). Conclusion Non-diabetic patients with hyperinsulinemia during OGTT had a higher risk for stent restenosis after stent implantation, and OGTT before stent implantation may be useful to predict stent restenosis.
