Summary

Diabetes is a leading social and economic burden in the world. It is the main reason of macrovascular disease incidence and mortality. Prospective studies have demonstrated that high glycosylated hemoglobin (HbA1C) levels are associated with an increased risk of cardiovascular events in a population of diabetic patients without a history of coronary artery disease. Further, the predictive value of high preprocedural glycemia levels has been reported in diabetic patients undergoing percutaneous coronary intervention (PCI). The aim of the present study was to assess the predictive value of preprocedural HbA1C levels for cardiovascular complications in a large population of diabetic patients undergoing PCI with stent implantation. Glycosylated hemoglobin (HbA1c) reflects the average blood sugar level in the past 2-3 months. As glycosylated hemoglobin has been clinically tested and standardized internationally, increasing evidence is recommended for routine monitoring in diabetes care. The American Diabetes Association (ADA) suggested that in the treatment of diabetes, blood sugar control should control HbA1c level below 6.5%. Although，there is evidence that controlling blood glucose can reduce the incidence of microvascular complications, in the past three trials, intensive glycemic control did not significantly reduce adverse CV events in patients with onger duration of diabetes.Therefore, most primary and secondary prevention guidelines recommend HbA1c below 6.5% or 7% to prevent adverse cardiovascular outcomes in patients with diabetes mellitus. The optimal target level of glycosylated hemoglobin is still hotly debated. In addition, there is still lack of evidence for the level of HbA1c in patients with major vascular disease history in secondary prevention of recurrence cardiovascular events. Therefore, to explore and determine the optimal level of blood glucose control is the focus of controversy in preventing recurrence cardiovascular events in diabetic patients. Investigator will combine epidemiology and metabolomics to study the effect of glycosylated hemoglobin on secondary cardiovascular events, and further determine whether to strengthen hypoglycemic treatment after PCI.
