Diabetes diagnosed by either FPG or 2h criteria are risk factor for CVD disease, but 2h criteria identify those who are not diabetic by FPG alone ? IGT is over IFG with regard to the prediction of the CVD ? More trials are required to show that intensive treatment of postprandial hyperglycemia can reduce the CVD RCT Metaanalysis: G Lowering Type 1 Diabetes Trials Am Heart J 2022。 26:29102914 Effect of intensive glycemic control on the risk for any type of macrovascular events C Stettler, Am Heart J 2022。 47: 385394 Nondiabetic Diabetic Followup Baseline 2hPG NGT IGT Nondiabetic CHD incidence CVD mortality Allcause mortality Incidence density (no./per 1000 personyears) Qiao et al.
