大血管病变在糖耐量受损(IGT)阶段就已经存在。流行病学显示糖耐量受损(IGT)患者是2型糖尿病和心血管疾病的高风险人群。但由于(IGT)患者基本没有临床症状,常被忽视和漏诊,致糖尿病和心血管事件的发病率持续增长。因此,早发现IGT患者及早对其进行干预,对有效预防糖尿病和延缓心血管疾病的发生具有极其重要的意义。 Macrovascular disease is already present at the stage of impaired glucose tolerance (IGT). Epidemiology shows that patients with Impaired Glucose Tolerance (IGT) are at high risk of type 2 diabetes and cardiovascular disease. However, due to (IGT) patients with almost no clinical symptoms, often overlooked and missed diagnosis, the incidence of diabetes and cardiovascular events continued to grow. Therefore, early detection of IGT patients intervened as early as possible, is effective in preventing diabetes and delaying the occurrence of cardiovascular disease is extremely important.
