糖尿病是一种危害严重的常见慢性代谢性疾病。尽管胰岛素和抗生素广泛应用于临床以来,糖尿病人的急性并发症死亡率明显下降,但其慢性血管损害尤其是心血管病变则成为日益突出的健康威胁。据美国Joslin研究所报告,在40岁以上的糖尿病人中,心血管病占其全部死亡原因的70～73%,其中冠心病又占全部死因的51～56%。因此研究糖尿病人心血管病变的 Diabetes is a serious and chronic common metabolic disease. Although insulin and antibiotics have been widely used clinically, the mortality rate of acute complications in diabetic patients decreased significantly, but their chronic vascular damage, especially cardiovascular disease, has become an increasingly prominent health threat. According to the report of the Joslin Institute in the United States, cardiovascular disease accounts for 70-73% of all causes of death in people over 40 years old, of which coronary heart disease accounts for 51-56% of all causes of death. Therefore, the study of diabetic patients with cardiovascular disease
