The close relationship between diabetes and cardiovascular disease has received increasingly widespread attention. Diabetes is a high prevalence of cardiovascular disease, and cardiovascular disease is the leading cause of death from diabetes. Diabetes mellitus and cardiovascular disease are at high risk for each other and are causally symbiotic diseases. It can also be said that “diabetes and cardiovascular disease are the manifestation of the same pathological changes in different organs”, this view has been agreed, and this pathological change is the atherosclerosis that we will talk about every day. And atherosclerosis causes the culprit of various vascular events. We all know that with the development of the economy and the improvement of people’s living standards, the incidence of hypertension, dyslipidemia, diabetes, overweight and obesity in the population has increased at the same time, but the control rate is extremely low, the control rate of blood lipids is only 50%, and only 25% of diabetic patients with HbA1c meet the standard (<6.5%). The smoking rate in men is as high as 66.0%. The outlook for cardiovascular risk factor control in our population is not bright. Therefore, atherosclerotic vascular events will be a huge medical and economic burden for us. It also suggests that we have a long way to go in the prevention and control of cardiovascular diseases. Therefore, it is the joint responsibility of cardiovascular doctors and endocrinologists to promote the prevention and control of atherosclerotic diseases, to improve our understanding of primary prevention of these diseases, and to apply primary prevention treatment measures in a rational and standardized manner.
