Diabetic cardio-vascular complications are macrovascular complications of diabetes. In addition to elevated blood glucose, patients often have hypertension, hyperlipidemia, smoking, obesity and other risk factors, which together lead to atherosclerosis and coronary artery stenosis. Coronary stenosis in diabetic patients tends to be diffuse stenosis, mostly manifesting as three-branch lesions, which can manifest clinically as atypical angina pectoris as well as painless myocardial infarction. Cerebrovascular often manifests as multiple narrowing and obstruction of cerebral vessels with clinical manifestations of cerebral infarction and stroke. For the treatment of diabetic cardiovascular and cerebrovascular complications, a comprehensive intervention is needed to actively control blood glucose, blood pressure, adjust blood lipids, and actively administer antiplatelet drugs and plaque stabilizing drugs.
