Diabetic patients must pay attention to two “early” to deal with coronary heart disease, one is early detection, the second is early prevention. To prevent the occurrence of coronary heart disease is to do three standards and follow two recommendations. The three standards are the basic blood sugar, blood pressure and blood lipid standards in diabetes treatment. Striving to meet the blood glucose standard is a daily necessity for diabetic patients, while effective control of postprandial blood glucose has an important value in reducing and delaying the occurrence and development of diabetic cardiovascular complications, so we should never forget to pay attention to postprandial blood glucose in our daily blood glucose treatment and monitoring. About one-third of diabetic patients have hypertension, and the goal of blood pressure attainment is systolic blood pressure.
