The risk factors for cardiovascular disease in diabetic patients are aggregated, dangerous and have a multiplicative effect with diabetes, making them at high risk for cardiovascular disease, or they are themselves at risk for cardiovascular disease (CVD). The risk of CVD in diabetic patients is two to four times higher than in those without diabetes, and for every 1% increase in HbA1c compared to those without diabetes, the risk of CVD increases two to three times in men and three to five times in women with diabetes, and the risk of stroke increases in patients with diabetes and hypoglycemia (IGT). The Finnish EAST-WEST study suggested that the prognosis for recurrent myocardial infarction in patients with diabetes was comparable to that of patients with a history of myocardial infarction over a 7-year follow-up period; in 2005, the 18-year follow-up of patients in the EAST-WEST study remained highly consistent with the results at 7 years. The UKPDS study confirmed clinical evidence of macrovascular complications in nearly 50% of newly diagnosed type 2 diabetic patients; at the same time, macrovascular complications are the most common cause of death in diabetic patients, with approximately 2/3 of diabetic patients dying from cardiovascular disease; myocardial infarction is the most common cause of death in diabetic patients, accounting for approximately 40% of all-cause deaths. Therefore, it is necessary to take a holistic view of diabetes, pay comprehensive attention to multiple risk factors, control blood glucose and actively control hypertension and blood lipids at the same time to reduce cardiovascular risk in diabetic patients, and form a comprehensive prevention and treatment strategy of multiple risk factors centered on blood glucose to centered on prevention and treatment of cardiovascular events.
