This study used the diabetes prevention and follow-up research queue in Daqing and the public database of UKbiobank to evaluate the risk factors of cardiovascular and cerebrovascular events in diabetes patients, and built the first risk prediction model of cardiovascular and cerebrovascular events in diabetes patients based on the Chinese population follow-up queue and externally verified, so as to identify high-risk groups and guide the early prevention of cardiovascular and cerebrovascular diseases in diabetes patients. To evaluate the effect of incretin drugs on reducing the risk of cardiovascular and cerebrovascular events, and the impact on the remission rate of diabetes in people with initial diabetes, a randomized, multicenter, controlled clinical study was conducted. The long-term follow-up of 2 years was conducted to evaluate whether the cardiovascular and cerebrovascular risks of those who stopped drug treatment after remission of diabetes compared with those who continued drug treatment were reduced, as well as the long-term impact of incretin on cardiovascular and cerebrovascular risks and the role of long-term mitigation of diabetes.
