Objectives of Study: |
Based on the real-world background, a study named Integrated Traditional Chinese and Western Medicine Cohort Study and Intelligent Risk Early-Warning System Construction of Diabetic Lower Extremity Arterial Disease will be conducted. This study aimed to identify the risk factors and protective factors closely related to the disease progression of DLEAD, explore the distribution characteristics and evolution patterns of TCM syndromes at different stages of DLEAD, analyze the correlation between different exposure factors and the disease progression, and explore the advantages of TCM intervention. By combining modern data analysis techniques, early warning and risk assessment for DLEAD will be achieved, which is going to provide scientific basis and practical references for clinical disease prevention and treatment, and offere new ideas and directions for the improvement of the diabetes' comprehensive management model. |
