Vascular aging is the common pathological basis of chronic diseases such as cardiovascular and cerebrovascular diseases, and its early intervention has important public health significance. The overall regulation theory of preventive treatment of disease in traditional Chinese medicine has significant advantages in the prevention and treatment of vascular aging. However, due to the lack of systematic consensus on diagnosis and treatment, the lack of standardization in syndrome differentiation, treatment and prevention has seriously hindered the standardized clinical application and the construction of collaborative diagnosis and treatment system of traditional Chinese and Western medicine. Based on the current evidence and clinical practice, the multidisciplinary expert team developed and registered the "Expert consensus on diagnosis and treatment of vascular aging with traditional Chinese medicine (2026)" aiming to clarify the standardized formulation path of the expert consensus.
