Coronary heart disease(CHD)，characterized by atherosclerosis of the coronary arteries，is the leading cause of cardiovascular disease-related deaths and represents a major public health problem in China and globally.Current medical research has found an association between CHD and chronic kidney disease(CKD).Many common indicators of CKD are independent risk factors for the occurrence and progression of CHD.Controlling the progression of kidney disease may offer a new approach to preventing and treating CHD.Integrated traditional Chinese medicine(TCM) and Western medicine has demonstrated effective outcomes in the prevention and treatment of CHD.In TCM，the physiological connection and pathological similarities between the heart and kidneys are recognized.With changes in social lifestyles，the TCM syndromes associated with CHD have evolved beyond blood stasis syndrome to include combinations such as “kidney deficiency and blood stasis syndrome” which have become important diagnostic indicators in the formation of CHD.This study aims to review and explore the theoretical origins and clinical applications of the TCM syndrome of kidney deficiency and blood stasis in CHD，providing a theoretical basis for enhancing the level of TCM in the prevention and treatment of CHD.
