Abstract: Abstract Objective: To explore the clinical significance of creatinine clearance（Ccr）and total bilirubin（TBIL）Levels in aged patients with coronary heart disease. Methods: According to coronary artery angiography (CAG), 784 subjects aged more than 65 years were divided into several groups. The creatinine clearance and total bilirubin Levels were compared. Results: With the increased number of involved branches, the level of Ccr was gradually decreased, the level of TBIL was gradually increased (P<0.05). Multi-Logistic regression analysis showed that Ccr and TBIL were independent risk factors of CHD. Conclusion: Ccr and TBIL may have clinical forecast value for CHD. It was important to improve renal and liver functions in intervention and prevention of aged patients with coronary heart disease.

Key words: coronary disease, creatinine clearance, total bilirubin, aged
