Objective To explore the effect of applying serum bilirubin and uric acid test in the clinical diagnosis of coronary heart disease. Methods The 50 CAD patients were selected as the study subjects (observation group), and were admitted from January 2020 to December 2021. And 50 healthy patients who came to the hospital for physical examination were selected as the reference objects (control group). The hospital performed serum bilirubin and uric acid tests in both groups, and also performed coronary angiography for the patients in the observation group. The levels of serum bilirubin and uric acid test were compared between the two groups, and the influence of different severity of coronary heart disease on the levels of serum bilirubin and uric acid test was analyzed. Results The direct bilirubin level in the observation group was (4.75 ± 1.52) umoi/L, the indirect bilirubin level was (6.84 ± 1.26) umoi/L, and the total bilirubin level was (11.54 ± 4.03) umoi/L, which was lower than that in the control group (P<0.05); The uric acid level was (374.23 ± 30.18) umoi/L, which was higher than the control group (P<0.05). As the severity of the disease increases, the patients bilirubin level gradually decreases and uric acid level gradually increases. Conclusion The application of serum bilirubin and uric acid test in the clinical diagnosis of coronary heart disease is effective to confirm the lesions, and can also provide a reference for the severity of patients lesions, which is worth popularizing.
