Abstract：Objective: To investigate the correlation between uric acid albumin ratio (UAR) and coronary slow flow (CSF) and evaluate the predictive value of UAR for CSF. Methods: A retrospective analysis was conducted on 610 patients with chest pain who underwent coronary angiography at the Heart Center of Xinjiang Medical University. Electronic medical records and coronary angiography results were collected, and patients were grouped according to the presence or absence of CSF. Multivariable-adjusted methods were used to assess the correlation between uric acid (UA), albumin (ALB), and UAR and the occurrence of CSF. ROC curves and RCS curves were used to evaluate the relationship between the above indicators and CSF risk. Results: Compared with the control group, the CSF group had a higher proportion of males and higher rates of smoking and alcohol consumption. The CSF group had higher body mass index (BMI), hemoglobin (Hb), aspartate aminotransferase (AST), UA, and UAR levels, and lower ALB levels (P<0.05).Multivariable-adjusted logistic regression analysis showed that high UA levels (OR: 1.010, 95%CI: 1.007-1.013, P<0.001), UAR (OR: 1.513, 95%CI: 1.341-1.707, P<0.001), and low ALB levels (OR: 0.794, 95%CI: 0.733-0.860, P<0.001) were independent risk factors for CSF.ROC curve analysis showed that UA, ALB, and UAR all had good predictive value for CSF, among which UAR had the best performance (P<0.05).RCS curve analysis showed that UAR and CSF risk were generally positively correlated. Conclusion: The results suggest that UAR is associated with CSF and may be a useful biomarker for predicting CSF.
