Background: Atrial fibrillation (AF) is the most common arrhythmia in the adult population and causes a significant increase in the risk of thromboembolism. The ATRIA risk scoring system was developed to assess the risk of thromboembolism in AF patients. In our study, we aimed to investigate the relationship between the ATRIA risk score and the C-reactive peptide (CRP)/Albumin ratio in patients with AF. Materials and Methods: 240 patients with non-valvular AF between December 2015 and December 2021 were included in our study. ATRIA scores were calculated by retrospectively scanning the clinical information and examination results of the patients from the hospital information system. Results: 240 patients were included in the study. The mean age of the patients was 67.35±9.5, and 42.9% were male. 27.9% of the patients had diabetes mellitus, 44.2% had hypertension, 24.2% had hyperlipidemia and 32.1% had coronary artery disease. According to the ATRIA score, the high-risk group was found to have higher glucose, creatinine, CRP and CRP/Albumin ratios. In the correlation analysis, a positive correlation was found between the ATRIA score and the CRP/Albumin ratio (r=0.687; p=0.001; p<0.01). In multivariate logistic regression analysis, age, CRP, CRP/Albumin ratio, diabetes, and hypertension were found to be independent predictors of the ATRIA score. In Roc analysis, the area under the curve was found to be 0.964 for the platelet lymphocyte ratio (0.941-0.988, p<0.001), the cutoff value for which the CRP/Albumin ratio predicted a high ATRIA score was 0.093 with a sensitivity of 93.8% and a specificity of 93.1%. Conclusion: CRP and albumin levels are parameters that can be easily measured in the blood. In our study, it was found that the CRP/Albumin ratio correlated with the ATRIA risk score. We believe that the ATRIA risk score can be used in addition to the other scoring systems in the determination of the risky group in terms of thromboembolism in AF patients.
