THE RELATIONSHIP BETWEEN DE RITIS SCORE AND RADIAL ARTERY STENOSIS IN PATIENTS UNDERGOING CORONARY ANGIOGRAPHY VIA THE TRANSRADIAL ACCESS

OBJECTIVE: While transradial access (TRA) coronary angiography (CAG) is recommended, radial artery stenosis (RAS) remains a significant issue in these patients. In patients with RAS, the reuse of the radial artery for CAG, as a coronary artery bypass graft, or as a conduit for hemodialysis fistula formation can pose a serious problem. The De Ritis score is defined as the ratio between the levels of aspartate transaminase (AST) and alanine transaminase (ALT) in the serum. Our study aimed to assess the relationship between RAS and the De Ritis score. MATERIAL AND METHODS: This retrospective study included a total of 96 patients who underwent elective CAG via the radial artery route in our hospital's catheter laboratory and were subsequently placed under medical follow-up. RESULTS: In our study, the De Ritis score was significantly higher in RAS+ patients than in the RAS- patient group (1.72 vs. 1.10; p=0.006). Multivariate logistic regression analysis demonstrated that the De Ritis score was an independent predictor of RAS (p=0.037). The De Ritis ratio predicted significant RAS with a cut-off point of 1.35, achieving a sensitivity of 70% and a specificity of 79% (AUC: 0.787, 95% CI: 0.643-0.932, p: 0.001). CONCLUSIONS: Our study identified that an elevated De Ritis score is an independent indicator of RAS.
