Abstract: Objective  To investigate the risk factors of the infarct growth rate (IGR) in patients with acute anterior circulation large vessel occlusion. Methods  This is a retrospective analysis of consecutive patients having acute anterior circulation large-vessel occlusion and being admitted to the Department of Neurointerventional Intervention, Central Hospital affiliated to Dalian University of Technology between September 2021 and July 2023. Patients were dichotomized into rapid and slow growth groups based on the median value of IGR, with 145 cases in each group. Univariate and multivariate Logistic regression models were used to analyze the risk factors of preoperative IGR. Results  Multivariable Logistic regression analysis, after univariate screening, showed that hypertension (OR=2.27, 95% CI: 1.39-3.71), atrial fibrillation (OR=1.95, 95% CI: 1.22-3.12), and intracranial internal carotid artery occlusion (OR=1.98, 95% CI: 1.19-3.28) were risk factors of preoperative IGR (P<0.05). Hypertension, atrial fibrillation, and internal carotid artery occlusion all exhibited relatively low predictive value for IGR (P<0.05). The area under the curve for predicting IGR by combining these three factors was 0.642 (95% CI: 0.579-0.704), indicating a slight improvement in predictive performance, yet it remained relatively low. Conclusion  Hypertension, atrial fibrillation, and proximal occlusion are risk factors of IGR in patients having acute anterior circulation large vessel occlusion.
