Abstract：Objective: To explore the influencing factors and predictive value of sudden cardiac death (SCD) in elderly patients with arrhythmogenic dilated cardiomyopathy (AR-DCM). Methods: A total of AR-DCM patients diagnosed at our hospital from January 2022 to January 2025 were selected as the subjects of this study, and divided into non-SCD group (n=142) and SCD group (n=52) based on whether SCD occurred. Univariate analysis was performed on patients' clinical data, tests, and electrocardiographic examination data; Spearman correlation analysis was used to assess the correlation between each indicator and the occurrence of SCD; multivariate binary Logistic regression analysis was conducted to identify the influencing factors of SCD in elderly AR-DCM patients; and ROC curve analysis was used to evaluate the predictive value of the relevant indicators. Results: The proportion of NYHA Class Ⅲ and Ⅳ in elderly AR-DCM patients with SCD, as well as the levels of cTnT and NT-proBNP, and the duration of Tp-Te and Tc were higher in patients without SCD (P<0.05), but only the level of NT-proBNP was an independent influencing factor (P<0.05), and had a high predictive value (AUC=0.965). Conclusion: The level of NT-proBNP is an independent influencing factor for the occurrence of SCD and has the best predictive value.
