Abstract Background Chronic kidney disease (CKD) increases cardiac arrest (CA) risk because of renal and cardiovascular interactions. Methods Using Centers for Disease Control and Prevention (CDC) data from 1999 to 2020, we analyzed CKD‐related CA mortality and the impact of social vulnerability index (SVI). Results We identified 336 494 CKD‐related CA deaths, with stable age‐adjusted mortality rates over time. Disparities were observed across gender, racial/ethnic, and geographic subpopulations, with higher mortality among males, Hispanic and non‐Hispanic Black populations, and those in urban and Western regions. Higher SVI correlated with increased mortality. Conclusions CKD‐related CA mortality rates are stable, with disparities across demographics; higher SVI correlates with increased mortality, highlighting needed interventions.
