AbstractIntroductionIn patients with cardiac sarcoidosis (CS), implantable cardioverter‐defibrillators (ICDs) are important for preventing sudden cardiac death. This study aimed to investigate sex disparities in CS patients undergoing ICD implantation.MethodsThe 2016–2020 National Inpatient Sample (NIS) database compared the characteristics and outcomes of males and females with CS receiving ICDs.ResultsAmong 760 CS patients who underwent inpatient ICD implantation, 66.4% were male. Males were younger (55.0 vs. 56.9 years, p < .01), had higher rates of diabetes (31.7% vs. 21.6%, p < .01) and chronic kidney disease (CKD) (16.8% vs. 7.8%, p < .01) but lower prevalence of atrial fibrillation (AF) (11.9% vs. 23.5%, p < .01), sick sinus syndrome (4.0% vs. 7.8%, p = .024), ventricular fibrillation (VF) (9.9% vs. 15.7%, p = .02), and black ancestry (31.9% vs. 58.0%, p < .01). Unadjusted major adverse cardiovascular events (MACE), defined as a composite of in‐hospital death, myocardial infarction (MI), and ischemic stroke, was higher in females (11.8% vs. 6.9%, p = .024), but when adjusted for age and tCharlson Comorbidity Index (CCI), females demonstrated significantly lower odds of experiencing MACE (aOR: 0.048, 95% CI: 0.006–0.395, p = .005). Incidence of acute kidney injury (AKI) post‐ICD was significantly lower in females (15.7% vs. 23.8%, p = .01) as was the adjusted odds (aOR: 0.282, 95% CI: 0.146–0.546, p < .01). There was comparable mean length of stay and hospital charges.ConclusionICD utilization in CS patients is more common among males, who have a higher prevalence of diabetes and CKD but a lower prevalence of AF, sick sinus syndrome, and VF. Adjusted MACE and AKI were significantly lower in females.
