Abstract:

PURPOSE OF REVIEW: Sudden cardiac arrest is associated with high morbidity and mortality. Despite having a disproportionate burden of sudden cardiac death (SCD), rates of primary and secondary prevention of SCD with implantable cardioverter-defibrillator (ICD) therapy are lower among eligible racially minoritized patients. This review highlights the racial and ethnic disparities in ICD utilization, associated barriers to ICD care, and proposed interventions to improve equitable ICD uptake. RECENT FINDINGS: Racially minoritized populations are disproportionately eligible for ICD therapy but are less likely to see cardiac specialists, be counseled on ICD therapy, and ultimately undergo ICD implantation, fueling disparate outcomes. Racial disparities in ICD utilization are multifactorial, with contributions at the patient, provider, health system, and structural/societal level. SUMMARY: Racial and ethnic disparities have been demonstrated in preventing SCD with ICD use. Proposed strategies to mitigate these disparities must prioritize care delivery and access to care for racially minoritized patients, increase the diversification of clinical and implementation trial participants and the healthcare workforce, and center reparative justice frameworks to rectify a long history of racial injustice.
