Abstract 15312: Predictors for Defibrillator Therapy in Modern Urban Cohort of Patients With Heart Failure

Introduction: African Americans (AA) have been under-represented in landmark ICD trials and the impact of co-morbidities and medications on sudden cardiac death (SCD) and ventricular arrhythmias is not well established this population. Hypothesis: Risk factors for ventricular events in a predominantly AA population with heart failure who may differ from general US population. Methods: We conducted a single-center retrospective chart review. Implant, interrogation and demographics data from January 2013 to January 2018 were identified. Patients with hereditary arrhythmias and those implanted for secondary prophylaxis of SCD were excluded from the analysis. Appropriate ICD events were defined as either non-sustained ventricular arrhythmia >170 bpm, ATP therapy or shock. Results: Of 160 patients identified, 90% were AA, 59% were male and 48% had heart failure attributed to coronary artery disease. The average EF was 24.3±7.8%, average follow-up was 27.2±1.37 months. Of those 18% had appropriate ICD events an...
