Abstract 18086: Psychometric Testing and Shocks in Patients with Implantable Cardioverter Defibrillators
Background Emotional stress and anxiety have been reported to be triggers for arrhythmias causing ICD shocks. We aimed to determine whether psychometric parameters are associated with ICD shocks.
Methods In a prospective cross sectional study, consecutive patients with ICDs were surveyed assessing demographics, medical history, and psychometric parameters (Beck Anxiety Inventory [BAI], Generalized Anxiety Disorder scale [GAD7], PHQ-9 depression scale, Florida Shock Anxiety Scale [FSAS], Florida Patient Acceptance Survey [FPAS], and DS14 [social inhibition, negative affectivity]). Actual and perceived ICD shock totals and type were determined.
Results Among 704 patients enrolled, 35.6% had at least mild anxiety. Total shocks (p=0.025), recent shocks (p=0.011), appropriate shocks (p=0.034), and patient reported shocks (p<0.001) were associated with anxiety (BAI), but not depression (PHQ-9). Appropriate shocks were also associated with fear about shocks (FSAS, p<0.001), and patient ICD acceptance (FPAS, p=0.015). Inappropriate shocks was not associated with anxiety (BAI, p=0.14), depression (PHQ-9, p=0.96), or patient ICD acceptance (FPAS, p=0.16). Patients with recent shocks were socially inhibited (DS-14SI, p=0.032) and had higher levels of anxiety (BAI, p=0.017).
Conclusions Total, appropriate, and recent ICD shocks were significantly associated with anxiety; recent shocks were associated with social inhibition. However, inappropriate shocks are not are not associated with anxiety and did not influence patients acceptance of ICD therapy.
