Shock-related anxiety from heart devices is associated with sexual dysfunction in young adults

202

A new study shows young adults with congenital heart disease also living with an implantable cardioverter- defibrillator (ICD) experience a high level of shock-related anxiety. The multicentre study, published in the June edition of HeartRhythm, is the first to discover that shock-related anxiety is associated with sexual dysfunction in young adults and calls on healthcare providers to address these issues to improve the quality of life for patients.

Patients in this study, lead by Stephen Cook, Adult Congenital Heart Disease Center, Heart Institute, Children’s Hospital of Pittsburgh of University of Pittsburgh Medical Center, USA, were prospectively enrolled from four adult congenital heart disease outpatient clinics within the Alliance for Adult Research in Congenital Cardiology. The Florida Shock Anxiety Scale (FSAS), a 10-item tool designed to provide a quantitative measure about the ability to cope with the impact of a shock, was administered to patients with an ICD. Men completed the Sexual Health Inventory for Men (SHIM), a questionnaire for screening and diagnosing erectile dysfunction and its severity. Additionally, women completed the Female Sexual Function Index (FSFI), a self-report questionnaire that assesses sexual function in women in a variety of dimensions.

A total of 180 patients (70 patients with an ICD, 110 patients without an ICD) and an average age of 32 years old were enrolled in the study. In ICD recipients, a high level of shock-related anxiety was identified, which was slightly higher than the median score for ICD recipients in the general population revealing a high level of device specific fears and anxiety. A higher level of shock-related anxiety was associated with poorer sexual function score in both men and women.


“ICDs are increasingly being implanted in this young and vulnerable patient population, yet the psychosocial issues are often overlooked. Our study is an example of dynamic research intended to help us better understand this growing population,” said Cook. “Improving outcomes and the quality of life in these young adults is critical and our results clearly show the importance of addressing their psychological well-being.”


Early identification of shock-related anxiety may pave the way for targeted interventions such as educational initiatives, treatment planning and psychological referral. Despite the overall access of ICDs in preventing premature mortality in at-risk patients, the psychological cost of living with an ICD can be significant. Proposed strategies to improve psychological well-being should include an effective communication strategy between patients and health-care professionals in regarding education and sexual concerns.
