Quality of Life in Young Adult Patients with a Cardiogenetic Condition Receiving an ICD for Primary Prevention of Sudden Cardiac Death

Prophylactic implantable cardioverter defibrillator (ICD) therapy prevents sudden cardiac death (SCD) among young adults with cardiogenetic conditions, but might reduce quality of life (QoL) due to potential device complications, ongoing medical appointments, and lifestyle restrictions. We investigated QoL in the first year after ICD implantation for the primary prevention of SCD and compared QoL scores with population norms. Consecutive patients with cardiogenetic conditions (aged 18-50 years) referred to the Academic Medical Center in Amsterdam to receive ICD therapy for the primary prevention of SCD between 2007 and 2009 were eligible. Patients completed questions about QoL (Short-Form 36 Health Survey; SF-36), depressive symptoms (Center for Epidemiologic Studies Depression scale; CES-D), anxiety (State-Trait Anxiety Inventory; STAI), and the impact of receiving ICD therapy on lifestyle and work, shortly before ICD implantation and after 2 months, 6 months, and 12 months. Thirty-five of 47 eligible patients participated. QoL was significantly reduced shortly before and 2 months after ICD implantation but improved over time and was comparable with population norms at 6 months and 12 months after ICD implantation. Yet, only about half of the patients believed they had a normal life like everyone else, and 28% had lost or changed their job due to their cardiogenetic condition and ICD therapy. Receiving a diagnosis of a cardiogenetic condition and subsequent ICD implantation was accompanied with a temporarily reduced QoL and a significant negative impact on professional life. Clinicians should inform their patients of the possible QoL consequences when deciding about ICD implantation in primary prevention of SCD in cardiogenetic conditions
