Changes in quality of life, depression, general anxiety, and heart‐focused anxiety after defibrillator implantation

AIMS: The Anxiety‐CHF (Anxiety in patients with Chronic Heart Failure) study investigated heart‐focused anxiety (HFA, with the dimensions fear, attention, and avoidance of physical activity), general anxiety, depression, and quality of life (QoL) in patients with heart failure. Psychological measures were assessed before and up to 2 years after the implantation of an implantable cardioverter defibrillator (ICD) with or without cardiac resynchronization therapy defibrillator (CRT‐D). METHODS AND RESULTS: One hundred thirty‐two patients were enrolled in this monocentric prospective study (44/88 CRT‐D/ICD, mean age 61 ± 14 years, mean left ventricular ejection fraction 31 ± 9%, and 29% women). Psychological assessment was performed before device implantation as well as after 5, 12, and 24 months. After device implantation, mean total HFA, HFA‐fear, HFA‐attention, general anxiety, and QoL improved significantly. Depression and HFA‐related avoidance of physical activity did not change. CRT‐D patients compared with ICD recipients and women compared with men reported worse QoL at baseline. Younger patients (<median of 63 years) had higher levels of general anxiety and lower levels of HFA‐avoidance at baseline than older patients. After 24 months, groups no longer differed from each other on these scores. Patients with a history of shock or anti‐tachycardia pacing (shock/ATP; N = 19) reported no improvements in psychological measures and had significantly higher total HFA and HFA‐avoidance levels after 2 years than participants without shock/ATP. CONCLUSIONS: Anxiety and QoL improved after device implantation, and depression and HFA‐avoidance remained unchanged. HFA may be more pronounced after shock/ATP. Psychological counselling in these patients to reduce HFA and increase physical activity should be considered.
