• Psychological distress (symptoms of anxiety and depression)
  
• Quality of life
  

• ICD therapies
  

About 30% of patients survive a cardiac arrest, and the majority of these receive an implantable cardioverter defibrillator (ICD) for prevention of sudden cardiac death (SCD). While ICD therapy offers survival benefit over drug therapy, there remain significant quality of life (QL) issues. About 50% of patients experience chronic anxiety about receiving an ICD shock. Anxiety and depression in turn appear to predispose to more arrhythmias necessitating ICD therapy. The aims of the current study are:

1. to evaluate a 8-session psychosocial intervention to help patients cope effectively with receiving an ICD for secondary prevention of SCD,
2. to determine if baseline measures of depression and anxiety predict ICD therapies (i.e., anti-tachycardia pace terminations and shocks); and
3. to explore if the psychosocial intervention results in less need for appropriate ICD therapies.

This study will randomize 218 ICD patients to receive either usual cardiac care (n=109) OR usual cardiac care plus CBT (n=109). Participants are recruited from two hospitals in Toronto that perform ICD implants (St. Michael's Hospital and the Toronto General Hospital). Counselling follows a CBT manual and involves both face-to-face sessions and telephone sessions. The telephone is employed as a means to deliver therapy as at least half of our ICD subjects reside outside of Toronto and all patients are prohibited from driving an automobile for the first six months following ICD implant. Outcome is assessed 6 and 12-months following the date of randomization and include measures of psychological function and quality of life. Secondary outcome is frequency of ICD therapies over follow-up (i.e., anti-tachycardia pacing terminations and DC shocks).
