CoRPS Prevalence of distress in ICD patients Psychological morbidity: Anxiety/depression ≈ 25% Posttraumatic stress ≈ 12% Chronic anxiety ≈ 50% Versteeg et al. Int J Cardiol 2011;146:438-9; Pedersen et al. Int J Cardiol 2011;147:420-3; von Känel et al. J Affect Disord 2011;131: Subset of patients (1 in 4) Depression: 11% to 28% Anxiety: 11% to 26%
CoRPS Should we take distress in ICD patients seriously? Braunschweig, Boriani,... Pedersen et al. Europace 2010;12: Stressed out - ME???!!!
CoRPS Down in the dumps Feeling blue Angry Worried Bad mood Unhappy Type D ? Type D personality - burden of increased negative emotions and inhibition No!! I do not want to share my emotions with others… No!! I do not want to share my emotions with others…
CoRPS Type D personality: An important risk marker for poor prognosis Denollet et al. Circ Cardiovasc Qual Outcomes 2010;3: Mean OR across 9 studies: 3.7 [95% CI ]

CoRPS What about depression?
CoRPS Study objectives To examine: (i)the influence of depression on mortality (ii)whether specific depressive symptoms drive the relationship between depression and mortality
CoRPS Methods: Participants Consecutive patients (N = 430; 79% men; mean age = 58 ± 12) with a first-time ICD or CRT-D Implanted between August 2003 to March 2010 in the Erasmus Medical Center, Rotterdam Participating in Mood and personality as precipitants of arrhythmia in patients with an Implantable cardioverter Defibrillator: A prospective Study (MIDAS)
CoRPS Methods: Design and measures Prospective follow-up study – 2 ½ years (range 47 days to 3 years) Demographic and clinical characteristics (incl. device therapy) obtained from medical chart abstraction and purpose-designed questions Patients completed: o 7-item depression scale at baseline – Hospital Anxiety and Depression Scale (HADS) Statistical analysis: Univariable and multivariable Cox’s proportional hazard regression analysis
CoRPS Results: Mortality stratified by depression (cut-off ≥8) 11% died (47/430) during the follow-up period HR: 2.31 [95% CI: ]; p = % 18.5% * HR: 2.16 [95% CI: ]; p = 0.01 * Adjusted for gender, age, indication for ICD implantation, symptomatic heart failure, beta-blocker therapy, appropriate shocks HR: 1.12 [95% CI: ]; p < Percentage
CoRPS Results: Mortality stratified by specific depressive symptoms HADS-D (item)HR[95% CI]p “Do not enjoy the things I used to” (#2)1.57[ ]0.004 “Cannot laugh and see funny side” (#4)1.44[ ]0.06 “Do not feel cheerful” (#6)1.33[ ]0.09 “Feel as if I am slowed down” (#8)1.33[ ]0.08 “Lost interest in my appearance” (#10)1.85[ ]< “Hardly ever look forward with enjoyment to things” (#12) 1.70[ ]< “Cannot enjoy a good book radio or TV program” (#14) 1.30[ ]0.07
CoRPS Take home message Depression was associated with a 2-fold risk for mortality – independent of demographic and clinical risk factors including shocks Cardio-toxic symptoms of depression – tapping into feelings of anhedonia (i.e., lack of positive affect) but also depression Depression in ICD patients should be taken seriously – hampers patient survival despite state- of-the-art treatment
