What
is
an
implantable
cardioverter
CoRPS
defibrillator (ICD)?
• The ICD can shock with up to 700800 volts
• “It’s like getting kicked in the chest
by a big horse!”

ICD therapy: Benefits and side effects
Epstein, J Am Coll Cardiol 2008
CoRPS
ICD therapy: Benefits and side effects
• Complications (lead fractures, dislodgement, and infection)
• Shocks that are inappropriate  mortality risk ?
• Potential malfunctioning, as notified with a device recall
• Significant anxiety and depression in 20-30% of patients
• Patient´s psychological reaction to the device may increase
the risk of arrhythmias
Risk that patients will refuse this potentially
life-saving treatment

Distress and arrhythmias
Mood states also predict arrhythmic events:
–
Mood disturbance (OR: 1.14-1.16) 3 mths and 6
mths arrhythmia
–
15 min prior to shocks, independent effects of
anger, (OR: 1.83), and mild-to-moderate
physical activity (OR: 1.46); no effect for anxiety,
worry, sadness, happiness, challenge, interest,
and in control
Dunbar et al. Depress Anxiety 1999; Lampert et al. Circulation 2002
CoRPS
Distress and arrhythmias
–
Depression: HR: 3.2 - time to first shock for VT/VF;
HR: 3.2 – all shocks for VT/VF including recurrent
episodes (adjusted analysis)
–
Anxious Type D’s: HR: 1.72 (95% CI: 1.03 to 2.89) 1
year ventricular arrhythmias, independent of sex,
age, ischemic etiology, left ventricular dysfunction,
prolonged QRS duration, and medication); no effect
for anxiety and depressive symptoms

OBJECTIVES
Primary:
• To investigate whether the web-based intervention is
superior to usual care in terms of reducing anxiety,
depression, and ICD concerns as well as improving ICD
acceptance and QoL
• To investigate the cost-effectiveness of the web-based
intervention and whether the web-based intervention is
associated with reduced health-care utilization
CoRPS
Secondary:
• To examine whether psychological (i.e., Type D personality
and positive affect) and clinical factors (i.e., cardiac
resynchronization therapy (CRT)) moderate the effect of
the intervention, with a view to developing risk profiles of
patients who are less likely to benefit from the intervention
Explorative:
• To explore whether the web-based intervention influences
physiological parameters (i.e., ventricular arrhythmias and
the cortisol awakening response (CAR))

Patient population
Consecutive ICD patients recruited from 3 centers:
₋ Amphia Hospital, Breda
₋ Catharina Hospital, Eindhoven
₋ Erasmus Medical Center, Rotterdam
CoRPS
Power analysis based on the assumptions :
– expected between group effect size of .30
– alpha = 0.05
– power = 0.80 (two-sided test)
– 350 patients are needed (i.e., 175 in each
condition). Given an expected response rate of
50% (earlier study = 82%) 700 patients need to
be approached

Physiological measures
• Salivary cortisol, using the Salivette, assessed at 3
out of the 4 time points (i.e., T0 = 5 to 10 days after
ICD implantation; T1 = 14 weeks post-implantation;
T3 = 52 weeks post-implantation)
• Four samples will be taken at each time point and
on the consecutive day, that is (a) when waking up,
(b) ½ hour later, (c) 11.00 a.m., and (d) 3.00 p.m.
CoRPS
Other measures
• Clinical: ICD indication, etiology, LVEF, CRT, comorbidity, type of ICD therapy (ATP vs. shock;
appropriate vs. inappropriate), QRS-complex,
cardiac medication, etc.
• Demographic: Sex, age, marital status, education,
working status
• Other: Smoking status, participation in cardiac
rehabilitation since ICD implantation, the use of
psychotropic medication, help-seeking from a
psychologist/psychiatrist
CoRPS
Study endpoints
Primary:
• Anxiety; depression; ICD concerns; ICD acceptance;
quality of life; health care utilization; costeffectiveness of the intervention
Secondary:
• Ventricular arrhythmias; cortisol awakening respons
Long-term:
• Mortality

Advantages of web-based approach
• Low-threshold accessibility
• Less stigma – no face-to-face meetings with
therapists
• Obtain treatment at any time and place, work at
own pace and review the material as often as
desired
• No extra hospital visits – being reminded less of
illness as the context of the intervention is
different
CoRPS
Clinical and societal relevance
• Immediate applicability in health care
• Identification of high-risk patients  screening
• Personalized care  optimization of clinical
management of device patients
• Reduced health-care utilization
• Increased cost-effectiveness
