Key result
Type D personality and anxiety sensitivity predict interviewer-rated anxiety while ICD shocks link to self-reported anxiety.
Why the study?
The role of personality in anxiety following implantable cardioverter defibrillator implantation was not well understood.
Do Type D personality, anxiety sensitivity, and ICD shocks predict anxiety in patients following ICD implantation?
Observational (n=308)
Do Type D personality, anxiety sensitivity, and ICD shocks predict anxiety in patients following ICD implantation?
Effect estimate: beta=0.18 (Type D personality); beta=0.19 (anxiety sensitivity)
p-value: p=0.021 and 0.016 respectively
Type D personality and anxiety sensitivity independently predict anxiety outcomes in ICD patients, highlighting the need to identify and support these vulnerable individuals.
Psychological traits may flag higher post-ICD anxiety risk; leaves open whether targeted interventions improve outcomes.
BACKGROUND: Studies have examined the relationship between shocks and anxiety, but little is known about the role of personality. Our aim was to examine the determinants of self-reported and interviewer-rated anxiety following implantable cardioverter defibrillator (ICD) implantation. METHODS: At baseline, that is, 0-3 weeks following ICD implantation, 308 ICD patients (82% men, mean age = 62.6 years) completed the DS14 (Type D personality) and ASI (anxiety sensitivity). The STAI (self-reported symptoms of state-anxiety) was assessed at baseline and follow-up, which was 2 months following ICD implantation. At this follow-up, the HAM-A interview (interviewer-rated anxiety) was assessed in a subsample (57%); the occurrence of ICD shocks was deduced from medical records. RESULTS: Analysis of covariance (ANCOVA) for repeated measures showed a significant interaction effect between time and shocks (F = 9.27, P = 0.003) with patients who had experienced a shock experiencing higher levels of self-reported anxiety at follow-up. The main effects of Type D personality (F = 33.42, P < 0.0001) and anxiety sensitivity (F = 66.31, P < 0.0001) were significant, indicating that these patients scored higher on self-reported anxiety across time points. Multivariable linear regression analyses yielded Type D personality (beta= 0.18, P = 0.021) and anxiety sensitivity (beta= 0.19, P = 0.016), but not shocks, as independent predictors of interviewer-rated anxiety. Covariates included gender, marital status, education, age, ICD indication, cardiac history, and comorbidity. CONCLUSIONS: Type D personality and anxiety sensitivity were independent predictors of both self-reported and interviewer-rated anxiety outcomes while ICD shocks were related to an increase in levels of self-reported anxiety only. Identification and support of ICD patients with Type D personality, increased anxiety sensitivity, or shocks is important.

Broek et al. (2008) conducted an observational in Implantable cardioverter defibrillator (ICD) implantation (n=308). Type D personality, anxiety sensitivity, and ICD shocks vs. Absence of these traits or events was evaluated on Interviewer-rated anxiety (HAM-A) and self-reported anxiety (STAI) (beta=0.18 (Type D personality); beta=0.19 (anxiety sensitivity), p=0.021 and 0.016 respectively). Type D personality and anxiety sensitivity independently predicted interviewer-rated anxiety, whereas ICD shocks were associated only with increased self-reported anxiety.
