Key result
Type D personality is linked to ~91% higher all-cause mortality in younger ICD patients.
Why the study?
Does Type D personality increase the risk of all-cause and cardiac mortality in younger versus older patients with implantable cardioverter defibrillators?
Cohort (n=589)
Does Type D personality increase the risk of all-cause and cardiac mortality in younger versus older patients with implantable cardioverter defibrillators?
Hazard Ratio: 1.91 (95% CI 1.09–3.34)
Type D personality is an independent predictor of all-cause and cardiac mortality in younger (≤70 years) but not older ICD patients, highlighting the need to consider age-related differences in psychosocial risk.

Supports age-stratified psychosocial assessment in ICD patients; leaves open whether Type D-targeted interventions improve outcomes.
Denollet et al. (2013) conducted a cohort in Cardiac arrhythmias (n=589). Type D (distressed) personality vs. Non-Type D personality was evaluated on All-cause mortality (HR 1.91, 95% CI 1.09-3.34). Type D personality was independently associated with increased all-cause mortality (HR 1.91; 95% CI 1.09-3.34) and cardiac mortality in younger ICD patients, but not in older patients.
