Key result
Type D personality did not significantly predict 18-month mortality in patients with heart failure (HR 0.893).

Does Type D personality predict mortality in patients with heart failure?

Implication
Type D personality should not guide heart failure risk stratification; challenges prior reports but leaves prognostic value open for confirmation.

Population
706 adults with symptomatic heart failure (NYHA II-IV) and evidence of structural underlying heart disease, followed for 18 months.

All-cause mortality at 18 monthshard clinical
Main Result
Hazard Ratio: 0.893 (95% CI 0.582–1.37)
Type D personality does not have prognostic value for mortality in heart failure patients, challenging previous smaller studies that suggested it as an independent risk factor.
Limitations
- Secondary analysis of a clinical trial not designed expressly to test the prognostic value of Type D personality
- Follow-up period was limited to 18 months, so effects on mortality apparent only later cannot be excluded
- The prevalence of Type D personality (13%) was lower than in previous studies, possibly because recruitment to a disease management program attracts a lower proportion of patients with Type D personality.

Coyne et al. (2011) conducted an observational in Heart failure (n=706). Type D personality vs. Non-Type D personality was evaluated on All-cause mortality (HR 0.893, 95% CI 0.582-1.370). Type D personality did not significantly predict 18-month mortality in patients with heart failure (HR 0.893).
