The association between type D personality, and depression and anxiety ten years after PCI.

OBJECTIVE: There are indications that type D personality and depression are associated in patients treated with percutaneous coronary intervention (PCI). However, at present it is unclear whether this relationship holds in the long term. This study's aim was to investigate the association between type D personality at 6 months post-PCI (baseline), and depression at 10-year follow-up. A secondary aim was to test the association between type D personality at baseline and anxiety at 10-year follow-up. METHODS: A cohort of surviving consecutive patients (N = 534) who underwent PCI between October 2001 and October 2002. Patients completed the type D personality scale (DS14) measuring type D personality at baseline, and the Hospital Anxiety and Depression Scale (HADS) measuring anxiety and depression at baseline and at 10 years post-PCI. RESULTS: At baseline, the prevalence of type D personality was 25 % (135/534). Type D personality patients were more often depressed (42 %) than non-type D personality patients (9 %). Response rate of anxiety and depression questionnaires at 10 years was 75 %. At 10-year follow-up, 31 % of type D personality patients were depressed versus 13 % of non-type D personality patients. After adjustments, baseline type D personality remained independently associated with depression at 10 years (OR = 3.69; 95 % CI [1.89-7.19]). Type D showed a similar association with anxiety at 10 years, albeit somewhat lower (OR = 2.72; 95 % CI [1.31-5.63]). CONCLUSIONS: PCI patients with type D personality had a 3.69-fold increased risk for depression and a 2.72-fold increased risk for anxiety at 10 years of follow-up.

Prognostic value of type D personality for 10-year mortality and subjective health status in patients treated with percutaneous coronary intervention.

OBJECTIVE: Given the debate around limitations and controversies in type D personality studies, we aimed to evaluate the prognostic value of 'synergistically' analyzed type D personality (interaction z-scores negative affectivity NA, and social inhibition SI) on 10-year mortality and on 10-year subjective health status in percutaneous coronary intervention (PCI) patients. METHODS: This prospective study comprised a cohort of 1190 consecutive patients who underwent PCI between October 2001 and September 2002 (73% male, mean age: 62years, range [27-90]years). At baseline, type D personality (DS14), and depression/anxiety (HADS) were assessed. Primary endpoint was 10year all-cause mortality; secondary endpoint was 10-year subjective health status (SF-36). RESULTS: After a median follow-up of 10.3years (IQR 9.8-10.8), 293 deaths of any cause (24.6%) were recorded. After adjustment for significant baseline characteristics, personality categories approached and dichotomously approached type D personality were associated with 10-year mortality, p<.05. Synergistically approached type D personality was not associated with all-cause mortality or subjective health status at 10years. In survivors, higher NA was associated with lower subjective health status. Type D was not associated with mortality after adjusting for continuous depression and anxiety in all approaches. CONCLUSIONS: Synergistically analyzed type D was not associated with 10-year all-cause mortality in PCI patients whereas dichotomous type D was. However, after adjustment for depression most of the findings had disappeared. Depression played an important role in this. Type D was not associated with 10-year subjective health status.
