Personality and Long-term Mortality
CITATION:  Denollet, Johan, Sys, Stanislas U, Stroobant, Nathalie, Rombouts, Hans, et al. (1996, February 17). Personality as independent predictor of long-term mortality in patients with coronary heart disease. The Lancet, 347(8999), 417.

ABSTRACT:  Emotional distress has been related to mortality in patients with coronary heart disease (CHD), but little is known about the role of personality in long-term prognosis. We postulated that type-D personality (the tendency to suppress emotional distress) was a predictor of long-term mortality in CHD, independently of established biomedical risk factors.

Methods We studied 268 men and 35 women with angiographically documented CHD, aged 31-79 years, who were taking part in an outpatient rehabilitation programme. All patients completed personality questionnaires at entry to the programme. We contacted them 6-10 years later (mean 7.9) to find out survival status. The main endpoint was death from all causes.

Findings At follow-up, 38 patients had died; there were 24 cardiac deaths. The rate of death was higher for type-D patients than for those without type-D (23 [27%]/85 vs 15 [7%]/218; p<O 0.00001). The association between type-D personality and mortality was still evident more than 5 years after the coronary event and was found in both men and women.
