CHICAGO – Patients who described themselves as highly optimistic had lower risks of all-cause death, and lower rates of cardiovascular death than those with high levels of pessimism, according to an article in the November issue of The Archives of General Psychiatry, one of the JAMA/Archives journals.

According to the article, major depression is a known risk factor for cardiovascular death. However, the relationship between optimism and death has not received as much attention.

"'In conclusion, we found that the trait of optimism was an important long-term determinant of all-cause and cardiovascular mortality in elderly subjects independent of sociodemographic characteristics and cardiovascular risk factors,' the authors write. 'A predisposition toward optimism seemed to provide a survival benefit in elderly subjects with relatively short life expectancies otherwise.'

'Our results, combined with the finding that hopelessness was associated with an increased incidence or progression of disease, suggest that dispositional optimism affects the progression of cardiovascular disease,' the researchers state. 'Although optimism reduces the risk of cardiovascular death through mechanisms largely unaffected by baseline values of physical activity, obesity, smoking, hypertension, and lipid profile, pessimistic subjects may be more prone to changes across time in risk factors that affect the progression of cardiovascular disease (e.g., the development of smoking habits, obesity, or hypertension) than optimistic subjects. Dispositional optimism may also be associated with better coping strategies that are adhered to throughout life.'
