According to Nicole Vogelzangs, PhD, of VU University Medical Center in The Netherlands and lead author of a study on the subject, high levels of the stress hormone cortisol strongly predicts cardiovascular death among persons with and without pre-existing cardiovascular disease. “Previous studies have suggested that cortisol might increase the risk of cardiovascular mortality, but until now, no study had directly tested this hypothesis,” said Vogelzangs. “The results of our study clearly show that cortisol levels in a general older population predict cardiovascular death, but not other causes of mortality.”
Chronic stress induces chronic high levels of cortisol in the bloodstream, which in turn predicts cardiovascular death. Chronic stress kills.
“Cortisol is an important component of the stress system of the human body but in higher concentrations can be harmful,” said Vogelzangs. “Our study shows that older persons with high levels of cortisol have an increased risk of dying from cardiovascular disease. This finding significantly adds evidence to the belief that cortisol can be damaging to the cardiovascular system.”
High blood cortisol levels should indicate immediate work on creating an effective strategy for calming down in the face of stress.



In a study appearing in the May edition of Research on Social Work Practice, Geisinger Senior Investigator Joseph Boscarino, PhD, MPH and his co-researchers examined psychological stress, job burnout and secondary trauma among 236 New York City social workers following the Sept. 11 terror attacks.
