Hostility bad for your heart. (Fotolia)


 

Hostile people may have a greater chance of developing heart disease, a new study says.

University of Montreal researchers have drawn links between a hostile temperament and tumour necrosis factor (TNF). The chemical causes inflammation in the body, including in the circulatory system, and excess TNF production can cause heart problems. Bianca D'Antono's team studied 199 men and women, cross-referencing their temperaments with signs of inflammation.

"A link has been established between hostility and these markers in several study subjects with this type of temperament," D'Antono said.

She said the correlation was highest among younger test subjects, particularly women. D'Antono said the test subjects didn't have heart disease or illnesses that could have caused inflammation.

"Our study confirms that personality plays a role in heart disease and that hostility has effects on the body's inflammatory mechanisms."

The findings appeared in the Journal of Psychosomatic Research.
