Heart Attack, Stroke-Prone Arteries More Common in Nasty People

An Antagonistic Personality Might Increase Your Risk For Cardiovascular Disease

(ABC News) — People with antagonistic or disagreeable personalities have thicker arterial walls that may make them more prone to heart attacks and strokes, researchers said.

The carotid artery lining was significantly thicker in people who rated low on a scale of agreeableness, reported Angelina Sutin of the National Institute on Aging in Bethesda, Md., and colleagues.

In a study of 5,614 residents of the Italian island of Sardinia, those ranking in the lowest 10 percent of agreeableness were 1.4 times as likely to have thickening in their lining of their carotid artery, the researchers found. This held true even after the researchers adjusted for cholesterol levels, smoking status and other risk factors.

The researchers also found that an antagonistic personality predicted increased thickening over approximately three years of follow-up.
