You may be at greater risk for heart disease if you tend to be competitive and argumentative.
In a recent study published in Psychosomatic Medicine, 300 older couples were asked to rate their spouses on an antagonism (a component of hostility) scale—an indicator of people who were inclined to be suspicious of others, competitive, or argumentative. Subjects underwent computed tomography scans to measure their arteries for calcium—a marker of plaque build-up that increases risk for heart attack and stroke.
Those with higher antagonism scores correlated with significant calcium build-up and were more likely to have arteries clogged with plaque.
