Arguing with your partner really can break your heart. Research now shows it can contribute to hardening of the coronary arteries.

Such impact on the heart is more common in wives when they and their husbands express hostility during disagreements, and more common in husbands when either they or their wives act in a controlling manner. "Women who are hostile are more likely to have atherosclerosis (hardening of the coronary arteries), especially if their husbands are hostile too," said University of Utah professor Tim Smith, who presented the findings at the annual meeting of the American Psychosomatic Society.
