Mental stress can literally be heart-breaking for women – leading them to be more likely than men to suffer coronary problems, a study claims.
The findings could help explain why women are more likely than men to be hit by coronary symptoms after emotional upsets such as losing a spouse.
The U.S. study examined the effects of mental stress on blood flow through the heart.
