It's official, stress is bad for you!
The effect of constant stress on a deep-lying region of the brain explains the increased risk of heart attack, a study in The Lancet suggests. In a study of 300 people, those with higher activity in the amygdala were more likely to develop cardiovascular disease - and sooner than others. Stress could be as important a risk factor as smoking and high blood pressure, the US researchers said. Heart experts said at-risk patients should be helped to manage stress.
