Having an unexciting occupation may increase your risk of a heart attack, believe researchers. Dull, steady work is associated with a faster and less variable heart rate, which, in turn, is linked to heart disease, say UK scientists. The team from University College London studied more than 2,000 male civil servants. The British Heart Foundation said the Circulation study findings could be linked to underlying depression. It is already known that people in low-paying jobs and with lower educational achievements have a higher risk of heart disease. Depression has also been linked with heart disease. Many of the men with low-grade jobs that Dr Harry Hemingway and colleagues studied also reported being depressed.
