Swedish research suggests that men who don’t express their workplace anger openly if they are unfairly treated at work double their risk of a heart attack.

The researchers looked at 2,755 male employees in Stockholm who did not have a heart attack when the study began.

They were questioned about how they coped with conflict at work, either with superiors or colleagues.

The researchers say their study shows a strong relationship between lingering anger and heart disease.

The men were questioned about the means that they adopted to deal with the things face-to-face and whether they allowed matters to pass without acting upon them or saying anything about them.

They were asked if they suffered from headaches and stomach aches and a bad temper at home.

As per the hospital records they were checked for smoking, drinking, physical activity, education, diabetes, job demands and their freedom to take decisions.

It was found that men who allowed matters to pass without saying anything about them had a higher risk of heart ache or heart disease.
