Family stress may increase the chance of developing angina, according to a new study.
Research, published in the Journal of Epidemiology and Community Health, found that dealing with worries from children, partners and other family members was significant in the development of angina.
Risk was particularly high in those experiencing a high level of stress from their children and other family members although friends and neighbours are not particularly significant - unless they are argumentative.
The authors, from the University of Copenhagen, said: "Excessive demands and serious worries from significant others seem to be important risk factors for development of angina."
Angina is a feeling of pain or discomfort in your chest which can feel tight, dull or heavy and usually lasts only a few minutes.
Some people with the condition may also experience breathlessness, fatigue, nausea, dizziness and restlessness.
