Angina is chest pain or discomfort caused when the heart does not get enough blood.
Danish researchers tracked 4,500 men and women in their 40s and 50s. None of the participants had heart problems.
After the six years of follow-up, more than 9 percent of participants had symptoms of angina.Rela
Those who had troublesome relationships with a partner or a child had nearly 3 times the risk of chest pains.
Worries from other relatives nearly doubled the risk, while concerns or demands from friends and neighbors had little effect.
The study is published in the latest online edition of the Journal of Epidemiology and Community Health.
