According to a US study, it has been revealed that joblessness at the age of 50 or in early 60s can prove costly to heart. Joblessness can make one suffer from heart attack, said study of more than 13,000 people.

The study, which has been published in the Archives of Internal Medicine, has found that those, who have left the job on their own, do not face an increased risk of suffering from heart attack. Researcher Dr Linda George from Duke University in North Carolina said that difference could be due to the reason of stress.

People, who want to work but are not getting the same, are under great stress, which increase the chances to suffer from heart attack. However, no such fear is present when one has left the job with his own wish, so there is no point of taking stress.

"This is a sizeable effect and of a similar size to other well-known, established risk factors for heart attack including smoking and obesity", said George.

Dr. Donna Arnett from the American Heart Association said that the study is a perfect example to show that a number of stress factors are present in the life that can increase heart attack risk.
