Long-term stress linked to increased risk of heart attack

London, Feb 11 : Taking stress may be not be good for your heart as a new study suggests that long-term stress may lead to increased risk of heart attack.
The study, published in the journal Scientific Reports, indicated that people with higher levels of cortisol are at an increased risk of heart attack.
“The levels of the stress hormone cortisol differed between people who have had a heart attack and those not affected. This suggests that cortisol in hair may be a new risk marker for heart attacks,” said Tomas Faresjo from the Linkoping University in Sweden.
Cortisol is a steroid hormone that regulates a wide range of processes throughout the body, including metabolism and the immune response. It also has a very important role in helping the body respond to stress.
To study the long-term stress due to a lack of reliable methods, the team improved the use of a new biomarker, in which they measure the levels of the stress hormone cortisol in hair.
This enables measurements of cortisol levels backwards in time, similar to the growth rings in a tree. This analysis method is at the moment only available in research settings.
