PARIS, Dec 14 (AFP) - The pressure of meeting an important deadline at work increases by a factor of six the risk of suffering a heart attack within 24 hours, Swedish doctors say.
A short burst of intense pressure appears to have greater strain on the heart than accumulated stress over 12 months, according to their study, carried out among 3,500 people aged between 45 and 70.
The research appears on Tuesday in the Journal of Epidemiology and Health, published by the British Medical Association (BMA).
The Karolinska Institute study also suggests that praise from the boss could also be a risk factor for employees with weak hearts.
In some cases, workers who were beavering away on an important job and were praised by their superior were felled by a heart attack within a day.
That risk is hard to quantify, though, because it is unclear whether the stress could be attributable to the deadline, the boss or both.
The data come from people in the Stockholm area who filled in questionnaires and responded to interviews and health examinations between 1992 and 1994.
