People who work three hours or more of overtime¹ per day run a 60-percent higher risk of bad heart problems compared to those who work regular hours, a study published in the European Heart Journal said.

一项研究发现，每天加班3个小时以上的人罹患心脏病的几率比正常下班的人高出60%。研究结果刊登在《欧洲心脏病学》杂志上。

The findings came from a long-term research project into 6,014 British civil servants aged 39-61, two-thirds of whom were men, who had healthy hearts at the start of the probe in the early 1990s.

这一发现来自一个长期研究项目，研究人员对英国6014名公务员进行了调查，他们的年龄介于39岁至61岁之间，其中三分之二为男性。他们在上世纪90年代初调查研究开始时都拥有健康的心脏。

At an 11-year monitoring point, 369 of the volunteers had either died of coronary heart disease (CHD) or had had a non-fatal heart attack or angina.

在监测11年后，其中369名志愿者不是死于冠心病，就是曾出现非致命的心脏病发作或心绞痛。

After accounting² for risk factors such as smoking, overweight and high cholesterol³, doctors found that working between three and four hours of overtime each day was associated with a 60 percent greater risk compared to those who did no overtime.

除了吸烟、体重过重和胆固醇高等危险因素外，医生们发现，每天加班三四个小时的人罹患心脏病的几率比不加班的人高出60%。
