英国《独立报》引述剑桥大学公共风险理解学教授大卫·斯比格哈特的话说,如果大家都停止性活动,或许能减少心脏病发作,可是发出健康号召让大家为了心脏健康而杜绝性活动肯定没人听。

在以上所有的心脏病诱因中,空气污染造成的心脏病发作比率最高,达7%。这是因为几乎人人都是空气污染受害者。

心脏病专家认为,这一研究解释了为什么某人会在某时某刻突然心脏病发作,因为这些诱因就像是“驼背上的最后一根稻草”,让不堪重负的心脏突然之间停止工作。

Because so many people are exposed to dirty air, air pollution while stuck in traffic topped the list of potential heart attack triggers, with the researchers pegging 7.4 percent of heart attacks to roadway smog. ~7 A5 b3 N" G2 i" h0 `

Among everyday activities, exerting yourself physically was linked to 6.2 percent of heart attacks, indulging in a heavy meal was estimated to trigger 2.7 percent, and sex was linked to 2.2 percent.

The researchers stressed that the risk for heart attack from any one of these factors to a particular person at any given time is extremely small. But spread out over the population, they can add up.; h, Z K! A7 [1 A# z; h: c& j
' Q. _7 D3 I4 R. hFor example, air pollution is a minor trigger for heart attacks, but since so many people are exposed to smog, it triggers many more heart attacks than other more potent triggers, such as alcohol and cocaine.人在德国 社区$ T: U/ d" ~0 z" H3 \, e/ j; ~* v

"Small risks can be highly relevant if they are widely distributed in the population," explained lead researcher Tim S. Nawrot, assistant professor of epidemiology at the Hasselt Centre for Environmental Sciences at Hasselt University in Diepenbeek, Belgium.

Commenting on the study, Dr. Gregg Fonarow, spokesman for the American Heart Association and professor of cardiology at the University of California, Los Angeles, added that "based on these findings, improvement in air quality and reduction in traffic may not just help the environment and increase quality of life, but also substantially decrease the incidence of [heart attack]."人在德国 社区; H/ r2 P' f1 X
