Researchers say people traveling in traffic are three times more likely to suffer a heart attack. They say the risk of a heart attack is greatest within an hour of being in traffic.
The findings are based on a German study of almost seven hundred people who suffered heart attacks. The patients described their activities during the four days before their heart attack. Researchers found that those who had been in traffic were three times more likely to have a heart attack within one hour, compared to those who had not been in traffic. Most of those in the study had been traveling by car. But some had been on bicycles and others were on buses.
Research shows that people in cars and buses are exposed to ten times the amount of pollutants as people walking on the street. That is largely because they breathe in the particles and gases released from the vehicles in front of them. Over time, these small particles speed the buildup of a sticky substance in the blood. This can cause blockages to form in the arteries around the heart and lead to a heart attack.
Other studies have also linked heart trouble to stress, similar to the kind that people face while driving in heavy traffic. But the researchers of the latest study say they do not know whether the increased heart attack risk is the result of stress or pollution. They suggest it may be a combination of stress, noise and pollution. Experts say the research shows the need for cleaner vehicles and better city planning to lower the risk of the heart attack.
According to the study, which of the following is the safest for people who are suffering heart attacks?
选项
A、Going on foot.
B、Driving a car.
C、Taking a bus.
D、Riding a bicycle.
答案
A
解析
文章第二段第三句提到研究的结果,与不乘坐交通工具的人相比,乘坐交通工具的人突发心脏病的几率高出三倍。第四、五句进一步分析他们乘坐的交通工具,其中大部分人乘坐汽车,还有一些骑自行车,其余的乘坐公交车。乘坐汽车、公交车和骑自行车心脏病的发病率都比较高,因此可以推断步行应该是最安全的出行方式。所以确定A)为本题的答案。
