荷兰的研究人员日前发现,环境污染能使流入心脏的血液减少,因而会加重心脏病。科学家在对赫尔辛基一个地区的45名心脏病患者的研究证实,志愿者们呼吸了两天被污染的空气后,流入心脏的血液量明显减少。要命的是,这种情况的发生,一般不会使人有疼痛感,人们在不知不觉间,就会由此而心肌梗塞和心血管故障,或者心跳加快,有时是两种情况同时发生。在受污染的空气中,心跳的平均速度从每分钟60次增加到9Q次。科学家们据此提出,心脏病人在受到污染的环境中活动,流入心脏的血液,比在纯净的空气中,要减少1/3。
Recently, researchers in the Netherlands discovered that environmental pollution can reduce the blood flow into the heart and thus increase heart disease. In a study of 45 heart patients in a district of Helsinki, scientists confirmed that volunteers who breathed two days of contaminated air significantly reduced blood flow to the heart. What is terrible is that this happens, the general does not make people have pain, people unconsciously, it will be due to myocardial infarction and cardiovascular failure, or rapid heartbeat, and sometimes the two cases occur at the same time. In contaminated air, the average heart rate increased from 60 beats per minute to 9Q. According to the scientists, heart patients in the contaminated environment, the flow of blood into the heart than in pure air, to reduce by 1/3.
