Mild air pollution can also affect the heart

may also affect the heart for long periods of time in mild air pollution, leading to heart changes similar to those in the early stages of heart failure, according to a new british study.
, including Queen Mary, University of London, analysed data from a long-term british survey involving about 4,000 British volunteers. The subjects answered questions about lifestyle and underwent heart and blood tests.
, published in the new issue of the American journal
, found that those who lived near roads and were exposed to nitrogen dioxide or PM2.5 (fine particulate matter) pollution for a long time were more likely to develop left and right cul-de-serum hypertrophomation. Moreover, the more serious the air pollution, the more obvious the problem of hypertrophobies. Similar heart changes can be observed in the early stages of heart failure.
it is worth noting that the annual average of air pollution in the environment of these volunteers is within the recommended level in the UK, which is less than 25 micrograms per cubic metre.
researchers say this is an observational study and does not lead to cause-and-effect conclusions, but it has been observed that heart structure changes significantly in even mild air pollution environments, which means that mild air pollution can also affect health. The findings are another reminder that people should pay attention to air pollution control and self-protection. (Source: Zhang Jiawei, XinhuaNet)
