Poor air quality leads to stroke besides respiratory problems says study

Indian capital has the worst air quality in the world. Pollution level is so high in New Delhi, that Beijing looks a very clean city. There is no surprise, that the mega city has got the ignominious tag of being the most polluted city in the world.

There is no surprise that the high pollution actually perpetuates respiratory problems, it also ups risk of suffering a stroke, a new study has claimed.

While talking about the findings of the study Barbara Hoffmann from the Heinrich-Heine-University Dusseldorf in Germany said, “Long-term exposure to fine-particle dust is associated with a higher risk of stroke, regardless of the subject’s exposure to noise at his or her home address”. In a population of the German Ruhr region, Hoffmann investigated how often stroke and cardiovascular disease occurred, as well as how much particulate matter and noise inhabitants were exposed to.

Information regarding stroke or cardiovascular disease occurrence and/or associated mortality was collected annually. In addition, the authors evaluated exposure to particulate matter and noise according to participants’ place of residence.

In a report researchers said, “The results indicate that stroke is more likely to occur with increased air pollution. The results for coronary events are less clear, and exposure to noise pollution showed no clear effect”. The authors point out, however, that the data indicates a tendency for increased risk of cardiovascular disease through particulate matter exposure. The study was published in the journal Deutsches Arzteblatt International.
