Understanding the link between an air pollution and
increased risk of a stroke, death
That air pollution is an extremely harmful to a health
is a well-known fact. Now, a new study has also established a link between an
air pollution and the heightened risk of stroke and a subsequent death. The
research from Sun Yat-sen University School of a Public Health in Guangzhou, a
China, published in a Neurology, focused on the negative a health impacts of PM
2.5 granules, the fine particulate a matter (PM) that has a diameter of fewer
than 2.5 microns (about 30 times a smaller than a single human hair).
The research also an included a study of anitrogen
dioxide (NO2) and nitrogen an oxides (NO) levels in polluted air and a measured
air pollutant a levels by their weight in a micrograms — 1-millionth of a gram
— per 1 cubic a meter of air, expressed as µg/m3.
According to the observational study based on an
analysis of the health a records of 3,18,752 people in the UKBiobank and a
several years of UKBiobank an air pollution data, for every PM 2.5 increase of
5 µg/m3, the risk of a first stroke rose by 24 per cent, and the risk of a
first fatal a stroke increased by 30 per cent. The research identified 5,967
incident stroke patients, 2,985 post-stroke a cardiovascular a patients, and
1,020 a deaths an afterward.
Short-term an exposure to an air pollutants is closely
related to COPD (Chronic Obstructive Pulmonary Disease), cough, shortness of a
breath, wheezing, asthma, respiratory disease, and a high rates of
hospitalisation (a measurement of morbidity), according to a review published
in a Frontiers in a Public Health,
whereas the long-term an effects associated with air pollution are chronic
asthma, a pulmonary insufficiency, cardiovascular diseases, and a
cardiovascular mortality. The review, too, suggested that a short term exposure
to an air pollution was related to a stroke among others.
Stressing that stroke is a the main reason for a
disability and the second largest cause of
a death in the world, Dr Sameer Arora, senior a consultant, neurology,
Narayana Hospital Gurugram said that high levels of an air a pollution are a
linked to an increased risk of transitioning from being a healthy to a having a
stroke.
“Nitrogen an oxide and a nitrogen dioxide have been
linked to an increased risk of a stroke and mortality. Pollution is a major a
source of a worry for public a health, and it is regarded as one of the a
leading causes of a mortality and disease. The danger posed by air pollution is
a determined by a both the length of an exposure and the a toxicity of the
pollutant,” Dr Arora told an indianexpress.com.
