Staff Reporter,

Air pollution is everywhere. It’s intensity may variate when compare in urban and rural background but no one would deny its existence at every place. What makes the issue more concerning is it’s association with diseases especially respiratory and heart disorders which ultimately take the form of public health problem.


According to Dr KK Agrawal, President, HFCI, Air pollution, and specifically fine particulate matter, is associated with increased cardiovascular disease mortality. It has emerged as a potentially modifiable risk factor for the development of cardio-vascular diseases.


Dr Agrawal expressed that multiple observational studies have demonstrated an association between fine particulate air pollution (primarily from the use of fossil fuels in automobiles, power plants, and for heating purposes) and cardiovascular and cardiopulmonary mortality as well as an increased risk for the development of acute coronary syndrome.


There is increasing evidence for the role of environment in pathogenesis in many diseases. Children below 5 years of age and adults older than 50 years are most at risk. A global assessment of the burden of disease from environmental risks by the WHO has shown that 23% of global deaths and 26% of deaths among children under five are due to modifiable environmental factors. Exposure to particulate air pollution also may be associated with acute heart attack. This may be due, in part to a sympathetic stress response, as detected by changes in heart rate variability, the production of cytokines, and an increased vulnerability to plaque rupture. Some responsible pollutants include carbon monoxide, nitrogen dioxide, sulfur dioxide, and small particulate matter.


Short-term particulate exposure contributed to acute coronary events (heart attack) in patients with underlying coronary artery disease.
