Dusty air triggers heart attack

Tehran, July 27, IRNA - Dusty air results in respiratory system disorders in cardiovascular patients which may raise the risk of heart attack.

Dr. Seyyed Hamid Reza Mortezavi, a fellow in asthma, allergy and immunology, said suspended particles in air are categorized on the basis of their diagonal. The smaller the particles, the more likely they are to enter the deeper parts of the respiratory system.

Bigger particles are more likely to stick to nostrils and prevented from penetrating into deeper parts of respiratory system, 'Iran Daily' quoted hims as saying recently.

The specialist said that disorder of the respiratory system disturbs blood supply to the heart and this increases the risk of heart attack.

Suspended particles in air usually carry some contaminants and allergens some of which are able to intensify symptoms of asthma and even may prepare the grounds for afflicting people with diseases, he added.

Mortezavi strongly recommended that high-risk people, including children, old people and cardiovascular patients, avoid going out when air pollution is at unhealthy levels, or wear proper mask, for example those equipped with standard filters.

Pointing to the risks of exercising in dusty air in the open environment, he said that exercising involves deep breathing and thus the possibility for suspended particles to enter deeper regions of the respiratory system becomes greater.
