Air PolutionWe would expect that getting caught in the traffic or listening to loud honks are common city annoyances that could cause stress and affect our heart and health.

But there’s another silent killer lurking in the city streets. Something so quiet and hidden that we may not notice it most of the time. But it increases your risk of developing heart attack by a whopping 13 percent.

Researchers have identified that smog can increase the chances of developing heart attack and angina (which refers to the chest pain associated with heart attack).

Smog is a form of air pollution. It is basically a mixture of fog and smoke, which contains tiny particles of dust that can enter the lungs through the nasal passages. For the study, the researchers analyzed data from more than 100,000 people in Europe. The people chosen for the study had no previous history of heart disease. They were followed-up for a period of 11.5 years. After accounting for other risk factors as well as unhealthy habits like smoking, the researchers hit upon what effects smog could have on heart health.

A 5 microgram per cubic meter increase in small particulate matter resulted in 13 percent increase in risk of coronary problems. Similarly, an increase in large particulate matter by 10 micrograms per cubic meter increases risk of coronary heart problems by 12 percent.

The current limits for particulate matter are 25 micrograms per cubic meter in Europe and 12 micrograms per cubic meter in USA. The WHO recommends 10 micrograms per cubic meter.

Air pollution results in 3.2 million deaths across the world in a year. The study sheds light on the possible association between long term exposure to particulate matter in air and coronary disease. A good way to deal with smog would be to wear a nose mask while commuting, or if you have the option, move out of a place with high levels of air pollution.
