Can heart attack be triggered by air pollution - By Dr. Ritwick Raj Bhuyan

Air quality in Delhi and its adjoining areas continued to worsen triggering a health crisis. This may lead to a spike in chronic cough cases, respiratory problems in children and adults as well as contributing to respiratory and cardiovascular diseases, and even premature death. Study found that long-term exposure to particulate matter and nitrogen oxides at levels close to the National Ambient Air Quality Standards (NAAQS) can prematurely age blood vessels and contribute to a more rapid buildup of calcium in the coronary artery.

This buildup of calcium can restrict blood flow to the heart and other major blood vessels —increasing the likelihood of cardiovascular events like heart attack and stroke. Healthy individuals exposed to air particle pollution over the long term had accelerated cases of atherosclerosis—to the extent that some participants’ risk for heart attack increased.

Here are a few steps you can take to reduce the harmful effects of air pollution and keep your heart safe: -

• Limit outdoor activities
• Avoid situations where you are exposed to a high level of air pollution.
• Try using less energy in your home 
• Install air purifiers at home
• Eat a healthy diet consisting of plenty of fresh fruits and vegetables
• Plant more trees 
• Make sure to talk to your doctor, especially if you have a heart or circulatory condition, about understanding the risks in your area, practical tips to reduce exposure to pollution.
