Heart Attack: Important Facts You Should Know

Heart attack has been one of the leading causes of death in India. As per the estimate, almost 24.2 % of all death in India are due to cardiovascular diseases. Heart attack or myocardial infarction is the major contributor to this. The occurrence of a heart attack when checked in a research from 2014 to 2019 has been seen to increase by over 50%. The sudden demise of television actor Siddharth Shukla and singer KK due to a heart attack has shaken the country. It’s time to understand the basics of heart attack and adapt to healthy lifestyle changes to prevent this dreadful event. 

What is a Heart Attack?

One of the most essential muscles in the body is the heart. This is because the heart pumps blood via the circulatory system, which transports the oxygen required for living throughout the body. To function correctly, the heart requires a constant flow of oxygen-rich blood. When the heart is deprived of oxygen because of the blockage in one of the blood vessels that provide blood to the heart, a heart attack occurs. Myocardial infarction is another name for a heart attack (MI). When a coronary artery is blocked during a heart attack, blood flow to the heart is cut off, limiting the quantity of oxygen delivered to the heart. The longer the blockage goes untreated, the more harm it does to the heart. The heart muscle is eventually damaged and if it isn't treated to restore blood flow, the heart can be permanently injured.

Heart Attack: What Causes It?

Coronary heart disease, also known as coronary artery disease, occurs when the blood arteries that feed blood to the heart become blocked. Atherosclerosis, a condition in which fat, cholesterol, and other chemicals pile up and form plaque in the arteries, can cause blockage. This plaque can get larger over time, narrowing the artery and causing it to harden. This lowers blood flow to the heart, depriving the heart of the oxygen it requires to operate correctly. The other heart attack causes include:

  • Small plaques in your arteries: They may not block your blood vessels, but can cause blood clots to form on these plaques which may obstruct blood flow
  • Spasm in coronary artery
  • Embolism: A coronary artery embolism occurs when a blood clot travels through your bloodstream and gets stuck in your coronary artery. This can block blood flow through your artery.
  • Spontaneous tear in your blood vessel: There is then a possibility of blood clots or a blockage of your artery if the torn tissue blocks your blood vessel.

The main risk factors that increase the chances of a heart attack are: 

  • Diabetes mellitus
