Knowing more about Heart Attacks

Heart attacks, one of the greatest illness of heart, poses a serious health risk and can be life-threatening. They occur when a blockage in the coronary arteries disrupts blood flow to the heart, which causes permanent damage.

Best Heart Doctor in Jaipur mentions three types of coronary artery disease which can lead to a heart attack: -

  • ST segment elevation myocardial infarction (STEMI)
  • Non-ST segment elevation myocardial infarction (NSTEMI)
  • Coronary artery spasm

What is a heart attack?

A heart attack occurs when there is blockage in the coronary arteries. Coronary arteries carry blood to the heart, allowing it to function. A heart attack, also known as a myocardial infarction, occurs when a blockage develops in the coronary arteries and restricts the flow of blood to the heart.

Why do blockages occur?

Blockages occur when fat, cholesterol, and other substances build up, forming deposits called plaques in blood vessels. These plaques can become damaged over a period of time and might release platelets. Those platelets can cause blood to clot and block the flow. By obstructing this blood flow, these blockages can damage the heart muscles. The intensity of damage will depend on the size and manner of the blockage.


A heart attack results from one of the following types of coronary artery disease:


These attacks occur when the coronary artery is fully blocked, preventing blood from reaching the heart. This causes progressive damage to the heart muscle, which can stop its functioning.


NSTEMI heart attacks occur when the coronary artery is partially blocked and blood flow is severely restricted.

Coronary artery spasm

These spasms are also called silent heart attacks. They occur when the arteries connected to the heart contract, preventing blood flow to the heart.
