A heart attack, or myocardial infarction (MI), is permanent damage to the heart muscle. “Myo” means muscle, “cardial” refers to the heart, and “infarction” means death of tissue due to lack of blood supply.

About Heart Attacks
Your heart muscle needs oxygen to survive. A heart attack occurs when the blood flow that brings oxygen to the heart muscle is severely reduced or cut off completely. This happens because coronary arteries that supply the heart muscle with blood flow can slowly become narrow from a buildup of fat.

Warning Signs of a Heart Attack
Some heart attacks are sudden and intense — the “movie heart attack,” where no one doubts what’s happening. But most heart attacks start slowly, with mild pain or discomfort. Often people affected aren’t sure what’s wrong and wait too long before getting help. Here are signs that can mean a heart attack is happening:

  1. Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness or pain.
  2. Discomfort in other areas of the upper body. Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw or stomach.
  3. Shortness of breath with or without chest discomfort.
  4. Other signs may include breaking out in a cold sweat, nausea or lightheadedness.

New technology

If there is a clot during heart attack, new devices have come to remove clots. For the narrowing in the arteries, still need to do either angioplasty with drug eluting stents or by bypass surgery. Many types of stents have come-recent being bio-absorbable stent which gets dissolved over a course of time without leaving any foreign body.
