What is Myocardial Infarction in Medical Terms?

Myocardial Infarction (MI), commonly known as a heart attack, occurs when blood flow to a part of the heart muscle is blocked for an extended period, causing damage or death to the affected heart tissue. The blockage typically happens due to the buildup of plaque (a combination of fat, cholesterol, and other substances) in the coronary arteries, which supply oxygen-rich blood to the heart. When the plaque ruptures, a blood clot forms, further obstructing blood flow.

Types of Myocardial Infarction:

  • ST-Elevation Myocardial Infarction (STEMI): A severe form of heart attack characterized by a significant blockage in a coronary artery, typically visible on an electrocardiogram (ECG) as an elevated ST segment.
  • Non-ST-Elevation Myocardial Infarction (NSTEMI): A less severe form, where the blockage is partial or temporary, but still causes damage to the heart muscle.

If you experience chest pain or other symptoms of a heart attack, it is critical to seek emergency medical attention immediately to improve outcomes and prevent further complications.
