Hello, I'm a medical professional with a strong background in cardiology. When discussing "infarction," it's important to understand that the term refers to the death of tissue in the body due to the lack of oxygen and nutrients, which is typically caused by the blockage of blood flow to that tissue.

In the context of the heart, a myocardial infarction, commonly known as a heart attack, occurs when the blood flow that brings oxygen to the heart muscle is severely reduced or blocked. This blockage is often caused by a blood clot in a coronary artery, which can lead to the death of heart muscle cells in the area served by that artery.

The severity and extent of the damage depend on the duration of the blockage and the amount of heart muscle affected. Symptoms may include chest pain, shortness of breath, nausea, and sweating. Treatment for a heart attack aims to restore blood flow as quickly as possible, often through medications or procedures such as angioplasty.
