Definition & Meaning of "myocardial infarction"

What is a "myocardial infarction"?

A myocardial infarction, commonly known as a heart attack, occurs when there is a sudden blockage of blood flow to a part of the heart muscle, leading to damage or death of the affected tissue. This blockage is usually caused by the bursting of a fatty buildup in the coronary arteries, resulting in the formation of a blood clot. Symptoms of a myocardial infarction include chest pain or discomfort, shortness of breath, nausea, lightheadedness, and pain or discomfort in the arms, back, neck, or jaw. Immediate medical attention is crucial during a myocardial infarction to prevent further damage to the heart muscle and improve outcomes. Treatment may involve medications to dissolve blood clots, procedures such as angioplasty to restore blood flow, and lifestyle changes to reduce the risk of future heart problems.
