What is a common symptom of myocardial infarction?

Chest pain or discomfort is a hallmark symptom of myocardial infarction (MI), commonly referred to as a heart attack. The pain may feel like a sense of pressure, squeezing, fullness, or aching in the center or left side of the chest. It can vary in intensity and may come and go. This symptom is usually caused by reduced blood flow to the heart muscle due to a blockage in one or more of the coronary arteries, leading to ischemia and, if not resolved quickly, ultimately resulting in muscle damage.

While other symptoms can accompany a myocardial infarction, such as dizziness, nausea, or even nonspecific discomfort in other areas of the body (like the arms, back, neck, jaw, or stomach), chest pain or discomfort stands out as the most universally recognized and classic symptom. Understanding this can help in the swift identification and treatment of MI, which is critical in minimizing heart damage and improving outcomes for affected individuals.
