Heart Attack Symptoms: What Does a Myocardial Infarction Feel Like?

A heart attack, or myocardial infarction, typically occurs when there is a blockage in one of the heart's major blood vessels. The heart is supplied by three main coronary arteries: the right coronary artery, the left anterior descending artery, and the left circumflex artery. When one of these arteries becomes obstructed, it can lead to the death of heart muscle tissue, which in turn causes a range of symptoms.

Common Signs and Sensations of a Heart Attack

One of the most common symptoms is a feeling of pressure, tightness, or a tearing sensation in the center or upper part of the chest. This discomfort is often described as if a heavy weight is pressing down on the chest. The pain may radiate to other areas of the body, including the back, throat, jaw, and even the inner side of the left arm.

Distinguishing Features of Heart Attack Pain

Unlike typical chest discomfort, heart attack symptoms tend to last for an extended period—often more than a few minutes—and are not relieved by taking nitroglycerin. In many cases, individuals may also experience additional symptoms such as nausea, vomiting, excessive sweating, and a pale or grayish complexion. These signs should not be ignored, as they indicate a medical emergency.

What to Do If You Suspect a Heart Attack

If you or someone around you is experiencing these symptoms, it's crucial to seek immediate medical attention. Time is of the essence when it comes to treating a heart attack, and getting to the nearest hospital as quickly as possible can significantly improve outcomes and reduce the risk of long-term complications.
