A heart attack, or myocardial infarction, occurs when blood flow to the heart is blocked. A heart attack can permanently damage the heart muscle. It is a life-threatening condition.
Call 911 if you or someone you are with is having a heart attack.

Heart Attack Symptoms
Heart attack symptoms may be sudden or come on gradually over the course of a day, several days, or even weeks.
Call 911 if you or someone near you experiences:
- Feelings of pain, fullness, squeezing, pressure, or burning in the chest that may move to the arms, shoulders, jaw, belly, or back
- Difficulty breathing or shortness of breath
- Cold sweats
Keep in mind that, in addition to chest pain, women are more likely to experience subtle symptoms such as fatigue and nausea when having a heart attack.
Early heart attack treatment can prevent long-term disability, preserve heart function, and save your life.
Causes of Myocardial Infarction
A block in blood flow to the heart means the heart receives less oxygen. Without oxygen and other nutrients, heart cells start to die. This leads to a heart attack.
Different reasons for blocked or reduced blood flow to the heart include:
- Blood clots and plaque buildup in the coronary arteries — the most common cause of heart attack
- Spontaneous coronary artery dissection, an abrupt tear in the coronary artery that traps blood and blocks more blood flow through the artery to the heart
- Spasm of a coronary artery, narrowing the artery, blocking or slowing blood flow

Diagnosing Heart Attack
Doctors use several tests to diagnose a heart attack and assess damage:
- Electrocardiogram (EKG or EGC) shows your heart’s rate, rhythm, and electrical activity.
- Blood tests detect proteins released by damaged heart muscle.
- Coronary angiography looks for artery blockages using X-rays and dye injections.
- Echocardiogram and 3D echocardiogram are ultrasound tests that show heart function and structure.
- Chest X-ray can find extra heart fluid or heart enlargement, both of which can be signs of heart disease or damage.
