A heart attack occurs when blood flow to the heart is blocked. This blockage is most often caused by a buildup of fat, cholesterol, and other substances that form plaque inside the arteries supplying your heart (the coronary arteries).
Sometimes, a plaque can rupture and form a clot that blocks blood flow. This interruption can damage or destroy part of your heart muscle.
A heart attack—also called myocardial infarction—can be fatal, but treatments have greatly improved in recent years. That’s why it’s vital to seek emergency medical help if you suspect you’re having a heart attack.
It’s crucial to listen to your body and know the warning signs, so you can get help as quickly as possible if something’s wrong.
