Chest pain, trouble breathing, lightheadedness—the symptoms of a heart attack are familiar to most people. But many of us don’t realize what exactly is happening to the body during a heart attack. The better you understand what a heart attack does to your heart, the more prepared you will be should it actually happen to you or someone near you.
How a heart attack begins. A heart attack happens when there is a blockage in one of your coronary arteries, the blood vessels that bring blood to your heart and permit it to continue functioning. With the flow of blood blocked, the tissue in your heart muscle begins to die. Without quick medical attention, your heart may suffer permanent—and potentially fatal—damage.
What causes a heart attack? In many cases, a heart attack is the result of coronary artery disease, a condition that happens when your coronary arteries gradually become blocked by cholesterol and plaque. Plaque is a sticky material formed of cellular waste and other substances that become trapped in your blood vessels. Heart attacks can also happen when your arteries suddenly tighten, or spasm, cutting off blood flow.
What happens after a heart attack? If medical professionals are able to successfully open the blocked artery, your heart will slowly begin repairing itself. Since the damaged tissue will be replaced with scar tissue, however, your heart may be weaker than it was before the attack. The faster your heart attack is attended to, the better the odds are of reducing damage to your heart.
