1.Clogged Arteries
A buildup of sticky plaque (fat and cholesterol) can narrow your heart’s arteries, making it harder for blood to pass through. Many people don’t even know there’s a problem until an artery is clogged by a blood clot and they have a heart attack. But there may be warning signs of coronary artery disease, like frequent chest pain called angina.
2.Inside a Heart Attack
Plaque is hard on the outside and mushy on the inside. Sometimes that hard outer shell cracks. When this happens, a blood clot forms. If it completely blocks your artery, it cuts off the blood supply to part of your heart. Blood carries oxygen, and a shortage of that can quickly damage the organ and possibly kill you. The attack is sudden, and it’s important to get medical help right away.
