What happens during a heart attack

    by Sur: Science

    A heart attack occurs when blood flow to part of the heart muscle is abruptly blocked, typically by a blood clot. This blockage stops oxygen from reaching the tissue, resulting in damage or death of the affected area. It is a serious medical emergency.

    Did you know just two small arteries keep your heart alive? These are the coronary arteries, and a blockage in either one can trigger a heart attack or even sudden cardiac arrest. How do they become blocked? It's often linked to plaque buildup, which narrows and hardens arteries. Eventually, the plaque can rupture, resulting in a blood clot. This cuts off the flow of nourishing blood to the heart. Without quick medical treatment, heart cells begin to die rapidly. Bye.
