What Happens During a Heart Attack?

WRITTEN BY: Xuan Pham

Heart-related diseases are the number one killer of men and women in the US. In particular to heart attacks, this condition claims the lives of 7 million people annually. But while we have all been conditioned to understand that a heart attack is a serious health threat that requires immediate medical intervention, what exactly goes on in the body during this event?

Fundamentally, a heart attack occurs when blood flow to a section of the heart is interrupted due to some obstruction. When this happens, that part of the heart can't get oxygen and becomes damaged. And because the heart is a vital organ that pumps blood to the rest of the body, a heart attack is no joking matter. Watch the video to learn more about what goes on in the body during a heart attack, and the risk factors for this condition.
