What Happens During a Heart Attack
The term “heart attack” is kind of a misnomer. Nothing actually attacks your heart. So, what really happens during a heart attack?
In a nutshell, a coronary artery becomes blocked. This prevents blood from flowing to the heart, and as a result your heart muscle is damaged.
The medical term is myocardial infarction. "Myo" means muscle. "Cardial" refers to the heart. "Infarction" means tissue death due to lack of blood supply. Myocardial infarction and heart attack mean the same thing.
