english: Heart attacks occur for many reasons, but most often, they occur when arteries get clogged, blood flow is cut off and oxygen-starved cells in the heart muscles start to die.
non_english: Infarkti se dešavaju iz mnogo razloga, ali najčešće, kada se arterije začepe, dotok krvi se prekine i ćelije srčanih mišića bez kiseonika počinju da odumiru.
