How long can a heart attack last before it kills you? My father recently passed away after a heart attack. I'm not sure if someone had gotten to him sooner if he'd still be alive? I've heard many people have survived after a heart attack. Can some kill you in as little as 5-15 minutes, or does it take an hour. I am really concerned and I don't want it to eat away at me. Thank you for your information it means so much to me.

Once the blood has stopped flowing to the brain, within couple of minutes total necrosis of the cerebral neurons begins occurring very rapidly and is irreversible. Now, a heart attack is when an area of the heart is not getting enough blood flow and dies, compared to a cardiac arrest, which is essentially when the heart stops beating. So, if your father's heart had chances to be revived by defibrillation or other mechanism even after 5-15 minutes, there would have been no chance for his brain to take over the control of his body's functions. Good Health!
