Time is muscle when you’re having a heart attack. The sooner you call 911, the more likely it is you will survive your heart attack without serious damage to your heart. In many communities, emergency responders are trained to take suspected heart attack patients straight to a hospital that is a designated center for heart care. That might not be the closest hospital, but it is the one that is best equipped to treat a heart attack in the fastest, safest, and most effective way.
If you get to the right hospital within an hour of having symptoms, your chances of surviving a heart attack are very high. Every minute of delay after that, however, makes death or serious heart damage much more likely. If you want to live, call 911.
