If you think you or someone you know is experiencing a heart attack, here are your first steps:
1) Call 911!
In almost all cases, calling 911 is the fastest way to get lifesaving treatment. It is unsafe for you to drive yourself if you suspect you are having a heart attack in case you lose the ability to drive, and most ambulances can reach your home faster than you could drive yourself to the hospital. If someone you know is experiencing a heart attack, call 911 and stay with that person until help arrives.
2) Learn CPR/Encourage Others to Learn
If you wish to be resuscitated (brought back to life) and want life-saving measures to be done in case you are unresponsive, make that clear to those close to you and encourage them to learn CPR. If you experience a heart attack and become unresponsive having someone nearby who knows CPR can save your life. In turn, if someone you know is unresponsive and you feel comfortable, learning CPR can enable you to help save someone's life.
