Heart Attack: Early Warning Signs

Heart attacks are the most common cause of death in the US. Heart attacks occur when there is a sudden, complete blockage of blood flow to part of the heart muscle. Every minute of the day someone dies from a heart attack. Early treatment is crucial for someone who is having a heart attack. Quick treatment to break up blood clots can greatly improve a person's chance of surviving a heart attack. Since early treatment makes a difference, it is important to know the early signs of a heart attack.

What are the signs of a heart attack?

Not everyone has the same symptoms. Signs of a heart attack may be one or more of the following:

• Discomfort in the center of the chest that lasts for more than 5 minutes, or that goes away and comes back. It can feel like uncomfortable pressure, squeezing, fullness, or pain.
• Discomfort in other areas of the upper body, such as pain or discomfort in one or both arms, the back, neck, or jaw.
• Shortness of breath, which you may have before you feel chest discomfort.
• Other signs, such as breaking out in a cold sweat or feeling lightheaded or nauseous.

Sometimes people who are having a heart attack delay getting care because they have different symptoms, like abdominal pain or unexplained tiredness. Because they may not have chest pain, someone who is having these symptoms may not think that they are having a heart attack. They may think they have indigestion and not get medical help as soon as they should.

What should I do in case of a heart attack?

If you or someone you know feels chest discomfort, especially with one or more of the other symptoms, get medical care right away. Do not wait longer than 5 minutes before calling 911. Calling 911 is usually the fastest way to get medical help in an emergency.

If you think a person is having a heart attack:

• Call for emergency help by dialing 911. Stay on the line. Do not take the person to a hospital in your own car.
• Be calm and take actions that make the person feel less excited.
• Have the person sit or lie down.
• Ask the person if they take any medicines for chest pain, such as nitroglycerin. If so, get it and follow the written instructions on its use.
• Ask the person if they are allergic to aspirin. If they are not allergic, have them chew an aspirin as soon after calling 911 as possible.
• If the person stops breathing, start mouth-to-mouth resuscitation. Tell the 911 operator that this has happened.
• If the pulse and breathing stop, begin CPR. Continue until help arrives.
