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, jaw, or stomach.
• Shortness of breath, which often comes with chest discomfort but can occur before the chest discomfort.
• Other signs such as breaking out in a cold sweat, nausea, or lightheadedness.

Sometimes people who are having a heart attack do not have the usual symptoms, resulting in a delay in care. Other symptoms may include abdominal pain, nausea, trouble breathing, and unexplained fatigue.

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.
