Sign and Symptoms of a Heart Attack and Stroke

Signs/Symptoms of Heart Attack

If you have any of the following signs or symptoms of a heart attack, or think a friend or loved one may be having a heart attack, call 911 immediately. Do not delay getting to a hospital. Some heart attack victims will not make it alive, often because they were in denial of what was happening and waited too long. Time is essential to reduce damage to the heart muscle! Getting to a hospital also means that clot-busting medications or emergency angioplasty can reduce the damage of heart attack. This can affect the quality of the rest of your life. When it comes to heart attack symptoms, always think "better safe than sorry."


Signs of a Heart Attack

Note: Not all signs will be present. Any signs are good cause to seek immediate medical attention. Signs and symptoms may vary from person to person, and from men to women. Learn these American Heart Association signs and symptoms of heart attack:

Signs/Symptoms of a Stroke 

As with heart attack, not all symptoms of stroke may occur. Immediate medical attention is needed to prevent further damage from stroke. If you experience any of these symptoms of stroke, or see them in a friend or loved one, call 911 immediately. With new clot-busting drugs, stroke can often be "stopped in its tracks," but only if people seek immediate medical treatment.

  • Sudden numbness or weakness of the face, arm or leg, especially on one side of the body.

  • Sudden confusion, trouble speaking, or trouble understanding what others are saying.

  • Sudden trouble seeing in one or both eyes.

  • Sudden trouble walking.

  • Dizziness, loss of balance or loss of coordination.

  • Sudden, severe headache with no known cause.

Even if stroke symptoms "go away," seek medical attention immediately. Denial in the person experiencing stroke is very common. Don't take "no" for an answer.
