• Signs of a heart attack include chest pain that may also spread to the back, shoulders, arms, neck, or jaw. You may have other heart attack symptoms, such as shortness of breath, nausea, sweating, or dizziness. Symptoms vary, and some people experience no symptoms. It is important to know the signs of a heart attack so you can act quickly to get treatment.
   
• Unfortunately, many heart attack victims wait two hours or more after their symptoms begin before they seek medical help. This delay can result in death or lasting heart damage.
   
• The amount of damage sustained from a heart attack depends on how much of the heart is affected, how soon treatment begins, and other factors.
   

• Diagnosis and treatment of a heart attack can begin when emergency medical personnel arrive after you call 911. At the hospital emergency room, doctors will work fast to find out if you are having or have had a heart attack and give you treatment.
   
• If you are having a heart attack, doctors will work quickly to restore blood flow to the heart and continuously monitor vital signs to detect and treat complications.
   
• Long-term treatment after a heart attack may include cardiac rehabilitation, checkups and tests, lifestyle changes, and medications.
   

• After a heart attack, most people are able to return to their normal activities. Ask your doctor when you should return to driving, physical activity, work, sexual activity, strenuous activities, and air travel.
   
• If you have had a heart attack, it is very important to have an emergency action plan in case of another heart attack. Talk to your doctor about your plan and make sure that your family members understand it.
