Heart attack first aid

Definition

A heart attack is a medical emergency.

The average person waits 3 hours before seeking help for symptoms of a heart attack. Many heart attack victims die before they reach a hospital. The sooner someone gets to the emergency room, the better the chance of survival. Prompt medical treatment also reduces the amount of damage done to the heart following an attack.

Alternative Names

First aid - heart attack; First aid - cardiopulmonary arrest; First aid - cardiac arrest

Considerations

Heart disease is the leading cause of death in America today.

Causes

A heart attack occurs when the blood flow that carries oxygen to the heart is blocked. The heart muscle becomes starved for oxygen and begins to die. See heart attack for more specific causes.

Symptoms

Heart attacks can cause a wide range of symptoms, from mild to intense. Women, the elderly, and people with diabetes are more likely to have subtle or unusual symptoms.

Symptoms in adults may include:

• Altered mental status, particularly in the elderly
• Chest pain
  • Usually in the center of the chest
  • Lasts for more than a few minutes or comes and goes
  • May feel like pressure, squeezing, fullness
  • Pain may be felt in other areas of the upper body, such as the jaw, shoulder, one or both arms, back, and stomach area
• Cold sweat
• Light-headedness
• Nausea
• Numbness, aching, or tingling in the arm (usually the left arm)
• Shortness of breath
• Weakness or fatigue, particularly in the elderly

Women are more likely than men to have symptoms of nausea, vomiting, fatigue, back or jaw pain, and shortness of breath, either alone or with chest pain.

Babies and children may appear limp and unresponsive and may have bluish-colored skin.

First Aid

1. Have the person sit down, rest, and try to keep calm.
2. Loosen any tight clothing.
3. Ask if the person takes any chest pain medication for a known heart condition.
4. Help the person take the medication (usually nitroglycerin, which is placed under the tongue).
5. If the pain does not go away promptly with rest or within 3 minutes of taking nitroglycerin, call for emergency medical help.
6. If the person is unconscious and unresponsive, call 911 (or your local emergency number), then begin CPR.
7. If an infant or child is unconscious and unresponsive, perform 1 minute of CPR, then call 911.

Do Not

• Do NOT leave the person alone except to call for help, if necessary.
• Do NOT allow the person to deny the symptoms and convince you not to call for emergency help.
• Do NOT wait to see if the symptoms go away.
• Do NOT give the person anything by mouth unless a heart medication (such as nitroglycerin) has been prescribed.

Call immediately for emergency medical assistance if

• If an adult or child is unresponsive or is not breathing.
• If sudden chest pain or other symptoms of a heart attack occur.

Prevention

Adults should take steps to control heart disease risk factors whenever possible.

• If you smoke, quit. Smoking more than doubles the chance of developing heart disease.
• Keep blood pressure, cholesterol, and diabetes in good control and follow your doctor's orders.
• Lose weight if obese or overweight.
• Get regular exercise to improve heart health. (Talk to your doctor before starting any new fitness program.)
• Eat a heart-healthy diet. Limit saturated fats, red meat, and sugars. Increase your intake of chicken, fish, fresh fruits and vegetables, and whole grains. Your health care provider can help you tailor a diet specific to your needs.
• Limit the amount of alcohol you drink. One drink a day is associated with reducing the rate of heart attacks, but two or more drinks a day can damage the heart and cause other medical problems.
