First Aid for Heart Attack: What to Do?

Reading Time: 15 minutes

A heart attack, also known as a myocardial infarction, is a life-threatening medical emergency that requires immediate action. Knowing how to recognize the signs and administer the right first aid can significantly increase the chances of survival and reduce the risk of permanent damage. In this article, we will explore the signs of a heart attack, step-by-step first aid procedures, and essential actions to take when someone is experiencing a heart attack.

What Is a Heart Attack?

A heart attack occurs when one of the coronary arteries becomes blocked, interrupting the blood flow to the heart. This blockage deprives the heart muscle of oxygen, leading to damage or death of the tissue. A heart attack can happen suddenly or develop over time, often due to the build-up of fatty deposits (plaque) in the arteries, a condition known as atherosclerosis.

Common Symptoms of a Heart Attack

Recognizing the symptoms of a heart attack early is crucial for timely intervention. The following are common signs that someone may be experiencing a heart attack:

  • Chest Pain or Discomfort: A heavy, squeezing, or pressure-like sensation in the center of the chest that lasts more than a few minutes or goes away and comes back.
  • Pain in Other Areas of the Body: Pain or discomfort may radiate to the arms, shoulders, back, neck, jaw, or stomach.
  • Shortness of Breath: Difficulty breathing, especially during physical activity or while at rest.
  • Nausea or Lightheadedness: Feeling nauseous, dizzy, or faint can accompany a heart attack.
  • Cold Sweat: Sweating profusely without physical exertion.
  • Fatigue: Unusual tiredness or weakness, sometimes experienced even without physical exertion.

If you notice any of these symptoms in someone, it's important to take immediate action, as early intervention can be life-saving.

First Aid Steps for Heart Attack

If you or someone around you is experiencing a heart attack, following these first aid steps can make a crucial difference. Prompt intervention can improve the chances of survival and reduce complications.

1. Call for Emergency Help

The very first step is to call emergency services immediately (e.g., 911 in the United States, 112 in Europe). A heart attack is a medical emergency that requires professional intervention. The sooner help arrives, the better the chances of recovery.

While waiting for emergency help to arrive, it's essential to stay as calm as possible. If the person is conscious, reassure them that help is on the way.

2. Administer Aspirin (If Appropriate)

If the person is conscious and not allergic to aspirin, offer them a dose of aspirin (usually 300 mg). Aspirin helps thin the blood and can assist in dissolving the clot causing the blockage in the coronary artery. However, aspirin should not be given if the person has a known allergy or if they are already on blood thinners prescribed by a doctor. Always check with the individual about their medical history before administering aspirin.

3. Encourage the Person to Rest and Stay Calm

It’s vital to keep the person as calm as possible to avoid further stress on their heart. They should sit down and rest in a comfortable position, ideally leaning back slightly with their legs elevated. Try to keep them relaxed, as anxiety can worsen the condition by increasing the heart rate and blood pressure.

4. Perform CPR if the Person Becomes Unconscious and Stops Breathing

If the person loses consciousness and is not breathing, cardiopulmonary resuscitation (CPR) is essential. CPR can help maintain blood circulation and keep oxygen flowing to the brain and other vital organs until emergency medical help arrives.

  • Step 1: Call for help. If no one else is around, make sure you call emergency services before starting CPR.
  • Step 2: Check the person’s pulse and breathing. If the person has no pulse and is not breathing, begin CPR immediately.
  • Step 3: Place the person on their back on a firm surface.
  • Step 4: Begin chest compressions. Place your hands, one on top of the other, on the center of the person’s chest. Press down hard and fast (about 100-120 compressions per minute), allowing the chest to rise fully between compressions.
  • Step 5: If trained, provide rescue breaths. After 30 compressions, give two rescue breaths by tilting the person’s head back and sealing your mouth over theirs. Continue alternating 30 chest compressions and 2 rescue breaths until emergency responders arrive.
5. Use an Automated External Defibrillator (AED) If Available

If an AED is nearby, use it as soon as possible. An AED can analyze the heart’s rhythm and deliver a shock if needed to restore normal heart activity. Follow the machine’s voice prompts to ensure you are using it correctly.

6. Monitor the Person’s Condition

Even after administering first aid, you must continue monitoring the person’s condition. If they regain consciousness, continue to reassure them and ensure they stay as calm as possible. If their condition worsens or they stop breathing, continue CPR until professional help arrives.

When to Perform CPR

It’s essential to perform CPR if the person loses consciousness and stops breathing. The following are indications that CPR should be initiated:

  • The person collapses and does not respond.
  • There is no breathing or irregular breathing (gasping).
  • No pulse is detected.

Performing CPR can significantly improve the chances of survival, especially if done quickly and correctly.

The Importance of Quick Action

Time is of the essence during a heart attack. The faster medical intervention is provided, the better the chances of recovery. The first few minutes after a heart attack are critical, as early treatment can prevent permanent heart damage, restore normal heart function, and improve overall outcomes.

By recognizing the symptoms, administering aspirin (if appropriate), staying calm, performing CPR, and using an AED, you can make a life-saving difference while waiting for emergency responders.

Prevention of Heart Attacks

While it is not always possible to prevent a heart attack, adopting a heart-healthy lifestyle can reduce the risk. Here are some tips for maintaining heart health:

  • Maintain a Healthy Diet: Eat a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats.
  • Exercise Regularly: Engage in physical activity for at least 30 minutes a day to improve cardiovascular health.
  • Avoid Smoking: Smoking is a major risk factor for heart disease, so quitting can significantly reduce the risk of a heart attack.
  • Monitor Blood Pressure and Cholesterol Levels: Regular check-ups can help detect and manage high blood pressure or high cholesterol levels.
  • Manage Stress: Chronic stress can increase the risk of heart disease, so stress management techniques such as mindfulness, meditation, and relaxation exercises are beneficial.

Conclusion

A heart attack is a serious medical emergency that requires immediate intervention. Knowing the symptoms, staying calm, and taking the appropriate first aid steps—such as calling for help, administering aspirin (if appropriate), and performing CPR—can save lives. Quick action can make all the difference, so be sure to act promptly and confidently in the event of a heart attack.
