Every second counts during a heart attack. Recognizing the warning signs and acting quickly can mean the difference between life and death.

Heart Attack First Aid – 5 Essential Steps to Save a Life

Heart Attacks Explained: What to Do in an Emergency

1. Call Emergency Services Immediately

The first and most crucial step is to call your local emergency number (for example, 911 in the U.S.). Every minute counts during a heart attack. Prompt medical attention can save lives and reduce heart damage.

• While waiting for help to arrive:
• Stay on the line with the operator and follow any instructions.
• Give clear information: location, condition of the patient, and any known medical history.

If possible, alert someone nearby to assist you or guide emergency responders.

2. Keep the Person Calm and Seated

Once help is on the way, it’s essential to keep the person calm and seated. Stress and movement can increase the strain on the heart.
Helpful tips:

• Have them sit upright in a chair, or lie down with knees bent if they feel faint.
• Loosen tight clothing around the chest and neck.
• Encourage slow, deep breaths to reduce anxiety.

Avoid giving the person food or drinks (except approved medications like aspirin, if safe). Comforting words and presence can significantly reduce panic and help them stay still until help arrives.

3. Offer Aspirin, if Available and Appropriate

Chewing one regular-strength aspirin can sometimes help during a heart attack by preventing blood clots from worsening. However, only give aspirin if:

• The person is conscious and able to chew.
• They are not allergic to aspirin.
• A doctor has not advised against aspirin in their medical history.

Do not give aspirin if the patient has a known bleeding disorder, recent surgery, or other contraindications. When in doubt, wait for guidance from emergency services.

4. Monitor Breathing and Responsiveness

While waiting for professional help:

• Check if the person is breathing normally and remains responsive.
• If they become unconscious and stop breathing, immediately start CPR (cardiopulmonary resuscitation) if you are trained.
• If an AED (Automated External Defibrillator) is available, use it according to instructions.

Prompt CPR and AED use can significantly improve survival rates during cardiac arrest. Remember, even untrained rescuers can perform “hands-only CPR” — pushing hard and fast in the center of the chest until help arrives.

5. Stay With the Person Until Help Arrives

Never leave a heart attack patient alone. Your presence:

• Provides reassurance.
• Allows immediate response if their condition changes.
• Helps emergency responders quickly assess and assist when they arrive.

Keep monitoring their condition, stay calm, and follow any instructions provided by the emergency operator. Your quick, composed actions are just as important as calling for help.

Final Thoughts 

Knowing these five essential steps — call for help, keep calm, offer aspirin safely, monitor breathing, and stay with the patient — can save lives during a heart attack. Quick action and proper first aid significantly improve survival and recovery chances.
