How To Treat a Heart Attack – First Aid Guidelines

Posted on by

Heart attacks can happen suddenly and without warning. Knowing how to recognise the signs and respond effectively can save a life. A heart attack occurs when there is a blockage in the arteries supplying blood to the heart, leading to a risk of serious heart damage or cardiac arrest. At Coastal First Aid, we follow the latest Australian and New Zealand Committee on Resuscitation (ANZCOR) Guidelines to provide the most up-to-date and effective first aid advice.

You can access the full ANZCOR guideline here: ANZCOR Guideline 9.2.1 – Recognition and First Aid Management of Suspected Heart Attack.

The Basics of Heart Attack First Aid

When someone is having a heart attack, every minute counts. ANZCOR recommends that you follow these essential steps:

1. Recognise the Symptoms

A heart attack can present with various warning signs, including:

  • Pain or discomfort in the chest, neck, jaw, arms, or back.
  • Shortness of breath.
  • Pale, clammy skin.
  • Nausea or vomiting.
  • Dizziness or light-headedness.
  • Sweating or feeling faint.

The pain may feel like tightness, heaviness, or pressure in the chest, and it may come on suddenly or gradually. Some people, including the elderly, women, and those with diabetes, may experience atypical symptoms, such as shortness of breath or mild discomfort instead of severe chest pain.

2. Encourage the Person to Rest

  • Stop all activity and help them sit or lie down in a comfortable position.
  • Reassure them and keep them as calm as possible.

3. Call Emergency Services (000 in Australia)

  • If the symptoms are severe, getting worse, or lasting longer than 10 minutes, call an ambulance immediately.
  • Do not wait for the symptoms to go away—early medical treatment can prevent further heart damage.

4. Assist with Medication (if applicable)

  • If the person has been prescribed heart medication (such as an angina spray or tablets), help them take it as directed.
  • ANZCOR recommends giving 300 mg of aspirin, if available, unless the person has an allergy to aspirin.

5. Monitor the Person and Be Prepared for CPR

  • Stay with the person until the ambulance arrives.
  • If they become unresponsive and stop breathing, begin CPR immediately and use an Automated External Defibrillator (AED) if available.

The Importance of First Aid Training

Heart attacks are a leading cause of sudden death, and fast first aid intervention can save lives. Enrolling in a first aid course can give you the confidence and skills to act effectively in an emergency.

  • Recognise the signs early – Many people dismiss heart attack symptoms as minor discomfort. Training helps you identify warning signs quickly.
  • Know how to respond – Proper training teaches you how to provide first aid, including positioning, medication assistance, and calling for help.
  • Learn life-saving CPR and AED use – If a heart attack leads to cardiac arrest, knowing CPR and how to use a defibrillator can make all the difference.
  • Be prepared in any setting – Whether at home, work, or in public, knowing what to do can help protect your family, friends, and colleagues.
