What To Do

What To Do If Someone Has a Heart Attack at Home

Key Takeaway: If someone at home has chest pain or pressure that may be a heart attack, stop activity, call 000 for an ambulance, keep them resting, and chew 300 mg aspirin if they are not allergic and have not been told not to take it. If they collapse and stop breathing normally, start CPR.

At home, people often lose time debating whether it is indigestion, looking for car keys, or planning to drive themselves to hospital. That delay can do more damage than the distance to the hospital.

🚨 What To Do Immediately

1. Stop what they are doing and sit them down

Healthdirect’s chest pain advice says chest pain should be considered heart-related until proven otherwise. Get them to rest straight away. Do not encourage them to walk it off, shower, or “see if it passes”.

2. Call 000 for an ambulance

Call early if the pain is severe, getting worse, or lasts more than 10 minutes. The Heart Foundation and Better Health Channel both stress that every minute counts in a heart attack.

3. Help with prescribed angina medicine if they already have it

If they have been prescribed angina spray or tablets, help them take it exactly as directed while they rest. Do not guess doses or use somebody else’s medicine.

4. Chew 300 mg aspirin if it is safe for them

Healthdirect and Better Health Channel both advise chewing 300 mg aspirin while waiting for the ambulance, unless the person is allergic to aspirin or has been told by a doctor not to take it.

5. Keep them calm, resting, and under watch

Loosen tight clothing, reassure them, and note when symptoms started. Do not give food or drink. If they become drowsy but are still breathing normally, be ready to place them in the recovery position.

📞 Call 000 and Ask for an Ambulance

Do not drive them yourself unless there is absolutely no ambulance option. The Heart Foundation says an ambulance is the safest and quickest way to treatment, because care starts when the crew arrives and they can tell you what to do next. That can include aspirin if it is appropriate.

• Say you think it may be a heart attack
• Give the exact address and best entry point to the home
• Say whether the person is conscious and breathing normally
• Tell them when the pain or pressure started and whether it is getting worse
• Mention prescribed angina medicine, aspirin allergy, diabetes, or recent collapse if relevant

Healthdirect’s 000 guide says to stay on the line until the operator tells you to hang up. If the person collapses or breathing changes while you are waiting, update the operator immediately.

🏠 Why a Heart Attack at Home Can Be More Dangerous

At home, the big risk is delay. People often want to finish what they were doing, lie down “for a minute”, take an antacid, or drive themselves to hospital. That wasted time can cost heart muscle.

The home setting also creates practical problems: locked doors, stairs, pets, no second helper, and fewer witnesses to notice when the person suddenly gets worse. A general guide like First Aid for Heart Attack explains the overall emergency, but the at-home version is where access, delay, and staying with the person really matter.

If the person says it feels like indigestion, remember that heart attack symptoms are not always dramatic. The Heart Foundation notes that symptoms can be milder or less obvious, especially when they spread to the jaw, back, neck, or arms rather than feeling like a single crushing chest pain.

⏱️ What To Do While Waiting for the Ambulance

Keep them resting

The safest position is usually sitting upright or half sitting, wherever breathing feels easiest. Do not let them keep walking around the house.

Get the house ready for the crew

Unlock the front door, turn on outside lights if needed, move pets away, and send someone to meet the ambulance if there is another adult present.

Gather helpful details

Bring their medicines, allergies, and any known heart history to hand. Note what time symptoms started, whether angina medicine was taken, and whether aspirin was given. That saves time once paramedics arrive.

Do not leave them alone

Heart attack symptoms can suddenly tip into collapse. Stay close enough to respond straight away if they stop answering, become very pale, or lose consciousness.

💔 If They Collapse and Stop Breathing Normally

A heart attack can lead to cardiac arrest. Our guide to heart attack vs cardiac arrest explains the difference, but the practical line is simple: if they are unresponsive and not breathing normally, start CPR now.

Call for help, follow the operator’s instructions, start chest compressions, and use an AED if one is available. If you need a refresher, our guide to CPR for adults covers the basics.

If they are unconscious but breathing normally, use the recovery position and keep checking breathing until the ambulance arrives.

🎓 Why First Aid Training Matters

Heart attack first aid feels more complicated at home because there is no clinical team, no reception desk, and no bystanders automatically stepping in. In a HLTAID011 Provide First Aid course, you practise how to recognise chest pain emergencies, call 000 clearly, use aspirin guidance safely, and move into CPR if the person collapses. That kind of first aid training makes the home setting less chaotic because you already know the sequence.
