Basic First Aid Actions That Can Help in the Event of a Heart Attack: 3 Important Recommendations
A heart attack is one of the most serious medical emergencies a person can experience. Every year, millions of people around the world suffer from heart attacks, and many lives are saved because someone nearby recognized the warning signs and acted quickly. While professional medical treatment is essential, the first few minutes before emergency responders arrive can significantly influence the outcome.
Knowing what to do—and what not to do—can help reduce complications, improve survival rates, and provide comfort to the affected person until medical professionals take over.
This comprehensive guide explains three essential first aid recommendations that everyone should know. Whether you're at home, at work, or in a public place, these simple yet effective actions can make a meaningful difference during a heart attack emergency.
Understanding a Heart Attack
Before discussing first aid, it's helpful to understand what a heart attack actually is.
A heart attack (also called a myocardial infarction) occurs when blood flow to part of the heart muscle becomes blocked. Without oxygen-rich blood, heart muscle cells begin to die. The longer the blockage remains untreated, the greater the damage to the heart.
Most heart attacks occur because a blood clot forms in a coronary artery that has been narrowed by fatty deposits (plaque). Immediate medical treatment is necessary to restore blood flow.
Common Signs and Symptoms of a Heart Attack
Recognizing symptoms quickly is the first step toward saving a life.
Typical warning signs include:
- Chest pain or pressure
- Tightness or squeezing sensation in the chest
- Pain spreading to the left arm, both arms, neck, jaw, shoulders, or back
- Shortness of breath
- Cold sweat
- Nausea or vomiting
- Lightheadedness
- Sudden weakness
- Unusual fatigue
- Anxiety or a feeling of impending doom
It's important to know that not everyone experiences severe chest pain. Women, older adults, and people with diabetes may have more subtle symptoms such as fatigue, nausea, dizziness, or back pain.
Whenever a heart attack is suspected, it's safest to treat the situation as an emergency.
Why Immediate Action Matters
Time is critical during a heart attack.
Medical experts often say, "Time is muscle." Every minute that blood flow remains blocked increases damage to the heart muscle.
Prompt treatment can:
- Reduce heart damage
- Improve survival
- Lower the risk of heart failure
- Prevent life-threatening complications
- Increase the chances of a full recovery
The actions taken by bystanders before emergency services arrive can have a major impact.
Recommendation 1: Call Emergency Medical Services Immediately
The most important first aid action is calling emergency medical services (EMS) as soon as heart attack symptoms appear.
Do not wait to see whether the symptoms disappear.
Many people delay seeking help because they believe the pain is simply indigestion, muscle strain, or stress. Unfortunately, this delay can become life-threatening.
Why Calling Emergency Services Is Essential
Emergency responders can:
- Begin treatment immediately
- Monitor heart rhythm
- Administer oxygen if needed
- Provide life-saving medications
- Perform CPR if necessary
- Use a defibrillator if cardiac arrest occurs
- Transport the patient safely to a hospital
Driving yourself to the hospital is usually not recommended because the person's condition may suddenly worsen.
What to Tell the Emergency Dispatcher
Remain as calm as possible and provide:
- Exact location
- Patient's age (if known)
- Symptoms being experienced
- Time symptoms began
- Whether the person is conscious
- Whether they are breathing normally
- Any known medical conditions
Follow the dispatcher's instructions carefully.
Stay With the Person
After calling emergency services:
- Stay nearby.
- Keep the person calm.
- Monitor breathing.
- Observe any changes in condition.
- Be prepared to begin CPR if instructed or if the person becomes unresponsive and is not breathing normally.
Never leave the person alone unless absolutely necessary.
Recommendation 2: Help the Person Rest and Keep Them Calm
Physical activity increases the heart's demand for oxygen, which can worsen heart damage during a heart attack.
Helping the person rest is one of the simplest and most effective first aid measures.
Encourage the Best Position
A comfortable position can reduce strain on the heart.
Many people feel better when:
- Sitting upright
- Leaning slightly backward
- Supporting the back with cushions
- Keeping knees bent
If sitting is uncomfortable, allow the person to choose whichever position feels easiest for breathing.
Avoid making them lie completely flat unless they become unconscious.
Loosen Tight Clothing
Tight clothing can increase discomfort.
Loosen:
- Ties
- Scarves
- Tight collars
- Belts
- Jackets
Ensure fresh air is available if possible.
Keep the Environment Calm
Stress and panic can increase heart rate and blood pressure.
Speak slowly.
Offer reassurance without making promises about the outcome.
Avoid creating unnecessary noise or crowding around the patient.
If many people are present, ask others to step back to provide space.
Do Not Allow Physical Activity
Do not encourage the person to:
- Walk
- Climb stairs
- Drive
- Carry objects
- Continue working
Even if symptoms improve, they still require immediate medical evaluation.
Recommendation 3: Assist With Aspirin If Appropriate and Be Ready for CPR
Once emergency services have been called and the person is resting, there are two additional actions that may help depending on the situation.
Aspirin May Help
If the person:
- Is conscious
- Is able to swallow
- Is not allergic to aspirin
- Has not been told by a healthcare professional to avoid aspirin because of conditions such as active bleeding
A dispatcher or healthcare professional may advise chewing a regular aspirin (commonly 160–325 mg, depending on local guidance and available tablets).
Chewing allows the medication to work more quickly than swallowing it whole.
Aspirin helps reduce blood clot formation, which may improve blood flow to the heart.
However, aspirin is not appropriate for everyone, so it should not be given if there is a known allergy, signs of significant bleeding, or another medical reason to avoid it. When in doubt, follow the instructions of emergency medical services.
If the Person Has Prescribed Nitroglycerin
Some people with known heart disease carry prescribed nitroglycerin.
If they have their own medication:
- Help them take it exactly as prescribed.
- Do not give someone else's medication.
- Do not administer additional doses beyond the prescribed instructions unless directed by medical professionals.
Monitor Continuously
Watch for changes in:
- Breathing
- Consciousness
- Skin color
- Ability to speak
Report any significant changes to emergency responders when they arrive.
Be Prepared to Perform CPR
A heart attack can sometimes lead to cardiac arrest.
Signs include:
- Collapse
- Loss of consciousness
- No normal breathing
- No response
If this happens:
- Call emergency services if this has not already been done.
- Begin chest compressions immediately if you are trained—or if instructed by the emergency dispatcher.
- If an automated external defibrillator (AED) is available, use it as soon as possible by following its voice prompts.
High-quality CPR helps circulate blood to the brain and other vital organs until professional help arrives.
What You Should NOT Do During a Heart Attack
Knowing what to avoid is just as important as knowing what to do.
Avoid these common mistakes:
Do not ignore symptoms.
Even mild chest discomfort can signal a serious problem.
Do not wait for symptoms to disappear.
Prompt treatment offers the best chance of limiting heart damage.
Do not let the person drive.
Their condition could deteriorate suddenly.
Do not force food or drinks.
Unless specifically advised (for example, with appropriate aspirin), avoid giving food or beverages, especially if the person feels nauseated or has difficulty swallowing.
Do not give unprescribed medications.
Only assist with medications that are prescribed for that individual or recommended by emergency medical personnel.
Do not allow strenuous activity.
Rest is essential until professional help arrives.
Who Is Most at Risk?
Certain factors increase the likelihood of a heart attack.
Risk factors include:
- High blood pressure
- High cholesterol
- Smoking
- Diabetes
- Obesity
- Physical inactivity
- Family history of heart disease
- Older age
- Chronic stress
- Excessive alcohol consumption
- An unhealthy diet
Although these factors increase risk, heart attacks can occur in people without obvious risk factors.
Preventing Heart Attacks
While not all heart attacks are preventable, healthy lifestyle choices can substantially reduce risk.
Helpful habits include:
- Exercising regularly
- Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins
- Maintaining a healthy weight
- Avoiding tobacco
- Limiting alcohol
- Managing blood pressure and cholesterol
- Controlling diabetes
- Getting adequate sleep
- Managing stress
- Attending regular medical checkups
People with known heart disease should also take prescribed medications as directed and discuss an emergency action plan with their healthcare provider.
Frequently Asked Questions
Can a heart attack go away on its own?
Symptoms may lessen temporarily, but the underlying problem can still be life-threatening. Always seek emergency medical care if a heart attack is suspected.
Should someone cough repeatedly during a heart attack?
The idea of "cough CPR" is widely misunderstood. It is not recommended as a self-treatment for someone experiencing the symptoms of a heart attack outside of a monitored medical setting.
Is every chest pain a heart attack?
No. Chest pain can have many causes, including muscle strain, acid reflux, anxiety, or lung conditions. However, because it is difficult to distinguish these without medical evaluation, chest pain—especially when accompanied by other warning signs—should be treated as a medical emergency.
What if symptoms disappear?
Even if symptoms improve after a few minutes, the person should still be evaluated urgently by healthcare professionals. Temporary improvement does not rule out a heart attack.
Final Thoughts
A heart attack is a medical emergency that demands immediate action. While only healthcare professionals can provide definitive treatment, the steps taken by bystanders in the first few minutes can make a significant difference.
The three most important first aid recommendations are:
- Call emergency medical services immediately at the first sign of a possible heart attack.
- Help the person rest and stay calm, keeping physical exertion to a minimum while monitoring their condition.
- Assist with appropriate first aid, such as helping with prescribed medication or dispatcher-recommended aspirin when appropriate, and be ready to perform CPR and use an AED if the person becomes unresponsive and is not breathing normally.
Learning these basic first aid actions equips you to respond confidently in an emergency. Combined with rapid access to professional medical care, these measures can improve the chances of survival and recovery for someone experiencing a heart attack.
