Heart Alert: What are the Difference between Cardiac Arrest and a Heart Attack ?

Wellsun Medicity | Best Cardiac Hospital in Lucknow

Many people use the terms heart attack and cardiac arrest interchangeably. But medically, they are two different conditions—and both require urgent attention.

In this blog, we will explain Difference between Cardiac Arrest and a Heart Attack:

What is a Heart Attack?

A heart attack happens when the blood flow to the heart muscle is blocked. This blockage usually occurs due to plaque buildup (cholesterol) in the coronary arteries.

When the heart muscle does not receive enough oxygen-rich blood, it starts getting damaged.

Common Causes of Heart Attack

·         High cholesterol

·         High blood pressure

·         Diabetes

·         Smoking

·         Obesity

·         Stress

·         Lack of physical activity

Symptoms of a Heart Attack

·         Chest pain, tightness, or pressure

·         Pain spreading to the left arm, shoulder, jaw, or back

·         Shortness of breath

·         Sweating

·         Nausea or vomiting

·         Dizziness or weakness

    📌 Important Note:

During a heart attack, the person is often conscious and breathing, though in severe cases they may collapse.

What is Cardiac Arrest?

A cardiac arrest occurs when the heart suddenly stops beating. This happens due to an electrical malfunction in the heart that causes an abnormal rhythm (arrhythmia).

When the heart stops, blood stops flowing to the brain and body, and the person can lose consciousness within seconds.

Common Causes of Cardiac Arrest

Abnormal heart rhythm (ventricular fibrillation)

Severe heart attack

Heart failure

Cardiomyopathy

Electric shock

Drowning

Severe electrolyte imbalance

Symptoms of Cardiac Arrest

Sudden collapse

Unconsciousness

No pulse

No breathing (or gasping)

🚨 Cardiac arrest is immediately life-threatening.

How to Identify the Difference Quickly

If the person is awake and complaining of chest pain → It may be a Heart Attack.

If the person collapses suddenly and is not breathing → It is likely Cardiac Arrest.

Can a Heart Attack Cause Cardiac Arrest?

Yes. A heart attack can trigger dangerous heart rhythms, leading to cardiac arrest, especially if treatment is delayed.

That’s why chest pain should never be ignored.

What to Do in an Emergency

✅  If You Suspect a Heart Attack

Keep the person calm and seated

Call an ambulance immediately

Loosen tight clothing

Conclusion

A heart attack is caused by a blockage in blood flow to the heart, while cardiac arrest is when the heart suddenly stops beating due to an electrical failure. Both are serious, but cardiac arrest is instantly life-threatening and requires CPR immediately.

If you notice warning signs, do not wait—seek emergency care right away.

Cardiac arrest and heart attack are two distinct medical conditions that are often confused with each other, but they have different meanings and consequences.

Cardiac Arrest: Cardiac arrest occurs when the heart suddenly stops beating or beats irregularly, resulting in a lack of blood flow to the brain and other vital organs.

This can happen due to various reasons, such as:

·         Electrical problems in the heart

·         Abnormal heart rhythms

·         Heart failure

·         Cardiac tamponade

·         Medication overdose

Cardiac arrest is a medical emergency that requires immediate CPR (cardiopulmonary resuscitation) and defibrillation (using an Automated External Defibrillator (AED) or manual defibrillator) to restore a normal heartbeat

Heart Attack:

A heart attack occurs when the blood flow to the heart is blocked, causing damage or death to the heart muscle.

This blockage is usually caused by:

Coronary artery disease (plaque buildup in the coronary arteries)

Blood clots

Abnormal blood vessels

Heart attacks can cause chest pain or discomfort, shortness of breath, and other symptoms, but they do not necessarily result in cardiac arrest.

 Know come to key point Difference between Cardiac Arrest and a Heart Attack.

Cause: Cardiac arrest is often caused by electrical problems or other factors that affect the heart's ability to pump blood, while a heart attack is caused by a blockage in the coronary arteries.

Symptoms: Cardiac arrest typically presents with no signs of consciousness, while a heart attack often has symptoms like chest pain or discomfort, shortness of breath, and nausea.

Treatment: Cardiac arrest requires immediate CPR and defibrillation, while a heart attack typically requires medical attention to restore blood flow to the affected area.

Outcome: Cardiac arrest can lead to brain damage or death if not treated promptly and effectively, while a heart attack can cause damage to the heart muscle, but prompt medical treatment can help minimize this damage.

Wellsun Medicity Expert Suggested:

Cardiac arrest is a sudden stop in the heart's ability to pump blood, requiring immediate CPR and defibrillation.

A heart attack is a blockage in the coronary arteries that reduces blood flow to the heart muscle, requiring medical attention to restore blood flow.

Cardiac Arrest Symptoms You Should Never Ignore – Wellsun Medicity

 What Is Cardiac Arrest?

Cardiac arrest is a sudden condition where the heart unexpectedly stops beating. When this happens, blood flow to the brain, lungs, and other vital organs stops immediately. Without quick treatment, especially CPR and defibrillation, cardiac arrest can be fatal within minutes. It often occurs without warning, making early awareness extremely important. 

Difference Between Cardiac Arrest and Heart Attack

·         Many people confuse the two, but they are different:

·         Heart Attack: Blood flow to the heart is blocked, but the heart usually continues to beat.

·         Cardiac Arrest: The heart stops beating suddenly due to electrical malfunction.

·         A heart attack can sometimes lead to cardiac arrest, which is why recognizing symptoms matters.

Major Symptoms of Cardiac Arrest You Should Never Ignore

 

1. Sudden Collapse

The person may fall to the ground instantly and become unresponsive. This is often the first and most obvious sign.

2. No Pulse or Very Weak Pulse

When the heart stops, the pulse disappears completely or becomes extremely faint. Quick checking of the pulse is crucial.

3. No Breathing or Abnormal Breathing

Breathing may stop or become irregular (gasping). This is called agonal breathing and should be treated as a sign of cardiac arrest.

4. Loss of Consciousness

The person becomes unconscious and does not respond when called, shaken, or stimulated. 

5. Chest Discomfort (Before Collapse)

Some people may experience chest pain, tightness, or pressure a few moments before arrest happens.

6. Dizziness or Sudden Fainting

A sudden drop in blood flow can cause the person to feel light-headed and faint.

7. Extreme Fatigue or Weakness

Sometimes the body gives a brief warning through unusual tiredness or weakness.

Common Causes of Cardiac Arrest

·         Several medical conditions can trigger sudden cardiac arrest:

·         Severe heart rhythm problems (arrhythmias)

·         Coronary artery disease

·         Heart attack complications

·         Cardiomyopathy (weak heart muscles)

·         Congenital heart defects

·         Severe electrolyte imbalances

·         Electrical shock or trauma

·         Respiratory failure

·         Drug overdose

Understanding these causes helps in prevention and early medical care.

Who Is at Higher Risk? 

People with the following conditions are more likely to experience cardiac arrest:

Previous heart attack

Family history of sudden cardiac death 

High blood pressure

Diabetes 

Smoking

Obesity

High cholesterol

Sedentary lifestyle

Chronic kidney disease

What To Do in Case of Suspected Cardiac Arrest

Quick action can save a life. Follow these steps immediately: 

1. Call Emergency Services

Dial the local emergency number for an ambulance without delay.

2. Start CPR Immediately

Push hard and fast in the center of the chest (100–120 compressions per minute).

This keeps oxygen flowing to vital organs.

3. Use an AED if Available

An Automated External Defibrillator (AED) can shock the heart back into rhythm. Many public places now have AED machines.

4. Continue CPR Until Help Arrives

Do not stop CPR unless the person regains consciousness or medical support arrives.

How to Reduce the Risk of Cardiac Arrest

You can lower the risk with healthy lifestyle habits:

Control blood pressure, diabetes, and cholesterol

Quit smoking

Exercise regularly

Maintain healthy weight

Eat a balanced diet

Manage stress

Go for regular heart checkups

Early diagnosis and preventive care can reduce life-threatening emergencies.

Conclusion

Cardiac arrest can strike without warning, but recognizing symptoms early and acting
