Is Cardiac Arrest More Dangerous Than a Heart Attack?

Yes, cardiac arrest is generally more dangerous because it happens suddenly and can cause death within minutes if not treated immediately. Many people confuse heart attack and cardiac arrest, but they are different conditions.

What is the Difference?

• Heart Attack:

  • Caused by blockage in the arteries supplying blood to the heart muscle.

  • Develops gradually; symptoms like chest pain and shortness of breath often appear before the attack.

  • Treatment involves medicines or surgery and usually there is time to get help.

• Cardiac Arrest:

  • Caused by a malfunction in the heart’s electrical system, leading to sudden stopping of the heartbeat.

  • Blood circulation stops instantly, so the brain and organs get no oxygen.

  • Often occurs without warning, and the person loses consciousness immediately.

  • Requires immediate CPR and defibrillation to save life.

Why is Cardiac Arrest More Dangerous?

Because the heart stops pumping suddenly, the body’s organs get no oxygen. Death can occur within 2 to 4 minutes if emergency help is not given. In contrast, a heart attack usually progresses slower, giving some time for treatment.

Symptoms of Cardiac Arrest

• Sudden loss of consciousness

• Very slow or stopped breathing

• No pulse or heartbeat

• In some cases, severe chest pain or anxiety shortly before arrest

• Eyes open but unresponsive

What to Do If Someone Has Cardiac Arrest?

• Immediately start CPR (Cardiopulmonary Resuscitation)

• Use an Automated External Defibrillator (AED) if available

• Call emergency services (like 108 in India) without delay

• Remember, every minute without CPR or defibrillation lowers the chance of survival

Learning to recognize cardiac arrest and perform first aid like CPR can save lives.
