Heart Attack and Cardiac Arrest


As a cardiology expert at Medsarc Super Specialty Clinics, I am often asked about the difference between a heart attack and cardiac arrest. These terms are frequently used interchangeably, but they represent distinct medical emergencies with different causes, symptoms, and treatments. Understanding these differences is crucial for effective response and prevention, and for maintaining optimal heart health. Let’s delve into the specifics of each condition and explore practical tips to keep your heart healthy.

Heart Attack: A Blockage in Blood Flow

A heart attack, or myocardial infarction, occurs when the blood flow to a part of the heart is blocked for an extended period. This blockage is often due to a buildup of fat, cholesterol, and other substances, which form a plaque in the coronary arteries. When the plaque ruptures, a blood clot forms and obstructs the flow of blood. This lack of oxygen-rich blood can damage or destroy part of the heart muscle.

Symptoms of a Heart Attack:

  • Chest pain or discomfort (angina) that may spread to the shoulders, arms, back, neck, or jaw.
  • Shortness of breath.
  • Nausea or vomiting.
  • Lightheadedness or sudden dizziness.
  • Cold sweat.

Cardiac Arrest: A Sudden Electrical Malfunction

Cardiac arrest, on the other hand, occurs when the heart’s electrical system malfunctions, causing an irregular heartbeat (arrhythmia). When the heart stops beating suddenly, it cannot pump blood to the brain, lungs, and other organs. Cardiac arrest is a critical condition that requires immediate medical attention, as it can lead to death within minutes without intervention.

Symptoms of Cardiac Arrest:

  • Sudden collapse.
  • No pulse.
  • No breathing.
  • Loss of consciousness.

It’s important to note that a heart attack can sometimes trigger a cardiac arrest, but the reverse is not necessarily true.

Immediate Response and Treatment

For a Heart Attack:

  • Call emergency services immediately.
  • Chew and swallow an aspirin, unless you are allergic or have been told by your doctor not to take it.
  • Use nitroglycerin if prescribed.
  • Stay calm and rest while waiting for emergency responders.

For Cardiac Arrest:

  • Call emergency services immediately.
  • Begin CPR (cardiopulmonary resuscitation) to maintain blood flow to the brain and other vital organs.
  • Use an Automated External Defibrillator (AED) if available, following the device’s instructions.
