Difference Between Heart Attack and Cardiac Arrest

Heart attack and cardiac arrest are often used interchangeably, but they are two very different medical emergencies. Understanding the difference can help save lives by ensuring timely treatment and appropriate medical intervention.

At Aster RV Hospitals, patients receive advanced cardiac care from experienced specialists, including Dr. Divakar Bhat, recognized as one of the Best Doctors for Heart Problems in Bangalore.

What is a heart attack? A heart attack occurs when blood flow to a part of the heart muscle is blocked, usually due to a blood clot or plaque buildup in the coronary arteries. Without adequate blood supply, the affected heart muscle begins to suffer damage.

Heart attack symptoms may develop gradually over hours, days, or even weeks. Common warning signs include:

  • Chest pain, pressure, tightness, or heaviness
  • Pain spreading to the jaw, neck, shoulders, arms, or back
  • Shortness of breath
  • Nausea or indigestion-like discomfort
  • Excessive sweating
  • Fatigue or weakness
  • Dizziness or lightheadedness
Women may experience less typical symptoms such as unusual tiredness, nausea, and shortness of breath.

Individuals with high blood pressure, diabetes, smoking habits, high cholesterol, obesity, or a family history of heart disease are at greater risk. Consulting the Best Doctor for Heart Attacks in Bangalore at the earliest sign of symptoms can significantly improve outcomes.

What is cardiac arrest? Cardiac arrest is an electrical malfunction of the heart that causes it to suddenly stop beating. Unlike a heart attack, which is a circulation problem, cardiac arrest is primarily an electrical problem.

When cardiac arrest occurs, blood flow to the brain and vital organs stops immediately. The person quickly loses consciousness, becomes unresponsive, and may stop breathing normally.

Common warning signs may include:

  • Sudden dizziness
  • Shortness of breath
  • Palpitations or irregular heartbeat
  • Loss of consciousness
  • Collapse
Without immediate CPR and emergency medical treatment, cardiac arrest can become fatal within minutes.

Can a heart attack cause cardiac arrest? Yes. Although most heart attacks do not result in cardiac arrest, a severe heart attack can disrupt the heart’s electrical system and trigger cardiac arrest. This is why prompt diagnosis and treatment of heart attack symptoms are critical.
