Many people confuse heart attack vs cardiac arrest, but they are not the same. One is a circulation problem. The other is an electrical problem. Both are emergencies, but the response is different. This blog breaks down what a heart attack is, what cardiac arrest is, and how to act when every second matters.
What is a Heart Attack and What Causes It?
A heart attack happens when blood flow to part of the heart is blocked. The heart muscle doesn’t get enough oxygen. If the blockage isn’t cleared, the muscle starts to die.
Common causes include:
- A buildup of plaque in the arteries
- A blood clot that blocks flow
- Severe narrowing of coronary arteries
Knowing what is a heart attack helps you understand the urgency. It’s a medical emergency, but the person is often still awake and talking.
What is Cardiac Arrest and How is It Different?
Cardiac arrest is when the heart suddenly stops beating. Blood stops flowing to the brain and other vital organs. Without treatment, the person will die in minutes.
It’s different from a heart attack in key ways:
- It happens without warning
- The person collapses and becomes unresponsive
- Breathing stops or becomes abnormal
- It requires CPR and defibrillation immediately
Understanding what is cardiac arrest means knowing it’s a sudden loss of function. It may be caused by a heart attack, but also by trauma, electrical shock, or inherited heart problems.
Warning Signs of Heart Attack to Watch For
Heart attack symptoms may come on slowly or suddenly. Learning the warning signs of heart attack can help you act before it becomes life-threatening.
Watch for these signs:
- Chest pain or pressure, often lasting more than a few minutes
- Pain in the arm, neck, jaw, or back
- Shortness of breath
- Nausea or lightheadedness
- Cold sweat
Symptoms can vary. Women may have less obvious signs, like fatigue or indigestion. If you suspect a heart attack, call 911 immediately. Do not wait.
How to Respond to Cardiac Arrest
If someone collapses and isn’t breathing normally, assume cardiac arrest. Every second counts. Knowing how to respond to cardiac arrest can save a life.
Steps to take:
- Call 911 immediately.
Tell them someone is unresponsive and not breathing. - Start CPR.
Push hard and fast in the center of the chest—about 100 to 120 compressions per minute. - Use an AED if available.
Turn it on and follow the prompts. The shock may restart the heart. - Do not stop until help arrives.
Keep going with CPR or let another trained person take over.
