Knowing the precise difference between a cardiac arrest and heart attack is important to effectively manage medical emergencies. These two terms are often used interchangeably, hence many people assume that they are synonymous to each other. But Cardiac arrest is actually quite different from a heart attack. These two emergencies have their own characteristics, symptoms, diagnosis and prognosis. According to a report by the Centers of Disease Control and Prevention, a precise diagnosis of the condition can significantly impact patient outcomes.
One crisp difference between cardiac arrest and heart attack is that the heart completely stops functioning during a cardiac arrest. A heart attack is also called Myocardial Infarction and this happens when blood flow to a part of the heart is blocked. In this case tissue damage takes place. So in this blog, we will explore the difference between cardiac arrest and heart attack.
In the table mentioned below, you will find the core points separating a Cardiac Arrest from Heart Attack.
Aspect | Cardiac Arrest | Heart Attack |
Definition | Sudden loss of heart function, often leading to unconsciousness and stoppage of breathing | Blockage in blood flow to the heart, causing damage to heart muscle tissue |
Cause | Irregular heart rhythms (arrhythmias), often stemming from electrical malfunctions | Blockage or narrowing of coronary arteries, typically due to plaque buildup |
Symptoms | Abrupt loss of consciousness, no pulse, no breathing, sometimes preceded by chest pain, shortness of breath and nausea | Chest pain or discomfort, shortness of breath, fatigue, nausea, and lightheadedness |
Treatment | Immediate CPR (Cardiopulmonary Resuscitation) followed by defibrillation, and ACLS (advanced cardiac life support) | Medications (such as aspirin and clot-busters), angioplasty, stent placement, bypass surgery |
Prognosis | Immediate medical attention crucial; survival rates vary depending on response time and underlying cause | Prompt treatment improves outcomes; damage to heart muscle can lead to complications or death if left untreated |

When someone experiences a heart attack, prompt intervention is critical. This minimizes the damage to the heart muscles. It also improves the individual’s chances of survival. Understanding the steps of intervention can empower bystanders and healthcare professionals to a great extent. Below are the steps of a heart attack intervention-
Familiarize yourself with common symptoms of a heart attack, such as chest pain or discomfort, shortness of breath, nausea, lightheadedness, and cold sweats.
Dial emergency services (such as 911) immediately upon suspecting a heart attack to ensure swift medical assistance.
If the person is conscious and not allergic to aspirin, provide them with a chewable aspirin (usually 325 mg) to help reduce blood clot formation.
If prescribed and available, assist the individual in taking any prescribed medications for heart conditions, such as nitroglycerin.
Help the person sit or lie down in a comfortable position, preferably with their knees bent if experiencing chest discomfort.
Keep a close watch on the person’s vital signs, including their pulse and breathing, while waiting for emergency medical services to arrive.
If the person becomes unresponsive and stops breathing normally, be prepared to perform cardiopulmonary resuscitation (CPR) until professional help arrives.
Share any relevant medical history or information about the individual’s condition with emergency responders to aid in their assessment and treatment.

Understanding the difference between a cardiac arrest and heart attack helps make confident and competent decisions in the face of crisis. While both the conditions involve the heart, the core differences lie in the symptoms, diagnosis and treatment. Cardiac arrest refers to the loss of heart function and heart attacks result from blocked blood flow. Even though both the conditions are equally time sensitive, without timely intervention, it can quickly turn fatal. So stay ahead of these emergencies and know the differences between heart attack and cardiac arrest. With proper knowledge on cardiac health, individuals can adapt to these critical emergencies to cultivate a safer and more prepared community.
