What is the difference between cardiac arrest and a heart attack?

Cardiac Arrest: Cardiac arrest is a sudden and unexpected loss of heart function. It occurs when the heart’s electrical system malfunctions, causing the heart to stop pumping blood to the body. During cardiac arrest, the person loses consciousness, stops breathing, and their pulse becomes absent or extremely weak.

Cardiac arrest is a medical emergency that requires immediate intervention. Without prompt treatment, it can quickly lead to death. Cardiopulmonary resuscitation (CPR) and the use of an automated external defibrillator (AED) are crucial in restoring the heart’s normal rhythm and providing a chance for survival.

Heart Attack (Myocardial Infarction): A heart attack, also known as a myocardial infarction (MI), occurs when there is a blockage in one or more of the coronary arteries that supply blood to the heart muscle. The blockage is usually caused by a blood clot that forms on a ruptured plaque within the artery.

During a heart attack, the blood flow to a section of the heart muscle is significantly reduced or completely cut off. This lack of blood flow can cause damage or death to the affected part of the heart muscle. Symptoms of a heart attack may include chest pain or discomfort, shortness of breath, nausea, lightheadedness, and pain radiating to the arm, jaw, or back.

Unlike cardiac arrest, a heart attack does not always lead to cardiac arrest. However, if a heart attack is severe and not promptly treated, it can potentially trigger a cardiac arrest event.

It’s important to note that while cardiac arrest and heart attack are related, they are distinct medical conditions with different causes and treatment approaches. Prompt recognition and appropriate response are crucial in both cases to improve the chances of survival and minimize potential complications. If someone experiences symptoms of a heart attack or witnesses a cardiac arrest, it is essential to call emergency services immediately.
