Understanding the Difference Between a Heart Attack and Cardiac Arrest
What is a Heart Attack?
A heart attack occurs when blood flow to the coronary artery is blocked or partially obstructed, preventing the heart muscle from receiving the necessary blood supply. Blood carries oxygen essential for the heart muscle’s function, making prompt restoration of blood flow critical. This blockage often arises when plaque breaks away, leading to the formation of a thrombus that can partially or completely obstruct the artery. Essentially, a heart attack represents a problem with circulation.
What is Cardiac Arrest?
In contrast, cardiac arrest is triggered by an abnormal heart rhythm, known as arrhythmia. During this event, the heart fails to receive proper electrical impulses, disrupting its ability to beat effectively. Individuals experiencing cardiac arrest require immediate intervention, typically through cardiopulmonary resuscitation (CPR) and, in some cases, defibrillation. Defibrillation aims to reset the heart’s rhythm by delivering a controlled shock.
Link Between Heart Attacks and Cardiac Arrest
It is important to emphasize that while heart attacks and cardiac arrests are distinct conditions, a heart attack can potentially lead to cardiac arrest. However, the majority of heart attacks do not result in cardiac arrest.
