Cardiac Arrest vs. Heart Attack: Understanding the Differences and Similarities
Heart-related emergencies are often a cause of concern, and two terms that are sometimes used interchangeably are "cardiac arrest" and "heart attack." However, it is crucial to recognize that these are distinct medical conditions with different causes, symptoms, and treatments. Understanding the differences between cardiac arrest and heart attack can be life-saving, as prompt action is vital in both situations.
Cardiac Arrest: Cardiac arrest is a sudden and life-threatening condition where the heart stops beating, leading to a cessation of blood flow throughout the body. It is an electrical malfunction in the heart, causing arrhythmias like ventricular fibrillation or ventricular tachycardia. During cardiac arrest, the person loses consciousness, stops breathing, and has no pulse. It is a medical emergency requiring immediate intervention.
Causes: Cardiac arrest can be triggered by various factors, including heart conditions, electrolyte imbalances, drug overdoses, trauma, or certain medical conditions like congenital heart defects.
Treatment: Immediate action is essential. Bystanders should call emergency services and start cardiopulmonary resuscitation (CPR) to manually circulate blood and oxygen until professional help arrives. Defibrillation with an Automated External Defibrillator (AED) is also crucial to attempt restoring the heart's normal rhythm.
Heart Attack: A heart attack, also known as a myocardial infarction, occurs when there is a blockage in one or more coronary arteries, restricting blood flow to a part of the heart muscle. This blockage is usually caused by a buildup of cholesterol plaque, leading to reduced oxygen supply to the heart muscle.
Symptoms: Heart attack symptoms can vary but often include chest pain or discomfort, shortness of breath, lightheadedness, nausea, and pain radiating to the arm, back, neck, or jaw.
Treatment: Seeking immediate medical attention is crucial during a heart attack. Timely treatment aims to restore blood flow to the affected part of the heart through medications or medical procedures like angioplasty and stent placement.
Key Differences:

Key Differences:
Cause: Cardiac arrest is an electrical problem in the heart's rhythm, while a heart attack is caused by a blocked artery.
Circulation: In cardiac arrest, the heart stops beating, leading to a lack of blood flow throughout the body. In a heart attack, blood flow is restricted to a specific part of the heart.
Consciousness: During cardiac arrest, the person loses consciousness immediately, while a heart attack patient may remain conscious.
