Overview
This video explains the differences between cardiac arrest, heart attack, and heart failure, detailing their causes, mechanisms, and consequences. It aims to clarify these distinct medical emergencies to improve understanding.
Key takeaways
Cardiac Arrest: Occurs when the heart's pumping chambers (ventricles) stop pumping blood effectively, either by ceasing altogether (asystole) or quivering uncontrollably (ventricular fibrillation, often preceded by ventricular tachycardia). This is a common cause of sudden death if not resolved quickly.
Heart Attack: Typically caused by a blockage in the coronary arteries due to a buildup of atherosclerotic plaque. When a plaque ruptures, a blood clot forms, obstructing blood flow and potentially causing heart muscle death.
Heart Failure: Happens when either the left or right side of the heart doesn't function correctly, leading to blood backing up. Left-sided failure can cause fluid in the lungs (shortness of breath) and reduced blood flow to the body (fatigue). Right-sided failure can cause swelling in the legs and feet. Heart failure can also lead to blood clots and dangerous heart rhythms.
