Q: What’s the difference between a heart attack and cardiac arrest?
A heart attack (myocardial infarction, MI) occurs when a blood clot blocks the flow of blood through one of coronary arteries, a blood vessel supplying blood to a part of the heart muscle. Interrupted blood flow to your heart can damage or destroy a part of the heart muscle.
Cardiac arrest is the sudden, unexpected loss of heart function, breathing and consciousness. Sudden cardiac arrest usually results from an electrical disturbance in your heart that disrupts its pumping action and causes blood to stop flowing to the rest of your body. Cardiac arrest almost always occurs in the context of other underlying heart problems, particularly coronary artery disease resulting in myocardial infarction or primary electrical problem resulting in abnormal rhythm called ventricular fibrillation.
