Heart Attack vs. Cardiac Arrest: Why the Difference Matters
Beaumont – October 28, 2026 -- A heart attack and a cardiac arrest are not the same emergency, and knowing which one is happening determines what help a person needs. A new HelloNation article, featuring Justin Doss, COO of Community Hospital Corporation of Baptist Hospitals of Southeast Texas in Beaumont, explains the distinction.
A heart attack is a blocked artery; cardiac arrest is an electrical failure
A heart attack happens when a blocked artery cuts off blood flow to the heart. Oxygen to the heart muscle drops, and damage can build over time. The heart usually keeps beating, and warning signs such as chest pain, shortness of breath, or fatigue tend to develop more gradually.
Cardiac arrest is a sudden loss of heart rhythm that makes the heart stop beating. It often comes without warning, and a person can collapse instantly. Without immediate CPR or defibrillation, it can be fatal within minutes.
