The terms "cardiac arrest" and "heart attack" are often used interchangeably, but they are not the same thing.
A cardiac arrest is when the heart stops working abruptly.
A cardiac arrest is an electrical conduction problem. The heart's electrical system stops working as it should and can either go into an ineffective rhythm (the heart is quivering instead of pumping effectively), or the electrical impulses may stop entirely.
It can occur in an otherwise healthy person, or you may have noticed warning signs.
In a heart attack, a blockage in the coronary arteries (the arteries that supply blood to the heart) prevents oxygen from reaching the heart muscle, leading to muscle death if not treated.
The heart muscle begins to die without oxygen, but the heart has not quit working.
A heart attack is a circulation problem.
A heart attack can lead to a cardiac arrest, but they are not the same thing.
My first cardiac arrest post covered the causes and risk factors of cardiac arrest.
Read this post covered triggers, signs and symptoms, and what to do if you witness a cardiac arrest.
This post will cover cardiac arrest treatments and prevention
If you survive a heart attack outside of the hospital, run to determine what caused your cardiac arrest. Your doctor will admit you to the hospital, run tests to determine the cause of your cardiac arrest, and treat you based on the test results. This may include oxygen, an angioplasty, heart surgery, or an implanted defibrillator devise (similar to a pacemaker) to prevent another cardiac arrest.
Coronary artery disease is the most common cause of cardiac arrest.
Decreasing your risk for coronary artery disease will lessen your chances of cardiac arrest.
Witnessing a cardiac arrest can be a frightening thing; arming yourself with the knowledge and skills to recognize and respond to this medical emergency.
Learn the signs and symptoms of cardiac arrest.
Take a CPR class.
Take note of the AEDs around you, just in case.
Always call 9-1-1 if you witness a collapse, especially if you suspect cardiac arrest.
