Heart attack or cardiac arrest

I will like to know the difference between a Heart Attack and a Cardiac Arrest

A heart attack is when a blocked artery stops blood from reaching a section of the heart. If the blocked artery is not reopened quickly, the part of the heart normally fed by that artery begins to die. The longer a person goes without treatment, the greater the damage.

Symptoms of a heart attack may be immediate and intense or start slowly with mild symptoms. It’s also possible to have mild symptoms or even no symptoms and still have a heart attack. The heart usually doesn’t stop beating during a heart attack.

However, Sudden cardiac arrest happens suddenly and often without warning. It happens when an electrical failure in the heart causes an irregular heartbeat “arrhythmia”. The heart can’t pump blood to the brain, lungs and other organs. This causes a person to lose consciousness and a pulse. The person can die if they don’t receive help within minutes.
