What are 3 differences between heart attacks and cardiac arrest?

People are often confused between a heart attack and a cardiac arrest. Both are serious medical emergencies.

In today's times, the cases of heart attack and cardiac arrest have increased in younger age groups, and there is a lot of confusion around this.

This story has been brought to light after BJP leader Shahnawaz Hussain suffered a heart attack recently.

Let us understand three major differences between the two.

A heart attack is occured when one of the coronary arteries (blood vessel) becomes blocked. It is caused due to lack of oxygen supply or death of heart cells.

A cardiac arrest is occured when a person's heart stop pumping blood and oxygen in the body.

A heart attack can cause cardiac arrest, but not all cardiac arrests are caused by heart attacks.

Warning signs of cardiac arrest which are not signs of a heart attack include sudden loss of consciousness, no breathing and lack of pulse.

Warning signs of heart attack, which are not present in case of cardiac arrest include massive pain, faint, neck discomfort.
