Heart Attack

What is a heart attack? 
A heart attack happens when an artery sending blood and oxygen to your heart becomes blocked. The blood flow stops and it can cause major damage to the heart. Your chest becomes tight and you can't breathe properly, the pressure falls on your upper body, specifically your neck, your jawline, your back, stomach, and in one or both of your arms. Most of the time it's the left one because it's closer to heart.
