What is a heart attack?

The most common cause of a heart attack is coronary heart disease.
A heart attack occurs when a coronary artery, which supplies blood to your heart, becomes blocked.
The most common sign of a heart attack is chest discomfort or pain, which can spread to your arms, neck, jaw or back.
Chest discomfort or pain can last for several minutes or come and go.
A heart attack requires emergency treatment to restore blood flow to your heart.
Always call Triple Zero (000) immediately if you think you or someone else may be having a heart attack.

I appreciate all the explanations in the video but would like it a lot more if there was no background music. It interferes with the voice and makes it difficult to understand the explanations.
