Heart attacks are a very common issue but that should not detract from them being serious medical emergencies.

Heart attacks are more likely to affect men over the age of 45 and women over 55 as well as those with high blood pressure and those who are obese.

However, heart attacks can affect almost anyone with those who have a family history of heart attacks, particularly at risk.

If you suspect you or someone you know is having a heart attack, you should call 999 and ask for an ambulance.

What causes a heart attack?

Heart attacks are usually caused by coronary heart disease (CHD) with this being the leading cause of these attacks, according to the NHS.

This condition sees major blood vessels that supply the heart get clogged with deposits of cholesterol, known as plaque.

This causes a lack of blood going to the heart which can seriously damage the muscle and become life-threatening.
