These symptoms may be called an angina attack, episode or pain.
They are often brought on by exercise, stress, emotion or cold temperatures – although sometimes there's no obvious trigger.
Angina attacks usually last less than 10 minutes and should stop after resting for a few minutes or taking your angina medicine.

Angina happens when the heart does not get enough blood.
This is usually due to coronary heart disease, where the blood vessels supplying blood to the heart become narrowed or blocked by fatty deposits.
But it can also be caused by the blood vessels in your heart tightening when they should not (vasospastic angina or microvascular angina).
You're more likely to get angina if you:

Having angina means you're at higher risk of having a heart attack or stroke. It's important to treat it and make healthy lifestyle changes to reduce this risk.
With treatment, the symptoms should improve over time and may eventually stop.
If your symptoms are well controlled, angina will not usually have a big impact on your life. You'll usually be able to continue with most things, including exercise and sex.
But angina may affect your work if you have a job that involves a lot of physical activity, or if you drive buses, coaches or lorries.
Your doctor will talk to you about any changes you may need to make, and whether you need to inform the DVLA about your condition.
It's also best to speak to your doctor before you take up a new activity or if you're worried about exercising.
You may also need to think about practical things like always carrying your angina medicine, having spare medicine available and making sure you have enough with you when travelling.
