Angina

The main symptom of angina is sudden pain in your chest, neck, shoulders, jaw or arms.

The pain may:

• feel like tightness, squeezing or pressure, or like a dull ache
• make you feel sick, breathless, dizzy or sweaty

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.

If a GP thinks you may have angina, you'll be referred to a heart specialist (cardiologist).

You may have tests including:

• blood tests
• an electrocardiogram (ECG) to check the electrical activity of your heart
• checking the level of oxygen in your blood
• scans, such as an angiogram, MRI scan or CT scan

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:

• are a man aged 45 or over, or a woman aged 55 or over
• smoke
• drink more than 14 units of alcohol a week
• are living with obesity or overweight
• have high blood pressure or high cholesterol
• have had heart problems before, like a heart attack or heart rhythm problem (arrhythmia)
• have close relatives who have heart problems
• have another condition, such as diabetes, arthritis or kidney disease

If you have angina, you may be given medicine to:

• treat an angina attack if you have one (glyceryl trinitrate)
• lower your chances of having an angina attack, such as beta blockers
• reduce your risk of having a stroke or heart attack, such as low-dose aspirin or statins

Sometimes you may be recommended to have surgery to increase the blood flow to your heart (coronary angioplasty or a coronary artery bypass).

If you have angina, there are things you can do to help symptoms or reduce the chance of attacks.

• avoid things that trigger your angina attacks as much as possible, like stress, cold temperatures or eating large meals

• always have your angina medicine with you – use it as you have been told by your doctor

• try to quit smoking, if you smoke

• try to keep to a healthy weight

• eat a balanced diet

• have the most active lifestyle your symptoms will allow

• try to cut down on alcohol if you drink more than 14 units a week

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.

The main symptom of angina is a feeling of pain, tightness or squeezing in your chest, neck or jaw. It's often triggered by exercise or stress.

Angina is caused by the heart not getting enough blood, usually due to coronary heart disease. In some people, the blood vessels do not work properly.

Angina may be treated with medicine to ease the symptoms and reduce the risk of having a stroke or heart attack.

Having a healthy lifestyle and avoiding triggers such as stress can help prevent angina attacks.

If angina is treated and you make healthy lifestyle changes, symptoms can get better over time and should not stop most everyday activities.
