Treatment can help stop angina attacks and reduce the risk of further problems like heart attacks.
Most people with angina need to take several medicines. Surgery may be recommended if medicines do not help.
It's also important to make healthy lifestyle changes.
If you have stable angina (the most common type), you'll be given medicine to take when you have an angina attack.
This is called glyceryl trinitrate, or GTN. It comes as a mouth spray or tablets that dissolve under your tongue.
If you have an angina attack:
You can also use GTN to avoid an attack before doing something like exercise. You may have a headache, flushing or dizziness soon after using it.
GTN tablets usually expire about 8 weeks after the packet is opened, at which point you'll need to replace them. GTN spray lasts much longer, so may be more convenient.
To help avoid more attacks, you'll also need to take at least 1 other medicine every day for the rest of your life. Some people need to take 2 or more medicines.

If you cannot have either of these medicines, you may be given another medicine such as ivabradine, nicorandil or ranolazine.

Surgery may be recommended if medicines are not helping control your angina.
The 2 main types of surgery for angina are:
Both of these operations are similarly effective. The best one for you depends on your circumstances. If surgery is recommended, talk to your doctor or surgeon about your options.
You'll probably need to continue taking some medicines after surgery.
If you have unstable angina (where symptoms develop unpredictably), you'll need medicines to prevent blood clots and reduce your risk of having a heart attack or stroke.
You may be given:
Surgery (either CABG or PCI) may be recommended if you have a high risk of having another angina attack, or you're at a high risk of having a heart attack or stroke.
