Symptoms
You experience a pain in the centre of the chest, which may also travel into the neck, jaw, and arms (especially the left). Angina is usually described as a crushing or heavy or gripping pain. It mostly follows exercise, but may also be triggered by emotion, digesting a heavy meal, or going out in a cold wind. Sometimes you may also feel breathless.
Causes
Angina is rather similar to cramp in a muscle during vigorous exercise. It is caused by the muscles of the heart not receiving enough oxygen (via the blood) for the work they are performing. This is because the blood vessels which supply the heart muscles with oxygen have become narrowed. The main cause of narrowing of the blood vessels is age, but this is accelerated by cigarette smoking. To a lesser extent people with a high cholesterol level, people who are obese (overweight), and diabetics are also more at risk.
Diagnosis
Diagnosis of angina is largely from the history. That is, there has been pain, usually brought on by exertion, which is situated as indicated above, usually goes off within a few minutes when you stop what you are doing, and is relieved by sucking a GTN (glyceryl trinitrate) tablet under the tongue.
Your doctor may also want you to undertake an electrocardiogram (ECG - a tracing which shows the electrical activity of the heart) and an exercise ECG (this involves walking on a treadmill while attached to an ECG). He is also likely to check your weight, blood pressure, various blood tests including blood sugar and cholesterol, and to discuss your smoking and drinking habits. All of these may be normal even though you are suffering from angina.
Treatment
If you think you have angina you should consult your doctor. He may well prescribe some tablets to suck under your tongue (these are however cheaper to buy over the counter), or the same medication as a spray (this has a longer shelf life than the tablets which only last two months after opening). They work by opening the blood vessels, and as a result may give a side effect of throbbing headache. If this happens you can spit out the tablet as it will already be working on the blood vessels. Should you suffer from this side effect, persevere as it usually wears off after the first two or three tablets. Norvasc is an effective medicine to treat angina.
Angina usually lasts no longer than ten minutes, and if you get it you should stop what you are doing and take one of the tablets or a puff of the spray under your tongue. If an activity always seems to bring it on then it is wise to take the treatment before you start. If you are suffering frequently you should consult your doctor as he will probably wish to consider preventative treatment which will involve regular tablets.
If your symptoms are not controlled by drugs and also if the tests suggest it, your doctor may refer you to a heart specialist (cardiologist) for consideration of further treatment. It is likely that at this stage you would have a test to show up the blood vessels which supply oxygen to the heart muscle (coronary angiography).
Further treatment is not necessary except in quite advanced cases and involves either using a tube to enlarge the blood vessels where they are narrowed (angioplasty) or bypassing the blood vessels with alternative vessels (coronary artery bypass grafts - CABG).
