Angina can occur when the heart is not getting enough oxygen. This
is usually because the blood supply to the heart is blocked or because the heart is being
overworked and therefore needs more oxygen than usual. The heart can usually function
normally at rest but not when physically exerted.

If you have stable angina,
you should be able to predict what sort of activity will bring on an attack. Another type,
unstable angina, is a more acute condition; it occurs unpredictably, even during rest, and
should be interpreted as a warning sign of more serious heart trouble.
Alone, angina causes no
permanent damage because the heart is only temporarily deprived of oxygen. But if your
angina worsens, you should know that you are at a greater risk of heart attack. Be
especially concerned if you develop unstable angina, and consult a doctor.
The main underlying cause of
angina is coronary artery disease which describes the disease which the arteries become
blocked by fatty deposits and blood is prevented from flowing through them. Angina can
also result from other diseases that put exertion upon the heart unnecessarily, such as
anaemia, aortic valve disease (see heart disease), heart arrhythmias, and hyperthyroidism
(see thyroid problems).
Stable angina is sometimes
called "exertional" angina because it is triggered by activities that make the
heart beat rapidly such as physical activity, such as heavy lifting, sexual activity to
eating a large meal.
Other triggers are emotional
excitement cold weather, both of which stimulate the heart.
Certain risk factors for
heart disease and coronary artery disease make the development of angina more likely.
