Angina pectoris

Chest pain that is typically severe and crushing with a feeling just behind the breastbone (the sternum) of pressure and suffocation, due to an inadequate supply of oxygen to the heart muscle.

pain in the centre of the chest, which is induced by exercise and relieved by rest and may spread to the jaws and arms. Angina pectoris occurs when the demand for blood by the heart exceeds the supply of the coronary arteries and it usually results from coronary artery atheroma. It may be prevented or relieved by such drugs as glyceryl trinitrate and propranolol. If drug treatment proves ineffective, coronary angioplasty or coronary bypass graft may be required, the former being less invasive than the latter.

It is subdivided into stable and unstable a. pectoris. Called also a. cordis, angor pectoris, Heberden disease, and Rougnon-Heberden disease.
