The symptom of paroxysmal pain consequent to MYOCARDIAL ISCHEMIA usually of distinctive character, location and radiation. It is thought to be provoked by a transient stressful situation during which the oxygen requirements of the MYOCARDIUM exceed that supplied by the CORONARY CIRCULATION.

A disease, the precise pathology of which is not known. The principal symptoms are, violent pain about the sternum, extending towards the arms, anxiety, dyspnoea, and sense of suffocation. It is an affection of great danger, and is often connected with ossification, or other morbid condition of the heart. It appears to be neuropathic, and has been termed Neuralgia of the Heart. Some, however, employ this last term for an acutely painful intermittent affection of the heart, which seems to differ from angina pectoris more in regard to the small number of parts which are drawn into morbid consent with the affected cardiac nerves, than in regard either to its nature or appropriate treatment. The most powerful stimulating and narcotic antispasmodics are required during the paroxysm.
