ABSTRACT
Angina (strangle) pectoris (chest) was first described before it was believed the heart could be responsible for any sort of illness within the body. It is thus a description of clinical symptoms, first described by Heberden in 1768. In its nature it is unchanged today. Angina pectoris refers to pain coming on in the chest, radiating to the arms (usually left) or neck, and associated with exercise or excitement. It is relieved when the stimulus ceases. It is worse in cold or windy weather or after a large meal when the heart’s cardiac output increases.
