Caleb Hillier Parry (1755 – 1822) was an English physician.
Parry is best remembered for his accurate description of the pathophysiology of ischaemic heart disease
He was the first to establish a relationship between angina and coronary heart disease, and that the functional efficiency of the coronary arteries was more indicative than their structural integrity
Described the concept that ischaemic heart disease resulted from energy demands of the myocardium, which the vascular system was unable to supply
1825: He was the first to write accounts of the condition now known as progressive hemifacial atrophy (Parry-Romberg syndrome – 1846); congenital idiopathic dilatation of the colon (Hirschprungs disease – 1886) and expopthalmic goitre (Graves disease – 1935)
The most dangerous state incidental to the human mind is a calm acquiescence in the accuracy and extent of its own attainments – Parry CH

Parry’s description of ‘Hirschsprung’s disease‘ was in a male adult with chronic digestive disturbances. Autopsy revealed an enormously distended colon with no evidence of obstruction in the alimentary canal [Parry CH, 1825 pp380-386].
