The term has been used to describe a diagnosis rather than a symptomology.
Welcome to my tweetorial on a background to “angina pectoris”!
#tweetorials #meded 1/14
Descriptions date back as far as 400BC when Hippocrates observed that some people experienced chest pain precipitated by cold winds.
“Angina pectoris” was first coined by William Heberden in 1768 in his seminal paper “Some account of a Disorder of the Breast”

Heberden’s description has a poetry to it.
In response to his paper he was contacted by a physician who was experiencing angina. The physician requested he perform an autopsy on him to understand it better.

At the time there was no real appreciation for the link between angina and coronary artery disease- so the coronary arteries weren’t examined! 5
John Hunter described emotion as a precipitant for angina. Later he proved this after collapsing and dying after a dispute with a colleague. 6
Near the end of the 19th century, cardiovascular physiologists noted that occlusion of a coronary artery in the dog caused “quivering” of the ventricle which was rapidly fatal.

Selective coronary angiography was developed in 1958 by Sones, Judkins and Amplatz as a method for identifying coronary stenosis.

This suggested that epicardial stenosis is only part of the disease spectrum.

“microvascular angina” describes this response of the intramural pre arteriolar coronaries.

The coronary circulation can be subdivided into different sub compartments based on structure and function.
