Coronary circulation is the “movement of blood through the vessels of the heart.”[1]


The Persian polymath Abu Ali al-Husayn ibn Abdullah ibn al-Hasan ibn Ali ibn Sina discovered[2] coronary circulation around 1025 after stating in “The Canon of Medicine” that “There are two branches that originate at the base of the aorta, the larger one goes round the surface of the heart and distributes in the parts of the heart, the smaller branch also rounds the heart and distributes around the surface of the right cavity (ventricle).”


Here is a portrait[3] of Ibn Sina:
