“Four of these hearts are very well preserved. It is very rare in archaeology to work on organic materials. The prospects are very exciting.”

One heart appeared healthy, with no evidence of disease. Three others showed indications of disease, atherosclerosis, with plaque in the coronary arteries. The fifth was poorly preserved.
