Atherosclerosis in Ancient Egypt


Atherosclerosis and vascular calcification are usually regarded as circulatory phenotypes associated with advanced modern lifestyles, it is however evident in the remains of many ancient Egyptians. 

The mummification process was usually done for the more affluent members of society, and a rich legacy of archaeological and literary evidence, as well as the pathology preserved in both skeletal and mummified remains, has enabled disease studies to be undertaken. 

Marc Ruffer described arterial lesions in hundreds of Egyptian mummies in 1911 and Graham Shattock noted atheromatous deposits in the aorta of King Menephtah in 1909; these findings were later confirmed by John Harris and Edward Wente's radiological survey in 1980, which additionally reported vascular calcification (occurs frequently in atherosclerotic lesions) in the mummies of Ramesses II, Ramesses III, Sethos I, Ramesses V, and Ramesses VI.

Egyptologist Gomaa Abdel-maksoud prepares a mummy for a CT scan. The researchers were looking for evidence of arterial disease in the mummies. This mummy, Hatiay, who lived between 1550 and 1295 BC, had extensive vascular disease.

In 2009, computed tomography (CT) was used to assess atherosclerosis in a selection of 22 mummies of Egyptians with high social status. In 16 of these where the hearts or arteries could be identified, nine mummies showed evidence of vascular calcification. However, although arteriosclerosis has been clearly identified in mummies, it seems to have been fairly uncommon in ancient Egypt. This perhaps reflects the life expectancy at the time of between 40 and 50 years, even among the more affluent members of society, but may also result from differences in intakes of foodstuffs between most Egyptians and the affluent elite.

The palaeopathological evidence can now be examined in conjunction with ancient texts to provide further insight into the occurrence of the disease among the ancient Egyptian elite. Interpretation of the hieroglyphs indicates that the diet of the priests and their families consisted mainly of beef, wildfowl, bread, fruit, vegetables, cake, wine, and beer. Many of these food items would obviously have contributed to an intake of saturated fat. Moreover, Egyptian priests consumed little fish, and while oily fish is a major source of omega 3 fatty acids, which are also advocated in cardiovascular disease prevention, it is unlikely that the intake would have achieved anything like that required. 

It is important to point out that there was a marked difference between the mainly vegetarian diet most Egyptians ate and that of royalty and priests and their family members whose daily intake would have included these high levels of saturated fat. Mummification was practised by the elite groups in society, ensuring that their remains have survived to provide clear indications of atherosclerosis; by contrast, there is a lack of evidence that the condition existed among the less well-preserved remains of the lower classes. Since most mummies available for study will inevitably belong to the wealthier members of Egyptian society, most scientific data relate to the health of these people.

Thanks for compiling all of these info. I guess heart diseases have been present amongst human beings since the dawn of time. But was there a specific reason why the Egyptians didn't have much fish in their diet?

Le Cancer Du Poumon,

I believe that you have misread the text. Egyptians in general, ate a lot of fish because they were cheap. But according to the Greek writer Plutarch, the egyptian priests didn't eat fish because they believed in the myth that when Set cut Osiris up into 13 (or 14) pieces and scattered them all over Egypt, Isis found all but one piece which was eaten by a fish.
