Abstract

Background: Although atherosclerosis is usually thought of as a disease of modernity, the Horus Team has previously reported atherosclerotic vascular calcifications on computed tomographic (CT) scans in ancient Egyptians.

Objectives: The purpose of this study was to compare patterns and demographic characteristics of this disease among Egyptians from ancient and modern eras.

Methods: We compared the presence and extent of vascular calcifications from whole-body CT scans performed on 178 modern Egyptians from Cairo undergoing positron emission tomography (PET)/CT for cancer staging to CT scans of 76 Egyptian mummies (3100 BCE to 364 CE).

Results: The mean age of the modern Egyptian group was 52.3 15 years (range 14 to 84) versus estimated age at death of ancient Egyptian mummies 36.5 13 years (range 4 to 60); p < 0.0001.  Vascular calcification was detected in 108 of 178 (60.7%) of modern patients versus 26 of 76 (38.2%) of mummies, p < 0.001. Vascular calcifications on CT strongly correlated to age in both groups. In addition, the severity of disease by number of involved arterial beds also correlated to age, and there was a very similar pattern between the 2 groups. Calcifications in both modern and ancient Egyptians were seen peripherally in aortoiliac beds almost a decade earlier than in event-related beds (coronary and carotid).

Conclusions: The presence and severity of atherosclerotic vascular disease correlates strongly to age in both ancient and modern Egyptians. There is a striking correlation in the distribution of the number of vascular beds involved. Atherosclerotic calcifications are seen in the aortoiliac beds almost a decade earlier than in the coronary and carotid beds.
