Clues of Heart Disease Found in 16th-Century Mummies

 16th-Century Mummies
It is always fascinating to see what we can learn from our ancestors. How they lived without intervention or use of modern utilities, the knowledge that we have today and much more that are home to the current time. But what about looking at diseases present today? Were the same diseases, found today, present in our ancestors too? Well that may be a question that is hard to answer since asking our ancestors is totally out of the question. So what about CT scans? Researchers from Brigham and Women’s Hospital did just that.

Researchers found evidence of heart disease in mummies from the 16th century.

CT Scan on 16th century Mummies to Discover Heart Disease: 


Researchers subjected 5 mummies from 16th century Greenland to a CT scan and the results were astounding. The research team began to look for evidence of plaque in the mummies and were not disappointed. Plaque in the arteries is indicative of atherosclerosis, one of the leading causes of death in the US today.

The high resolution scans showed that there were calcium deposits in the blood vessels in the chest of the mummies. There were four adults and a child from the Inuit community that were tested for heart disease and in all four were these telltale deposits of calcium discovered.

The images from the five mummies was scanned and even shown on National Geographic in a show titled “Explorer”. The research into the mummies from Greenland was only a small part of the main research project. A project to discover heart disease in early hunter gatherer or pre industrial civilization is the main project behind the research into mummies form 16th century Greenland.

A Look at the Past and Heart Disease: 


Researchers have looked at mummies form Egypt to Mongolia and now more recently to Greenland for evidence of atherosclerosis- a heart disease. The Greenland mummies were of particular interest to researchers because of their particular diet. The Inuit community mainly consumed fish and small sea mammals.

A fish diet is considered good for a healthy heart, so finding heart disease in a community thought to have had a largely fish diet seems somewhat surprising. While others may be surprised with the findings, researchers were not. The relationship between a fish diet and a healthy heart is not really proven. Finding heart disease in these mummies would require further investigations.

Fish rich in omega 3 is good for the heart but certain other fish are rich in cholesterol and contain things such as mercury and PCBs that are touted as causes for heart disease.

Other Factors that may have Caused Heart Disease: 


While diet may be a main cause of causing heart disease, there could be other factors at play that can cause heart disease. Lifestyle factors such as excessive smoke while cooking could also be one of the reasons why these mummies showed signs of heart disease.

Researchers are not taking the results seriously as they are based on a small sample of population and not indicative of the entire population.
