Cardiovascular diseases pose a serious threat to the life of the modern inhabitant metropolis, neglecting physical activity and maintaining a healthy lifestyle. However, recent studies show that not only modern humans, but their ancient ancestors suffered from excess cholesterol in the arteries, which gives the right to assume that in ancient times heart disease was much more widespread than previously thought.
Atherosclerosis — a disease of ancient
Despite the fact that atherosclerosis is a chronic disease, it is also progressive causing narrowing of the lumen in the walls of arteries. This disease affects most of the population from the age of 10-15 years. During the development of this disease under threat may be not only the cardiovascular system but also any other organ of the human body. Closing the lumen of the artery, atherosclerotic plaque interferes with adequate nutrition of the organ or tissue, causing necrosis and disruption of the body up to its full failure.
According to statistics, the total mortality rate due to diseases of the cardiovascular system is an average of 185 people per 100 thousand population, and in Russia this figure is much higher and reaches up to 800 people.
Study of the arteries in mummies
In order to understand what exactly is rooting our ancient ancestors, the researchers examined and analyzed the arteries embalmed mummies in age from 18 to 60 years, the remains of which date from 2000 BC to 1000 BC from South America and ancient Egypt. The study, one of the mummies, scientists have discovered the early stage of atherosclerosis, which is characterized by the accumulation of sclerotic plaques on artery walls, thereby restricting blood flow internal.
Having studied the sections of arteries, the length of which was only a few centimeters, the researchers found damage to the walls of blood vessels due to the accumulation of cholesterol that blocks arteries and provokes heart attacks. This study is the first evidence that atherosclerosis affects not only the modern humanity, and there is a very long time.
Earlier studies have been conducted in which was discovered later stage of formation of arterial plaque in the mummies from Greenland, Dating back more than 500 years ago and Egyptian mummies, the embalming which took place more than 3,000 years ago. Thanks to modern technology, scientists have found out that the most ancient man, a mummy which was found in the Alps and is named etti, most likely died because of heart attack caused by atherosclerosis.
Currently, scientists are of the opinion that the deposition of cholesterol on the walls of the arteries is a protective mechanism by which wound healing occurs. This mechanism is activated when exposed to various infections, injury, and under the action of toxins and smoke that can damage the inner lining of the artery.
With inflammatory reaction, which in turn is a normal protective manifestation of the body, the walls of the arteries are subjected to accumulation of leukocytes, which subsequently leads to the accumulation of cholesterol.
