Scientists from the Mayo clinic, USA, found that the same symptom points to the risk of both the cardiovascular and cancer diseases.
We are talking about microvascular endothelial dysfunction (ED). It is a violation of the normal functioning of the endothelium — layer of cells covering the inside of small blood vessels. The vessels become more brittle, decreasing their tone.
The main causes of dysfunction are hypertension, high cholesterol, obesity and diabetes. The main symptom of the condition is chest pain.
Changes in dose rate affects the small arteries in the heart, which impairs their ability to expand and restricts the flow of blood rich in oxygen. It is therefore considered that the presence of the patient MED increases the risk of developing heart disease.
In the study, 488 for 12 years been treated for cardiovascular diseases. Have 211 of them in the last six years, noted microvascular endothelial dysfunction.
It turned out that the risk of cancer in patients with a dose rate considerably higher than those who have vessels operating normally — 9.5 and 3.7 percent, respectively.
Microvascular endothelial dysfunction may be a useful marker to predict cancer risk, said the scientists.
As a rule, the dose rate is about five years earlier than the diagnosed cancer.
While the relationship between dose rate and cancer risk was more pronounced among men and patients with hypertension, coronary artery disease, as well as smokers and those who suffer from obesity.
