Studies show that markers of metabolic syndrome independently increase the risk of developing myocardial infarction and stroke.
Metabolic syndrome (MS), or syndrome X, which is a combination of various metabolic disorders and clinical manifestations, is considered one of the most important problems of modern society.
The leading sign of metabolic syndrome is abdominal obesity with fat deposits predominantly on the stomach, which is estimated by the body mass index. In addition, allocate additional criteria for MS:
- Arterial hypertension - increase in blood pressure more than 135/85 mm Hg;
- Insulin resistance, that is, a violation of the sensitivity of cells and tissues to insulin, which leads to the development of type 2 diabetes;
- Increased levels of triglycerides in the blood;
- Lowering the level of "good" cholesterol (high density lipoprotein), which protects against the development of atherosclerosis.
A combination of obesity and two other or any other signs allows you to talk about MS.
Statistics show that the prevalence of MS increases worldwide, and above all - in developed countries, and ranges from 10 to 35%. If it was previously thought that MS is affecting mostly adults, now pediatricians are confronted with an increase in this pathology among children and adolescents.
It has long been known that MS leads to the development of a number of serious diseases, including diabetes, atherosclerosis, fatty liver disease, and others.
Scientists from the University of California (USA) conducted a major epidemiological study on MS. The work showed that the presence of each of the signs of the MS significantly increases the risk of acute heart and brain disease.
The researchers analyzed the results of an examination of nearly 10,400 people who participated in the third major national study on health and nutrition among Americans aged 20 to 89 years (NHANESIII study).
Experts examined the volunteers for the signs of the MS and asked them in special questionnaires to indicate a previous stroke or myocardial infarction.
As it turned out, MS was present in 24% of the examined individuals. Moreover, the presence of MS, according to researchers, doubled the risk of acute circulatory disorders.
A great contribution to the development of stroke and heart attack is also contributing to other signs of the MS. A high level of triglycerides increases the risk by 66%, high blood pressure - by 44%, low "good" cholesterol - by 35%, and insulin resistance - by 30%.
Researchers consider the findings to be very important. The prevalence of MS is increasing every year. Moreover, the leading cause of its development, doctors see refusal to adhere to habits of a healthy lifestyle, namely proper nutrition, regular physical activity, maintenance of normal body weight.
Doctors warn that such a trend is very dangerous, because it increases the risk of widespread cardiovascular disease and metabolic disorders.
The results of a study by American scientists have been published in the Journal of the American Association of Cardiovascular Circulation Diseases.
