Scientists have shown the impact of obesity on cardiovascular disease

Ученые доказали влияние ожирения на сердечно-сосудистые заболевания

It is proved that the problem shape is not a risk factor and cause of heart problems.

Long known that obesity causes harm to the body. Musculoskeletal strained and excess cholesterol clogs the blood stream. Moreover, the heart has to supply blood surge in the body. However, the weight was considered a secondary factor. In the new study, scientists have shown the impact of obesity on cardiovascular disease.

To confirm the Association of body weight and heart disease, the researchers used Mendelian randomization. This method, which allows to separate the risk factors of the disease, its immediate causes. Researchers from the Karolinska Institute (Sweden) studied 96 genetic combinations 367 thousand patients with different body mass, to find a connection with 14 cardiovascular diseases.

As it turned out, the increase in body mass index and fat concentration leads to aortic valve stenosis. In other words, the aorta is not receiving sufficient blood. Randomization Mendel also pointed out the relationship of body weight with hypertension, ischemic heart disease, and thrombosis. Previously it was thought that excess weight exacerbates the disease.

The study authors emphasize that most of the volunteers obesity is not caused by a genetic predisposition, and physical inactivity and improper nutrition.
