People living in conditions of chronic noise are at risk of stroke and heart attack - Cardiologists

Long and loud sound effects stimulate the activity of the amygdala of the brain, which reacts to stress and emotions, which leads to inflammation of the brain's blood vessels, and leads to cardiovascular consequences.

According to the results of the experiment, cardiologists from the Massachusetts General Hospital in Boston concluded that people living in conditions of chronic noise put themselves at considerable risk of stroke and heart attack. These conclusions were preceded by a long scientific work, in which 499 patients with an average age of 56 years, who had never before suffered from oncological diseases and pathologies of the heart, took part. Anamnesis was collected from all volunteers, and simultaneously positron emission tomography was performed, which made it possible to assess the activity of the amygdala, and computed tomography of their brain and blood vessels. According to the results of the study and medical records, all participants identified a cardiovascular risk.
After 5 years during the second stage of the study, scientists found that 40 volunteers had a stroke or a heart attack over a specified period. To identify the relationship between cardiovascular disease and noise exposure, the level of the latter was measured in the homes of each research participant, and the level of noise from the aviation and roadmap created by the State Department of Transportation was assessed. As it turned out, the activity of the amygdala, and accordingly the degree of damage to the blood vessels of the brain, is directly proportional to the amount of constantly acting noise. At the same time, the risk of developing a heart attack or other pathologies of the heart increased three times.
The results of scientific work require further study, including the establishment of mechanisms for this dependence, and also to determine whether it is possible to reduce the risk by reducing the noise level. The data will be presented at the upcoming congress of the American Heart Association in Chicago.
