Research by an American-Israeli team shows that the risk of coronary heart disease can be diagnosed after the height and amplitude of the human voice. This method is based on comparing the voices of sick and healthy people by artificial intelligence algorithms. As everyone has access to a voice recorder, for example on a telephone, it can be a cheap and effective method of screening.
Coronary artery disease signaled in the voice
Every year, over 100 Poles are dying of ischemic heart disease. In 90 percent. In some cases, it occurs in people with high blood pressure, diabetes, overweight, or those who abuse alcohol and eat unhealthy. An American-Israeli team of researchers has shown that the analysis of voice samples using artificial intelligence can help predict the risk of coronary heart disease and its complications.

The experiment consisted of two stages. In the first part, doctors asked people suffering from coronary artery disease to record a sample of their voice using a mobile application. — while speaking, reading and singing. The material obtained in this way was analyzed with the use of artificial intelligence in order to find common features concerning, inter alia, pitch and amplitude of the voice. This is how a specific base, a model, was built.

In the second stage of the study, 108 people were asked to submit their voice samples. They were referred for coronary angiography. After two years of observation, scientists found that people with higher compliance with the model were 2,6 times more likely to be hospitalized for symptoms related to coronary artery diseasesuch as chest pain or a heart attack. These individuals also had a 3,1 higher risk of being diagnosed with coronary heart disease on subsequent angiography, or had a positive exercise test, which is an indicator of the risk of coronary heart disease.

Where does this dependence come from?
Where does this dependence come from? It is not known. Voice production and control are also largely unconscious and controlled by the autonomic nervous system. The same chip is responsible for controlling the functions human heart. And this is most likely the key to understanding the relationship between voice and disease.
