In Samara, they learned how to detect heart disease by skin

Scientists from Samara University have developed an innovative method for diagnosing chronic heart failure, which does not require intervention in the human body. This method, the first in the world, is based on irradiating the skin of patients using a laser.

According to the researchers, this approach represents a significant advance in the field of medical diagnostics and can become a worthy alternative to existing invasive methods. The registration procedure is carried out using Raman spectroscopy, which allows obtaining unique spectral profiles of the skin of patients.

An important advantage of the new approach is the absence of the need for additional reagents and surgical interventions. Instead, scientists target the inside of the patient’s forearm with a laser. The interaction of radiation with skin tissues leads to energy changes, which are then recorded using a special probe.

After conducting clinical studies, it was found that the analysis of the unique spectral profiles of the skin allows you to reliably determine the presence of chronic heart failure in patients. To process the data obtained, scientists used machine learning methods, which increased the accuracy and reliability of the results.

This innovative technique represents a significant step in the field of heart disease diagnostics, providing a reliable and non-traumatic alternative for patients. It can significantly improve heart failure detection and treatment initiation, which improves the quality of healthcare and increases the chances of successful recovery for those affected by the disease. The results of the study were published in the Journal of Biophotonics.
