“We have conducted studies involving various age groups who have recovered from COVID-19. It turned out that 30% of students had micro-vessels which malfunctioned after a mild course of the disease. As for those over 60, these complications were recorded in 60% of cases. The main danger of the identified consequences is the change in internal reactions to physical activity and sudden changes in temperature. That is, if a person with such a complication begins to actively engage in sports shortly after a general recovery, he has an increased risk of thrombosis with all the ensuing consequences, and a fatal outcome is possible,” Elena Turovinina, head of the Department of Medical Prevention and Rehabilitation with TyumSMU, explained.
“In diagnostics, we use a device for the optical non-invasive probing of tissues with laser radiation. It registers the signal of moving red blood cells, which allows us to evaluate the blood flow in certain areas of the skin. Also, using different wavelengths, the device brings atoms into an excited state, highlighting certain biomarkers in the micro-vessels of the skin. Previously, this equipment was used only on the ISS to monitor the health of cosmonauts, and for the first time we used it in practical healthcare for a specific task,” Professor Turovinina added.
