New method for early diagnosis of high blood pressure

Scientists from Moscow University, the Moscow Institute of Physics and Technology and the National Research Technological University, together with the University of Copenhagen, have developed a new method for diagnosing high blood pressure.

The researchers note that this method is based on the analysis of red blood cells and the hemoglobin present in them. This method allows diagnosing high blood pressure (blood pressure level of 140 mm Hg or more) in the early stages. In cardiovascular diseases, the ability of red blood cells to carry oxygen is impaired, which leads to an increase in blood pressure.

“Our joint study showed that the use of a method based on the Raman scattering effect (Raman spectrometry is an optical method for studying particle radiation) makes it possible to detect pathological changes occurring in cells,” says Sergei Novikov, senior researcher at the Center. on photonics and 2D materials of the Moscow Institute of Physics and Technology. early, and other methods are not suitable for diagnosing this disease.”

To determine the changes that occur in hemoglobin molecules during high blood pressure, the researchers examined blood samples from mice with high blood pressure and blood samples from mice without it. And they confirmed its effectiveness in tests on people with high blood pressure, pulmonary hypertension and myocardial infarction at the Myasnikov Cardiology Center.
