摘要：
FIELD: medicine.SUBSTANCE: invention refers to medicine, specifically cardiology. A contour analysis of a pulse wave recorded by photoplethysmography is conducted in individuals being tested. A rigidity index is used to assess the state of a greater vascular wall. If the rigidity index is more than 8 m/s, the structural changes of the great vascular wall (Sk+) are recorded, and the rigidity index less than 8 m/s shows no structural changes of the greater vessels (Sk-). That is combined with a computer-assisted capillaroscopy of a periungual bed and dorsal finger skin. A capillary remodelling more than 1.33, rest capillary network density more than 45 drop/mm2, as well as capillary network density after a venous occlusion test more than 56 drop/mm2, show no structural changes of the microvessels (Sm-). If observing abnormal values of at least one parameter, the structural changes of the microvessels (Sm+) are stated. That is followed by an occlusion photoplethysmography to assess the functional changes of the greater vessels and microvasculature on the basis of a phase shift and an occlusion index. If the phase shift is less than 10 m/s, the functional disturbances of the greater vessels (Fk+), and the value more than 10 m/s shows no functional disturbances (Fk-). If the occlusion index is more than 1.8, the functional changes of the microvascular wall (Fm+) are stated, while the given value less than 1.8 shows no functional changes (Fm-). The structural-functional changes of the greater vessels, microvasculature and combinations thereof are detected to provide a basis to assess the blood flow state. A combination (Fk-Sk- Fm-Sm-) show no disturbances of the blood flow considered as degree 0. The combination (Fk-Sk- Fm+Sm-), (Fk+Sk- Fm+Sm-), (Fk+Sk- Fm-Sm-) provides considering the degree 1 blood flow involvement. The combinations (Fk-Sk+ Fm-Sm-) and (Fk+Sk+ Fm-Sm-) enables assessing the degree 2 involvement. The combinations (Fk-Sk+ Fm+Sm-) provide the degree 3 invol
