Resumen
The study of blood vessel reactivity to local thermal impact could be used for assessment of the endothelial function in patients with increased cardio-metabolic risk (hypertension disease, diabetes mellitus, dyslipidemia). Moreover, it can be applied for revealing the subclinical impairments of blood flow in patients with rheumatologic pathology. Imaging photoplethysmography is a basis for the development of medical equipment capable of contactless assessment of the endothelial function in various skin regions.
