Paper Abstract

New Doppler-Laser flowmetry diagnostic test of functional condition of microcirculation was worked out of find precapillar and postcapillar resistance. Flowmetry was used to measure vasomotion and blood flow after arterial compression, decompression and venous hyperemia were held. Patients of essential hypertension were examined with the help of Doppler-Laser Flowmetry, optical photometry (540 nm). Precapillar resistance included next basis parameters: vasomotion with high frequency (10-16 per/min) and low amplitude, latent time after decompression, large postocclusive reactive hyperemia, absent venous hyperemia. Postcapillar resistance included next basis parameters: vasomotion with low frequency (4-8 per/min) and high amplitude, paradoxical hyperemia in arterial compression, little or absent postocclusive reactive hyperemia, large venous hyperemia. This test-method was applied to select patogenetic treatment of essential hypertension.
