| Summary: | Aim. To identify individual and typological functional features of peripheral blood flow and assess microcirculation (MC) dynamics after a single-dose administration of nifedipine in patients with arterial hypertension (AH).Material and methods. Laser Doppler flowmetry (LDF) was used for the MC assessment in 39 patients with Stage II–III AH.Results. Marked variability in peripheral blood flow parameters was demonstrated for AH patients. Three main LDF types were identified: aperiodic (ApT), hyperemic, and hypoemic. Single-dose administration of nifedipine (20 mg) resulted in a similar antihypertensive effect across all patient groups. Positive MC dynamics was observed, which manifested in a marked increase in the number of patients with ApT (the most balanced type of peripheral blood flow regulation) and increased input of pulse blood filling into hemoperfusion.Conclusion. In AH patients, nifedipine-induced changes in peripheral blood flow were associated with an increased number of participants with ApT, as the most balanced type of MC regulation. |
