Abstract
Objective. To study blood velocity in arterioles in hypertensive patients by doppler.
Design and methods. We assessed blood velocity in 90 patients with essential arterial hypertension (AH) and in 83 patients with type 2 diabetes mellitus (DM2) with AH («Minimax-Doppler-K»), and in 102 control subjects: during systole (Vs, cm/s), diastole (Vd, cm/s) and during the mean blood flow cycle (Vm, cm/s). Then spontaneous changes of blood velocity were recorded during 1 minute. In patients with DM2 association between blood velocity and disease duration was studied. In 43 hypertensive patients Vs and Vd were defined after treatment.
Results. Hypertensive patients had the highest blood velocity, lower values were defined in healthy people, and hypertensive subjects with DM2demonstrated the lowest blood velocity. Fluctuations in blood velocity during systole were the highest in healthy people, less in hypertensives and the smallest in subjects with DM2 and AH. Variations of blood velocity during diastole were the highest in AH patients, less in patients with DM2 with AH and the least in healthy subjects. Blood velocity in arterioles is lower in patients with the longer duration of DM2. In treated hypertensive patients blood velocity in arterioles reduces. Conclusion. By assessment of blood flow velocity in arterioles we can evaluate the functional state of these vessels in hypertensive patients.
