The microcirculation in patients with arterial hypertension

Abstract

Objective. To study the features of the microcirculation in patients with hypertension, as well as in healthy volunteers by high-frequency Doppler ultrasound.
Materials and Methods. 146 patients (66,1 ± 5,8 years) with hypertension I-II degree was included as I group (mean age was 66.1 +5.8 years). The control group included 34 healthy volunteers (mean age 53.4 +7.8 years).
Results and Conclusions. Patients with hypertension in contrast to healthy volunteers initially have a higher rate of blood flow of microcirculation. Maximum speed at the maximum speed curve more sensitive to disturbances occurring rather than linear speed to the average velocity of the envelope curve. There was correlation between the linear velocities and age, duration of hypertension, SBP and DBP, and creatinine levels. Patients with hypertension with glomerular filtration rate less than 60 ml \ min are stitched or pathological response microcirculation in response to reactive hyperemia and cold test compared with healthy patients and patients with hypertension and preserved renal function.
