Abstract
Aim. To access the effect of lisinopril (diroton) on cerebral circulation and blood rheology in patients
with arterial hypertension stage II.
Material and methods. The trial included 37 patients (16 males, 21 females) with a mean arterial
hypertension (AH) history 15.9 ± 5.6 years. Diroton was given in a dose 10-40mg/dayfor 6 months.
Cerebral circulation (total cerebral circulation and venous outflow - TCC and VOF) was accessed by
means of doppler ultrasonography. Blood and plasm rheology was determined using a rotational viscozymeter ACP-2.
Instrumental tests were performed at baseline and at the end of the study.
Results. Rheology tests showed that diroton-treated patients achieved a significant decrease in blood
viscosity in high, moderate and low shear stress and plasma viscosity, a decrease in platelet aggregation
index and an increase in the index of erythrocytic deformability. All these changes were accompanied
with a significant fall in fibrinogen and hematocrit. Doppler ultrasound revealed an insignificant
increase in TCC and VOF.
Conclusion. Diroton significantly improved impaired blood rheology and viscosity in AH patients as
well as cerebral hemodynamics in patients with subnormal cerebral circulation and venous outflow at
baseline.
