Aim: to analyze the influence of quinapril on aortic PWV, whole blood viscosity (WBV), shear stress in the ascending aorta (AA) and common carotid artery (CCA), prometaloproteinase-1 (proMMP-1) and its tissue inhibitor (TIMP-1) plasma concentration in patients with essential arterial hypertension (HT).

Methods: 55 patients, (mean age 55,8 ± 13,8 yrs.) with HT 1 and 2 gr. were treated with quinapril in stepwise increased doses from 10 to 40 mg/d till BP goal <140/90 mmHg was achieved. At baseline and then after 3 and 6 months of treatment PWV, WBV, proMMP-1 and TIMP-1 were determined. Shear stress in AA and CCA was calculated from WBV, internal vessel diameter and blood flow velocity (Vmax) measured ultrasonographycally.

Results: After 6 months of treatment by quinapril we observed decrease of BP (155.6/92.0 mmHg vs. 135.9/82.9 mmHg, p<0.001), PWV (10.35 m/s vs. 9.64 ms, p<0.001), WBV (5.14 cP vs. 4.86 cP, p<0.05) and TIMP-1 (111.0 ng/ml vs. 94.1 ng/ml, p<0.001) and increase of Vmax in AA (127.1 cm/s vs.131.3 cm/s, p<0.05, Vmax in CCA (69.9cm/s vs. 78.4 cm/s, p<0.05) and shear stress in CCA (22.2 dyne/cm2 vs. 24.7 dyne/cm2 , p<0.05). Significant positive correlation was observed for PWV and TIMP-1, and negative correlations for PWV and Vmax in AA, PWV and Vmax in CCA, as well as PWV and shear stress in CCA.

Conclusions: Quinapril reduces arterial stiffness by inhibition of collagen metabolism. This effect is mediated by influence on arterial shear stress.
