Renal resistive index after captopril test by echo-Doppler in essential hypertension.

摘要: In 45 patients with essential hypertension and 15 age-matched normotensive control subjects, the renal resistive index, as an expression of arterial impedance, was determined using Doppler ultrasound. both kidneys index assessed at baseline after captopril test (50 mg orally). moderate severe hypertensives, compared to mild hypertensives significantly higher (P less than .05). Following captopril, increased only in normotensives .05) Univariate multivariate analyses show that duration severity correlated increase basal dynamic conditions. Thus, use by echo-Doppler, could provide useful information for assessment vascular impedance hypertensive patients. This would help us detect evolution disease degrees are arteriolar damage.
