The prognostic significance of renal resistive index in essential hypertension.
To the Editor: I read with great interest the paper by Doi et al that was very recently published in Hypertension. The authors demonstrated that, after a mean follow-up period of 3.1 years, renal resistive index (RI) has been found to be an independent predictor of worse cardiovascular and renal outcomes in essential hypertensive patients. Although the study is informative, some additional data...
متن کاملIntrarenal hemodynamics in patients with essential hypertension.
Intrarenal hemodynamics were estimated clinically in essential hypertension. Two-week studies were performed in 30 patients with essential hypertension who were given a regular sodium diet in the first week and a sodium-restricted diet in the second week. Intrarenal hemodynamic parameters such as afferent arteriolar (preglomerular) resistance, efferent arteriolar resistance, and glomerular hydr...
متن کاملResistive Index as a Marker of Renal Pathology in Children with Chronic Kidney Disease; Is It Useful?
Background Chronic kidney disease is a global health concern, its detection and diagnosis in earlier stages is also a great challenge that can alleviate this burden. Kidney biopsy is important to establish histopathological patterns. But, it is invasive. We aimedto evaluate the correlation of renal resistive index (RI) measured by Doppler ultrasound with the prog...
متن کاملRenal resistive index and cardiovascular and renal outcomes in essential hypertension.
Increased renal restive index (RI) measured using Doppler ultrasonography has been shown to correlate with the degree of renal impairment in hypertensive patients. We investigated the prognostic role of RI in cardiovascular and renal outcomes. A total of 426 essential hypertensive subjects (mean age, 63 years; 50% female) with no previous cardiovascular disease were included in this study. Rena...
متن کاملIntrarenal and carotid hemodynamics in patients with essential hypertension.
BACKGROUND The pulsatility index (PI) and resistive index (RI) are used as markers of peripheral vascular resistance. Recently intrarenal PI and RI were introduced for the evaluation of the severity of acute and chronic renal failure, as well as for the diagnosis of renal artery stenosis and kidney graft rejection. In the present study, we evaluated intrarenal PI and RI in patients with essenti...
