The Relationship of Renal Augmented Velocity Index With Ventricular-Arterial Coupling in Comparison to Renal Resistive Index Analysis by Means of Arterial and Ventricular Elastances in Hypertensive Patients

The study conducted on untreated hypertensive patients to explore the association between a new Doppler parameter called the augmented velocity index (Avi) and ventricular-arterial coupling (VAC), effective arterial elastance (Ea), and left ventricular end-systolic elastance (Ees). The study aims to determine the potential clinical utility of Avi in assessing arterial hemodynamics and its correlation with cardiovascular risk factors in hypertensive patients with normal kidney function. The findings suggest that Avi is strongly associated with Ea and VAC, highlighting its potential as a sensitive measure for detecting subtle changes in cardiovascular performance. Further research is needed to validate its usefulness in different disease states and understand the underlying mechanisms. The study's importance lies in its investigation of the new Doppler parameter, Avi, and its potential clinical significance in assessing arterial hemodynamics and cardiovascular (CV) performance in untreated hypertensive patients with normal kidney function. Avi's strong association with effective arterial elastance (Ea) and ventricular-arterial coupling (VAC) suggests its sensitivity in detecting early changes in CV function. If validated, Avi could become a valuable noninvasive tool for identifying patients at higher CV risk and guiding therapeutic approaches in hypertension management. Understanding this parameter's significance may lead to improved risk prediction and personalized treatment strategies for hypertensive individuals, ultimately reducing the burden of cardiovascular diseases.</p
