Objectives

Narrative objectives1

The Hemodialysis Vascular Sound Index (HVSI), derived from vascular murmur analysis, may provide a simple, objective alternative. This study evaluates the diagnostic performance of the HVSI in detecting VA stenosis and reduced flow volume (FV).

Results

HVSI showed a significant correlation with FV (R^2 = 0.58) and RI (R^2 = 0.32). When the threshold for FV was 500 mL/min or less, 400 mL/min or less , and 350 mL/min or less, the sensitivity, specificity, and AUC of the HVSI were 86.3% to 94.4%, 78.7% to 82.9%, and 0.90 to 0.94, respectively. The diagnostic accuracy was higher for non-branching vessels.

HVSI showed significant correlations with FV (R^2= 0.58) and RI (R^2 = 0.32). For FV thresholds 500 mL/min or less, 400 mL/min or less, or 350 mL/min or less, HVSI showed sensitivities of 86.3-94.4%, specificities of 78.7-82.9%, and AUCs of 0.90-0.94. Diagnostic accuracy was higher in non-bifurcated vessels.
