Higher Cardio-Ankle Vascular Index Values in Patients With Vestibular Neuritis May Indicate a Better Prognosis

Area of Science:

• Neurology
• Cardiology
• Otolaryngology

Background:

• Vestibular neuritis (VN) presents as sudden vertigo without auditory or cranial nerve issues.
• Current methods for diagnosing VN etiology, particularly vascular causes, are limited.
• Predicting VN prognosis and selecting treatments are crucial and depend on accurate etiology assessment.

Purpose of the Study:

• To evaluate the cardio-ankle vascular index (CAVI) as an indicator for VN prognosis and etiology.
• To explore the relationship between arterial stiffness (CAVI) and VN outcomes.

Main Methods:

• 88 patients with definite VN were analyzed.
• Evaluated factors included age, canal paresis (CP), CAVI, vestibular-evoked myogenic potential asymmetry, and medical history.
• Univariate and multivariate analyses were performed.

Main Results:

• Patients with VN and high CAVI demonstrated a better prognosis compared to those with low CAVI.
• High CAVI was identified as a significant factor for improved percent CP.
• Younger age and less severe initial CP also correlated with better prognosis.

Conclusions:

• CAVI serves as a valuable additional indicator for assessing VN prognosis and potential etiology.
• The findings suggest CAVI's potential application in other conditions involving vascular disorders.
