Insights
Hypertension can lead to hearing loss, with vascular endothelial dysfunction playing a key role. Biomarkers like endothelin-1 and von Willebrand factor were elevated in hypertensive patients with hearing loss.
Area of Science:
- Cardiovascular Medicine
- Otolaryngology
- Vascular Biology
Background:
- Hypertension is a known risk factor for hearing loss.
- The precise mechanisms linking hypertension and hearing loss remain unclear.
- Vascular endothelial dysfunction is implicated in cardiovascular diseases.
Purpose of the Study:
- To investigate the role of vascular endothelial dysfunction in hypertensive patients with hearing loss.
- To identify potential biomarkers associated with hearing loss in hypertension.
- To assess the diagnostic value of endothelial function tests and biomarkers.
Main Methods:
- A cohort of 216 hypertensive patients was divided into groups with and without hearing loss.
- Pure tone audiometry (PTA) was used to assess hearing.
- Endothelial function was evaluated using reactive hyperemia index (RHI), endothelin-1 (ET-1), and von Willebrand factor (vWF).
Main Results:
- Patients with hypertension and hearing loss showed significantly higher levels of ET-1 and vWF (P < .05).
- RHI, ET-1, and vWF were identified as factors associated with hearing loss.
- The area under the ROC curve (AUC) indicated diagnostic potential for RHI (.652), ET-1 (.706), and vWF (.617).
Conclusions:
- Vascular endothelial dysfunction appears to contribute to the development of hearing loss in hypertensive individuals.
- ET-1 and vWF may serve as potential biomarkers for identifying hypertension-related hearing loss.
- Further research is warranted to elucidate the specific pathways involved.
Abstract:
Hypertension can cause hearing loss, but there is no clear definition of the mechanism(s) involved. The study aimed to explore the role of vascular endothelial dysfunction in hypertension with hearing loss. Patients with hypertension were divided into two groups based on hearing loss. Pure tone audiometry (PTA) and endothelial function testing were performed. A total of 216 (432 ears) hypertensive patients were divided into hypertension with hearing loss group (n = 104) and hypertension without hearing loss group (n = 112). The vascular endothelial biomarkers, ET-1 (endothelin-1) and vWF (von Willebrand factor) were significantly higher (P < .05) in the hypertension with hearing loss group. RHI (reactive hyperemia index), ET-1, and vWF were the factors related to hearing loss. The area under the receiver operating characteristic (ROC) curve (AUC) of RHI in the diagnosis of hypertension with hearing loss was .652 (95% CI .552-.751, P = .005), and the Youden index was 26.2%. The AUC of ET-1 was .706 (95% CI .612-.799, P = .001), and the Youden index was 38.9%. The AUC of vWF was .617 (95% CI .512-.721, P = .003), and the Youden index was 28.1%. Vascular endothelial dysfunction may play a role in the pathogenesis of hypertension with hearing loss.
