Relationship between hypertension and hearing disorders in the elderly

Area of Science:

• Gerontology
• Cardiology
• Otolaryngology

Background:

• Hypertension is a prevalent condition in the elderly population.
• Hearing impairment is a common age-related sensory deficit.
• The link between hypertension and hearing disorders requires further investigation.

Purpose of the Study:

• To examine the association between hypertension and the prevalence and severity of hearing disorders in elderly individuals.
• To explore the impact of hypertension, serum lipids, and disease duration on age-related hearing loss.

Main Methods:

• A prospective case-control study was conducted with 55 hypertensive elderly males and 55 age-matched controls.
• Hearing function was assessed using pure-tone audiometry and auditory brainstem response (ABR).
• Serum triglyceride and cholesterol levels were measured to evaluate lipid profiles.

Main Results:

• Auditory thresholds significantly worsened with age in hypertensive patients compared to controls (p < 0.05).
• Auditory brainstem response revealed prolonged latencies (wave V, I-VIPL, III-VIPL) in hypertensive subjects.
• The duration of hypertension and its complications were found to influence the degree of hearing impairment.

Conclusions:

• Hypertension, especially when accompanied by elevated triglycerides and cholesterol, contributes to accelerated hearing loss in the elderly.
• Prolonged hypertension and its associated complications are significant factors in the development of hearing disorders in older adults.
• Managing hypertension and its metabolic consequences may be crucial for preserving hearing in the aging population.
