Essential hypertension can lead to hearing loss, even before symptoms are noticeable. This study found impaired hearing function in hypertensive patients, particularly those with retinal arteriosclerosis.
Area of Science:
- Otorhinolaryngology
- Cardiology
- Audiology
Context:
- Essential hypertension is a prevalent cardiovascular condition.
- Hearing impairment is a growing public health concern.
- The relationship between hypertension and hearing loss requires further investigation.
Purpose:
- To investigate the characteristics of hearing loss in patients with essential hypertension.
- To assess the impact of retinal arteriosclerosis on hypertension-related hearing deficits.
- To evaluate auditory function using pure tone audiometry and distortion product otoacoustic emissions.
Summary:
- Hypertensive patients, especially those with retinal arteriosclerosis, exhibited significantly higher pure tone hearing thresholds compared to controls.
- Distortion product otoacoustic emissions (DPOAE) amplitudes were reduced in both hypertensive groups (A and B) across frequencies from 1000 to 8000 Hz.
- A lower DPOAE detection rate was observed in hypertensive patients with retinal arteriosclerosis (Group B) at 4000 Hz.
Impact:
- Hypertension is identified as a risk factor for auditory apparatus degeneration.
- Subclinical hearing impairment may occur in hypertensive individuals.
- Early audiological assessment is crucial for hypertensive patients to detect potential hearing loss.

Hypertension and Regulation of Blood Pressure
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
