Chronic cardiovascular pathology and hearing loss in the aged

Area of Science:

• Audiology
• Cardiology
• Gerontology

Background:

• Cardiovascular diseases are prevalent in aging populations.
• Hearing loss is a common comorbidity in the elderly.
• The relationship between cardiovascular health and auditory function requires further investigation.

Purpose of the Study:

• To investigate the correlation between chronic cardiovascular disturbances and hearing loss in aged individuals.
• To compare auditory function in elderly subjects with and without cardiovascular pathology.

Main Methods:

• Two groups of elderly subjects were compared: apparently healthy individuals and those with clinically evident chronic cardiovascular pathology.
• All subjects underwent pure tone audiometry, a speech discrimination test, the Speech Intensity Spectral Integration (SISI) test, and a Tone Decay Test (TDT).

Main Results:

• A significant difference in pure tone threshold audiometry was observed between subjects with and without cardiovascular symptoms.
• Speech discrimination and Tone Decay Test results were comparable between the two groups, suggesting a specific impact on pure tone perception.

Conclusions:

• Chronic cardiovascular disturbances are associated with significant differences in pure tone hearing thresholds in the elderly.
• Further research is warranted to understand the mechanisms linking cardiovascular health to specific aspects of hearing loss.
