[The effect of cardiovascular, endocrine and metabolic diseases on hearing]

Area of Science:

• Otorhinolaryngology
• Cardiology
• Internal Medicine

Context:

• Chronic hearing impairment is often speculatively linked to internal diseases.
• Previous assumptions suggested a correlation between cardiovascular conditions and hearing loss.
• This study investigates hearing faculty in patients with coronary artery disease and hypertension.

Purpose:

• To investigate the relationship between coronary artery disease, hypertension, and hearing ability.
• To compare the hearing faculty of patients with specific internal diseases against healthy age-matched controls.
• To evaluate the validity of linking chronic hearing impairment to cardiovascular, metabolic, and hormonal conditions.

Summary:

• Audiometric assessments were conducted on 111 patients with coronary artery disease (30-59 years) and 90 patients with hypertension (16-60 years).
• Results indicated only minor differences in hearing faculty between the patient groups and healthy individuals.
• The study found no significant evidence that coronary or hypertensive patients are harder of hearing than their healthy counterparts.

Impact:

• Challenges the common belief that cardiovascular diseases directly cause significant chronic hearing impairment.
• Highlights the importance of audiometric standards in interpreting hearing ability in medical risk groups.
• Advises caution against unsubstantiated claims linking hearing loss to systemic diseases like cardiovascular, metabolic, or endocrine disorders.
