Researchers have uncovered a significant connection between hearing loss and heart health. The study found that people with hearing loss can face a higher risk of developing heart failure. The researchers investigated the underlying reasons for this link, exploring the mental and physical factors that might explain how hearing problems could relate to heart health.
Why it matters
The study reveals a strong connection between hearing loss and increased heart failure risk. Psychological distress from hearing problems appears to be a key factor in this link, indicating the mental-health challenges faced by people with hearing loss could significantly impact their heart health.
By the numbers
- Researchers analyzed data from 164,431 people in the UK Biobank. The average age was 56, 55% were women. None had heart failure at the start.
- The study followed people for about 11.5 years on average.
- 4,449 participants, nearly 3%, developed heart failure during the study.
- Hearing ability was measured objectively.
Key findings
Compared to people with normal hearing, those with hearing difficulties faced higher heart failure risks. Individuals with insufficient hearing had a 15% increased risk, while those with poor hearing saw a 28% higher risk.
A closer look
Hearing problems can make social interaction difficult. This can lead to social isolation, psychological distress, and anxiety. These factors were strongly linked to hearing levels in the study, especially among those not using hearing aids.
Psychological distress was a significant factor in the link between hearing loss and heart failure. It accounted for 17% of the increased risk among those without hearing aids.
These psychological factors may activate stress responses in the body. This can increase inflammation and oxidative stress. Over time, this might speed up hardening of the arteries and contribute to heart problems, like heart failure.
The study also suggests a biological link. The inner ear has many small blood vessels. It needs a high metabolism. This might make it sensitive to general vascular problems. Therefore, hearing impairment might be an early sign of wider cardiovascular issues.
The takeaway
The study found a clear link between hearing loss and increased heart failure risk, with psychological distress emerging as a critical factor. While hearing aids can improve hearing, they may not completely mitigate the underlying health risks.
The findings point to a take-charge approach to health management:
- Include hearing assessments as part of cardiovascular risk evaluation
- Provide psychological support for people with hearing loss to reduce heart failure risk
