Add a Hearing Test to Your Heart-Healthy Lifestyle
Washington, DC, September 15, 2015 — The Better Hearing Institute (BHI) is urging people to check their hearing for World Heart Day on September 29 in response to a growing body of research showing a link between cardiovascular and hearing health. To help people determine if they need a comprehensive hearing test by a hearing healthcare professional, BHI is offering a free, quick, and confidential online hearing check at www.BetterHearing.org.
Dr. Stacy Kerschen and Raymond Hull, PhD, professor of communication sciences and disorders in audiology and neurosciences at Wichita State University, recently completed research analyzing 84 years of work from scientists worldwide on the connection between cardiovascular health and the ability to hear and understand what others are saying. Their work, which reviewed 70 scientific studies, confirmed a direct link.
According to Hull, “Our entire auditory system, especially the blood vessels of the inner ear, needs an oxygen-rich nutrient supply. If it doesn't get it due to cardiovascular health problems, then hearing can be affected."
While there are many possible causes of hearing loss, cardiovascular disease appears to exaggerate the impact of those causes and intensify the degree of hearing decline, says Hull. This compounded effect not only increases the difficulty a person experiences in perceiving what has been said, but also diminishes their ability to make sense of what they hear with speed and accuracy.
Could hearing loss be an early sign of cardiovascular disease?
Research is ongoing, but a number of findings suggest that keeping track of your hearing may help you monitor your cardiovascular health as well.
“The inner ear is so sensitive to blood flow that it is possible that abnormalities in the cardiovascular system could be noted here earlier than in other less sensitive parts of the body,” according to David R. Friedland, MD, PhD, Professor and Vice-Chair of Otolaryngology and Communication Sciences at the Medical College of Wisconsin in Milwaukee.
In Dr. Friedland’s own 2009 study, published in The Laryngoscope, he and fellow researchers found that audiogram pattern correlates strongly with cerebrovascular and peripheral arterial disease and may represent a screening test for those at risk. They even concluded that patients with low-frequency hearing loss should be regarded as at risk for cardiovascular events, and appropriate referrals should be considered.
More recently, a 2014-published study by researchers at the University of Wisconsin in Madison found that the risk of hearing impairment was significantly greater in people with underlying atherosclerosis, or hardening of the arteries, than in those without vessel abnormalities, suggesting that hearing loss may be an early sign of cardiovascular disease in apparently healthy people, according to an article in The Wall Street Journal. The study involved a large cohort of middle-aged participants and showed that hearing loss is common in people in their forties. http://ow.ly/RTuu9 http://ow.ly/RTuBJ

5 Heart-Healthy Reasons to Get a Hearing Test
- Six decades of research points to heart-hearing health link. A comparative review of more than 60 years of research found a correlation between cardiovascular and hearing health. Specifically, the study authors concluded that the negative influence of impaired cardiovascular health on both the peripheral and central auditory system—and the potential positive influence of improved cardiovascular health on these same systems—have been found through a sizable body of research. http://ow.ly/BqqPy
- The ear may be a window to the heart. Some experts find the evidence showing a link between cardiovascular and hearing health so compelling that they say the ear may be a window to the heart. They encourage collaboration between hearing care providers, cardiologists, and other healthcare professionals. Some even call on hearing care professionals to include cardiovascular health in patient case history and to measure their patients’ blood pressure. http://ow.ly/Sc1j1; http://ow.ly/BqYsK; http://ow.ly/BqZdt
- The same lifestyle behaviors that affect the heart impact hearing. More evidence of the interconnectedness between cardiovascular and hearing health is found in three studies on modifiable behaviors: One found that a higher level of physical activity is associated with a lower risk of hearing loss in women. Another revealed that smokers and passive smokers are more likely to suffer hearing loss. And a third found that regular fish consumption and higher intake of long-chain omega-3 polyunsaturated fatty acids are associated with a lower risk of hearing loss in women. Coincidence? Or does it all come back to blood flow to the inner ear? Research is ongoing. http://ow.ly/BqrlJ; http://ow.ly/Bqsz0; http://ow.ly/Sc4Iw
- Addressing hearing loss improves quality of life . Most people with hearing loss who use hearing aids say it helps their overall quality of life, relationships, work performance, general ability to communicate, and ability to participate in group activities. BHI research also shows that many say it has a positive impact on their social lives and how they feel about themselves as well as their emotional and physical health.
- The latest hearing aid technologies are better than ever and help people lead active, engaged lives. Today’s hearing aids make it easier to hear sounds and people from all directions and filter out noise. Many sit discreetly and comfortably inside the ear canal and out of sight; and many are wireless, so they can interface easily with other high-tech devices like smartphones, conference-room speakerphones, and hearing loops. Some are even waterproof, and others are rechargeable. The bottom line? As many as 91 percent of owners of the newest hearing aids—those purchased in the last year—are satisfied with their hearing aids, and 90 percent of people who purchased their hearing aid in the last four years say they’d recommend a hearing aid to a friend or family member, according to BHI research.
