A Link Between Hearing Loss and Heart Health

A Link Between Hearing Loss and Heart Health

Dr. Li-Korotky

When your body performs correctly, it’s like a well-oiled machine. Each part contributes to the overall well-being of an individual and when one part mis-fires, there can be a cascading effect. In the same way you get your physical, your vision checked, and practice good dental care, you should also be getting routine hearing exams at Pacific Northwest Audiology. Hearing healthcare is an important part of your overall health and well-being, though it is often overlooked because hearing is an “invisible” sense. In fact, hearing is related to many parts of your physical health – including your cardiovascular system.

Heart Disease and Mortality

Statistics from the Centers for Disease Control indicate heart disease is the leading cause of death for both men and women with nearly 610,000 dying each year in the United States. Those with cardiovascular disease have a variety of different medical issues that affect the vessels and structure of the heart. The most common problem involves the narrowing or blocking of vessels which leads to chest pains, a heart attack or stroke. Other cardiovascular problems affect the heart’s muscles, valves or rhythm.

“Cardiovascular disease robs the life of about one American every minute, and heart disease is the No. 1 killer of women,” according to Sergei Kochkin, hearing industry researcher and former executive director of the Better Hearing Institute. “Yet, an alarming number of Americans don’t understand how serious the threat of heart disease is to them personally, or how closely intertwined it is without health conditions such as hearing health,” Kochkin added. “We urge women and men alike to know their risks and to take action today to protect their heart and hearing health.”

It’s All About Blood Flow

The connection between heart health and hearing loss involves blood flow. Studies show proper circulation plays a key role in maintaining good hearing health. Inadequate blood flow and trauma to the blood vessels in the inner ear contribute to hearing loss. Why? Because the tiny oh-so delicate hair cells in the cochlea or inner ear play a very important role in processing the “noise” your ears collect into electrical impulses that your brain translates into “sound.” Poor circulation deprives the hair cells of oxygen and the oxygen starved cells are damaged or destroyed. These do not regenerate and could lead to permanent hearing loss.

A study published in the June 2010 issue of the American Journal of Audiology reviewed research conducted over the past 60 years on cardiovascular health and its influence on hearing health. The study authors Raymond Hull and Stacy Kerschen concluded that impaired cardiovascular health negatively affects both the peripheral and central auditory system, especially in seniors.

Get Moving – It Helps!
Although sensorineural hearing loss – that’s hearing loss due to damaged hair cells – is permanent, you can protect your hearing by increasing your blood flow with exercise. Clear it with your physician, of course, but a fitness program that includes cardiovascular exercise is a great idea!

Researchers have discovered a positive link between hearing sharpness and cardiovascular exercise. The study tracked 102 non-smoking volunteers aged 22 to 78. Their hearing was evaluated after they rode a stationery bike. They concluded those with higher cardiovascular fitness levels maintained better hearing, especially in the age group of 50 and older.
Charles Bishop, a professor with the University of Mississippi Medical Center, says Americans should take heart disease seriously. It’s a disease with life-threatening effects that impacts all areas of life including hearing health. “Hearing health should not be assessed in a vacuum,” Bishop said. “There is simply too much evidence that hearing loss is related to cardiovascular disease and other health conditions. It’s time we maximized the information we have in order to benefit the individual’s overall well-being.”
