Cardiovascular disease
The cochlea is fed by a single tiny artery with no backup supply. The same vessel damage behind heart disease can starve the inner ear, so hearing changes may be an early sign of cardiovascular trouble.
Reduced blood flow to the stria vascularis and the hair cells of the cochlea.
People with hearing loss had 1.38 times the odds of cardiovascular disease, and 1.36 times the odds of coronary artery disease, across about 1.6 million people.
