A new study shows evidence of the correlation between heart failure and hearing loss among older adults in the United States. Researchers from Weill Cornell Medical College in New York City used data from the 2005-2006 and 2009-2010 National Health and Nutrition Examination Survey examined the prevalence and correlation of hearing loss among the elderly with or without heart conditions.
Study authors Madeline R. Sterling, MD, MPH, Frank R. Lin, MD, PhD, Deanna P. Jannat-Khah, DrPH, MSPH, Adele M. Goman, PhD, Sandra E. Echeverria, PhD, and Monika M. Safford, in a research letter, wrote that "Hearing loss is common among older adults in the United States and is associated with coronary heart disease and its risk factors. Yet, the prevalence of hearing loss among adults with heart failure (HF) has not been well described."
The study, titled Hearing Loss Among Older Adults with Heart Failure in the United States, revealed that the participants with heart failure were older, with more existing cardiovascular medical conditions, and had a higher disposition to hearing loss compared with those participants without heart failure. The researchers looked into the survey data of adults aged 70 and older and found out that hearing loss among those with heart failure was more common at 74.4 percent compared with the 63.3 percent among those without coronary comorbidity. Results of the examination also showed that participants with heart failure are more likely susceptible to varying degrees of hearing loss.
"Although hearing loss was more common among adults with HF compared with those without it, HF was not independently associated with hearing loss after accounting for demographic and clinical characteristics," the research authors explained.
The researchers said that further studies on heart failure-hearing loss link among the elder population in the United States may provide more information. "Future studies might examine potential correlates of hearing loss that we were unable to study, including ejection fraction and HF-specific medications like furosemide, which has ototoxic properties."
