A new research says women who suffer from obstructive sleep apnea (OSA), as well as snoring, may be at a greater risk of impairment of cardiac function than men. Snoring may be a sign of OSA, which is a serious sleep disorder in which breathing repeatedly stops and starts.
While there are several symptoms of OSA including gasping for air during sleep, morning headache and irritability, waking with a dry mouth, loud snoring is a common sign.
In a study presented at the annual meeting of the Radiological Society of North America (RSNA), researchers looked at data from 4,877 UK Biobank participants all of whom had cardiac MRIs and put them into three groups based on their OSA status: those who knowingly have the disorder, those who snore, and those who have neither issue.
They found that the women with obstructive sleep apnea (OSA) or those who had it but were undiagnosed could experience the impaired function of the heart earlier. That’s because sleep disorder increases the risk of left or right ventricular dysfunction, both of which can result in heart failure.
“We found that the cardiac parameters in women appear to be more easily affected by the disease and that women who snore or have OSA might be at greater risk for cardiac involvement,” said lead study author Adrian Curta, MD, in a press release. “We also found that the prevalence of diagnosed OSA in the study group was extremely low. Together with the alterations in cardiac function in the snoring group, it leads us to believe that OSA may be grossly under-diagnosed.”
Dr Curta says, “This study is an eye-opener for snorers to get screened for the disorder—and get the proper treatment if they do.”
“I would encourage people who snore to ask their partner to observe them and look for phases during sleep when they stop breathing for a short while and then gasp for air,” she said. “If they’re unsure, they can spend the night at a sleep lab where breathing is constantly monitored during sleep and even slight alterations can be recorded.”
Curta further said, “The prevalence of diagnosed OSA in the study group was extremely low. Together with the alterations in cardiac function in the snoring group, it leads us to believe that OSA may be grossly underdiagnosed.”
Treatment is dependent on the cause of an individual’s OSA. For instance, weight loss can often improve OSA in overweight individuals.
