BOSTON – In a study of patients without a previous diagnosis of obstructive sleep apnea (OSA), 85% of participants in outpatient arrhythmia clinics had undetected OSA.
The study, which also excluded patients who had ever been treated for OSA, was presented by Colin Shapiro, MD, of the Department of Psychiatry, Toronto Western Hospital, University of Toronto, at the annual meeting of the Associated Professional Sleep Societies.
A binary logistic regression analysis showed that only age and male gender were significant predictors of OSA.
Along with a home sleep study, researchers tested 75 nonselected consecutive patients (mean age of 64 years; 72% male) from three outpatient arrhythmia clinics for symptoms indicative of OSA using the Epworth Sleepiness Scale (ESS), the Fatigue Severity Scale (FSS), the Non-Restorative Sleep Scale (NRSS), and other questionnaires.
On the ESS, 32% of patients had a score of 8 or greater, indicating higher than normal daytime sleepiness. Almost half (47%) of patients had a high level of fatigue on the FSS, and symptoms of nonrestorative sleep were detected in 15% (NRSS score greater than or equal to 46).
Dr. Shapiro noted that “high scores suggestive of daytime sleepiness, fatigue, or insomnia did not particularly predict the presence of OSA in patients with arrhythmia.” He concluded that, “with a hit rate of 85%, just about every patient with an arrhythmia should have a sleep study.”
Dr. Shapiro informed attendees at the annual meeting of the Professional Sleep Societies that he was presenting in place of his student and the abstract’s first author, Dr. Asmaa M. Abumuamar, MD, who was denied a visa to attend the meeting. Dr. Abumuamar is from the Toronto Western Research Institute, University of Toronto.
Dr. Shapiro reported that Dr. Abumuamar has no conflicts of interest. Dr. Shapiro reported that he is an investor in the company that supplied the home sleep testing apparatus.

AT SLEEP 2017
Key clinical point: The majority of patients attending an outpatient arrhythmia clinic had undetected OSA.
Major finding: Of the participants, 91% of males and 71% of females with no history of OSA were found to have the disorder (85% of total).
Data source: A screening study using a randomized, unselected population drawn from outpatient arrhythmia clinics. Those with a diagnoses of OSA were excluded.
Disclosures: Dr. Shapiro reported that Dr. Abumuamar has no conflicts of interest. Dr. Shapiro reported that he is an investor in the company that supplied the home sleep testing apparatus.
