Abstract
Context and objective. Obstructive sleep apnea syndrome (OSAS) is a common condition in the cardiology setting. The objective of this study was to determine the frequency and describe the characteristics of OSAS in patients seen in the outpatient setting. Methods. This was a cross-sectional study, a descriptive analysis of data collected within 6 months from July 1st to December 31st, 2019. Based on confirmed respiratory polygraphy results, outpatients were examined and those more likely to develop OSAS were included in this study. Results. A total of 61 out of 1440 patients (4.2 %) were included. The mean age was 66.7 ± 14.5 years. Of the 61 participants, men were more likely to experience the outcome, with a sex ratio of 1.34. High blood pressure and obesity were the prevailing cardiovascular risk factors, observed among 80.3% and 77% of patients, respectively. Regarding clinical aspects, more than half (52.5 %) of study participants experienced snoring. Daytime sleepiness was present in 49.2% of patients with a mean Epworth score of 13.7 ± 0.3. Fourteen patients (23%) had minor OSAS, while 16 (26.2%) and 21 (34.4%) of the patient recordings were respectively classified with moderate and severe OSAS. Five patients (8.2%) had obstructive central apnea syndrome, it was mixed in three patients (4.9%). Conclusion. Obstructive sleep apnea syndrome is present in our daily practices. Emphasis must be placed on the search for its symptoms in order to make an early diagnosis and rapidly orientate the management. Received: December 29th, 2021 Accepted: June 21st, 2021
