Fréquence du syndrome d’apnées obstructives du sommeil en consultation externe du Centre Hospitalier Intercommunal Alençon-Mamers Frequency of obstructive sleep apnea syndrome in outpatients at Intercommunal Alençon-Mamers Hospital

Abstract

Context and objective. Obstructive sleep apneasyndrome (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.

Contexte et objectif. Le syndrome d’apnées obstructives du sommeil est une affection courante en milieu cardiologique. L’objectif de cette étude était de déterminer la fréquence et de décrire les caractéristiques du syndrome d’apnées obstructives du sommeil chez les patients vus en consultation externe. Méthodes. Il s’agit d’une étude transversale, descriptive sur une période de six mois (du 1^er juillet 2019 au 31 décembre 2019). L’étude a porté sur les patients vus en consultation externe avec une forte probabilité clinique d’un syndrome d’apnées obstructives du sommeil et confirmé par la polygraphie ventilatoire nocturne. Résultats. 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 central obstructive apnea syndrome, 39 patients (63.9%) an OSAS whereas a mixed type of syndrome was found in 3 patients (4.9%). Conclusion. Le syndrome d’apnées obstructives du sommeil est présent dans nos pratiques quotidiennes. L’accent doit être mis sur la recherche de ses symptômes afin de faire un diagnostic précoce et orienter rapidement la prise en charge.
