Abstract
Introduction: Obstructive Sleep apnea-hypopnea syndrome (OSAHS) is defined by the repetitive occurrence of brief apneas during sleep. The best treatment remains the Continuous Positive Airway Pressure (CPAP). The Objective of our study was to evaluate the efficacity of the CPAP in the improvement of the sub-maximal exercise capacity in obese patients with (OSAHS).
Patients and Methods: 31 obese patients with OSAHS were included. We did a plethysmography and a 6-MWT for every patient. We specified anthropometric data and Clinical symptoms.
Results: Our population was divided into 2 groups: patients treated by the CPAP G1 (n=18) and patients not treated G2 (n=13). The sex-ratio, body mass index and the average age were similar in both groups. We didn’t find a significant difference in daytime sleepiness, night snoring, exercise dyspnea and chronic cough. There was no difference between the 2 groupes regarding the forced expiratory volume in 1s, the FEV1 / FVC and the lung residual volume. The 6MWT profile was as follows: 11% of patients in G1 had a dyspnea at the end of the test vs 23% in G2; 16.7% of the patients in G1 had a chronotropic insufficiency vs 15% in G2. We didn’t find a difference regarding the walking distance or the desaturation during the test.
Conclusion and Discussion: Our study shows that the treatment by CPAP in obese patients with severe OSAHS doesn’t improve the function of the muscular and cardiorespiratory chain. In addition to CPAP, a pulmonary rehabilitation program training and weight reduction can help us in the care of those patients.
