ABSTRACT

INTRODUCTION: Positive pressure ventilation is considered first line therapy in obstructive sleep apnea syndrome however compliance is limited by various factors. We aimed to investigate possible factors influencing compliance. MATERIALS AND METHODS: One hundred and forty patients were prescribed positive pressure ventilation for obstructive sleep apnea during June 2006-June 2008. Of these patients, 77% (n= 108) were reached by telephone and a questionnaire was administered regarding factors influencing treatment compliance. Airway passage was measured with C2 vertebrae level and narrowest airway passage on lateral skull radiographs. RESULTS: The mean age was 52.2 ± 12.3 years. Seventy one percent (n= 77) of subjects obtained the prescribed device. There was no difference in sex, age, marital status, educational level, symptoms, co-morbid conditions, and social security coverage between the subjects who have received the prescribed devices and who have not (p> 0.05). No difference was detected between these two groups of patients in view of Epworth sleepiness scale (ESS) and apnea hypopnea index (AHI). Mean duration of device usage was 6.3 ± 2.3 hours. The device use compliance was not affected by any of the following factors: age, gender, level of education, co-morbid diseases, ESS score, AHI, airway passage measurements, application of humidification and education concerning the device (p> 0.05). Patient (p= 0.057) and bed partners (p= 0.001) satisfaction about the device yielded higher compliance rates. CONCLUSION: Factors influencing compliance rates in obstructive sleep apnea syndrome seems to be related to satisfaction about the device use however upper airway morphology measured with C2 vertebrae level and narrowest airway passage has no impact on treatment compliance.

ABSTRACT

OBJECTIVE: To evaluate the effect of continuous positive airway pressure (CPAP) therapy on pro-brain natriuretic peptide (BNP) and cardiac markers in patients with obstructive sleep apnea syndrome and normal cardiac function. METHODS: Thirty-three consecutive patients with sleep apnea syndrome were analysed for serum pro-BNP and cardiac markers prior to and after 6 months of CPAP therapy. RESULTS: Twenty five patients had normal (83.3%) while remaining five (16.7%) revealed high pro-BNP values. We did not detect any significant difference between severity of obstructive sleep apnea syndrome and serum pro-BNP levels (p = 0.534). A statistically significant difference was not observed between basal and sixth-month creatine kinase (CK), creatine kinase-MB (CK-MB), troponin I, pro-BNP, aspartate transaminase (AST), and CK levels in patients with sleep apnea syndrome (p > 0.05). CONCLUSION: Obstructive sleep apnea syndrome does not induce myocardial damage enough to increase serum pro-BNP, CK, CK-MB, troponin I, and AST levels. Markers sensitive to ischemia could be preferred to evaluate effect of obstructive sleep apnea syndrome.
