Abstract: Objective To investigate the accuracy of Berlin Questionnaire in patients with pulmonary embolism (PE).Methods We retrospectively compared the results of Berlin Questionnaire and sleep study for 101 and 66 subjects with and without PE.Results Totally, 74 (73.3%) PE and 46 (69.7%) non-PE patients were diagnosed as obstructive sleep apnea (OSA) by sleep study. Patients with PE demonstrated low accuracy of Berlin Questionnaire assessment, with sensitivity, specificity, positive predictive value, and negative predictive value of 70.3%, 48.1%, 78.8% and 37.1%, respectively. Among subjects objectively diagnosed of OSA, fewer PE patients complained of sleepiness than non-PE counterparts[27(36.5%) vs 26(56.5%), P=0.032]. OSA patients complicated with PE had lower Epworth Scale Score than those without PE(8.6 vs 10.3,P=0.023).Conclusion Berlin Questionnaire yields poorly to diagnose OSA in patients with PE, which may be related to low prevalence of sleepiness in this group. Objective sleep study is indicated for PE patients suspicious of sleep disordered breathing.
