Objective: Both Obstructive sleep apnea (OSA) and coronary slow-flow (CSF) have similar pathogenic mechanisms, such as chronic sympathetic activation, upregulation of inflammatory pathways. However, importance true coincidence and of CSF and OSA is not known very well. In this study, we examined the presence of OSA by using questionnaire, including Berlin questionnaire (BQ), STOP-Bang questionnaire, and Epworth (ESS) in the patients diagnosed CSF after coronary angiography. Material and methods: This prospective study included 4515 patients admitted angiography laboratory. Of the patients, 336 patients were diagnosed CSF in coronary angiography. Control group patients (n=40) had normal coronary artery, which was no slow coronary flow, no OSA. The patients with CSF were asked with sleep questionnaire. Results: Of 4515 patients, 336 (7.4 %) met the criteria for CSF. After sleep questionnaire, BQ scores were 276/336 in patients (82.1%). ESS scores of 11-24 were 134/336 in patients (39.8%). Of 336 patients, 254 patients were ? 3 scores for STOP -Bang questionnaire (75.59%). Conclusion: We demonstrated association with coronary CSF and OSA via the usage of questionnaire. However, more large studies require to evaluate the relationship between OSA and CSF. Keywords: Coronary slow flow; Obstructive sleep apnea; Sleep questionnaire
