N2 - PURPOSE: We aimed to evaluate the three hypopnea criteria, A and B from 2007 and the revised from 2012, proposed by the American Academy of Sleep Medicine (AASM) for scoring sleep-related breathing disorders (SRBDs) in patients with acute stroke or transient ischemic attack (TIA).METHODS: Polysomnographies (PSGs) in patients with TIA or stroke were scored according to the A-, B-, and 2012-hypopnea criteria.RESULTS: Sixty-three PSGs were eligible for hypopnea scoring. There was no difference in the number of patients diagnosed with the B- and 2012-criteria. Therefore, they are mentioned as one. Forty-seven patients (75 %) were diagnosed with SRBD using the A-criteria versus 57 patients (90 %) using the B/2012-criteria (p < 0.0016). In 30 cases, a change from A- to B/2012-criteria resulted in a change in diagnosis. Ten cases of "no SRBD" changed to mild/moderate/severe SRBD. An apnea hypopnea index (AHI) >15 is a typical indication of treatment. With the B/2012-criteria, we found an additional indication of treatment in 18 patients, compared to when the A-criteria were applied (p < 0.0001). Two of these patients were labeled as no SRBD with the A-criteria.CONCLUSION: The difference is significant between the AHIs achieved by the A- and the B-/2012-hypopnea criteria, with much lower AHIs achieved with the A-criteria. As SRBD treatment lessens the risk of complications, correct identification of SRBD patients is of the utmost importance.
