Influence of nocturnal hypoxemia on follow-up course after type B acute aortic syndrome.

Introduction: Association between sleep nocturnal breathing disorders and acute aortic syndrome (AAS) has been described but mid-term data are scarce.

Objectives: We assessed the prognostic value of sleep apnea parameters and their relationship with aortic morphology after the onset of a type B AAS.

Methods: Between January 2010 and January 2018, sleep apnea screening in post type B AAS was prospectively performed.
