Abstract：Objective To explore the effects of Tei index on bi level positive airway pressure for treatment of coronary heart disease (CHD)patients with sleep disordered breathing (SDB).Methods Sixty patients tested with PSG were al ocated to central SDB group,obstructive SDB group and blend SDB group(20 cases per group).Al patients were tested with right heart function(Tei index)with 2D echo,vascular endothelial function(ET 1 and NO)and PSG index(AHI,LSaO2 ,the time of SaO2<90%).These measurements were repeated in patients one month later after BiPAP treatment and one month.Results The PSG index,right heart function and vascular endothelial function were significantly improved after BiPAP treatment in three groups.Conclusion BiPAP can improve hypoxia and vascular endothelial function,enhance right heart function and therefore may be useful in treatment of CHD with SDB.
