There is conclusive evidence that @entity27 ( @entity27 ) influences right heart haemodynamics and can also induce @entity120 . It is not known, however, whether @entity67 can occur in @entity1 with @entity27 in the @entity358 . We studied 107 @entity1 (94 males, 13 females, mean age 55 +/- 11 yrs) with polysomnographically verified @entity27 in whom clinically significant @entity358 was excluded. @entity4266 ( @entity4266 ) was determined by radionuclide ventriculography. In addition, pulmonary function tests, arterial blood gas analysis and right heart catheterization were performed. @entity4266 was impaired in 19 @entity1 (18%). Eighteen (95%) had signs or symptoms consistent with mild @entity67 . @entity1 with or without impaired @entity4266 did not differ with respect to body mass index, age or lung function. Stepwise multiple logistic regression analysis revealed that @entity4266 was significantly associated with the apnoea/hypopnoea index (r = -0.68; p = 0.0009) and the extent of nocturnal @entity7672 saturation (r = 0.42; p = 0.035), but not with age, body mass index, blood gas analysis, gender, lung function, pulmonary artery pressure and left ventricular ejection fraction. We conclude that in @entity1 with otherwise unexplained @entity67 , @entity27 may underlie the @entity67 .

Right @entity67 in XXXX with @entity27 .
