Data were compared.Results: 36 OHS patients (23 female) with mean body mass index 45±11,age 61±13 were enrolled in the study.During 9 month among echocardiographic parameters related with right heart function significant change were found in systolic pulmonary arterial pressure,TAPSE and serum BNP levels(43±8 vs 38±8 mmhg ,p‹0.002; 2.1±0.3 cm vs 2.4±0.4 cm,p‹0.002; 1049±624 vs 358±255 pg/ml, p=0.029 respectively).However there was no significant difference in left ventricle ejection fraction and left atrial function(63 ±7 vs 64 ±7 %, p>0.11 ;3.7± 0.7 vs 3.6± 0.6 p>0.55 respectively)Conlusion: Long term NIV treatment in patients with respiratory failure due to OHS provides significant improvement in right heart failure and BNP level.
