To the best of my knowledge, there is no study showing long term effects of chronic NIV use in COPD patients. However, there is one study (open access) for the whole group of patients with chronic respiratory failure:
Thorax. 2001 Jul;56(7):524-8.
Long term effects of non-invasive mechanical ventilation on pulmonary haemodynamics in patients with chronic respiratory failure.
Schönhofer B, Barchfeld T, Wenzel M, Köhler D.
Schönhofer et al. could show that one year of NIV use in patients with restrictive thoracic disorders improved PA pressure and PVR. However, in COPD no changes were observed regarding pulmonary hemodynamics. It has to be mentioned that in this study the restrictive group had a higher PA pressure (32 mm Hg) than the COPD group (25 mm Hg) which may explain the lack in change.
The absence of prove does not mean the absence of an effect.
