Hemodynamic effects of noninvasive bilevel positive airway pressure on patients with chronic congestive heart failure with systolic dysfunction.

abstract：BACKGROUND:N-terminal pro-brain natriuretic peptide (NT-proBNP) is a byproduct of the brain natriuretic peptide (BNP) that was shown to be of prognostic value in pulmonary hypertension (PH). The role of NT-proBNP in PH has to be determined, especially under the influence of renal impairment that might lead to an accumu...
