Associations of circulating natriuretic peptides with haemodynamics in precapillary pulmonary hypertension

MR-proANP demonstrated equivalent associations with haemodynamics compared to NT-proBNP, but both markers depend on intact renal function. NT-proCNP was correlated with RAP and renal function, while DNP showed no associations. Larger studies should evaluate MR-proANP as candidate prognostic biomarker in PH.
