Key result
Plasma concentrations of immunoreactive atrial natriuretic peptide positively correlated with mean pulmonary artery pressure (r=0.70, p<0.01) and pulmonary vascular resistance (r=0.88, p<0.001).
Why the study?

Adnot et al. (1987) conducted a cross-sectional in chronic pulmonary artery hypertension (n=15). Plasma immunoreactive atrial natriuretic peptide (IR-ANP) levels was evaluated on Correlation between plasma IR-ANP and mean pulmonary artery pressure at rest (r = 0.70, p=<0.01). Plasma concentrations of immunoreactive atrial natriuretic peptide positively correlated with mean pulmonary artery pressure (r=0.70, p<0.01) and pulmonary vascular resistance (r=0.88, p<0.001).
