However, there is little information on the association between BNP and invasive haemodynamics in AS. The aim of the present study was to assess the hitherto not well-defined relationship between BNP and invasive haemodynamics in patients with severe AS undergoing aortic valve replacement (AVR) with a view to understand the link between high BNP and poor prognosis in these patients. In particular, we were interested in the association between BNP and combined pre-capillary and post-capillary pulmonary hypertension (CpcPH).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>BNP was measured in 252 patients (age 74 \u00b1 10 years, 58% male patients) with severe AS [indexed aortic valve area 0.4 \u00b1 0.1 cm2\/m2 and left ventricular ejection fraction (LVEF) 57 \u00b1 12%] the day before cardiac catheterization. Patients were followed for a median (interquartile range) period of 3.1 (2.3\u20134.3) years after surgical (n = 157) or transcatheter (n = 95) AVR. The prevalence of CpcPH (mean pulmonary artery pressure \u2265 25 mmHg, mean pulmonary artery wedge pressure &amp;gt; 15 mmHg, and pulmonary vascular resistance &amp;gt; 3 Wood units) was 13%. The median BNP plasma concentration was 188 (78\u2013452) ng\/L. The indexed aortic valve area was similar across BNP quartiles (P = 0.21). Independent predictors of higher BNP (ln transformed) included lower haemoglobin (beta = \u22120.18; P &amp;lt; 0.001), lower LVEF (beta = \u22120.20; P &amp;lt; 0.001), more severe mitral regurgitation (beta = 0.20; P &amp;lt; 0.001), higher mean pulmonary artery wedge pressure (beta = \u22120.37; P &amp;lt; 0.001), and higher pulmonary vascular resistance (beta = 0.21; P &amp;lt; 0.001). In a multivariate model with CpcPH rather than its haemodynamic components, CpcPH was independently associated with higher BNP (0.21; P &amp;lt; 0.001). Higher ln BNP was associated with higher mortality [hazard ratio 1.90 (95% confidence interval 1.33\u20132.71); P &amp;lt; 0.001] in the univariate analysis. Patients in the third and fourth BNP quartiles had a more than six-fold risk of death compared with patients in the first and second quartiles [hazard ratio 6.29 (95% confidence interval 1.86\u201321.27); P = 0.003]. In the multivariate analysis, lower LVEF [hazard ratio 0.96 (95% confidence interval 0.94\u20130.99) per 1% increase; P = 0.01] and CpcPH [hazard ratio 4.58 (95% confidence interval 1.89\u201311.09); P = 0.001] but not BNP were independently associated with mortality. The areas under the receiver operator characteristics curve for BNP for the prediction of CpcPH and mortality were 0.88 and 0.74, respectively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In patients with severe AS, higher BNP is a marker of the presence of CpcPH and its contributors.
