3.1.1 Correlation with heart failure markers RA function exhibited correlations with heart failure parameters in EA patients (see Table 2 ): 1) atrial reservoir function correlated significantly with BNP level (RA εs and SRs) and NYHA class ( p < 0.05 for RA εs; and a strong trend for RA SRs, p = 0.067); 2) atrial conduit function (RA εe and SRe) correlated with the R/L-Volume Index; and 3) atrial booster pump function (RA εa and SRa) correlated with NYHA class and BNP (see Table 2 ).
