There was a statistically significant, strong positive correlation between the number of B-lines and the NT-proBNP plasma concentration (rs(77) = 0.628, p < 0.001) and a positive correlation with the NYHA class (rs(107) = 0.301, p = 0.002) and hypoalbuminemia (rs(107) = −0.194, p = 0.046). This evidence concerns the gene NPPB and Hypoalbuminemia.
