NPPB and cardiomyopathy: A multivariable analysis of the predictors of cardiomyopathy in a cohort of 246 prevalent hemodialysis and peritoneal dialysis patients found that log-transformed serum BNP concentration was a significant predictor of LV ejection fraction (β = −0.48, p < 0.0001) and LV mass indexed to height (β = 0.36, p < 0.0001) after adjusting for blood pressure, age, diabetes, albumin, hemoglobin, treatment modality, small molecule clearance, and time on renal replacement therapy [68].
