We evaluated the cross-sectional associations of N-terminal pro-B-type natriuretic peptide (NT-proBNP) with cardiac structural and functional abnormalities in a cohort of patients with chronic kidney disease without clinical heart failure, the Chronic Renal Insufficiency Cohort (n = 3,232). The associations of NT-proBNP with echocardiographically determined left ventricular (LV) mass and LV systolic and diastolic function were evaluated using multivariate logistic and linear regression models. Reclassification of participants%26apos; predicted risk of LV hypertrophy (LVH), systolic and diastolic dysfunction was performed using a category-free net reclassification improvement index that compared a clinical model with and without NT-proBNP. The median NT-proBNP was 126.6 pg/ml (interquartile range 55.5 to 303.7). The greatest quartile of NT-proBNP was associated with a nearly threefold odds of LVH (odds ratio 2.7, 95% confidence interval [CI] 1.8 to 4.0) and LV systolic dysodds ratio 2.7, 95% CI 1.7 to 4.5) and a twofold odds of diastolic dysodds ratio 2.0, 95% CI 1.3 to 2.9) in the fully adjusted models. When evaluated alone as a screening test, NT-proBNP functioned modestly for the detection of LVH (area under the curve 0.66) and LV systolic dysarea under the curve 0.62) and poorly for the detection of diastolic dysarea under the curve 0.51). However, when added to the clinical model, NT-proBNP significantly reclassified participants%26apos; likelihood of having LVH (net reclassification improvement 0.14, 95% CI 0.13-0.15; p %26lt; 0.001) and LV systolic dysnet reclassification improvement 0.28, 95% CI 0.27 to 0.30; p %26lt; 0.001) but not diastolic dysnet reclassification improvement 0.10, 95% CI 0.10 to 0.11; p = 0.07). In conclusion, in this large chronic kidney disease cohort without heart failure, NT-proBNP had strong associations with prevalent LVH and LV systolic dysfunction.
