title: Association of N-terminal pro-B-type natriuretic peptide with left ventricular structure and function in chronic kidney disease (from the Chronic Renal Insufficiency Cohort [CRIC]).
abstract: 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' 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 dysfunction (odds ratio 2.7, 95% CI 1.7 to 4.5) and a twofold odds of diastolic dysfunction (odds 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 dysfunction (area under the curve 0.62) and poorly for the detection of diastolic dysfunction (area under the curve 0.51). However, when added to the clinical model, NT-proBNP significantly reclassified participants' likelihood of having LVH (net reclassification improvement 0.14, 95% CI 0.13-0.15; p <0.001) and LV systolic dysfunction (net reclassification improvement 0.28, 95% CI 0.27 to 0.30; p <0.001) but not diastolic dysfunction (net 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.
