Assessment of risk reclassification from magnetic resonance determined LV mass index (LVMI) vs log NT-proBNP using net reclassification method in MESA

Models c-Statistic NRI (p value)
Model 1 0.80
Model 1+LVMI 0.85 0.25 (<0.001)
Model 1+ log NT-proBNP 0.87 0.37 (<0.001)
(Model 1, LVMI)+ log NT-proBNP 0.89 0.15 (0.018)*
(Model 1, log NT proBNP)+LVMI 0.89 0.01 (0.911)*

Model 1: age, ethnicity, gender, BMI, cigarette smoking, systolic blood pressure, heart rate, diabetes mellitus, total cholesterol and HDL cholesterol.

*

For HF risk categories <5%, 5–20% and >20%.

HF, heart failure; MESA, Multi-Ethnic Study of Atherosclerosis; NRI, net reclassification improvement; NT-proBNP, N-terminal pro-B-type natriuretic peptide.
