Key result
NT-proBNP demonstrated superior diagnostic accuracy for mildly/moderately reduced LVEF (AUC 0.927 vs 0.843, p=0.034), while BNP had fewer misclassifications for severely impaired LVEF (p<0.001).
Why the study?
Does BNP or NT-proBNP provide better diagnostic accuracy for detecting mildly/moderately or severely impaired LVEF in subjects undergoing echocardiography?
Cross-Sectional (n=180)
Does BNP or NT-proBNP provide better diagnostic accuracy for detecting mildly/moderately or severely impaired LVEF in subjects undergoing echocardiography?
Effect estimate: Difference 0.016
Absolute Event Rate: 0.912% vs 0.896%
p-value: p=0.554
BNP may be more accurate for diagnosing severely impaired LVEF (<35%), while NT-proBNP is more accurate for detecting mildly/moderately reduced LVEF (35-60%).

May support biomarker selection by suspected LVEF severity; hypothesis-generating and should not yet change practice.
Mueller et al. (2004) conducted a cross-sectional in Impaired left ventricular ejection fraction (n=180). BNP vs. NT-proBNP was evaluated on Diagnostic accuracy (AUC) for detecting LVEF < 35% (Difference 0.016, p=0.554). NT-proBNP demonstrated superior diagnostic accuracy for mildly/moderately reduced LVEF (AUC 0.927 vs 0.843, p=0.034), while BNP had fewer misclassifications for severely impaired LVEF (p<0.001).
