NPPB and coronary stenosis: In patients with acute coronary syndrome, NT‐proBNP is associated with the severity of coronary artery stenosis.34 In patients with stable angina, NT‐proBNP can predict the extent of CAD.11 Even in patients with normal left ventricular function suspected for CAD, NT‐proBNP is also an independent biomarker predicting significant coronary stenosis.12 Consistent with their findings, we observed positive predictive value of NT‐proBNP.
