Levels of B-type natriuretic peptide (BNP) at presentation to the Emergency Department in all patients according to the adjudicated final diagnosis. Boxes represent interquartile ranges (IQRs), while whiskers display ranges (without outliers further than 1.5 IQRs from the end of the box). CAD=coronary artery disease.

Diagnostic and prognostic performance of troponin T and B-type natriuretic peptide (BNP) in receiver operating characteristic (ROC) curve analysis. ROC curves describing (A) the diagnostic performance of troponin T and BNP at presentation in the diagnosis of acute myocardial infarction and (B) the prognostic performance of troponin T and BNP in determining all-cause mortality.

Kaplan-Meier curves for (A) survival in all chest pain patients and (B) survival free of acute myocardial infarction in nonacute myocardial infarction patients. (A) Kaplan-Meier analysis displaying cumulative survival during follow-up in all chest pain patients (n=1075) subdivided into B-type natriuretic peptide (BNP) quartiles. (B) Kaplan-Meier analysis of patients without acute myocardial infarction at presentation (n=907) displaying the combined endpoint of survival free of acute myocardial infarction during follow-up according to BNP quartiles.

B-type natriuretic peptide (BNP) levels in patients without myocardial infarction at presentation according to different risk categories. BNP levels in patients without myocardial infarction at presentation according to events (death and nonfatal myocardial infarction) during follow-up and according to different risk categories. Risk categories are based on history, physical examination, initial 12-lead electrocardiogram, and troponin T as proposed in the American College of Cardiology/American Heart Association (ACC/AHA) 2007 guidelines for the management of patients with unstable angina/non-ST-elevation myocardial infarction.25 Event rates in the high- (n=246), intermediate- (n=332), and low-risk categories (n=329) were 10%, 4%, and 2%, respectively.
