Comparison of the Capabilities of a Midregional Fragment of the Pro-A-Type Natriuretic Peptide and the N-Terminal Pro-B-Type Natriuretic Peptide for Predicting Mortality and Cardiovascular Events

Study Questions:

What is the comparative prognostic value for a midregional fragment of pro–A-type natriuretic peptide (MR-proANP) and N-terminal pro–B-type natriuretic peptide (NT-proBNP) for predicting mortality and cardiovascular events?
