High-Sensitivity Troponin I and Amino-Terminal Pro-B–Type Natriuretic Peptide Predict Heart Failure and Mortality in the General Population

Study Questions:

What is the prognostic utility of a novel cardiac troponin I (cTnI) high-sensitivity assay, independently and in combination with amino-terminal pro–B-type natriuretic peptide (NT-proBNP), to predict development of heart failure (HF) in the future and mortality in the general population?
