N-Terminal Pro–B-type Natriuretic Peptide and Stroke Risk

Background and Purpose— Improved identification of those at risk of stroke might improve prevention. We evaluated the association of the cardiac function biomarker N-terminal pro–B-type natriuretic peptide (NT-proBNP) with stroke risk in the 30 239 black and white participants of the Reasons for Geographic and Racial Differences in Stroke (REGARDS) cohort.
