Cardiovascular biomarkers and subclinical brain disease in the atherosclerosis risk in communities study.

ABSTRACT:

Background and purpose

Cerebrovascular and cardiovascular disease share common risk factors. Our goal was to determine whether levels of N-terminal brain natriuretic peptide (NT-proBNP) and cardiac troponin T measured with a highly sensitive assay (hs-cTnT) are associated with silent brain infarcts (BIs) and white matter lesions (WMLs) on MRI in the Atherosclerosis Risk in Communities (ARIC) study.

Methods

At ARIC visit 3 (1993-1995), 1920 participants had brain MRI. NT-proBNP and hs-cTnT were measured in all individuals at ARIC visit 4 (1996-1998). Of 1920 individuals, 1112 had a follow-up MRI [2004-2006]). We analyzed the association of NT-proBNP and hs-cTnT with MRI-defined BI and WML on the initial MRI and incident BI and WML progression on the follow-up MRI in participa
