Abstract

BACKGROUND: There is debate whether the J-curve relationship between cardiac event risk and DBP is because of inherent cardiac risk or is a consequence of blood pressure (BP) lowering therapy. METHODS: We examined the association between the cardiovascular risk marker amino-terminal-pro-B-type natriuretic peptide (NT-proBNP) and DBP in 1781 women and 2211 men aged at least 60 years with one or more cardiovascular risk factors; exclusion criteria were known heart failure or cardiac abnormality on a cardiac imaging study. RESULTS: The lowest median serum NT-proBNP levels were for DBP 85-89 mmHg for both women and men. DBP less than 70 mmHg in women and less than 80 mmHg in men was associated w..
