OBJECTIVES: This study sought to investigate plasma levels of circulating cardiac
natriuretic peptides, atrial natriuretic peptide (ANP) and B-type or brain
natriuretic peptide (BNP), in the general community, focusing on their relative
differences in worsening human hypertension. BACKGROUND: Although ANP and BNP are
well-characterized regulators of blood pressure in humans, little is known at the
population level about their relationship with hypertension. The authors
hypothesized that hypertension is associated with a lack of activation of these
hormones or their molecular precursors. METHODS: The study cohort (N = 2,082, age
>45 years) was derived from a random sample from Rochester, Minnesota, and each
subject had a medical history, clinical examination, and assessment of different
plasma forms of ANP and BNP. Patients were stratified by blood pressure.
Multivariable linear regression was used to assess differences in natriuretic
peptide levels in worsening hypertension. RESULTS: Compared to normotensive,
BNP(1-32) and N-terminal proBNP(1-76) (NT-proBNP(1-76)) were significantly
decreased in pre-hypertension (p < 0.05), with BNP(1-32) significantly decreased
in stage 1 as well (p < 0.05). Although proBNP(1-108) remained unchanged, the
processed form was significantly increased only in stage 2 hypertension (p <
0.05). ANP(1-28) remained unchanged, while NT-ANP(1-98) was reduced in
pre-hypertension (p < 0.05). CONCLUSIONS: The authors demonstrated the existence
of an impaired production and/or release of proBNP(1-108) along with a
concomitant reduction of BNP(1-32) and NT-proBNP(1-76) in the early stages of
hypertension, with a significant elevation only in stage 2 hypertension.
Importantly, they simultaneously demonstrated a lack of compensatory ANP
elevation in advanced hypertension.
