Abstract
BACKGROUND: Neurotensin, a neuropeptide with direct cardiac effects, has been associated with prospective risk of hypertension-related conditions through measurement of its precursor, pro-neurotensin/neuromedin N (pro-NT/NMN). Its association with incident hypertension has not been evaluated. METHODS: From 2003 to 2007, the REasons for Geographic And Racial Differences in Stroke (REGARDS) study enrolled 30,239 Black or White adults age ≥45. Pro-NT/NMN was measured in 1,692 participants without baseline hypertension (self-reported antihypertensive use or blood pressure ≥140/90 mm Hg) who underwent follow-up assessment in 2013-2016. A sensitivity analysis was conducted using a lower threshold (≥130/80 mm Hg) to define hypertension. Three robust Poisson regression models were fitted to risk of incident hypertension, adding demographics, cardiometabolic risk factors, and dietary covariates. RESULTS: Six hundred and fourteen participants developed hypertension over 9.4 years of follow-up. Pro-NT/NMN ranged from 14 to 1,246 pmol/l, with median [interquartile range] 154 [112, 206] pmol/l. Pro-NT/NMN was not associated with hypertension overall (fully adjusted incidence rate ratio per SD increment log pro-NT/NMN 1.03, 95% confidence interval 0.95-1.11). Results of sensitivity analysis did not differ substantially. CONCLUSIONS: Baseline pro-NT/NMN was not associated with incident hypertension. This may be a result of neurotensin's long-term interactions with other molecular regulators of blood pressure, such as the renin-angiotensin-aldosterone system. © American Journal of Hypertension, Ltd 2021.
