Abstract

Natriuretic peptides (NP) are cardiac-derived hormones with favorable cardiometabolic actions. Low NP levels are associated with increased risks of hypertension and diabetes mellitus, conditions with variable prevalence by race and ethnicity. Heritable factors underlie a significant proportion of the interindividual variation in NP concentrations, but the specific influences of race and ancestry are unknown. In 5597 individuals (40% white, 24% black, 23% Hispanic, and 13% Chinese) without prevalent cardiovascular disease at baseline in the Multi-Ethnic Study of Atherosclerosis, multivariable linear regression and restricted cubic splines were used to estimate differences in serum N-terminal pro B-type natriuretic peptide (NT-proBNP) levels according to, ethnicity, and ancestry. Ancestry was determined using genetic ancestry informative markers. NT-proBNP concentrations differed significantly by race and ethnicity (black, median 43 pg/ml [interquartile range 17 to 94], Chinese 43 [17 to 90], Hispanic 53 [23 to 107], white 68 [34 to 136]; p = 0.0001). In multivariable models, NT-proBNP was 44% lower (95% confidence interval −48 to −40) in black and 46% lower (−50 to −41) in Chinese, compared with white individuals. Hispanic individuals had intermediate concentrations. Self-identified blacks and Hispanics were the most genetically admixed. Among self-identified black individuals, a 20% increase in genetic European ancestry was associated with 12% higher (1% to 23%) NT-proBNP. Among Hispanic individuals, genetic European and African ancestry were positively and negatively associated with NT-proBNP levels, respectively. In conclusion, NT-proBNP levels differ according to race and ethnicity, with the lowest concentrations in black and Chinese individuals. Racial and ethnic differences in NT-proBNP may have a genetic basis, with European and African ancestry associated with higher and lower NT-proBNP concentrations, respectively.
