Race-based demographic, anthropometric and clinical correlates of N-terminal-pro B-type natriuretic peptide.

ABSTRACT: BACKGROUND:Population studies have shown that black race is a natriuretic peptide (NP) deficiency state. We sought to assess whether the effects of age, sex, body mass index (BMI) and estimated glomerular filtration rate (eGFR) on N-terminal-pro-B-type NP (NT-proBNP) levels differ in white and black individuals. METHODS:The study population consisted of a stratified random cohort from the REasons for Geographic And Racial Differences in Stroke (REGARDS) study. The study outcomes were the effects of age, sex, BMI and eGFR on NT-proBNP levels independent of socioeconomic and cardiovascular disease factors. Multivariable regression analyses were used to assess the effects of age, sex, BMI and eGFR on NT-proBNP levels in blacks and whites. RESULTS:Of the 27,679 participants in the weighted sample, 54.7% were females, 40.6% were black, and the median age was 64?years. Every 10-year higher age was associated with 38% [95% confidence interval (CI): 30%-45%] and 34% (95% CI: 22%-43%) higher NT-proBNP levels in whites and blacks, respectively. Female sex was associated with 31% (95% CI: 20%-43%) higher NT-proBNP levels in whites and 28% (95% CI: 15%-45%) higher in blacks. There was a significant linear inverse relationship between BMI and NT-proBNP in whites and a non-linear inverse relationship in blacks. Whites and blacks had a non-linear inverse relationship between eGFR and NT-proBNP. However, the non-linear relationship between NT-proBNP and eGFR differed by race (p?=?0.01 for interaction). CONCLUSIONS:The association of age and sex with NT-proBNP levels was similar in blacks and whites but the form of the BMI and eGFR relationship differed by race.

Project description:BackgroundLimited data on the prognostic value of periprocedural changes of plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) after transcatheter aortic valve replacement (TAVR).MethodsData of plasma NT-proBNP were retrospectively collected in 357 patients before TAVR procedure and at discharge from January 1, 2018 to December 31, 2021 in our single center. Patients were grouped as responders and non-responders according to the NT-proBNP ratio (postprocedural NT-proBNP at discharge/ preprocedural NT-proBNP). Responders were defined as NT-proBNP ratio < 1 and non-responders were defined as NT-proBNP ratio ≥ 1. Outcomes were defined according to the Valve Academy Research Consortium (VARC)-3 criteria.ResultsA total of 234 patients (65.5%) and 123 patients (34.5%) were grouped as the responders and the non-responders, respectively. Responders and non-responders were significantly different in both median preprocedural (2103.5 vs. 421.0 pg/ml, p < 0.001) and postprocedural (707.6 vs. 1009.0, p < 0.001) NT-proBNP levels. Patients in the non-responder group were more inclined to have comorbidities of hypertension (73.2% vs. 51.7%, p < 0.001), hyperlipidaemia (46.3% vs. 34.6%, p = 0.031), peripheral vascular disease (20.3% vs. 8.5%, p = 0.001) and pure aortic insufficiency (15.4% vs. 4.3%, p < 0.001). In the contrast, patients in the responder group had higher prevalence of maximum transvalvular velocity (4.6 vs. 4.2 m/s, p < 0.001), reduced left ventricular ejection fraction (58.0% vs. 63.0%, p < 0.001), heart failure (9.4% vs. 2.4%, p = 0.014), mitral regurgitation ≥ moderate (13.7% vs. 4.9%, p = 0.010), tricuspid regurgitation ≥ moderate (12.0% vs. 2.4%, p = 0.002), and pulmonary hypertension (32.9% vs. 13.0%, p < 0.001). Patients in the non-responder group were moderately longer than the responder group in total hospitalization length (14 vs. 12 days, p < 0.001). The non-responder group were significantly associated with cumulative all-cause mortality (p = 0.009) and cardiac mortality (p < 0.001) during the follow-up period.ConclusionsPeriprocedural changes of NT-proBNP is clinically useful for the risk stratification of survival in patients after TAVR.
