Background: The measurements of B-type natriuretic peptide (BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) are useful for ruling out heart failure and as prognostic markers in not only heart failure populations but also general populations. It is not clear whether these two biomarkers are elevated in parallel or associated with demographic characteristics in large populations at risk of stage A heart failure. Here we investigated the relationship between BNP and NT-proBNP and extended the evaluation of this association to known demographic disparities in stage A heart failure. Methods: Of 4,310 ambulatory patients, we analyzed the cases of the 3,643 (mean age 65 ± 11 years, 46% male, and 79% on antihypertensive medication) patients whose serum BNP and NT-proBNP levels were both measured and who had a history of and/or risk factors for cardiovascular disease from the Japan Morning Surge-Home Blood Pressure (J-HOP) Study dataset. Results: The median (25th–75th percentiles) BNP and NT-proBNP values were 18.7 (9.3–38.5) pg/mL and 50.3 (25.5–97.4) pg/mL. There was a significant association between log-transformed BNP and log-transformed NT-proBNP (r = 818, p < 0.001). A multiple linear regression analysis showed that log-transformed NT-proBNP was significantly associated with log-transformed BNP (beta coefficient = 0.774, p < 0.001). When stratified by demographic characteristics, these associations remained (all p < 0.001). Conclusion: In a large Japanese population at risk of stage A heart failure, there was a significant association between BNP and NT-proBNP after adjustment and stratification by demographics.

Background: A variety of arterial stiffness measures have been used to assess the impacts of disease states and various interventions without clear consensus among them. One of the primary problems faced by…
OBJECTIVE: There is a growing demand for cuffless blood pressure (BP) measurement as an easy alternative to cuff-occlusion-based BP measurement. We assessed the accuracy of a new cuffless, watch-style BP monitor with a…
BACKGROUND/AIMS: We assessed the feasibility of renal sympathetic denervation (RDN) treatment in patients with resistant hypertension using the Iberis® RDN system. This study was a prospective, multicenter, single-arm…
BACKGROUND: Heart rate variability (HRV), pulse pressure amplification, and obesity represent risk factors for cardiovascular events. The aims of the present study are (1) to explore the impact of HRV on pulse pressure…
Introduction: A previous study of 200,000 exome-sequenced UK Biobank participants to test for association of rare coding variants with hypertension implicated two genes at exome-wide significance, DNMT3A and FES. A…
Background: Multiple piezoelectric pressure mechanotransducers topologized into an array might improve efficiency and accuracy in collecting arterial pressure waveforms for measurement of pulse wave velocity (PWV)…
Introduction: Commonly accepted clinical classification of arrhythmogenic right ventricular cardiomyopathy (ARVC) is still not developed. Objective: To study the clinical forms of ARVC. Methods: Fifty-four patients…
AIMS: Proximal aortic stiffness may be more important than carotid-femoral pulse wave velocity (cf-PWV) in the pathogenesis of heart failure. The present study investigated the associations of common carotid artery…
Patients with cardiovascular disease (CVD) commonly have subclinical depression and are often delayed in their diagnosis. Literature suggests an increased association of depression and adverse cardiovascular events like…
BACKGROUND AND PURPOSE: Stroke is a multifactorial disease influenced by both genetic and environmental factors. The aim of this case-control study was to determine the association between β-fibrinogen C148T (rs1800787)…
