Abstract
BACKGROUND With cardiovascular diseases standing as a leading cause of mortality worldwide, the interplay between diet-induced inflammation, as quantified by the Dietary Inflammatory Index (DII), and heart failure biomarker NT-proBNP has not been investigated in the general population. METHODS This study analyzed data from the National Health and Nutrition Examination Survey (NHANES) 1999-2004, encompassing 10,766 individuals. The relationship between the DII and NT-proBNP levels was evaluated through multivariable-adjusted regression models. To pinpoint crucial dietary components influencing NT-proBNP levels, the LASSO regression model was utilized. Stratified analyses were then conducted to examine the associations within specific subgroups to identify differential effects of the DII on NT-proBNP levels across diverse populations. RESULTS In individuals without heart failure, a unit increase in the DII was significantly associated with an increase in NT-proBNP levels. Specifically, NT-proBNP levels rose by 9.69 pg/mL (95% CI: 6.47, 12.91; p < 0.001) without adjustments, 8.57 pg/mL (95% CI: 4.97, 12.17; p < 0.001) after adjusting for demographic factors, and 5.54 pg/mL (95% CI: 1.75, 9.32; p = 0.001) with further adjustments for health variables. In participants with a history of heart failure, those in the second and third DII quartile showed a trend towards higher NT-proBNP levels compared to those in the lowest quartile, with increases of 717.06 pg/mL (95% CI: 76.49-1357.63, p = 0.030) and 855.49 pg/mL (95% CI: 156.57-1554.41, p = 0.018). Significant interactions were observed in subgroup analyses by age (<50: β = 3.63, p = 0.141; 50-75: β = 18.4, p<0.001; >75: β = 56.09, p<0.001), gender (men: β = 17.82, p<0.001; women: β = 7.43, p = 0.061),hypertension (β = 25.73, p<0.001) and diabetes (β = 38.94, p<0.001). CONCLUSION This study identified a positive correlation between the DII and NT-proBNP levels, suggesting a robust link between pro-inflammatory diets and increased heart failure biomarkers, with implications for dietary modifications in cardiovascular risk management.

Relationship between β1-AA and AT1-AA and Cardiac Function in Patients with Hypertension Complicated with Left Ventricular Diastolic Function Limitation. Cardiovasc Ther 2023; 2023:7611819. [PMID: 38125703 PMCID: PMC10733052 DOI: 10.1155/2023/7611819] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 10/09/2023] [Accepted: 11/15/2023] [Indexed: 12/23/2023] Open
Abstract
Objective To investigate the association between β1 adrenergic receptor autoantibodies (β1-AA) and angiotensin II type-1 receptor autoantibodies (AT1-AA) and cardiac function in patients with hypertension complicated with left ventricular diastolic function limitation. Methods A total of 120 patients with essential hypertension who were not taking drug treatment and were hospitalised in the Department of Cardiology at the authors' hospital from April 2018 to December 2018 were enrolled in this study and divided into a diastolic dysfunction group (65 cases) and a normal diastolic group (55 cases) according to their left ventricular diastolic function. The levels of cardiac parameters, β1-AA, AT1-AA, and other indicators were compared. Logistic regression analysis was used to analyse the related factors affecting left ventricular diastolic dysfunction (LVDD). The diagnostic efficacy of related factors in the diagnosis of diastolic dysfunction was evaluated. Results Univariate analysis demonstrated that the left ventricular posterior wall diameter (10.29 ± 1.23 vs. 9.12 ± 1.53), left ventricular systolic dysfunction (10.56 ± 1.37 vs. 9.43 ± 1.44), systolic blood pressure (152.37 ± 10.24 vs. 140.33 ± 5.99), diastolic blood pressure (95.66 ± 6.34 vs. 87.33 ± 7.28), β1-AA (33 vs. 9 cases), and AT1-AA (35 cases vs. 12 cases) were higher in the dysfunction group than in the control group (all P < 0.05). Multivariate regression analysis showed that β1-AA (odds ratio (OR) = 1.96, 95% confidence interval (CI): 1.369-4.345) and AT1-AA (OR = 2.02, 95% CI: 1.332-6.720) were independent risk factors for cardiac diastolic dysfunction (P < 0.05). Both autoimmune antibodies had a certain predictive value, and the combined prediction value of the two was the highest, with an area under the curve of 0.942 (95% CI: 0.881~0.985). Conclusion The positive rate of β1-AA and AT1-AA in essential hypertension patients with LVDD was higher than that in the normal group. Both β1-AA and AT1-AA could be used as early markers of LVDD in essential hypertension patients.

Effect of etelcalcetide versus alfacalcidol on left ventricular function and feature-tracking cardiac magnetic resonance imaging in hemodialysis-a post-hoc analysis of a randomized, controlled trial. J Cardiovasc Magn Reson 2023; 25:62. [PMID: 37932788 PMCID: PMC10626812 DOI: 10.1186/s12968-023-00975-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Accepted: 10/30/2023] [Indexed: 11/08/2023] Open
Abstract
BACKGROUND Calcimimetic therapy with etelcalcetide (ETEL) has been shown to attenuate the advancement of left ventricular (LV) hypertrophy in hemodialysis patients measured by cardiac magnetic resonance (CMR). The aim of the study was to evaluate whether this effect is accompanied by alterations in LV function and myocardial composition. METHODS This was a post-hoc analysis of a randomized-controlled trial of ETEL versus Alfacalcidol (ALFA) in 62 hemodialysis patients. LV function was assessed using LV ejection fraction (LVEF) and LV global longitudinal strain (GLS) on feature-tracking (FT) CMR. Myocardial tissue characteristics were analyzed using parametric T1 and T2 mapping. RESULTS Of the total study cohort (n = 62), 48 subjects completed both CMR scans with sufficient quality for FT analysis. In the one-year follow-up, LV GLS deteriorated in the ALFA group, whereas the ETEL group remained stable (LV GLS change: + 2.6 ± 4.6 versus + 0.3 ± 3.8; p = 0.045 when adjusting for randomization factors and baseline LV GLS). We did not observe a difference in the change of LVEF between the two groups (p = 0.513). The impact of ETEL treatment on LV GLS over time remained significant after additional adjustment for the change in LV mass during the study period. ETEL treatment did not significantly affect other CMR parameters. There were no changes in myocardial composition between treatment groups (T1 time change: + 15 ± 42 versus + 10 ± 50; p = 0.411; T2 time change: - 0.13 ± 2.45 versus - 0.70 ± 2.43; p = 0.652). CONCLUSIONS In patients undergoing hemodialysis, treatment with ETEL was protective against deterioration of LV longitudinal function, as evaluated through FT CMR, when compared to the control therapy of ALFA. This effect was not mediated by the change in LV mass. Trial registration URL: https://clinicaltrials.gov/ct2/show/NCT03182699 . Unique identifier: NCT03182699.

Abstract
PURPOSE We investigated the 90-day mortality rate in elderly patients who underwent hip fracture surgery and the association of preoperative cardiac function with mortality. METHODS We retrospectively enrolled 133 consecutive patients aged 80 years or older who underwent hip fracture surgery. We obtained information for patient sex, age, comorbidities, medications, anesthesia method, left ventricular systolic and diastolic functions assessed by echocardiography, and preoperative brain natriuretic peptide (BNP) levels. Multivariate logistic regression analysis was performed. RESULTS The 90-day mortality rate in patients with a mean age of 88.9 years was 7.5% (10/133). More than half of the patients had diastolic dysfunction of the left ventricle. There were no significant differences in preoperative cardiac systolic and diastolic functions between the mortality group and non-mortality group. The preoperative BNP level in the mortality group was significantly higher than that in the non-mortality group (p = 0.038). Preoperative BNP level was not an independent risk factor for 90-day mortality (p = 0.081) in the primary multivariate logistic regression analysis but was an independent risk factor (p = 0.039) with an odds ratio of 1.004 (95% CI 1.000-1.008) in the sensitivity analysis with different explanatory variables. CONCLUSION The 90-day mortality rate in patients over 80 years old after hip fracture surgery was 7.5%. There were no significant differences in preoperative cardiac function assessed by echocardiography between the mortality and non-mortality groups. Our results suggest that there is no association or only a weak association of high BNP level with 90-day mortality in this age population.

Abstract
AIMS Atrial natriuretic peptide (ANP) deficiency is thought to be one of the causes of heart failure induced by atrial fibrillation (AF). Although ANP deficiency is thought to occur as a result of atrial remodeling, data to explain this mechanism are limited. The purpose of this study was to investigate the association between ANP and left atrial remodeling or prognosis of heart failure in patients with AF ablation. METHODS In total, 373 consecutive patients who underwent initial ablation for persistent AF [age, 67 ± 10 years; female, 97 (26%)] were retrospectively enrolled. ANP and brain natriuretic peptide (BNP) were measured before the procedure and the ANP/BNP ratio was calculated. Left atrial volume index, left atrial appendage emptying velocity, and left atrial low-voltage areas (LVAs) were used as left atrial-remodeling parameters. The primary outcome of heart failure was defined as the composite of all-cause death or hospitalization due to worsening heart failure. RESULTS The median ANP level was 116 (71-178) pg/ml and the median ANP/BNP ratio was 0.65 (0.46-1.00). The ANP/BNP ratio decreased with increasing left atrial volume index or LVAs and with decreasing left atrial appendage emptying velocity. During the 5-year follow-up, freedom from the primary outcome was significantly lower in patients with ANP/BNP ratio ≤0.65 than in those with ANP/BNP ratio >0.65 (84.6% versus 95.6%, P < 0.01). CONCLUSION Secretion of ANP relative to BNP decreased with progression of left atrial remodeling in patients with AF ablation. Furthermore, prognosis of heart failure was poor in patients with a low ANP/BNP ratio.

Diagnostic accuracy of natriuretic peptide screening for left ventricular systolic dysfunction in the community: systematic review and meta-analysis. ESC Heart Fail 2023; 10:1643-1655. [PMID: 36785511 PMCID: PMC10192243 DOI: 10.1002/ehf2.14314] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2021] [Revised: 06/13/2022] [Accepted: 01/30/2023] [Indexed: 02/15/2023] Open
Abstract
AIMS Heart failure (HF) is a global health burden and new strategies to achieve timely diagnosis and early intervention are urgently needed. Natriuretic peptide (NP) testing can be used to screen for left ventricular systolic dysfunction (LVSD), but evidence on test performance is mixed, and international HF guidelines differ in their recommendations. Our aim was to summarize the evidence on diagnostic accuracy of NP screening for LVSD in general and high-risk community populations and estimate optimal screening thresholds. METHODS We searched relevant databases up to August 2020 for studies with a screened community population of over 100 adults reporting NP performance to diagnose LVSD. Study inclusion, quality assessment, and data extraction were conducted independently and in duplicate. Diagnostic test meta-analysis used hierarchical summary receiver operating characteristic curves to obtain estimates of pooled accuracy to detect LVSD, with optimal thresholds obtained to maximize the sum of sensitivity and specificity. RESULTS Twenty-four studies were identified, involving 26 565 participants: eight studies in high-risk populations (at least one cardiovascular risk factor), 12 studies in general populations, and four in both high-risk and general populations combined. For detecting LVSD in screened high-risk populations with N-terminal prohormone brain natriuretic peptide (NT-proBNP), the pooled sensitivity was 0.87 [95% confidence interval (CI) 0.73-0.94] and specificity 0.84 (95% CI 0.55-0.96); for BNP, sensitivity was 0.75 (95% CI 0.65-0.83) and specificity 0.78 (95% CI 0.72-0.84). Heterogeneity between studies was high with variations in positivity threshold. Due to a paucity of high-risk studies that assessed NP performance at multiple thresholds, it was not possible to calculate optimal thresholds for LVSD screening in high-risk populations alone. To provide an indication of where the positivity threshold might lie, the pooled accuracy for LVSD screening in high-risk and general community populations were combined and gave an optimal cut-off of 311 pg/mL [sensitivity 0.74 (95% CI 0.53-0.88), specificity 0.85 (95% CI 0.68-0.93)] for NT-proBNP and 49 pg/mL [sensitivity 0.68 (95% CI 0.45-0.85), specificity 0.81 (0.67-0.90)] for BNP. CONCLUSIONS Our findings suggest that in high-risk community populations NP screening may accurately detect LVSD, potentially providing an important opportunity for diagnosis and early intervention. Our study highlights an urgent need for further prospective studies, as well as an individual participant data meta-analysis, to more precisely evaluate diagnostic accuracy and identify optimal screening thresholds in specifically defined community-based populations to inform future guideline recommendations.

Abstract
INTRODUCTION AND AIMS Cardiac involvement in systemic sclerosis (SS) is frequently silent and a major cause of mortality in these patients. This work aims to study the prevalence and associations of left ventricular dysfunction (LVD) and arrhythmias in SS. METHODS AND RESULTS Prospective study of SS patients (n=36), excluding those with symptoms of (or) cardiac disease, pulmonary arterial hypertension or cardiovascular risk factors (CVRF). A clinical, analytical, electrocardiogram (EKG), Holter, and echocardiogram with global longitudinal strain (GLS) assessment were performed. Arrhythmias were classified into clinically significant arrhythmias (CSA) and non-significant. Twenty-eight percent had left ventricular diastolic dysfunction (LVDD), 22% LV systolic dysfunction (LVSD) according to the GLS, 11.1% both, and 16.7% cardiac dysautonomia. Fifty percent presented alterations by EKG (44% CSA), 55.6% by Holter (75% CSA) and 8.3% CSA by both. An association was found between the elevation of troponin T (TnTc) and CSA and between the elevation of both NT-proBNP and TnTc with LVDD. CONCLUSIONS We found a higher prevalence of LVSD than in the literature, detected by GLS and being 10 times higher than that detected by LVEF, which justifies the need to incorporate this technique in the routine evaluation of these patients. The association of TnTc and NT-proBNP with LVDD suggests that they can be used as minimally invasive biomarkers of this affectation. The absence of correlation between LVD and CSA indicates that the arrhythmias could be due, not only to a supposed structural alteration of the myocardium, but to an independent and early cardiac involvement, which should be actively investigated even in asymptomatic patients without CVRF.

Abstract
BACKGROUND Assessment of fluid status in neonatal dialysis has largely focused on traditional tools including clinical assessment, serial weights, and blood pressure (BP) measurements. However, in infants on kidney replacement therapy, the assessment of fluid overload is problematic due to errors in weight assessment, subtlety of physical exam findings, and inaccuracy of non-invasive BP measurements. In this presentation of a neonate with bilateral renal agenesis requiring kidney replacement therapy, the treating team assessed a number of variables in determining the ultrafiltration prescription for dialysis across 2 modalities (hemodialysis and continuous kidney replacement therapy). COMPLICATIONS Fluid overload, cardiomegaly, and worsened respiratory status occurred when attempting to assess the neonate's fluid status by traditional markers (weights, blood pressures, physical exam findings). B-type natriuretic peptide (BNP) was obtained and was noted to correlate with the degree of fluid overload. KEY MANAGEMENT POINTS Compared to traditional tools for assessment of fluid status in pediatric dialysis, BNP assisted the medical team in optimizing the volume status of the subject and determining optimal daily ultrafiltration goals. Due to the rapid release in response to myocardial stretch and the lack of kidney clearance of the peptide, BNP may represent an objective, timely, and reliable index of volume status in the pediatric dialysis patient.

Abstract
Background: Rheumatoid arthritis (RA) increases the risk for abnormalities of the cardiac structure and function, which may lead to heart failure (HF). Studying the association between circulating biomarkers and echocardiographic parameters is important to screen patients with RA with a higher risk of cardiac dysfunction. Aim: To study the association between circulating biomarkers and echocardiographic parameters in patients with RA. Methods: Echocardiography was performed in 355 patients with RA from RA Porto cohort and the associations between echocardiographic characteristics and 94 circulating biomarkers were assessed. These associations were also assessed in the Metabolic Road to Diastolic Heart Failure (MEDIA-DHF) [392 patients with HF with preserved ejection fraction (HFpEF)] and the Suivi Temporaire Annuel Non-Invasif de la Santé des Lorrains Assurés Sociaux (STANISLAS) (1,672 healthy population) cohorts. Results: In the RA Porto cohort, mean age was 58 ± 13 years, 23% were males and mean RA duration was 12 ± 10 years. After adjustment and multiple testing correction, left ventricular mass index (LVMi), left atrial volume index (LAVi), and E/e′ were independently associated with biomarkers reflecting inflammation [i.e., bone morphogenetic protein 9 (BMP9), pentraxin-related protein 3 (PTX3), tumor necrosis factor receptor superfamily member 11a (TNFRSF11A)], extracellular matrix remodeling [i.e., placental growth factor (PGF)], congestion [i.e., N-terminal pro-brain natriuretic peptide (NT-proBNP), adrenomedullin (ADM)], and myocardial injury (e.g., troponin). Greater LVMi [hazard ratio (HR) (95% CI) per 1 g/m2 = 1.03 (1.02–1.04), p < 0.001], LAVi [HR (95% CI) per 1 ml/m2 = 1.03 (1.01–1.06), p < 0.001], and E/e′ [HR (95% CI) per 1 = 1.08 (1.04–1.13), p < 0.001] were associated with higher rates of cardiovascular events. These associations were externally replicated in patients with HFpEF and asymptomatic individuals. Conclusion: Circulating biomarkers reflecting inflammation, extracellular matrix remodeling, congestion, and myocardial injury were associated with underlying alterations of cardiac structure and function. Biomarkers might be used for the screening of cardiac alterations in patients with RA.

B-Type Natriuretic Peptide Is Associated with Indices of Left Ventricular Dysfunction in Healthy Subjects from the General Population: The Akershus Cardiac Examination 1950 Study. Clin Chem 2021; 67:204-215. [PMID: 33279958 DOI: 10.1093/clinchem/hvaa257] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Accepted: 10/12/2020] [Indexed: 01/15/2023]
Abstract
BACKGROUND Concentrations of B-type natriuretic peptide (BNP) reflect myocardial distension and stress, and are associated with poor prognosis in patients with cardiovascular disease. Accordingly, we hypothesized that concentrations of BNP would be associated with indices of adverse left ventricular (LV) remodeling and early stages of LV systolic and diastolic dysfunction in healthy participants from the general population. METHODS We measured BNP in 1757 women and 1677 men free from known coronary heart disease participating in the prospective observational Akershus Cardiac Examination 1950 Study. All study participants underwent extensive cardiovascular phenotyping at baseline, including detailed echocardiography with assessment of indexed LV mass (LVMI), diastolic [tissue Doppler e', E/e' ratio, indexed left atrial volume (LAVI), maximal tricuspid regurgitation velocity (TRVmax), and E/A ratio], and systolic [global longitudinal strain (GLS) and LV ejection fraction (LVEF)] function. RESULTS Study participants with the highest BNP concentrations had higher GLS, LVMI, e', E/e' ratio, LAVI, TRVmax, and E/A ratio. In adjusted analyses, both GLS and LVEF exhibited significant nonlinear associations with BNP, with reduced LV systolic function observed in both the low and high concentration range of BNP. CONCLUSIONS In healthy participants recruited from the general population, concentrations of BNP exhibit nonlinear associations with LV systolic function, and both low and high concentrations are associated with reduced LV systolic function. This supports the notion that natriuretic peptides are beneficial and elicit cardioprotective effects, and may have important implications for the interpretation of BNP measurements in the general population.

Abstract
Background Clinical effectiveness of autologous skeletal cell‐patch implantation for nonischemic dilated cardiomyopathy has not been clearly elucidated in clinical settings. This clinical study aimed to determine the feasibility, safety, therapeutic efficacy, and the predictor of responders of this treatment in patients with nonischemic dilated cardiomyopathy. Methods and Results Twenty‐four nonischemic dilated cardiomyopathy patients with left ventricular ejection fraction <35% on optimal medical therapy were enrolled. Autologous cell patches were implanted over the surface of the left ventricle through left minithoracotomy without procedure‐related complications and lethal arrhythmia. We identified 13 responders and 11 nonresponders using the combined indicator of a major cardiac adverse event and incidence of heart failure event. In the responders, symptoms, exercise capacity, and cardiac performance were improved postoperatively (New York Heart Association class II 7 [54%] and III 6 [46%] to New York Heart Association class II 12 [92%] and I 1 [8%], P<0.05, 6‐minute walk test; 471 m [370–541 m] to 525 m [425–555 m], P<0.05, left ventricular stroke work index; 31.1 g·m2·beat [22.7–35.5 g·m2·beat] to 32.8 g·m2·beat [28–38.5 g·m2·beat], P=0.21). However, such improvement was not observed in the nonresponders. In responders, the actuarial survival rate was 90.9±8.7% at 5 years, which was superior to the estimated survival rate of 70.9±5.4% using the Seattle Heart Failure Model. However, they were similar in nonresponders (47.7±21.6% and 56.3±8.1%, respectively). Multivariate regression model with B‐type natriuretic peptide, pulmonary capillary wedge pressure, and expression of histone H3K4me3 (H3 lysine 4 trimethylation) strongly predicted the responder of this treatment (B‐type natriuretic peptide: odds ratio [OR], 0.96; pulmonary capillary wedge pressure: OR, 0.58; H3K4me3: OR, 1.35, receiver operating characteristic–area under the curve, 0.96, P<0.001). Conclusions This clinical trial demonstrated that autologous skeletal stem cell–patch implantation might promise functional recovery and good clinical outcome in selected patients with nonischemic dilated cardiomyopathy, in addition to safety and feasibility.

Abstract
Inflammatory cardiomyopathy diagnosed by endomyocardial biopsy (EMB) is common in non-ischemic heart failure (HF) and might be associated with adverse outcome. We aimed to identify markers predicting myocardial inflammation in HF. We screened 517 patients with symptomatic non-ischemic HF who underwent EMB; 397 patients (median age 54 [IQR 43/64], 28.7% females) were included in this study. 230 patients were diagnosed with myocardial inflammation, defined as ≥ 7.0 CD3+ lymphocytes/mm2 and/or ≥ 35.0 Mac1 macrophages/mm2 and were compared to 167 inflammation negative patients. Patients with myocardial inflammation were more often smokers (52.4% vs. 39.8%, p = 0.013) and had higher C-reactive protein (CRP) levels (5.4 mg/dl vs. 3.7 mg/dl, p = 0.003). In logistic regression models CRP ≥ 8.15 mg/dl (OR 1.985 [95%CI 1.160–3.397]; p = 0.012) and Troponin I (TnI) ≥ 136.5 pg/ml (OR 3.011 [1.215–7.464]; p = 0.017) were independently associated with myocardial inflammation, whereas no association was found for elevated brain natriuretic peptide (OR 1.811 [0.873–3.757]; p = 0.111). In prognostic performance calculation the highest positive predictive value (90%) was detected for the combination of Global longitudinal strain (GLS) ≥ -13.95% and TnI ≥ 136.5 pg/ml (0.90 (0.74–0.96)). Elevated CRP, TnI and GLS in combination with TnI can be useful to detect myocardial inflammation. Smoking seems to predispose for myocardial inflammation.

Serum B-type natriuretic peptide does not increase with higher systolic blood pressure in obese men despite evidence of blood pressure-related increases in left ventricular mass and filling pressure. Peptides 2020; 134:170390. [PMID: 32882353 DOI: 10.1016/j.peptides.2020.170390] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2020] [Revised: 08/22/2020] [Accepted: 08/24/2020] [Indexed: 11/27/2022]
Abstract
B-type natriuretic peptide (BNP) is a cardiac hormone secreted predominantly from the ventricles in response to increased ventricular pressure. Along this line, hypertensive patients with left ventricular hypertrophy typically have high circulating BNP concentrations. BNP has natriuretic and vasodilatory actions. Obese persons have low circulating BNP concentrations, and a relative lack of this natriuretic and vasodilatory factor could contribute to obesity-related hypertension. The relationship between BNP, BP, left ventricular mass (LVM), and left ventricular filling pressure among obese persons is not clear. To address this issue, we studied 98 healthy obese medication-free men with normal left ventricular ejection fraction. We measured BP using 24 -h ambulatory (A) BP recordings, LVM and E/e', an estimate of left ventricular filling pressure, using echocardiography, and fasting BNP in serum. Mean systolic ABP ± SD was 114 ± 4 mm Hg in 1st and 149 ± 8 mm Hg in 4th systolic ABP quartile, P < 0.001. LVM and E/e' increased across systolic ABP quartiles (mean LVM±SD: 81.5±13.7 g/m2 in 1st and 100.1 ± 26.7 g/m2 in 4th quartile, P = 0.018; mean E/e'±SD: 5.3±1.6 in 1st and 7.0 ± 2.0 in 4th quartile, P = 0.002). In contrast, serum BNP did not increase across systolic ABP quartiles (median (IQR): 6.7 (3.1-12.3) pg/ml in 1st and 5.3 (2.8-9.7) pg/ml in 4th quartile, P = 0.75). Unexpectedly, among healthy obese medication-free men, serum BNP does not increase with higher systolic ABP despite evidence of BP-related increases in LVM and E/e'. This further suggests that a relatively low amount of circulating BNP could contribute to obesity-related hypertension in its early stages.

Natriuretic peptides for the detection of diastolic dysfunction and heart failure with preserved ejection fraction-a systematic review and meta-analysis. BMC Med 2020; 18:290.

Abstract
BACKGROUND An overview of the diagnostic performance of natriuretic peptides (NPs) for the detection of diastolic dysfunction (DD) and heart failure with preserved ejection fraction (HFpEF), in a non-acute setting, is currently lacking. METHODS We performed a systematic literature search in PubMed and Embase.com (May 13, 2019). Studies were included when they (1) reported diagnostic performance measures, (2) are for the detection of DD or HFpEF in a non-acute setting, (3) are compared with a control group without DD or HFpEF or with patients with heart failure with reduced ejection fraction, (4) are in a cross-sectional design. Two investigators independently assessed risk of bias of the included studies according to the QUADAS-2 checklist. Results were meta-analysed when three or more studies reported a similar diagnostic measure. RESULTS From 11,728 titles/abstracts, we included 51 studies. The meta-analysis indicated a reasonable diagnostic performance for both NPs for the detection of DD and HFpEF based on AUC values of approximately 0.80 (0.73-0.87; I2 = 86%). For both NPs, sensitivity was lower than specificity for the detection of DD and HFpEF: approximately 65% (51-85%; I2 = 95%) versus 80% (70-90%; I2 = 97%), respectively. Both NPs have adequate ability to rule out DD: negative predictive value of approximately 85% (78-93%; I2 = 95%). The ability of both NPs to prove DD is lower: positive predictive value of approximately 60% (30-90%; I2 = 99%). CONCLUSION The diagnostic performance of NPs for the detection of DD and HFpEF is reasonable. However, they may be used to rule out DD or HFpEF, and not for the diagnosis of DD or HFpEF.

Abstract
BACKGROUND N-terminal pro B-type natriuretic peptide (NT-proBNP) and cardiac troponin-I (cTnI) are biomarkers commonly evaluated in cats with suspected heart disease. Many cats with hypertrophic cardiomyopathy (HCM) have systolic anterior motion of the mitral valve (SAM), but its influence on circulating NT-proBNP or cTnI concentrations is currently unknown. HYPOTHESIS/OBJECTIVES Cats with HCM and SAM (HCMSAM+ ) have higher NT-proBNP and cTnI concentrations than do cats with HCM but without SAM (HCMSAM- ). ANIMALS One hundred forty cats with HCM: 70 with SAM and 70 without SAM. METHODS Retrospective case-to-case study. Cats were recruited if diagnosed with HCM by echocardiography and results were available for NT-proBNP or cTnI concentrations or both. Cats with SAM were matched to those without SAM for clinical presentation, left atrial (LA) size and left ventricular (LV) fractional shortening. RESULTS A total of 119 NT-proBNP and 123 cTnI results were available. The HCMSAM+ cats had higher median concentrations than did HCMSAM- cats for NT-proBNP (729 pmoL/L; interquartile range [IQR], 275-1467 versus 65 pmoL/L; IQR, 25-271; P < .001) and cTnI (0.27 ng/mL; IQR, 0.10-0.81 versus 0.07 ng/mL; IQR, 0.01-0.43; P = .002). In general linear models for both NT-proBNP and cTnI, the independent explanatory variables were SAM, congestive heart failure, maximal LV wall thickness, and LA size. CONCLUSIONS AND CLINICAL IMPORTANCE For cats with HCM and equivalent LA size and LV systolic function, those with SAM had higher NT-proBNP and cTnI concentrations than did those without SAM. Presence of SAM should be considered when interpreting biomarker concentrations in cats with HCM.

Abstract
Objective: To evaluate the concentration of N terminal proBNP (NT-proBNP) and partially the serum uric acid in the severe condition of aortic valve dysfunction for assessment of left ventricle hypertrophy. Methods: The study was conducted in the signal transduction lab department of biochemistry Quaid-I-Azam University, Islamabad from September 2013 to February 2017. NT-proBNP and serum uric acid were measured in one hundred patients of aortic valve dysfunction. The patients were divided into three main groups: 1) Aortic stenosis, 2) Aortic regurgitation, and 3) Aortic stenosis with Aortic regurgitation. The results were compared between disease and controls groups. Results: High level of plasma NT-proBNP was detected in all the three disease groups of aortic valve (stenosis, p<0.001), (regurgitation, p<0.001) and (stenosis with regurgitation, p<0.001). In addition, non-significantly increased level of serum uric acid was also observed in left ventricle hypertrophy in all the three respective disease groups of aortic valve. Conclusion: Increased secretion of NT-proBNP during cardiac remodeling can be related to the severity of left ventricle hypertrophy due to aortic valve abnormality in all the disease groups of severe stenosis, severe regurgitation, and combine disease condition of severe stenosis and severe regurgitation. However, non-significant increase in uric acid concentration is also identified which may be due to one of the factors involved in left ventricle hypertrophy in all the three disease groups of aortic valve. The interaction of uric acid with NT-proBNP during cardiac remolding due to aortic valve dysfunction is still not clear.

[PMID: 29746994 DOI: 10.1016/j.jep.2018.05.006] [Citation(s) in RCA: 32] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/11/2018] [Revised: 05/03/2018] [Accepted: 05/06/2018] [Indexed: 06/08/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Shenfu decoction consists of the water extract from the dried root or rootstalk of Panax ginseng C. A. Mey (Asian ginseng) and the lateral root of Aconitum carmichaeli Debx (Fuzi, Heishunpian in Chinese). Shenfu Formula has been used as a folk Chinese medicine for thousands of years. Recent studies have shown that Shenfu injection can enhance cardiac function and regulate arrhythmia. AIM OF THE STUDY Shenfu Formula plays an important role in the treatment of heart failure. However, its microRNA-mediated mechanisms are still not fully understood. Thus, we established a heart failure model in rats to investigate the microRNA mechanism of Shenfu Formula in cardiac function and apoptosis. MATERIALS AND METHODS The heart failure animal model was established via left-anterior descending coronary artery ligation in rats. Seven days after surgery, Shenfu Formula was given to the heart failure rats, which were selected by echocardiography with an LVEF< 45%. After Shenfu Formula was given intragastrically for 30 days, blood samples were drawn, the heart was excised after echocardiography, and echocardiographic parameters and apoptosis-related proteins were further examined. Fas/Fas-L and Bcl-2/Bax proteins were analyzed by Western blot, and microRNAs were evaluated using Affymetrix GeneChip miRNA arrays. RESULTS Shenfu Formula increased the left ventricular ejection fraction, improved the hemodynamic index of heart failure rats, and decreased serum brain natriuretic peptide (BNP) levels. Shenfu Formula also decreased the positive rate of myocardial cells as detected by the TUNEL method and significantly suppressed caspase 3 expression. Moreover, we found that Shenfu Formula can regulate the initiative factors Fas/Fas-L in the intrinsic pathway and Bcl-2/Bax in the extrinsic apoptosis pathway to suppress apoptosis in heart failure rats. Finally, Shenfu Formula potentially alters the balance of microRNAs involved in activating and inhibiting apoptosis, ultimately suppressing apoptosis; this leads to changes in the gene expression profiles of microRNAs targets. CONCLUSION Shenfu Granule can effectively improve cardiac function in heart failure rats, and the anti-apoptosis effects of Shenfu Formula are potential mechanisms for inhibiting heart failure.

Abstract
OBJECTIVES Although B-type natriuretic peptide (BNP) and highly sensitive cardiac troponin T (cTnT) are useful for the evaluation of clinical features in various cardiovascular diseases, there are comparatively few data regarding the utility of these parameters in patients with hypertrophic obstructive cardiomyopathy (HOCM). The goal of this study was to assess the association between BNP, cTnT and clinical parameters in patients with HOCM. DESIGN Cross-sectional survey SETTINGS The relationship between BNP, cTnT and clinical end points and echocardiographic data was investigated. PARTICIPANTS This study included 102 consecutive outpatients with HOCM who were clinically stable. RESULTS BNP was significantly associated with both maximum left ventricular (LV) wall thickness (r=0.28; p=0.003), and septal peak early transmitral filling velocity/peak early diastolic mitral annulus velocity (r=0.51; p=0.0001). No statistically significant associations were seen between cTnT and any echocardiographic parameters, but the presence of atrial fibrillation (AF) was associated with a high level of cTnT (p=0.01). CONCLUSIONS BNP is useful for monitoring clinical parameters and as a reflection of both LV systolic/diastolic function and increased LV pressure in patients with HOCM. A high level of serum cTnT is associated with the presence of AF.

Abstract
AIMS Diastolic dysfunction is common in geriatric heart failure. A reliable parameter to predict myocardium stiffness and relaxation under similar end-diastolic pressure is being developed. We propose a material and mathematical model for calculating myocardium stiffness based on the concept of linear correlation between [Formula: see text] and wedge pressure. METHODS AND RESULTS We enrolled 919 patients (male: [Formula: see text][Formula: see text]). Compared with the younger population of controls (mean age: [Formula: see text] years; [Formula: see text]; male: [Formula: see text] [Formula: see text]), the elderly (mean age: [Formula: see text]; [Formula: see text]; male: [Formula: see text] [Formula: see text]) had a greater prevalence of hypertension, diabetes mellitus, and coronary artery disease (all [Formula: see text]). We collected their M-mode and 2-D echocardiographic volumetric parameters, intraventricular filling pressure, and speckle tracking images to establish a mathematical model. The feasibility of this model was validated. The average early diastolic velocity of the mitral annulus assessed using tissue Doppler imaging was significantly attenuated in the elderly ([Formula: see text]: [Formula: see text] vs. [Formula: see text]; [Formula: see text]) and corresponded to the higher estimated wedge ([Formula: see text]) pressure ([Formula: see text] vs. [Formula: see text]; [Formula: see text]) in that cohort. E (Young's modulus) was calculated to describe the tensile elasticity of the myocardium. With the same intraventricular filling pressure, E was significantly higher in the elderly, especially those with [Formula: see text] values [Formula: see text]. Compared with diastolic dysfunction parameters, E also presented sentinel characteristics more sensitive for detecting early myocardial relaxation impairment, which indicates stiffer myocardium in aging hearts. CONCLUSION Our material and geometric mathematical model successfully described the stiffer myocardium in aging hearts with higher intraventricular pressure. Additional studies that compare individual differences, especially in health status, are needed to validate its application for detecting diastolic heart failure.

Abstract
OBJECTIVE Diabetes is associated with left ventricular (LV) diastolic and systolic dysfunction. South Asians may be at particular risk of developing LV dysfunction owing to a high prevalence of diabetes. We investigated the role of diabetes and hyperglycemia in LV dysfunction in a community-based cohort of older South Asians and white Europeans. RESEARCH DESIGN AND METHODS Conventional and Doppler echocardiography was performed in 999 participants (542 Europeans and 457 South Asians aged 58-86 years) in a population-based study. Anthropometry, fasting bloods, coronary artery calcification scoring, blood pressure, and renal function were measured. RESULTS Diabetes and hyperglycemia across the spectrum of HbA1c had a greater adverse effect on LV function in South Asians than Europeans (N-terminal-probrain natriuretic peptide β ± SE 0.09 ± 0.04, P = 0.01, vs. -0.04 ± 0.05, P = 0.4, P for HbA1c/ethnicity interaction 0.02), diastolic function (E/e' 0.69 ± 0.12, P < 0.0001, vs. 0.09 ± 0.2, P = 0.6, P for interaction 0.005), and systolic function (s' -0.11 ± 0.06, P = 0.04, vs. 0.14 ± 0.09, P = 0.1, P for interaction 0.2). Multivariable adjustment for hypertension, microvascular disease, LV mass, coronary disease, and dyslipidemia only partially accounted for the ethnic differences. Adverse LV function in diabetic South Asians could not be accounted for by poorer glycemic control or longer diabetes duration. CONCLUSIONS Diabetes and hyperglycemia have a greater adverse effect on LV function in South Asians than Europeans, incompletely explained by adverse risk factors. South Asians may require earlier and more aggressive treatment of their cardiometabolic risk factors to reduce risks of LV dysfunction.

Abstract
AbstractHeart failure with normal ejection fraction (HFNEF) accounts for approximately 50% of heart failure (HF) cases. To establish the utility of brain natriuretic peptide (BNP) in differentiating HF-related severe dyspnea from non-HF-related acute dyspnea, we used an estimation formula (eF) that was obtained from a series of three meta-regressions. We selected 60 out of 2721 case-control and follow-up studies that were published from 1998 to 2010. The heart failure levels (HFLs) were assessed using the New York Heart Association (NYHA) criteria. Random-effects meta-regression analyses of the natural logarithm (ln) of the BNP odds ratio (OR) were performed on the HFLs. The ln of the median BNP values (lnmBNP) was meta-regressed over the laboratory method (LM). A third meta-regression was performed on the HFLs to account for only the lnmBNP in the homogeneous LM subgroups. To determine the eF, the data from the diseased and control subjects were combined. The Bland-Altman method was used to detect eF bias. The overall BNP(OR) in the subgroup with severe HF was 35. The lnmBNP analysis showed that LM was a significant heterogeneity factor in the meta-regression (slope −0.38; CI −0.59 to −0.16). The meta-regression of lnmBNP on the HFL resulted in the following calculation for eF: estimated HFL (eHFL)=(lnmBNP–3.157)/0.886. The Bland-Altman test revealed no significant difference (0.0997; 95% CI −2.84 to 3.06) between HFL and eHFL. The severe eHFL showed a 78% accuracy. Based on the eF obtained from this meta-analysis, the BNP outcomes were shown to reliably diagnose severe dyspnea in HF and differentiate this condition from non-HF acute dyspnea.

Abstract
Pulmonary hypertension (PH) is commonly seen in patients who present with left ventricular diastolic dysfunction (LVDD) and is considered a marker of poor prognosis. While PH in this setting is thought to result from pulmonary venous congestion, there is a subset of patients in which pulmonary pressures fail to improve with appropriate management of diastolic heart failure and go on to develop a clinical picture similar to that of patients with pulmonary arterial hypertension (PAH). Despite the utility of Doppler echocardiography and exercise testing in the initial evaluation of patients with suspected PH-LVDD, the diagnosis can only be confirmed using right heart catheterization. Management of PH-LVDD centers on both optimizing fluid management and afterload reduction to reducing left ventricular diastolic pressures and also increase pulmonary venous return. To date, there is no clear evidence that addition of PH-specific drugs can improve clinical outcomes, and their use should only be considered in the setting of clinical trials. In conclusion, PH-LVDD remains a challenging clinical entity that complicates the management of left ventricular dysfunction and significantly contributes to its morbidity and mortality. Determination of the optimal diagnostic and treatment strategies for this form of PH should be the goal of future studies.

Abstract
The role of biomarkers in the management of patients with acute heart failure (HF) has evolved rapidly in the past several years. Representing a major burden on health systems, acute HF has increased the need for earlier diagnosis, better risk stratification, and cost-effective treatment to reduce rates of hospitalization. Biomarker-guided diagnosis and treatment have become essential, especially in the acute setting to which the majority of the patients with acute HF initially present. Studies clearly demonstrate the complexity of these patients, who commonly have multiple comorbidities necessitating an integrative approach. Several groundbreaking studies conducted in the past decade have demonstrated how biomarkers, individually or in combination, can outperform conventional laboratory tests used in the emergency department as well as in hospitalized patients with acute HF. In this Review, we will provide an update on biomarkers considered state of the art in the diagnosis and management of patients with acute HF.

Abstract
UNLABELLED Serum biomarkers, such as B-type natriuretic peptide and troponin, are frequently measured in the cardiac intensive care unit. A review of the evidence supporting monitoring of these biomarkers is presented. DESIGN A search of MEDLINE, PubMed, and the Cochrane Database was conducted to find literature regarding the use of B-type natriuretic peptide and troponin in the cardiac intensive care setting. Adult and pediatric data were considered. RESULTS AND CONCLUSION Both B-type natriuretic peptide and troponin have demonstrated utility in the intensive care setting but there is no conclusive evidence at this time that either biomarker can be used to guide inpatient management of children with cardiac disease. Although B-type natriuretic peptide and troponin concentrations can alert clinicians to myocardial stress, injury, or hemodynamic alterations, the levels can also be elevated in a variety of clinical scenarios, including sepsis. Observational studies have demonstrated that perioperative measurement of these biomarkers can predict postoperative mortality and complications. RECOMMENDATION AND LEVEL OF EVIDENCE (class IIb, level of evidence B): The use of B-type natriuretic peptide and/or troponin measurements in the evaluation of hemodynamics and postoperative outcome in pediatric cardiac patients may be beneficial.

Abstract
BACKGROUND To determine whether automated office blood pressure (AOBP) readings are associated with left ventricular mass (LVM) index as closely as those of 24-h ambulatory blood pressure (ABP) and also to confirm that the values of the two methods are comparable in the appraisal of blood pressure in a European population referred for suspected hypertension. METHODS In a sample of 90 individuals with office hypertension, we compared AOBP to awake systolic ABP measurements (ABPM) values and their associations with LVM indices, expressed as LVM divided by body surface area (LVMI(BSA)) and by height(2.7) (LVMI(H)). RESULTS Mean awake systolic ABP was 136 ± 16 mm Hg and mean systolic AOBP was 140 ± 15 mm Hg (P < 0.002). Mean awake diastolic ABP was 87 ± 11 mm Hg and mean diastolic AOBP was 88 ± 12 mm Hg (P = 0.08). AOBP readings were as closely associated with LVMI(BSA) (r = 0.37) as were those of awake systolic blood pressure (SBP) (r = 0.37). The correlation between LVMI(H) and both mean awake systolic ABP and mean systolic AOBP was r = 0.37 (P < 0.001) and r = 0.34 (P = 0.001), respectively. CONCLUSIONS High-quality AOBP readings and ABP measurements correlate equally well with LVM indices, further supporting the use of AOBP in the clinical setting. Moreover, readings from both techniques are comparable in the assessment of blood pressure.

Abstract
INTRODUCTION The growing number of heart failure (HF) patients is becoming an important issue in cardiology. B-type natriuretic peptide (BNP) is a recognized marker of HF, including in patients with preserved systolic function. The TEI index is an indicator of left ventricular function. The aim of the study was to evaluate the relationship between BNP serum level, TEI index and the degree of diastolic dysfunction in patients with HF symptoms and preserved systolic function. MATERIAL AND METHODS Hundred patients with arterial hypertension and preserved systolic function were enrolled in the study. The study group consisted of 51 individuals with impaired diastolic function and HF symptoms. Fourty-nine hypertensive individuals without HF symptoms were assigned to the control group. B-type natriuretic peptide and echocardiographic examination were performed. Patients were divided into 4 subgroups - with normal diastolic function, impaired relaxation, pseudonormalization and restriction. RESULTS Median value of BNP in patients with normal diastolic function was 28.36 pg/ml, 87.10 pg/ml in patients with impaired relaxation, 212.75 pg/ml and 461.56 pg/ml in the pseudonormalization and restriction group respectively (p < 0.0001). The median value of the TEI index was: 0.386 in patients with normal diastolic function, 0.507 in individuals with impaired relaxation, 0.639 and 0.725 in the pseudonormalization and restriction group respectively. All the differences were statistically significant (p < 0.0001). A significant positive correlation (r = 0.80, p < 0.001) between BNP and the TEI index was found. CONCLUSIONS In hypertensive patients with HF symptoms and preserved left ventricular systolic function a highly significant increase in BNP serum level and in the TEI index values related to the deterioration of diastolic dysfunction was found.

Abstract
This study tested the hypothesis that experimental prediabetes can elicit structural remodelling in the left ventricle (LV). Left ventricles isolated from 8-week-old male Goto-Kakizaki (GK) rats and age-matched male Wistar control rats were used to assess remodelling changes and underlying transforming growth factor β1 (TGFβ1) activity, prohypertrophic Akt-p70S6K1 signalling and gene expression profile of the extracellular matrix (ECM) using histological, immunohistochemical, immunoblotting and quantitative gene expression analyses. Prediabetes in GK rats was confirmed by impaired glucose tolerance and modestly elevated fasting blood glucose. Left ventricle remodelling in the GK rat presented with marked hypertrophy of cardiomyocytes and increased ECM deposition that together translated into increased heart size in the absence of ultrastructural changes or fibre disarray. Molecular derangements underlying this phenotype included recapitulation of the fetal gene phenotype markers B-type natriuretic peptide and α-skeletal muscle actin, activation of the Akt-p70S6K1 pathway and altered gene expression profile of key components (collagen 1α and fibronectin) and modulators of the ECM (matrix metalloproteinases 2 and 9 and connective tissue growth factor). These changes were correlated with parallel findings of increased TGFβ1 transcription and activation in the LV and elevated active TGFβ1 in plasma of GK rats compared with control animals (Student's t test, P < 0.05 versus age-matched Wistar control animals for all parameters). This is the first report to describe LV structural remodelling in experimental prediabetes. The results suggest that ventricular decompensation pathognomonic of advanced diabetic cardiomyopathy may have possible origins in profibrotic and prohypertrophic mechanisms triggered before the onset of type 2 diabetes mellitus.

Abstract
For patients presenting with acute dyspnea, an incorrect diagnosis could increase the mortality risk. When used in the evaluation of patients with acute symptoms, brain natriuretic peptide and N-terminal pro-brain natriuretic peptide (BNP and NT-proBNP, respectively) testing is highly sensitive for the diagnosis or exclusion of acute or chronic decompensated heart failure (HF). It has been demonstrated that BNP and proBNP levels can facilitate diagnosis and guide HF therapy. Natriuretic peptide (NP) levels are strictly related with HF severity; they are particularly increased in more advanced New York Heart Association (NYHA) classes and in patients with poor outcome. Therefore elevated NP levels were found to correlate with the severity of left ventricular systolic dysfunction, right ventricular dysfunction and pressures, and left ventricular filling alterations. However, the optimal use of NP determination agrees with patient history, physical examination, and all other diagnostic tools. There are some clinical conditions (ie, obesity, renal insufficiency anemia) for which the NP measurement is not diagnostic. Algorithm building taking into consideration all clinical and echocardiographic parameters, as well as NP measurements, may lead to the earlier identification and better risk stratification of patients with chronic HF, independently from etiology.

Abstract
BACKGROUND The causes of elevated B-Type natriuretic peptide (BNP) levels are multifactorial. Renal dysfunction has been shown to affect BNP levels in some studies and the diagnostic value of BNP levels in the presence of chronic kidney disease has been questioned. Prior studies have involved small patient populations with variable outcomes noted. This study evaluated the association of BNP levels with an estimated glomerular filtration rate (eGFR) and presence or absence of congestive heart failure (CHF). METHODS A retrospective, cross-sectional study in which medical records were electronically screened, identified patients with a BNP level and serum creatinine measurement on the same day between December 2002 and March 2006. RESULTS Of 1739 eligible patients, 537 were positive for CHF and 1202 were negative for CHF by our criteria. There was a clear trend for BNP to be higher with the advancement of CHF, as determined by New York Heart Association (NYHA) classification (P<0.001). Median BNP levels increased from 65 pg/mL in patients without CHF to 496 pg/mL in patients with NYHA class IV CHF (P <0.001), and there was a strong inverse association with eGFR (P <0.001). CONCLUSION BNP levels show a strong inverse association with eGFR in both CHF and non-CHF patients. Currently best practice at most institutions involves use of BNP cutoff diagnostic levels not adjusted for eGFR. The data presented underlines that eGFR is a significant confounder of BNP measurement especially when renal status is compromised and interpretation of clinical significance in the presence of elevated BNP measures should take renal status into consideration.

Abstract
Background The aims of this study were to estimate the prevalence of left ventricular systolic (LVSD) and diastolic (LVDD) dysfunction, and to test if BNP and urinary albumin excretion rate (AER) are related to LVSD, LVD and left ventricular mass (LVM) in asymptomatic type 2 diabetes patients. Methods Presence of LVSD, LVDD and LVM, determined with echocardiography, was related to levels of BNP and AER in 153 consecutive asymptomatic patients with type 2 diabetes. Results LVSD was present in 6.1% of patients whereas 49% (29% mild, 19% moderate and 0.7% severe) had LVDD and 9.4% had left ventricular hypertrophy. Increasing age (P < 0.0001) was the only independent variable related to mild LVDD whereas increasing BNP (P = 0.01), systolic blood pressure (P = 0.01), age (P = 0.003) and female gender (P = 0.04) were independent determinants of moderate to severe LVDD. AER (P = 0.003), age (P = 0.01) and male gender (P = 0.006) were directly and independently related to LVM. Conclusion About half of asymptomatic type 2 diabetes patients have LVDD. Of those, more than one third display moderate LVDD pattern paralleled by increases in BNP, suggesting markedly increased risk of heart failure, especially in females, whereas AER and male sex are related to LVM.

Abstract
BACKGROUND AND OBJECTIVES B-type natriuretic peptide (BNP) and amino-terminal pro-B-type natriuretic peptide (NT-proBNP) are biomarkers of cardiovascular disease that is common in patients with chronic kidney disease (CKD). Conflicting data on the influence of glomerular filtration rate (GFR) on BNP and NT-proBNP levels in CKD may stem from failure to account fully for the effects of coexistent cardiac disease, dysfunction, and volume overload. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Prospective head-to-head comparison of plasma BNP and NT-proBNP in ambulatory euvolemic CKD patients with normal LV ejection fraction and no manifest cardiac or vascular disease. GFR was estimated by the Modification of Diet in Renal Disease formula, BNP and NT-proBNP measured using Abbott AxSYM and Roche Elecsys assays, respectively, and cardiac morphology and function assessed by transthoracic echocardiography. RESULTS In 142 patients (42% female) of mean age 60 +/- 11 yr, mean left ventricular ejection fraction was 71% +/- 6%, GFR 38 +/- 14 ml/min per 1.73 m(2), and median BNP and NT-proBNP level 59 and 311 pg/ml, respectively. Multivariate predictors of NT-proBNP level were GFR, beta-blocker usage, LV mass index, and hemoglobin level. Plasma BNP was independently predicted by LV mass index and beta-blocker usage but not GFR. In the 74 patients without diastolic dysfunction, there was a significant rise in NT-proBNP but not BNP as GFR declined. CONCLUSIONS Unlike NT-proBNP, plasma BNP level is relatively independent of GFR. BNP may therefore be the more appropriate biomarker to screen for cardiac dysfunction in CKD.

Abstract
OBJECTIVES Changes in B-type natriuretic peptide (BNP) and electrocardiographic (ECG) findings in an adult Japanese population were measured over a 5-year period, and the statistical relationships between these were evaluated. METHODS This was a longitudinal analysis in which data were collected on 353 subjects (135 men and 218 women) who had undergone general health checks in 1998 and 2003. RESULTS Data were examined by correlation coefficient and one-way analysis of covariance using repeated measurements. The correlation coefficient for BNP between 1998 and 2003 was 0.622 (P < 0.0001) for the men and 0.557 (P < 0.0001) for women. The changes in BNP over the same period were 13.71 +/- 26.06 (P < 0.0001) pg/ml in the men and 20.17 +/- 32.01 (P < 0.0001) pg/ml in the women. In 99 men and 145 women who had undergone ECG tests, with both normal and abnormal findings, visual inspections of changes in the ECG findings with respect to BNP changes were performed over the 5-year period. In men, both age and BNP significantly correlated with changes in ECG findings; however, in women, no significant correlation between BNP and changes in ECG findings was observed. CONCLUSIONS This regional longitudinal study revealed a gender difference in the relationship between long-term changes in BNP and ECG findings, suggesting that a 10 pg/ml or more increase in BNP in men over a 5-year period may a indicate worsening of cardiac function and the need for intervention.

Abstract
BACKGROUND Clinical markers to predict adverse outcome have not yet been established for patients with preserved left ventricular (LV) systolic function. The present study was designed to examine whether carboxy-terminal telopeptide of type I collagen (ICTP), a marker of collagen degradation, is useful for determining the prognosis of such patients. METHODS AND RESULTS Serum levels of ICTP were measured at admission in 156 consecutive patients hospitalized for chronic heart failure (CHF). Patients were divided into 2 groups based on the LV ejection fraction (LVEF): reduced LV systolic function group (LVEF <50%, n=92) and preserved LV systolic function group (LVEF > or =50%, n=64). In preserved LV systolic function group, cardiac event-free rates were significantly lower in high ICTP group than in low ICTP group (p<0.001). The area under the receiver operating characteristic curve of ICTP in the preserved LV systolic function group was markedly larger than that in the reduced LV systolic function group. Cox multivariate analysis also revealed that ICTP was an independent predictor of cardiac events in the preserved LV systolic function group. CONCLUSION Serum ICTP level is highly reliable for risk stratifying CHF patients with preserved LV systolic function.

Abstract
Brain natriuretic peptide (BNP) level is elevated in heart failure and reflects its severity. It is unknown why some patients have extremely high BNP levels. The authors retrospectively reviewed data on 179 consecutive patients whose BNP levels fell within one of several predetermined ranges: mild elevation, 500 to 1000 pg/mL (n=82); moderate elevation, 2000 to 3000 pg/mL (n=48); and high elevation, 4000 to 20,000 pg/mL (n=49). The statistical analysis was conducted with the unpaired t test and Pearson's correlation coefficient. Adjustments were made for age, sex, and serum creatinine level. Patients with moderate BNP elevation were more symptomatic and had more advanced structural and hemodynamic changes than did patients with lower BNP elevation. Characteristics of the high BNP level group did not differ from those of the moderate BNP level group. Serum creatinine level correlated with BNP level, but neither age nor sex did. High BNP level (4000-20,000 pg/mL) is determined more by renal dysfunction than by the severity of heart failure.

Abstract
BACKGROUND Acromegaly is associated with hypertrophic cardiomyopathy, hypertension and subsequent congestive heart failure. Impairment of cardiac function has also been associated with growth hormone deficiency (GHD). B-type natriuretic peptides (BNPs) have emerged as strong diagnostic and prognostic risk markers. They are cardioprotective hormones that compensate heart disease by promoting natriuresis and modulation of cardiac hypertrophy in response to volume expansion and ventricular wall stretch. OBJECTIVE To investigate N-terminal pro-BNP (NT-proBNP) in patients with GH disturbances before and after treatment, and in healthy gender- and age-matched controls. SUBJECTS AND METHODS Ten acromegalic patients (age 48 +/- 12 years) and 10 patients with GHD (age 41 +/- 14 years) were studied. None had symptoms or signs of cardiovascular disease except for hypertension. Serum NT-proBNP was measured before and 3, 6, 12 and 24 months after treatment. RESULTS Baseline NT-proBNP was lower in acromegalic patients [median (interquartile range) 24.3 (17.8-33.0) pg/ml] than in 20 healthy matched controls [57.9 (35.4-92.2) pg/ml; P < 0.001]. NT-proBNP increased during treatment (P = 0.002), concomitant with a decrease in IGF-I (P < 0.001). After 3 months of treatment NT-proBNP peaked, with a fourfold increase to 96.4 (57.8-113.2) pg/ml. NT-proBNP did not differ in patients with GHD compared with controls (P = 0.19), and did not change during treatment (P = 0.39). CONCLUSION Untreated patients with acromegaly had low NT-proBNP levels that increased fourfold after treatment. This is in contrast to other conditions with cardiac hypertrophy. Further studies are required to determine the significance of this novel finding in relation to acromegalic cardiac disease.

Abstract
B-Type natriuretic peptide (BNP) is elevated in states of increased ventricular wall stress. BNP is most commonly used to rule out congestive heart failure (CHF) in dyspneic patients. BNP levels are influenced by age, gender and, to a surprisingly large extent, by body mass index (BMI). In addition, it can be elevated in a wide variety of clinical settings with or without CHF. BNP is elevated in other cardiac disease states such as the acute coronary syndromes, diastolic dysfunction, atrial fibrillation (AF), amyloidosis, restrictive cardiomyopathy (RCM), and valvular heart disease. BNP is elevated in non-cardiac diseases such as pulmonary hypertension, chronic obstructive pulmonary disease, pulmonary embolism, and renal failure. BNP is also elevated in the setting of critical illness such as in acute decompensated CHF (ADHF) and sepsis. This variation across clinical settings has significant implications given the increasing frequency with which BNP testing is being performed. It is important for clinicians to understand how to appropriately interpret BNP in light of the comorbidities of individual patients to maximize its clinical utility. We will review the molecular biology and physiology of natriuretic peptides as well as the relevant literature on the utilization of BNP in CHF as well as in other important clinical situations, conditions that are commonly associated with CHF and or dyspnea.

Abstract
BACKGROUND Plasma B-type natriuretic peptide (BNP) levels depend on left ventricular (LV) filling pressures and correlate with the state of neurohormonal modulation in patients with congestive heart failure (CHF). In these subjects, therapy of decompensated CHF can determine acute changes in BNP levels. METHODS AND RESULTS We defined the sequential pattern of N-terminal (T) proBNP in elderly with decompensated CHF and preserved LV systolic function undergoing intensive unloading therapy, assessed the prevalence of patients who significantly reduced NTproBNP at the end of treatment, and verified the relations between changes in NTproBNP and ventricular filling pressures. NTproBNP was measured in 30 patients hospitalized for worsening CHF with LV ejection fraction >50% at admission and after 2 to 4 and 6 to 8 days from the start of treatment. Patients who exhibited a reduction in NTproBNP >35% from baseline to 8-day evaluation were defined as "responders." Twelve healthy subjects matched for age and sex were used as controls. NTproBNP was significantly higher in CHF patients than controls in all time points, to a greater extent in baseline evaluation (2982 [lower/upper quartile 1273/8146] versus 235 [150/280] pg/mL). A progressive, linear reduction of NTproBNP was detected in CHF patients during unloading. At Day 8, 18 patients (60%) resulted in "responders," whereas 12 (40%) were "nonresponders." The former could be predicted through higher pulmonary artery wedge pressure at baseline. Surprisingly, ventricular filling pressures similarly declined in responders and non responders. At Day 8, NTproBNP was yet 7-fold higher in CHF patients than controls. CONCLUSION Intensive unloading therapy is associated with a significant short-term reduction in NTproBNP in elderly with CHF and preserved LV systolic function. This behavior is progressive and linear during the first week and parallels a reduction in ventricular filling pressures which, however, does not differ between patients who significantly reduce NTproBNP and those who do not. Thus the short-term changes in NTproBNP during intensive unloading therapy in our patients do not depend only on the acute improvement in hemodynamic conditions.
