Wang P, Zhao Y, Wang D, Wang B, Liu H, Fu G, Tao L, Tian G. Relationship between waist-to-height ratio and heart failure outcome: A single-centre prospective cohort study. ESC Heart Fail 2024. [PMID: 39287135 DOI: 10.1002/ehf2.15029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2024] [Revised: 08/02/2024] [Accepted: 08/06/2024] [Indexed: 09/19/2024] Open
Abstract
AIMS This study sought to evaluate the correlation between waist-to-height ratio (WHtR) and heart failure (HF) outcomes across different ejection fraction (EF) categories. METHODS AND RESULTS A prospective cohort study was conducted at a comprehensive tertiary hospital in China. The participants were categorized by WHtR and EF quartiles. Outpatient or telephone follow-up occurred every 6 months after the diagnosis of heart failure. The primary endpoint was all-cause mortality at 48 months. Cox proportional hazard regression analyses were employed to evaluate the association between WHtR and all-cause mortality. Among 859 enrolled participants, 545 (63.4%) were male, and the mean age was 65.2 ± 11.1 years. After adjusting for age and sex, WHtR demonstrated a strong correlation with both BMI (correlation = 0.703, P = 0.000) and WHR (correlation = 0.609, P = 0.000). Individuals with a high WHtR (≥0.50) had a higher prevalence of hypertension (56.4% vs. 39.6%) and diabetes (26.5% vs. 13.7%), higher levels of TC (3.61 ± 1.55 vs. 3.36 ± 0.90 mmol/L), TG (1.40 ± 0.81 vs. 1.06 ± 0.59 mmol/L), and LDL-C (2.03 ± 0.85 vs. 1.86 ± 0.76 mmol/L) compared with patients with low WHtR (<0.50). NT-proBNP levels were inversely correlated with EF values in both low and high WHtR groups. A total of 149 (18.9%) patients died at the conclusion of the follow-up period. The incidence of all-cause and cardiovascular death was higher in the low WHtR group compared with the high WHtR group [HRs = 1.83 (1.30-2.58), 1.96 (1.34-2.88), respectively]. There was no significant difference in noncardiovascular mortality or rehospitalization rates between the two groups. Patients with HFrEF/low WHtR exhibited a markedly elevated risk of all-cause mortality [HR = 2.31; (95% CI: 1.24-4.30)], heart failure mortality [HR = 3.52; (95% CI: 2.92-8.80)], and noncardiovascular mortality [HR = 4.59; (95% CI: 1.19-17.76)] compared with patients with HFrEF/high WHtR. WHtR has a negligible effect on the risk of all-cause and cardiovascular mortality in heart failure patients with preserved EFs. CONCLUSIONS The obesity paradox, as delineated by WHtR, is observed in patients with HFrEF, yet absent in those with HFpEF.

Characteristics of heart failure with a preserved ejection fraction in black South African patients. IJC HEART & VASCULATURE 2024; 52:101408. [PMID: 38638536 PMCID: PMC11024654 DOI: 10.1016/j.ijcha.2024.101408] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 03/14/2024] [Accepted: 04/06/2024] [Indexed: 04/20/2024]
Abstract
Background Heart failure with a preserved ejection fraction (HFpEF) is common in the elderly (≥75 years) and associated with arterial stiffness. The mean age of HFpEF presentation is lower (40-55 years) in sub-Saharan Africa. No clinical study has been conducted on HFpEF in identifying and characterising this phenotype at a younger age, moreover in a South African black population where the risk of HFpEF is two times higher than in other ethnic groups. This study investigated the characteristics of HFpEF in a black South African population, the biochemical markers that predict HFpEF and cardiac structural changes in this HF phenotype. Methods Sixty-six participants with HFpEF and 213 controls were enrolled. All participants gave informed consent and completed a standardised questionnaire. Echocardiographic, anthropometric, central haemodynamic measurements, pulse wave velocity (PWV) and biomarker analysis were done. Results The mean age of HFpEF participants was 54.88 ± 13.51 years. Most of the participants (76 %) were between 20 and 64 years, while only 24 % were older. HFpEF participants were hypertensive, and more obese with increased incidence of alcohol consumption. PWV was increased in HFpEF (9.97 ± 2.78 m/s) when compared to participants without HFpEF (6.11 ± 2.18 m/s), p < 0.0001. There were no significant associations between central haemodynamic parameters, N-terminal pro B-type natriuretic peptide (NT-proBNP) (p = 0.9746), and galectin-3 (p = 0.2166). NT-proBNP, but not galectin-3, was associated with left ventricular hypertrophy (p = 0.0002) and left atrial diameter (p = 0.0005). Conclusion HFpEF in South Africa is predominant in obese young to middle-age individuals with arterial stiffness and who consume alcohol regularly. NT-proBNP could be used to diagnose HFpEF, however, should be interpreted with caution in populations with a high prevalence of obesity.

Abstract
Circulating biomarkers and imaging techniques provide independent and complementary information to guide management of heart failure (HF). This consensus document by the Heart Failure Association (HFA) of the European Society of Cardiology (ESC) presents current evidence-based indications relevant to integration of imaging techniques and biomarkers in HF. The document first focuses on application of circulating biomarkers together with imaging findings, in the broad domains of screening, diagnosis, risk stratification, guidance of treatment and monitoring, and then discusses specific challenging settings. In each section we crystallize clinically relevant recommendations and identify directions for future research. The target readership of this document includes cardiologists, internal medicine specialists and other clinicians dealing with HF patients.

Abstract
BACKGROUND NT-proBNP is a biomarker of cardiovascular disease (CVD). Little is known about the heritability and genetic variants associated with NT-proBNP. Therefore, we estimated the heritability of and examined genetic associations of SNPs in the BNP gene region with circulating NT-proBNP and prevalent CVD in 4,331 participants from the Long Life Family Study (LLFS). METHODS AND RESULTS Genotypes of 10 SNPs from the NPPB and NPPA regions that encode BNP and A-type natriuretic peptide, respectively, were tested for association with NT-proBNP and prevalent cardiovascular disease and risk factors. We performed analyses using the Sequential Oligogenic Linkage Analysis (SOLAR) program to account for family relatedness, and adjusted all models for age, sex, and field center. The mean age of the LLFS was 69.8 years (range 24-110) with 55.4% females. NT-proBNP was significantly heritable (h2 = 0.21; P = 4x10-14), and the minor alleles of rs632793 (p<0.001) and rs41300100 (p = 0.05) were independently associated with higher serum NT-proBNP levels. Additionally, the minor allele of rs632793 was significantly and consistently associated with lower prevalent CVD, including blood pressures, independent of NT-proBNP level (all P<0.05). Results for prevalent CVD, but not NT-proBNP levels, showed significant interaction by familial generation. CONCLUSION In this family-based study of subjects with exceptional longevity, we identified several allelic variants in the BNP gene region associated with NT-pro-BNP levels and prevalent CVD.

Abstract
Abstract
In recent years, the formulation of some immunoassays with high-sensitivity analytical performance allowed the accurate measurement of cardiac troponin I (cTnI) and T (cTnT) levels in reference subjects. Several studies have demonstrated the association between the risk of major cardiovascular events and cardiac troponin concentrations even for biomarker values within the reference intervals. High-sensitivity cTnI and cTnT methods (hs-cTn) enable to monitor myocardial renewal and remodelling, and to promptly identify patients at highest risk ofheart failure. An early and effective treatment of individuals at higher cardiovascular risk may revert the initial myocardial remodelling and slow down heart failure progression. Specific clinical trials should be carried out to demonstrate the efficacy and efficiency of the general population screening by means of cost-benefit analysis, in order to better identify individuals at higher risk for heart failure (HF) progression with hs-cTn methods.

Abstract
BACKGROUND Chronic exposure to biomass fuel smoke has been implicated in the development of pulmonary hypertension and right ventricular pressure/volume overload through activation of inflammation, increase in vascular resistance, and endothelial dysfunction. We sought to compare N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) and echocardiography-derived pulmonary artery systolic pressure (PASP) levels in a high-altitude population-based study in Peru with and without chronic exposure to biomass fuel smoke. METHODS NT-pro-BNP levels were measured in 519 adults (275 with and 244 without chronic exposure to biomass fuel smoke). Participants answered sociodemographics and clinical history questionnaires, underwent a clinical examination and blood testing for cardiopulmonary biomarkers. PASP was measured in a subgroup of 153 (31%) subjects. RESULTS The study group consisted of 280 men (54%) and 239 women (46%). Average age was 56 years and average body mass index was 27 kg/m(2). In multivariable analysis, there was no association between chronic exposure to biomass fuel smoke and NT-pro-BNP (P = .31) or PASP (P = .31). In the subgroup in which both NT-pro-BNP levels and PASP were measured, there was strong evidence of an association between these two variables (ρ = 0.24, 95% CI 0.09-0.39; P = .003). We found that age, high sensitivity C-reactive protein, being male, and systolic blood pressure were positively associated with NT-pro-BNP levels whereas body mass index, low-density/high-density lipoprotein ratio, and Homeostasis Model of Assessment-Insulin Resistance were negatively associated (all P ≤ .02). CONCLUSIONS In this population-based study in a high-altitude setting, neither NT-pro-BNP levels nor echocardiography-derived PASP were associated with chronic exposure to biomass fuel smoke.

Abstract
BACKGROUND Among people with type 2 diabetes the relationship between central obesity and cardiovascular mortality has not been definitely assessed. Moreover, NT-proBNP is negatively associated with central obesity, but no study has examined their combined effect on survival. We have examined these issues in a well-characterized population-based cohort. METHODS AND FINDINGS Survival data of 2272 diabetic people recruited in 2000 who had no other chronic disease have been updated to 31 December 2006. NT-proBNP was measured in a subgroup of 1690 patients. Cox proportional hazards modeling was employed to estimate the independent associations between cardiovascular and all-cause mortality and waist circumference. Mean age was 67.9 years, 49.3% were men. Both age and NT-proBNP were negatively correlated with waist circumference (r = -0.11, p<0.001 and r = -0.07, p = 0.002). Out of 2272 subjects, 520 deaths (221 for CV mortality) occurred during a median follow-up of 5.4 years. Central obesity was not associated with CV mortality (hazard ratio, HR, adjusted for age, sex, diabetes duration, 1.14, 95% CI 0.86-1.52). NTproBNP was a negative confounder and age a strong modifier of this relationship (p for interaction<0.001): age<70 years, fully adjusted model HR = 3.52 (1.17-10.57) and age ≥70 years, HR = 0.80 (0.46-1.40). Respective HRs for all-cause mortality were 1.86 (1.03-3.32) and 0.73 (0.51-1.04). CONCLUSIONS In diabetic people aged 70 years and lower, central obesity was independently associated with increased cardiovascular mortality, independently of the negative effect of NT-proBNP. In contrast, no effect on 6-years survival was evident in diabetic people who have yet survived up to 70 years.

Abstract
OBJECTIVE Depression is a common condition in obese women that can result in severe impairment of their physical and social functioning. A deficiency of brain-derived neurotrophic factor (BDNF) is involved in the mechanism of depression. The aim of this study is to investigate whether BDNF levels differ between obese female patients and healthy controls and whether BDNF levels alter with affective states in depressive obese women. METHODS The study group included 40 obese, 40 preobese, and 40 normal weight women. BDNF levels were measured with an enzyme-linked immunosorbent assay in patient and control groups. For identifying the depression and anxiety status, Beck Depression/Anxiety Inventories were used; and for the evaluation of cognitive functions, the mini-mental state examination was used. RESULTS BDNF levels were significantly lower in obese patients compared to the control group (P<0.01). BDNF levels were significantly lower in obese patients with depression compared to the obese patients without depression (P<0.05). The Beck Depression Inventory showed a negative correlation with BDNF (r=-0.044; P<0.01) and a positive correlation with the Beck Anxiety Inventory (r=0.643; P<0.001), vitamin B12 levels (r=0.023; P<0.001), and insulin levels (r=0.257; P<0.05) in obese patients. When receiver operating characteristic curve analysis was used to analyze the suitability of BDNF to identify depression in obese women, the area under the curve for BDNF, 0.756, was found to be significant (P=0.025). BDNF levels lower than 70.2 pg/mL were associated with a higher prevalence of depressive symptoms. CONCLUSION The results of our study suggest that the decrease in BDNF levels can be used as a marker for depression diagnosis in obese patients.

Abstract
Water and sodium retention precedes the development of high blood pressure (BP) and explains a compensatory rise in B-type natriuretic peptide (BNP) concentrations. It is unclear whether BNP concentrations antedate the BP progression. We hypothesized that higher BNP concentrations in our African American cohort will be associated with longitudinal increases in BP, progression of BP stage, and incident hypertension. Our study sample consisted of 888 normotensive (based on BP at examination 1 [2000-2004]) participants of the Jackson Heart Study (mean age, 47±12 years; 61% women). We examined the relation of BNP concentrations at the baseline examination to change in systolic and diastolic BPs, BP progression (an increase by 1 BP stage as defined by THE sixth report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure) and incident hypertension by examination 2 (2005-2008) adjusting for baseline BP stages, systolic and diastolic BPS, traditional risk factors, and echocardiographic left ventricular mass. Over a median follow-up period of 5.0±0.8 years, 36.9% progressed to a higher BP stage and 19.3% developed hypertension. In multivariable regression models, higher log-BNP concentrations at examination 1 were significantly and positively associated with changes in systolic and diastolic BPs (P<0.05 for both). Baseline log-BNP was significantly associated with BP progression (P=0.046). Every SD increase in baseline log BNP was associated with a 12% increased risk of BP progression. Log-BNP was not significantly associated with incident hypertension (P=0.12). In our community-based sample of African Americans, higher BNP concentrations predicted a longitudinal increase in systolic and diastolic BPs and progression of BP stage.

Abstract
High levels of B-type natriuretic peptide in cancer patients are poorly studied. Previously published data suggest that they are not related to fluid overload and are encountered mostly in solid cancers. The authors investigated the distribution of amino terminal pro-brain natriuretic peptide (NT-proBNP) between hematologic and solid organ malignancies and the relationship of NT-proBNP with volume status in oncologic patients. A total of 145 consecutive patients with at least one occurrence of NT-proBNP exceeding the upper normal range 10-fold were identified. The authors retrospectively reviewed their records including clinical, laboratory, and radiological data and echocardiograms. More than 70% of patients had hematologic malignancies. Patients with NT-proBNP >50,000 pg/mL had only hematologic malignancies, primarily multiple myeloma. There was no association between M-spike proteins and NT-proBNP. About 80% of patients had signs of fluid overload. The magnitude of NT-proBNP elevation was similar between those with and without heart failure or volume overload, as well as with solid cancers vs hematologic malignancies. Contrary to prior reports, it was found that very high NT-proBNP in cancer patients is usually encountered in the context of fluid overload and most often in hematologic malignancies.

Abstract
Look AHEAD (Action for Health in Diabetes) is a randomized trial determining whether intensive lifestyle intervention (ILI) aimed at long-term weight loss and increased physical fitness reduces cardiovascular morbidity and mortality in overweight and obese individuals with type 2 diabetes compared to control (diabetes support and education, DSE). We investigated the correlates of N-terminal pro-brain natriuretic peptide (NT-proBNP), a biomarker associated with heart failure (HF) risk, in a subsample from 15 of 16 participating centers and tested the hypothesis that ILI decreased NT-proBNP levels. Baseline and 1-year blood samples were assayed for NT-proBNP in a random sample of 1,500 without, and all 628 with, self-reported baseline CVD (cardiovascular disease) (N = 2,128). Linear models were used to assess relationships that log-transformed NT-proBNP had with CVD risk factors at baseline and that 1-year changes in NT-proBNP had with intervention assignment. At baseline, the mean (s.d.) age, BMI, and hemoglobin A(1c) (HbA(1c)) were 59.6 (6.8) years, 36.0 kg/m(2) (5.8), and 7.2% (1.1), respectively. Baseline geometric mean NT-proBNP was not different by condition (ILI 53.3 vs. DSE 51.5, P = 0.45), was not associated with BMI, and was inversely associated with HbA(1c). At 1 year, ILI participants achieved an average weight loss of 8.3% compared to 0.7% in DSE. At 1 year, NT-proBNP levels increased to a greater extent in the intervention arm (ILI +21.3% vs. DSE +14.2%, P = 0.046). The increased NT-proBNP associated with ILI was correlated with changes in HbA(1c), BMI, and body composition. In conclusion, among overweight and obese persons with diabetes, an ILI that reduced weight was associated with an increased NT-proBNP.
