AbstractBrain natriuretic peptide (BNP) is increased in patients with heart failure due to myocardial infarction and cardiac hypertrophy, in proportion to the severity of left ventricular dysfunction. The aims of this study were to clarify the clinical features of BNP and to determine the diagnostic value of BNP for mass screening.The subjects were 818 office workers (565 males and 253 females; mean age 47 ± 12 years) who participated in a 1996 routine health check at Kansai University All individuals were examined for blood pressure, serological findings, ECG and plasma BNP level. Thirty-three males underwent 2-D echocardiography. Plasma BNP levels were measured using IRMA (immunoradiometric assay).The results were as follows: (1) BNP levels in females were higher than those in males for healthy subjects (N = 551), in each age group from 20 to 60 years. (2) BNP levels increased with age. (3) There were significant correlations between BNP level and systolic blood pressure and creatinine level. (4) There were significant differences in BNP level between the hypertensive groups with and without hypertensive ECG changes and the age-matched healthy control group. (5) Marked correlations were observed between BNP level and left ventricular wall thickness, fractional shortening, deceleration time and peak early filling velocity. (6) A BNP cut-off-point of 25 pg/ml was best for detecting LV diastolic dysfunction and LV hypertrophy. Measurement of BNP is useful for detecting asymptomatic heart failure in the general population, and is a clinical marker useful in preventing symptomatic heart failure.

Background: Apelin is a regulatory vasoactive peptide, which plays a pivotal role in adverse cardiac remodeling and heart failure (HF) with reduced ejection fraction. The purpose of the study was to investigate whether serum levels of apelin is associated with HF with preserved election fraction (HFpEF) in patients with T2DM. Methods: The study retrospectively involved 101 T2DM patients aged 41 to 62 years (48 patients with HFpEF and 28 non-HFpEF patients). The healthy control group consisted of 25 individuals with matched age and sex. Data collection included demographic and anthropometric information, hemodynamic performances and biomarkers of the disease. Transthoracic B-mode echocardiography, Doppler and TDI were performed at baseline. Serum levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) and apelin were measured by ELISA in all patients at the study entry. Results: Unadjusted multivariate logistic model yielded the only apelin to NT-proBNP ratio (OR = 1.44; p = 0.001), BMI > 34 кг/м2 (OR = 1.07; p = 0.036), NT-proBNP > 458 pmol/mL (OR = 1.17; p = 0.042), LAVI > 34 mL/m2 (OR = 1.06; p = 0.042) and E/e’ > 11 (OR = 1.04; p = 0.044) remained to be strong predictors for HFpEF. After obesity adjustment, multivariate logistic regression showed that the apelin to NT-proBNP ratio < 0.82 × 10−2 units remained sole independent predictor for HFpEF (OR = 1.44; 95% CI: 1.18–2.77; p = 0.001) HFpEF in T2DM patients. In conclusion, we found that apelin to NT-proBNP ratio < 0.82 × 10−2 units better predicted HFpEF in T2DM patients than apelin and NT-proBNP alone. This finding could open new approach for CV risk stratification of T2DM at higher risk of HF.

The purpose of this study was to clarify whether the secretions of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) are pulsatile in patients with chronic heart failure (CHF), and whether the rhythmic oscillations for ANP and BNP are abnormal in patients with CHF. Several reports have shown that ANP and especially BNP are valuable indicators of the prognosis in CHF. Previously, a pulsatile secretion has been described for ANP and BNP in healthy humans and for ANP in CHF patients. More information about the secretion pattern of BNP in heart failure is necessary to increase the clinical usefulness of BNP in patients with CHF. Patients with left ventricular systolic dysfunction and CHF (n = 12) and controls (n = 12) were investigated. Plasma ANP and BNP levels were determined every 2min during a 2-h period by radioimmunoassay and analysed for pulsatile behaviour by Fourier transformation. All patients and controls had significant rhythmic oscillations in plasma ANP levels, and 11 patients with CHF and 10 controls had significant rhythmic oscillations in plasma BNP levels. The amplitude of the main frequency was considerably higher in patients with CHF than in controls (ANP: CHF, 4.76pmol/l; controls, 0.75pmol/l; P<0.01. BNP: CHF, 3.24pmol/l; controls, 0.23pmol/l; P<0.001; all values are medians), but the main frequency did not differ significantly between the group with CHF and the control group for either ANP or BNP. Patients with CHF demonstrate pulsatile secretion of ANP and BNP with a much higher absolute amplitude, but with the same main frequency as healthy subjects.

INTRODUCTION: Congestive Heart Failure is a complex physiological syndrome caused from structural or functional alterations to the myocardium. Lactate is produced by anaerobic metabolism and is secreted by the Brain-Natriuretic peptide heart ventricles in response to left ventricular stretching or wall tension. AIM: The aim of the study was to evaluate Brain-Natriuretic Peptide, Lactate levels and Blood pressure in Congestive Heart Failure patients and compared them with healthy individual. MATERIALS AND METHODS: Total 80 participants who fullled the inclusion and exclusion criteria were enrolled in the study. They were divided into two group i.e., case and control group. Case group included 40 patients of Congestive Heart Failure, age between 18-65 years and control group comprised of 40 healthy individuals with similar age range. Blood sample were drawn and analyzed for the evaluation of Serum lactate and Brain-Natriuretic Peptide. Blood Pressure was also measured in both the groups. RESULT: The present study has demonstrated that the level of Brain-Natriuretic Peptide and lactate were signicantly high in Congestive heart failure patients when compared with control group. Systolic and Diastolic blood pressure were also higher among patients group. CONCLUSION: The results of the study suggested that the levels of Lactate and Brain-Natriuretic Peptide were high in Congestive heart failure patients when compared with healthy individual. Systolic and Diastolic blood pressure were also higher among patients group. Elevated lactate and Brain-Natriuretic Peptide level can be recommended as useful indicator of poor prognosis and hence can be helpful in early identication of patients at risk.

Objective This study was performed to determine whether a dual-biomarker approach using N-terminal prohormone of brain natriuretic peptide (NT-proBNP) and galectin-3 optimizes the diagnosis and risk stratification of acute cardiac dyspnea. Atypical clinical manifestations and overlapping pathologies require objective and effective diagnostic methods to avoid treatment delays. Methods This prospective observational study included 208 patients who presented to the emergency department for acute dyspnea. NT-proBNP and galectin-3 were measured upon admission. The patients were divided into two groups according to the etiology of their clinical manifestations: cardiac and non-cardiac dyspnea. The patients’ New York Heart Association functional class, left ventricular ejection fraction, and discharge status were assessed. Results Diagnostic criteria for acute heart failure were fulfilled in 61.1% of the patients. NT-proBNP and galectin-3 were strongly and significantly correlated. Receiver operating characteristic analysis revealed similar areas under the curve for both markers in the entire group of patients as well as in the high-risk subsets of patients. Conclusions The diagnostic performance of NT-proBNP and galectin-3 is comparable for both the total population and high-risk subsets. Galectin-3 adds diagnostic value to the conventional NT-proBNP in patients with acute cardiac dyspnea, and its utility is of major interest in uncertain clinical situations.

Background and Objective: Surgical treatment of severe secondary ischemic mitral regurgitation (IMR) may improve symptoms and functional capacity, however there are few data on its effect on long-on the evolution of heart failure. Time-course changes in brain natriuretic peptide (BNP) are a good marker of the heart failure status and outcomes. We investigated the association between the exercise stress echocardiographic (ESE) parameters and the changes in brain natriuretic peptide (BNP) following surgery for secondary IMR. Methods: We prospectively analyzed data on 50 patients (median age: 67, 61-64 y; EF: 35, 34-40%), undergoing mitral valve annuloplasty or replacement and coronary artery bypass graft (CABG). A valve annuloplasty with undersized ring was performed in 20 patients (40%) and a replacement in 30 (60%). A six minute walking test (6-MWT), BNP levels and ESE were performed at 1 year and at median follow-up (FU) of 6 years (4-7). Results: BNP level was: 388 (329-441) pg/ml before surgery, 175 (142-743) pg/ml at 1 y, and 123 (100-979) pg/ml at last FU (p=0.2). The relative changes of BNP from baseline to last FU significantly correlated with exercise tricuspid annulus plane systolic excursion (TAPSE) at last FU (r= -0.7, p<0.001), with preoperative and FU exercise LVEF, respectively ( r=-0.7 p= 0.01) (r=-0.93, p<0.001).On multivariable analysis, preoperative exercise EF was strongly and independently associated with independent BNP levels at last FU and with the changes in BNP from baseline to last FU. Conclusions: Despite surgical treatment of severe secondary IMR, BNP levels progressively increased over time in nearly 50% of the patients. Lower preoperative and 1-year FU exercise-stress EF was associated with increased levels of BNP during FU..
