A preliminary study of the value of N-terminal pro-B-type natriuretic peptide in patients with end-stage heart failure implanted with magnetic fluid suspended left ventricular assist devices / 中华检验医学杂志

Objective:To investigate the changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) and its role in predicting major adverse cardiac events (MACEs) in patients with end-stage heart failure (ESHF) before and after implanted a HeartCon left ventricular assist device (LVAD).Methods:The retrospective study included 30 ESHF patients [23 males and 7 females, aged 54.5 (40.8, 60.0) years], who were admitted to TEDA International Cardiovascular Disease Hospital from September 15, 2020 to June 20, 2023 to receive treatment with HeartCon LVAD implantation. Their clinical data were analyzed and NT-proBNP concentrations in their blood samples were measured preoperatively and during the follow-up period. Patients were followed regularly and MACEs, including cardiac death and rehospitalization for right heart failure, were recorded within 6 months of discharge; Logistic regression was used for prognostic analysis, and Receiver Operator Characteristic (ROC) curves were used to assess the adjunctive diagnostic value of NT-proBNP for poor prognosis in LVAD patients. The cut-off values for diagnosing poor prognosis by NT-proBNP were divided into two groups, and survival analysis was performed by Kaplan-Meier and tested by log rank; Cox regression was performed to analyze whether high levels of NT-proBNP at 6 months of follow-up wsa a risk factor for poor prognosis in patients with LVAD.Results:The median preoperative NT-proBNP level in 30 ESHF patients successfully implanted with HeartCon LVADs was 3 251.0 (1 544.5, 6 401.5) pg/ml. It decreased significantly 7 days postoperatively (3 251.0 vs. 1 815.0 pg/ml, P<0.05), and then the decreasing trend slowed. It decreased to 1 182.0 (620.0, 3 385.3) pg/ml on the 90th post-operative day. The preoperative NT-proBNP>3 251.0 pg/ml group had a longer postoperative hospital stay (47 d vs 33 d, Z=-2.138, P=0.032). Multivariate logistic regression analysis, only NT-proBNP at 7 days postoperatively was found to predict poor prognosis in LVAD patients, with an OR of 1.001 ( P=0.01); ROC curves were analyzed for the adjunctive diagnostic value of 7-day postoperative NT-proBNP levels for poor prognosis (cut-off value of 2 083.0 pg/ml), with an AUC of 0.833 ( P=0.002); The Kaplan-Meier survival analysis showed that the time to MACEs within 6 months was significantly shorter in the group with NT-proBNP>2 083.0 pg/mL on postoperative day 7 than in the group with NT-proBNP≤2 083.0 pg/ml (3.538±0.689 vs. 5.471±0.323 months, P=0.004); Cox regression analysis showed that the risk of MACEs was 4.25 times higher in the 7-day postoperative NT-proBNP>2 083.0 pg/ml group than in the NT-proBNP≤2 083.0 pg/ml group ( HR=4.25, P=0.035). Conclusions:The higher the preoperative NT-proBNP level, the longer the postoperative hospital stay in HeartCon LVAD patients. NT-proBNP levels decrease most significantly on postoperative day 7 and is a risk factor for MACEs. It may be used as a prognostic predictor in ESHF patients with implanted LVADs.

Introduction: In hospitalized patients, atrial fibrillation is the most common arrhythmia, and leading cause of cardio-embolic stroke. Objective: To evaluate the association between N-terminal b-type natriuretic peptide pro (NT-proBNP) and left atrial appendage thrombus in persistent atrial fibrillation patients. Methods: A cross-sectional study, enrolled 139 patients with persistent non-valvular atrial fibrillation. Transthoracic and trans-esophageal echocardiographs were performed in all patients. Results: Mean age was 70.5 ( 10.6 years, 80.6% male. In patients with LAAT, NT-proBNP was positively correlated with left ventricular end diastolic diameter (LVEDD) (r=0.345), left ventricular end-systolic diameter (LVEDS) (r= 0.449), E/e' (r=0.445), and left atrial spontaneous echo contrast (LA SEC) (r=0.478), and negatively correlated with left ventricular ejection fraction (LVEF) (r=-0.473), left atrial strain (r= -0.301), strain rate (r= -0.283), and e'(r= -0.458). In patients without LAAT, NT-proBNP was positively correlated with LVEDD (r= 0.333), LVESD (r= 0.358), E (r= 0.318), E/e' (r= 0.411), left atrial volume index (LAVI) (r= 0.421), and negatively correlated with LVEF (r= -0.307). Plasma NT-proBNP (> 1279 pg/mL) could be used to predict LAAT (AUC= 0.639; Se= 67.7 percent, Sp= 60.2 percent). In patients with ejection fraction > 50 percent, the cutoff value of NT-proBNP to predict LAAT was 1325 pg/mL (AUC= 0.572; Se= 57.9 percent , Sp= 78.3 percent). Multiple logistic regression analysis showed that prior stroke, E/e' index, and NT-proBNP correlated with LAAT (r= 0.887; p< 0.001; r= -0.092, p= 0.035 and 0.022; p= 0.004, respectively). Conclusion: Plasma NT-proBNP levels and E/e' index are associated with LAAT in patients with persistent atrial fibrillation(AU)

NT-proBNP plasmático (>1279 pg/mL) podría usarse para predecir LAAT (AUC=0,639; Se=67,7 por ciento, Sp=60,2 por ciento). En pacientes con fracción de eyección >50 por ciento; valor de corte de NT-proBNP para predecir LAAT fue 1325 pg/mL (AUC=0,572; Se=57,9 por ciento, Sp=78,3 por ciento). Según regresión logística múltiple, el accidente cerebrovascular previo, el índice E/e' y NT-proBNP se correlacionaron con LAAT (r=0,887; p<0,001; r=0,092, p=0,035 y 0,022; p=0,004, respectivamente). Conclusiones: Los niveles plasmáticos de NT-proBNP y el índice E/e' se asocian con el OAI en pacientes con FA persistente(AU)

Evaluation of Clinical, Demographic, and Biochemical Profiles of Trinidadian Patients Undergoing Coronary Angiography

Background: Trinidad and Tobago ranks number 45 in the world for total deaths due to coronary heart disease. Predictive tests for coronary angiographic results set the basis for earlier monitoring of the disease before additional complications become obvious. Aims and Methods?This study aimed to evaluate the anthropometric and biochemical parameters of 124 patients with suspected coronary artery disease (CAD) in Trinidad and how these parameters correlate to the findings at angiography. Results?The biochemical parameters showed statistically significant correlations with CAD severity by Spearman's rank-order correlation. Two clinical parameters showed significant associations with CAD severity—ethnicity (?2 (4)?=?12.925, p?=?0.012) and presence of type 2 diabetes at baseline (?2 (4)?=?21.483, p?<?0.001). Conclusion?Biochemical parameters such as fasting blood sugar, N-terminal pro B-type natriuretic peptide, creatinine, and hemoglobin A1c were well correlated and well associated with the severity of CAD after diagnosis by the process of coronary angiography. Hence, these factors can be taken into consideration to predict the severity of CAD.

Introduction: Heart failure (HF) is a prevalent clinical syndrome worldwide, which benefits from a multidisciplinary approach, but its outpatient follow-up remains a challenge. The diagnostic and prognostic utility of NT-proBNP is supported by current evidence, but its use in monitoring has not yet been defined. The present study sought to determine whether the variation over time in the value of NT-proBNP was related to changes in the pharmacological treatment of outpatients with HF and reduced left ventricular ejection fraction (LVEF ≤ 40%) in a multidisciplinary heart failure unit. (MHFU). Methodology: Retrospective cohort study of patients, who met the inclusion criteria: 2 or more quantifications of NT-proBNP in 12 months and a minimum follow-up of 2 years between 2013 and 2017. Results: Of 566 members of the MHFU active cohort, 107 met the inclusion criteria; most men (58%), median age 63 years (Q1;Q3: 55.9;71.2), the main comorbidity was arterial hypertension (71%). The etiology of HF was non-ischemic in 56% of the population, and 50% had a functional class - NYHA I. Median baseline NT-proBNP was 698 pg/ml (Q1;Q3: (218;1564), with median baseline LVEF of 30% (Q1;Q3: 27;40). In 55% of the patients, the variation in the NT-proBNP value during follow-up was related to changes in pharmacological treatment. Conclusions: In half of the population of our cohort, it was shown that NT-proBNP values were related to changes in pharmacological treatment, regardless of the clinical situation.

The trajectory of NT-proBNP within two years after percutaneous coronary intervention for stable coronary artery disease and its predictive significance in prognosis: A longitudinal cohort study / 中华检验医学杂志

Objective:This study aimed to investigate the predictive value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) trajectory on future major adverse cardiovascular events (MACE) in patients with stable coronary artery disease (SCAD) after percutaneous coronary intervention (PCI).Methods:A retrospective cohort study was conducted on SCAD patients admitted to the Department of Cardiology at Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, from January 2013 to December 2021. A total of 828 subjects were enrolled, comprising 592 males and 236 females, with an average age of (66.44±11.71) years. SCAD patients post-percutaneous coronary intervention (PCI) were stratified into three NT-proBNP trajectory groups: T1 Low-Low (219 cases), T2 Medium-Low (363 cases), and T3 High-High (246 cases). The median follow-up time was 2.1 years, and the maximum follow-up time was 9 years. The primary clinical endpoint event was MACE. The NT-proBNP concentration in patients′ serum was measured using enzyme-linked fluorescent assay, and different trajectory groups were determined using latent class trajectory modeling. The association between NT-proBNP trajectory and occurrence of MACE in SCAD patients was evaluated using Kaplan-Meier survival curves and multivariable Cox proportional hazards regression models.Results:A total of 67 (8.1%) major adverse cardiovascular events occurred, including 43 cases (5.2%) of all-cause mortality, 13 cases (1.6%) of heart failure death, 9 cases (1.1%) of non-fatal myocardial infarction, and 15 cases (1.8%) of non-fatal stroke. Kaplan-Meier survival curve analysis showed significant differences in survival rates among T1, T2, and T3 groups of SCAD patients for MACE, all-cause mortality, and heart failure death (all P<0.001). In the multivariable Cox regression analysis, the risk of MACE occurrence for patients in the T2 group and T3 group was 1.708 times (95% CI 0.72-4.05) and 3.842 times (95% CI 1.625-9.081) compared to the T1 group, respectively. Moreover, a statistically significant linear trend was observed for the risk of MACE occurrence across trajectory groups ( P<0.001). Conclusions:NT-proBNP trajectory groups after PCI in SCAD patients are strongly associated with the risk of MACE occurrence and can serve as an independent predictor for MACE. Dynamic monitoring of NT-proBNP during follow-up to obtain longitudinal trajectories helps identify high-risk SCAD patients and implement timely effective intervention measures.

2D Echocardiographic Findings, NT-ProBNP Levels, and Outcomes in Dyspnoeic Patients: Results from the Pro-BNP Investigation of Dyspnoea in the Emergency Department- a Single Centre Experience

Background: Dyspnoeic in the emergency department with multiple co-morbidities is a diagnostic challenge. Approximately 15-20% of acute dyspneic in the Emergency Department due to ADHF (acute decompensated heart failure) are misdiagnosed. B-type peptide (BNP) and its amino-terminal fragment (NT-proBNP) accurately identify HF in dyspnoeic patients. In the general population with dyspnoea, plasma pro-BNP concentrations are increased in left ventricular dilatation, hypertrophy, systolic dysfunction, or diastolic dysfunction but are unaffected by pulmonary dysfunction. Aims and Objectives: To study the relation between NT pro-BNP & echocardiographic findings in acute dyspnoeic patients, and the relation between NT pro-BNP and In-hospital Mortality. Materials and Methods: Source of data- Patients admitted to the Emergency Room or cardiac intensive care unit with a history of acute dyspnea in a tertiary cardiac care center in south India, meeting inclusion & exclusion criteria, were studied. Results: The study population is predominantly constituted of the elderly population. The most common co-morbid condition was hypertension. The present study uses an NT pro BNP level of 900pg/ml as the cut-off level. 78 patients were positive for the test. Echocardiography showed that 58% had LV systolic dysfunction, 60% had diastolic dysfunction. 42 patients had EF >55%, 10 patients between 55-45%, 33 patients between 44-30% and 15 patients had EF < 30%. Mortality rate was 6% in the whole study population. However, Mortality was seen in only NT pro-BNP positive group it was not statistically significant (p=0.46). Conclusions: NT pro-BNP correlates well with the worsening of LV systolic function; as the EF decreases, NT pro-BNP increases. Increase in NT pro-BNP levels has to be interpreted in the clinical context, and it is not a substitute for echocardiography for assessing cardiac abnormalities and dysfunction.

Clinical value of sST2 in replacement of NT-proBNP in cardiac function evaluation in renal failure patients after cardiac surgery / 中国胸心血管外科临床杂志

@#Objective    To explore the clinical value of soluble suppression of tumorigenesis-2 (sST2) in replacement of N-terminal fragment of the brain natriuretic peptide precursor (NT-proBNP) in cardiac function evaluation in renal failure patients after cardiac surgery. Methods    Sixty patients with renal insufficiency after cardiac surgery from January 2019 to June 2019 were divided into a test group, including 34 males and 26 females, with an average age of 49-78 (63.3±4.5) years. Another 60 patients with normal renal function were divided into a control group, including 37 males and 23 females, with an average age of 53-77 (61.7±3.8) years. The perioperative left ventricular ejection fraction, cardiac troponin T, creatine kinase-MB, sST2 and NT-proBNP were compared. Results    In patients of the test group, the NT-proBNP level increased significantly during perioperative period, and the change range was different from other cardiac function indexes. The change of sST2 in perioperative period was similar to other cardiac function indexes, which could reflect the change degree of cardiac function after operation. Conclusion    sST2 is more important to reflect the change degree of cardiac function in patients with renal dysfunction after cardiac surgery than NT-proBNP.

BACKGROUND@#Epidemiological evidence has shown that serum N-terminal pro-brain natriuretic peptide (NT-proBNP) concentrations, a diagnostic biomarker for heart failure, are positively associated with cardiovascular risk. Since NT-proBNP in serum is excreted in urine, it is hypothesized that urinary NT-proBNP concentrations are correlated with serum concentrations and linked with cardiovascular risk in the general population.@*METHODS@#A total of 3060 community-dwelling residents aged ≥ 40 years without history of cardiovascular disease (CVD) were followed up for a median of 8.3 years (2007-2015). Serum and urinary concentrations of NT-proBNP at baseline were compared. The hazard ratios (HRs) and their 95% confidence intervals (CIs) for the association between NT-proBNP concentrations and the risk of developing CVD were computed using the Cox proportional hazards model.@*RESULTS@#The median values (interquartile ranges) of serum and urinary NT-proBNP concentrations at baseline were 56 (32-104) pg/mL and 20 (18-25) pg/mL, respectively. There was a strong quadratic correlation between the serum and urinary concentrations of NT-proBNP (coefficient of determination [R@*CONCLUSIONS@#The present study demonstrated that urinary NT-proBNP concentrations were well-correlated with serum concentrations and were positively associated with cardiovascular risk. Given that urine sampling is noninvasive and does not require specially trained personnel, urinary NT-proBNP concentrations have the potential to be an easy and useful biomarker for detecting people at higher cardiovascular risk.

Association of N-terminal-Pro-B-type Natriuretic Peptide with Localization of Thrombus and Clinical Outcome in Acute Pulmonary Embolism

Introduction: Pulmonary Embolism is a major health problemwhich is associated with significant mortality and morbidity. Itis a common and lethal condition. This study was undertakento find the association between NT-Pro-BNP levels and thelocalisation of thrombus in acute Pulmonary Embolism and toprognosticate the patients.Material and methods: Prospective study conducted ata tertiary care hospital.Thirty patients with PulmonaryEmbolism of various etiologies, confirmed with clinicalfeatures, laboratory investigations and imaging and fulfillingthe inclusion and exclusion criteria were included. Aftergetting informed consent, Blood samples for assessmentof NT-Pro-BNP levels were collected within 24 hours ofadmission.Results: In 19 patients, the thrombus was located centrally(in main pulmonary artery) whereas in 11 patients, thethrombus was located in the peripherally (in segmental andsubsegmental pulmonary arteries). 22 participants of thestudy had normal clinical outcome. 5 patients were morbid(oxygen dependant/ heart failure) whereas 3 patients died.Patients with central pulmonary embolus had higher NT-ProBNP levels whereas patients with pulmonary embolus in thesegmental or subsegmental pulmonary arteries had relativelyless NTPro-BNP levels. Patients with high NT-Pro-BNPlevels had complicated in-hospital course/ mortality whereas,patients with relatively lower NT-Pro-BNP had uncomplicatedin-hospital course.Conclusion: This study shows that higher NT-Pro-BNPlevels indicate higher probability of a more central locationof thrombus in pulmonary embolism and also right ventricularoverload. Also patients with higher NT-Pro-BNP levels had acomplicated in hospital course.

A Study to Assess the Role of NT-proBNP as a Marker of Cardiac Mortality In Hemodialysis Patients

Background: Increased N-terminal pro-B-type natriureticpeptide (NT-proBNP) concentrations are associated withcardiovascular mortality in hemodialysis patients. The presentstudy was conducted to assess the role of NT-proBNP as amarker of cardiovascular mortality in hemodialysis patients.Materials and Methods: NT-proBNP concentrations weremeasured in 50 prevalent hemodialysis patients to examine therisk of 90-days and 1-year mortality associated with baselineNT-pro BNP concentrations. Data was analyzed usingstandard descriptive statistics. Wilcoxon signed rank test andWelch two sample t-test were used in “R” commanderstatistical software.Results: The NT –pro BNP values at the entry into the study ofshort term i.e.90 days follow up death group were significantly(p value = 0.002647) high when compared to remaining livedialysis participants (n = 40). But the difference in NT –proBNP values at the entry into the study between death and liveparticipants was not statistically significant (p value = 0.7785)in long term i.e.1 year follow up participants. The difference inserum sodium at the time of entry, is statistically significant (p =0.03564), between live and dead groups at the end of shortterm follow up.Conclusion: Elevated NT-proBNP concentrations wereobserved in end-stage renal disease (ESRD) patients ondialysis at the entry of study and these values were associatedwith cardiac mortality in them. NT –pro BNP acts as a newermarker for cardiovascular risk in dialysis patients of ESRD.

@#Objective　To analyze the correlation between N-terminal pro-brain natriuretic peptide （NT-proBNP） and causes of acute cerebral infarction （ACI），severity of neurological deficits，prognosis，so as to provide reference for clinical intervention of ACI. Methods　Eighty patients with ACI who were admitted to the hospital from January 2017 to April 2019 were selected as ACI group. Forty healthy volunteers who underwent physical examination in the hospital during the same period were enrolled as control group. Blood samples were collected from two groups （within 24 h～48 h after onset in patients with ACI） to detect the NT-proBNP level. The etiological types in the trial of Org10172 in acute stroke treatment （TOAST） were recorded. National Institutes of Health Stroke Scale （NIHSS） was applied to evaluate severity of neurological deficits at admission. The modified Rinkin Scale （MRS） was applied to evaluate prognosis after 3 months of admission. Blood NT-proBNP levels in patients with different general data and cardiac indicators were compared. The multiple linear regression analysis was applied to analyze correlation between serum NT-proBNP level and TOAST etiological type，severity of neurological deficits，prognosis in ACI patients. Results　①The serum NT-proBNP in ACI patients was significantly higher than that in control group （P<0.001）. ②The serum NT-proBNP in ACI patients with type cardiac embolism （CE） as TOAST etiology typing，NIHSS score not lower than 7 points，mRS not lower than 3 points，with atrial fibrillation and thickened interventricular septum thickness （IST） were significantly higher than that in patients with non-CE type，NIHSS score within 0-6 points，mRS lower than 3 points，without atrial fibrillation and with normal IST （P<0.05）. ③The multiple linear regression analysis showed that type CE as TOAST etiology typing，severity of neurological deficits （NIHSS score） and mRS after 3 months of admission were closely related to serum NT-proBNP （P<0.05）. And Pearson correlation coefficients （r） were 0.822，0.545 and 0.452，respectively. Conclusion　After 24 h～48 h of onset in ACI patients，there is good correlation between serum NT-proBNP and etiology typing of TOAST，severity of neurological deficits，prognosis，which deserves clinical attention.
