N-Terminal pro-Brain Natriuretic Peptide (NT-pro BNP) has recently emerged as a promising biomarker for risk assessment in acute pulmonary embolism (PE). The aim of this study is to detect the in hospital prognostic value of NT-pro BNP in patients with acute (PE). Methods: This study included 64 patients diagnosed as (PE) with the mean age of 59.1 ± 16.5 years, 40 patients of them (62.5%) were male. All patients were subjected to 12 leads ECG. X-ray chest, laboratory tests including D-Dimer, troponin I, NT-pro BNP, Doppler ultrasound for the venous system of both lower limbs, Echocardiograhy and 64 multislices CT pulmonary angiography. Results: According to the admission level of NT-pro BNP our patients were divided into two groups: group I included 22 patients with normal NT-pro BNP (less than 300 pg/ml), and group II included 42 patients with elevated NT-pro BNP (more than or equal 300 pg/ml). Patients in group II were found to have a significantly higher incidence of heart failure (28.6% Vs 4.6%, p = 0.025), impaired kidney function (serum creatinine was 1.7 ± 0.6 Vs 1.1 ± 0.2, p = 0.018), tachypnea (85.7% Vs 54.5%, p = 0.006) and cardiogenic shock (26.2% Vs 0%, p = 0.014) but a significantly lower incidence of chest pain (21.4% Vs 45.5%, p = 0.04) and lower left ventricular ejection fraction (51.3% ± 16.9% Vs 67.3% ± 12.8%, p = 0.043) compared to group I. There were a significantly higher treatment with thrombolytic therapy (35.7% Vs 9.1%, p=0.021) and positive inotropics (35.71% Vs 4.55%, p = 0.006) in group II compared to group I. Also group II had a higher need for mechanical ventilation (26.12% Vs 4.55%, p = 0.04) and a longer in hospital stay (19.5 ± 10.3 Vs 5.3 ± 4.5, p = 0.001) than group I. The in hospital mortality was significantly higher in group II compared to group I (19.05% Vs 0.0%, p = 0.042). Conclusion: Elevated NT-pro BNP levels in patients with (PE) are associated with worse short term prognosis in terms of higher morbidity and mortality and it could be used as a valuable prognostic parameter and good indicator for the need of more aggressive therapy.展开更多

However,the role of short-term follow-up of NT-pro-BNP level remains unclear. Methods Three hundred and sixty-two patients diagnosed with AMI were retrospectively enrolled in this study from March 2014 to March 2017 in our center. Blood samples were obtained at initial admission and again within 1 month after hospital discharge. The univariate and multivariate cox regression analyses including significant covariables were performed on NT-pro-BNP level at admission,discharge,or change from admission to discharge to predict adverse cardiovascular events(MACE)as study endpoints. Results There were 211 cases in NT-pro-BNP decrease group,while 151 cases in NT-pro-BNP increase group. The median follow-up was 365 days(interquartile range[IQR],322-861 days). After adjusting the covariables in the multiple logistic regression analysis,follow-up NT-pro-BNP level was still a significant independent predictor for MACE(OR,1.395;95% CI,1.102-1.869,P=0.005). However,the initial NT-pro-BNP level or change of NT-pro-BNP level had no significant predictive value for MACE. Conclusions A short-term follow-up NT-pro-BNP level after hospital discharge is a powerful prognostic biomarker for MACE in patients with AMI.展开更多

Logistic regression and receiver operating characteristic(ROC) curve analyses were performed to determine whether red blood cell distribution width(RDW) was an independent risk factor for CCM risk. The relationships between RDW and Child-Pugh scores, Model for End-Stage Liver Disease(MELD) scores, and N-terminal pro-brain natriuretic peptide(NT-proBNP) were analyzed by Pearson correlation analysis.RESULTS A constant RDW increase was evident from Group Ⅰ to Group Ⅳ(12.54 ± 0.85, 13.29 ± 1.19, 14.30 ± 1.96, and 16.25 ± 2.13, respectively). Pearson correlation analysis showed that RDW was positively correlated with Child-Pugh scores(r = 0.642, P < 0.001), MELD scores(r = 0.592, P < 0.001), and NT-proBNP(r = 0.715, P < 0.001). Furthermore, between Group Ⅰ and Group Ⅱ, RDW was the only significant index(odds ratio: 2.175, 95% confidence interval [CI]: 1.549-3.054, P < 0.001), and it reached statistical significance when examined by ROC curve analysis(area under the curve: 0.686, 95%CI: 0.624-0.748, P < 0.001).CONCLUSION RDW can serve as an effective and accessible clinical indicator for the prediction of diastolic dysfunction in CCM, in which a numerical value of more than 13.05% may indicate an increasing CCM risk.展开更多

文摘Background:Clinical assessment and treatment guidance for heart failure depends on a variety of biomarkers.The objective of this study was to investigate the prognostic predictive value of growth differentiation factor-15(GDF-15)and N-terminal prohormone of brain natriuretic peptide(NT-proBNP)in assessing hospitalized patients with acute heart failure(AHF).Methods:In total,260 patients who were admitted for AHF in the First Affiliated Hospital of Nanjing Medical University were enrolled from April 2012 to May 2016.Medical history and blood samples were collected within 24 h after the admission.The primary endpoint was the all-cause mortality within 1 year.The patients were divided into survival group and death group based on the endpoint.With established mortality risk factors and serum GDF-15 level,receiver-operator characteristic(ROC)analyses were performed.Cox regression analyses were used to further analyze the combination values of NT-proBNP and GDF-15.Results:Baseline GDF-15 and NT-proBNP were significantly higher amongst deceased than those in survivors(P<0.001).In ROC analyses,area under curve(AUC)for GDF-15 to predict 1-year mortality was 0.707(95%confidence interval[CI]:0.648–0.762,P<0.001),and for NT-proBNP was 0.682(95%CI:0.622–0.738,P<0.001).No statistically significant difference was found between the two markers(P=0.650).Based on the optimal cut-offs(GDF-15:4526.0 ng/L;NT-proBNP:1978.0 ng/L),the combination of GDF-15 and NT-proBNP increased AUC for 1-year mortality prediction(AUC=0.743,95%CI:0.685–0.795,P<0.001).Conclusions:GDF-15,as a prognostic marker in patients with AHF,is not inferior to NT-proBNP.Combining the two markers could provide an early recognition of high-risk patients and improve the prediction values of AHF long-term prognosis.Clinical trial registration:ChiCTR-ONC-12001944,http://www.chictr.org.cn.

文摘Objective:Early identification of acute kidney injury(AKI)is essential to improve the prognosis of patients with acute heart failure(AHF).We aimed to determine the utility of neutrophil/lymphocyte ratio(NLR),N-terminal prohormone of brain natriuretic peptide(NT-proBNP),urea,and creatinine(Cr),as well as combinations of these,for the prediction of AKI in patients with AHF.Methods:A total of 153 patients with AHF under the care of Sun Yat-sen Memorial Hospital,Sun Yat-sen University from October 2009 to October 2019 were included in this retrospective observational study.Their NLR,NT-proBNP,urea,and Cr concentrations were measured on admission.AKI was defined using the Acute Kidney Injury Network criteria.Receiver operating characteristic(ROC)curves,the areas under the curves(AUCs),sensitivity,and specificity were employed to evaluate the ability of each biomarker and their combinations to identify AKI.This study was approved by the Ethics Committee of Sun Yat-sen Memorial Hospital,Sun Yat-sen University(approval No.SYSEC-KY-KS-2021-126)on June 22,2021.Results:Forty-six(30.1%)participants developed AKI during hospitalization.The NLR and NT-proBNP of the participants with AKI were higher than those without(NLR:median 7.886 vs 4.717,P<0.0001;NT-proBNP,median 6774 vs 2786pg/mL,P<0.0001).ROC analyses demonstrated that high NLR and NT-proBNP were associated with higher incidences of AKI(NLR:cut-off 5.681,AUC 0.716,sensitivity 58.9%,specificity 80.4%;NT-proBNP:cut-off 5320pg/mL,AUC 0.700,sensitivity 72.9%,specificity 65.2%).Moreover,a combination of NLR,NT-proBNP,urea,and Cr yielded an AUC of 0.815,sensitivity 80.4%,and specificity of 74.8%.In addition,the AUCs for the prediction of AKI in the participants with New York Heart Association(NYHA)classes II,III,and IV were 0.936,0.860,and 0.772,respectively,using this combination.Conclusion:A combination of NLR,NT-proBNP,urea,and Cr,measured at admission,may represent a promising tool for the prediction of AKI in patients with AHF.This method performs best for AKI risk assessment in patients with NYHA II,followed by those with NYHA III or IV.
文摘Background N-terminal-pro-brain natriuretic peptide(NT-pro-BNP)is associated with worse outcome in patients with acute myocardial infarction(AMI). However,the role of short-term follow-up of NT-pro-BNP level remains unclear. Methods Three hundred and sixty-two patients diagnosed with AMI were retrospectively enrolled in this study from March 2014 to March 2017 in our center. Blood samples were obtained at initial admission and again within 1 month after hospital discharge. The univariate and multivariate cox regression analyses including significant covariables were performed on NT-pro-BNP level at admission,discharge,or change from admission to discharge to predict adverse cardiovascular events(MACE)as study endpoints. Results There were 211 cases in NT-pro-BNP decrease group,while 151 cases in NT-pro-BNP increase group. The median follow-up was 365 days(interquartile range[IQR],322-861 days). After adjusting the covariables in the multiple logistic regression analysis,follow-up NT-pro-BNP level was still a significant independent predictor for MACE(OR,1.395;95% CI,1.102-1.869,P=0.005). However,the initial NT-pro-BNP level or change of NT-pro-BNP level had no significant predictive value for MACE. Conclusions A short-term follow-up NT-pro-BNP level after hospital discharge is a powerful prognostic biomarker for MACE in patients with AMI.

文摘BACKGROUND Clinical diagnosis of cirrhotic cardiomyopathy(CCM) often encounters challenges of lack of timeliness and disease severity, with the commonly positive indicator usually associated with advanced heart failure.AIM To explore suitable biomarkers for early CCM prediction.METHODS A total of 505 eligible patients were enrolled in this study and divided into four groups according to Child-Pugh classification: Group Ⅰ, Class A without CCM(105 cases);Group Ⅱ, Class A with CCM(175 cases);Group Ⅲ, Class B with CCM(139 cases);and Group Ⅳ, Class C with CCM(86 cases). Logistic regression and receiver operating characteristic(ROC) curve analyses were performed to determine whether red blood cell distribution width(RDW) was an independent risk factor for CCM risk. The relationships between RDW and Child-Pugh scores, Model for End-Stage Liver Disease(MELD) scores, and N-terminal pro-brain natriuretic peptide(NT-proBNP) were analyzed by Pearson correlation analysis.RESULTS A constant RDW increase was evident from Group Ⅰ to Group Ⅳ(12.54 ± 0.85, 13.29 ± 1.19, 14.30 ± 1.96, and 16.25 ± 2.13, respectively). Pearson correlation analysis showed that RDW was positively correlated with Child-Pugh scores(r = 0.642, P < 0.001), MELD scores(r = 0.592, P < 0.001), and NT-proBNP(r = 0.715, P < 0.001). Furthermore, between Group Ⅰ and Group Ⅱ, RDW was the only significant index(odds ratio: 2.175, 95% confidence interval [CI]: 1.549-3.054, P < 0.001), and it reached statistical significance when examined by ROC curve analysis(area under the curve: 0.686, 95%CI: 0.624-0.748, P < 0.001).CONCLUSION RDW can serve as an effective and accessible clinical indicator for the prediction of diastolic dysfunction in CCM, in which a numerical value of more than 13.05% may indicate an increasing CCM risk.
