Abstract
Background Acute heart failure (AHF) is a clinical syndrome defined as the new onset or acutely decompensated heart failure (ADHF) leading to signs and symptoms of heart failure (HF). The critical cut-off values for these biomarkers that suggest high mortality are not clearly defined in previous studies. More studies are required to better understand the correlation of Pro- BNP and its association with HF. The primary objective is to study the role of Pro-BNP and critical factors in predicting outcomes in AHF patients presenting to a medical emergency. Materials and Methods The data from the patients presented with symptoms of HF in the Department of Medical Emergency at our hospital were recorded and analysed. AHF is a clinical syndrome defined as the new onset or ADHF leading to signs and symptoms of HF, as based on the European Society of Cardiology. Results The present study highlights the various risk factors of AHF in patients and their association with mortality. In the present study, mortality in patients with very high Pro-BNP levels ≥2000 pg/ml was significantly higher than in patients with moderately elevated Pro-BNP. The patients who survived after 5 days of hospitalization had Pro-BNP levels ≤2000 pg/ml, suggesting that very high Pro-BNP levels ≥2000 pg/ml are associated with fatal outcomes. Conclusion To conclude, diabetes and sepsis are critical factors for the hospitalization and mortality of patients with AHF in northern India. Very high Pro-BNP levels ≥2000 pg/ml in patients with AHF requiring hospitalization and associated with fatal outcomes.

Abstract
BACKGROUND Pro-b-type natriuretic peptide (Pro-BNP) is an inflammatory marker that indicates cardiac damage and inflammation. The elevation of this marker in COVID-19 patients can be used as a predictive factor in the prognosis of these patients. METHOD Our cross-sectional study investigated the evaluation of cardiac diagnostic test findings based on pro-BNP levels in pregnant COVID-19 patients in Sayyad Shirazi Hospital, Gorgan, Iran, in 2020-2022. A hundred and ten pregnant patients diagnosed with COVID-19 infection were evaluated for cardiac diagnostic tests (electrocardiogram (ECG) and echocardiography (Echo)) and pro-BNP levels. Data were analyzed using SPSS 25 software. Chi-square and Student's t-test will be used to test and compare the relationship between variables and compare them. A P-value less than 0.05 is considered statistically significant. The chi-square test was used to compare the ratio of qualitative variables among the groups if the presuppositions of chi-square distribution were established. Otherwise, Fisher's exact test was used. RESULT The mean age of participants were 31.06 ± 5.533 years and 49.1% of patients had pro-BNP levels above the cut-off value for predicting an adverse outcome of COVID-19. The mean ± standard deviation of pro-BNP levels in the low group was 46.125 ± 17.523 pg/mL and in the high group was 878.814 ± 1038.060 pg/mL. This study revealed that patients with higher pro-BNP plasma levels had a significant relation between, myocardial infarction (MI), pericardial effusion (PE), urgent Caesarean section (C/S), and mortality. In addition, no significant relation between gravid, trimester, vaccination, arrhythmia, heart block, and valves diseases with high pro-BNP levels was found. CONCLUSION The current research showed that pro-BNP levels can be used as a diagnostic and valuable prognostic tool in pregnant women to diagnose cardiac complications by using ECG and Echo.

Abstract
INTRODUCTION Immune checkpoint inhibitors (ICI) induced cardiac toxicity can present with non-specific symptoms and signs. Early recognition and treatment are important; however, diagnosis can be challenging. CASE REPORT We describe a 67-year-old woman with a history of ICI induced pneumonitis who presented with dyspnea, hypoxemia and pulmonary infiltrates while treated with pembrolizumab for lung cancer, initially diagnoses with relapssed pneumonitis. When her condition did not improve with steroids, NT-pro-BNP level was tested and was markedly high, prompting additional tests for heart failure. MANAGEMENT AND OUTCOME The patient was diagnosed with ICI induced left ventricular dysfunction and treated with steroids, beta blockers, diuretics, and ACE inhibitors. Her symptoms and imaging studies markedly improved. DISCUSSION Here, we review the literature on ICI induced cardiac toxicity and the role of NT-pro -BNP in triage of patients presenting with dyspnea in the emergency setting. We suggest that measurement of NT-pro -BNP be utilized in patients receiving ICI's and presenting with respiratory abnormalities, to rapidly assess for possible cardiac toxicity.

Abstract
Introduction We investigated association of pro-BNP, troponin-I, electrocardiography (ECG) and echocardiography (ECHO) during diagnosis and identification of cirrhotic cardiomyopathy in cirrhotic patients. Materials and methods Patients were divided into three groups as; compensated cirrhotic patients (group 1, n= 30), decompensated cirrhotic (group 2, n = 30) and control group (group 3, n = 30). ECHO, and ECG were performed, and troponin-I and levels of pro-BNP were analyzed. Results Average age of group 1 was 46.36 ± 16 years (range 19-86), 60% were female; group 2 was 57.03 ± 13.54 years (range 22-89), 56% female; and group 3 was 49.13 ± 0.95 years (range 18-80), 56% female. A significant increase in QTc was detected in compensated cirrhotic patients compared to the control group (p <0.05). Pro-BNP levels were significantly higher (p <0.05) in the compensated cirrhotic group compared to the control group. The levels of pro-BNP were also significantly higher in the decompensated cirrhotic group compared compensated cirrhosis group and control group (p <0.001). Conclusion The increase of pro-BNP levels with severity of the disease in cirrhotic patients and the prolongation of QTc interval supports an association between these factors with cardiomyopathy.

Abstract
BACKGROUND Plasma pro-BNP (brain natriuretic peptide) levels are often elevated in response to right ventricular (RV) volume and pressure overload, parameters potentially affected by exercise. Plasma pro-BNP levels change in association with long-term changes in pulmonary hemodynamics, thereby serving as a potential biomarker in pulmonary arterial hypertension (PAH). The 6-min Walk Test (6MWT) and pro-BNP level are often checked in a single office visit. There is no universal standard for measuring Pro-BNP levels relative to the timing of the 6MWT. Based on the studies in normal subjects indicating that pro-BNP levels changes after exercise, we hypothesized that the pro-BNP might rise after the 6MWT in PAH patients, potentially impacting clinical decisions. METHODS Patients at our center with WHO Group 1 PAH on active therapy at a stable dose for 30 days or more were enrolled. After resting the patient for 30 min, blood was drawn for baseline pro-BNP and a 6MWT was performed. Pro-BNP levels were drawn immediately after the 6MWT and 1 and 2 h later. Pro-BNP was measured using a commercially available ELISA kit. The levels before exercise and after exercise were compared using student's paired t tests. RESULTS There were 17 females and 3 male subjects. The mean age was 53 ± 11 years. Seven patients had systemic lupus erythematosus-related PAH, six had idiopathic PAH, three had scleroderma, three had portopulmonary hypertension, and one had HIV-related PAH. The mean PA pressure was 50 ± 15 mmHg with a mean pulmonary vascular resistance of 10 ± 4 Wood units. The majority of the patients were on multimodality PAH therapy, including parenteral prostacyclins. Mean 6MWT distance was 377 ± 140 m. In 14/20 patients, the pro-BNP level increased immediately after the 6MWT; in 12/20 patients, the pro-BNP level was elevated at 1 h post exercise. In the majority of the patients, the pro-BNP fell to baseline 2 h post 6MWT. CONCLUSION There appears to be a trend of pro-BNP level increasing immediately after exercise and continuing to be elevated at 1 h. Pro-BNP levels then return to baseline at 2 h post 6MWT.

Abstract
BACKGROUND Increased pro-brain natriuretic peptide (pro-BNP) or troponin T-hypersensitivity (TnT-HSST) levels are common in liver cirrhosis. We conducted a retrospective observational study aimed to evaluate the correlation of pro-BNP and TnT-HSST levels with the clinical characteristics, laboratory data and in-hospital outcomes of patients with liver cirrhosis. MATERIALS AND METHODS We selected cirrhotic patients admitted to our hospital between January 2011 and June 2014. All eligible patients had pro-BNP or TnT-HSST data, or both. The pro-BNP and TnT-HSST data were further divided according to the presence of cardiac diseases. RESULTS The prevalence of pro-BNP level >900pg/mL was 41.72% (63 of 151 patients). The prevalence of TnT-HSST level >0.05ng/mL was 11.22% (45 of 401 patients). In the overall analysis, pro-BNP level significantly correlated with red blood cell (RBC), platelet, ascites, blood urea nitrogen (BUN), creatinine (Cr), Child-Pugh score, model for end-stage liver disease (MELD) score and in-hospital death; TnT-HSST level significantly correlated with white blood cell, ascites, albumin (ALB), BUN, Cr, Child-Pugh score, MELD score and in-hospital death. In patients with cardiac diseases, pro-BNP level significantly correlated with RBC, ascites, BUN, Cr, Child-Pugh score and MELD score; TnT-HSST level significantly correlated with sex, ascites, white blood cell, ALB, BUN, Cr, Child-Pugh score, MELD score and in-hospital death. In patients without cardiac diseases, pro-BNP level significantly correlated with ascites, RBC, platelet, BUN, Cr, MELD score and in-hospital death; TnT-HSST level significantly correlated with age, ascites, RBC, ALB, BUN, Cr, Child-Pugh score, MELD score and in-hospital death. CONCLUSIONS Pro-BNP and TnT-HSST levels significantly correlated with the severity of liver dysfunction and in-hospital mortality in cirrhosis.

Abstract
OBJECTIVE To see the role of Vitamin D supplementation on physical status of patients suffering from Congestive Heart Failure (dilated cardiomyopathy). METHODS In this nonrandomized clinical trial, Forty three Patients with dilated cardiomyopathy who were not showing any significant improvements in physical performance on optimal treatment of heart failure were included. Vitamin D (200,000 IU) supplementation on weekly basis for a period of 12 weeks was added to heart failure treatment. And its effect was seen on 6 minutes' walk distance and Pro-BNP levels. SPSS version 19 was used for data analysis. Dependent sample t-test was used to see the significant effect of vitamin D supplementation on pre- intervention vitamin D levels, 6MWD and Pro-BNP. Taking p-value <0.05 as significant. RESULTS On clinical assessment most of the patients were in NYHA class II (65%), the percentages of NYHA Class I, III and IV was 19%, 9% and 7% respectively. The baseline mean vitamin D level of the study group was 16.59±3.54ng/ml and it raised to 31.97±3.64ng/ml after 12 weeks of supplementation with vitamin D, p value<0.0005. The mean distance travelled by the study group before the intervention was 806±380ft while it increased to 945±393ft after the intervention, p value of 0.008. The mean of pro-BNP level of the study group before the intervention was 1024±635 while it improved to 159±80 after the intervention with a significant p value<0.0005. CONCLUSION Vitamin D supplementation decreases the severity of HF as reflected by reduction in serum pro-BNP levels and significant increase in six minutes' walk distance.

Abstract
PURPOSE The analysis of biomarkers with a prognostic value in chronic heart failure (CHF) is in constant progress. This study aimed to evaluate the short-term prognostic value of angiopoietin-2 (Ang2), galectin-3 (Gal-3), myeloperoxidase (MPO), endostatin (End), and pro-brain natriuretic peptide (pro-BNP) as a conventionally accepted prognosis biomarker in CHF patients. METHODS AND RESULTS 146 consecutive patients with CHF due to left ventricular systolic dysfunction (LVEF<40% at echocardiography) were enrolled, and underwent serum/blood sample analysis after 12-h fasting. Within 1year, 25 (17%) patients died (D) or underwent heart transplantation (HT). D+HT patients showed higher values of Ang2 (Log Ang2: 8.97±0.52 vs. 8.45±0.69, p=0.0004), myeloperoxidase (MPO) (Log MPO: 5±1.1 vs. 4.2±1.3, p=0.005) and pro-BNP (Log pro-BNP: 8.70±0.9 vs. 7.45±1.3, p<0.00001). At univariate Cox regression, pro-BNP and Ang2 were the best predictors of 1-year mortality, with area under the curve (AUC)=0.78 for pro-BNP (68% sensitivity and 82% specificity to predict outcome for a cut-off value of 5109pg/mL, 95% confidence interval [CI] 0.70-0.85, p<0.0001) and AUC=0.73 for Ang2 (84% sensitivity and 61% specificity to predict outcome for a cut-off value of 5175pg/mL, 95% CI 0.65-0.80, p<0.0001). At multivariate analysis, pro-BNP was the only predictor of one-year D/HT. CONCLUSION In our series of CHF patients, Ang2 and pro-BNP showed the best predictive value for 1-year outcome, while only pro-BNP could independently predict D/HT.

Abstract
AIM: To assess residual diuresis and diverse variables according to body mass index (BMI).
METHODS: Cross-sectional study (n = 57), with 3 groups. Group A: BMI < 25, n = 22; Group B: BMI 25-30, n = 15; Group C: BMI > 30, n = 20. Diuresis, hematocrit, albumin, C-reactive protein, Malnutrition inflammatory score, Pro-BNP, Troponin T, leptin and insulin levels are expressed as median and ranges (r).
RESULTS: Albumin (g/dL): GA vs GC, 3.70 (r2.20-4.90) vs 3.85 (r3.40-4.90), P = 0.02. Diuresis (mL/d): GA 690 (r0-1780); GB 660 (r60-1800); GC 840 (r40-2840). Diuresis GA vs GC, P = 0.01. Leptin (ng/mL): GA vs GC, 3.81 (r0.78-69.60) vs GC, 32.80 (r0.78-124.50), P < 0.001. Insulin (µU/mL): GA vs GB, 7 (r2-44) vs 11.50 (r4-38), P = 0.02; GA vs GC, 7 (r2-44) vs 19.5 (r5-155), P = 0.0001. Troponin T and Pro-BNP levels were not different. Significant correlations: GC, Insulin-UF: ρ = 0.53; P = 0.03; TroponinT-diuresis: ρ = -0.48, P < 0.05; Pro-BNP-diuresis: ρ = -0.39, P < 0.01; Troponin T-ProBNP: ρ = 0.77, P < 0.0001; albumin-Troponin T: ρ = -0.66, P < 0.0001; albumin-ProBNP: ρ = -0.44, P < 0.05.
CONCLUSION: High BMI associated positively with higher diuresis and albuminemia, and negatively with TropT and Pro-BNP. High BMI-associated better survival may be explained by better urinary output, lowering cardiovascular stress.

Abstract
Background Certain adipokines exert direct effects on proteinuria, a cardiovascular risk factor ignored in hemodialysis. We measured different adipokines according to body mass index (BMI) in relation to proteinuria. Methods Patients numbered 57: group A (GA), BMI<25, n = 22; GB, BMI 25–30, n = 15; and GC, BMI > 30, n = 20. There were no statistical differences in age, sex, time on dialysis, cause of renal failure, diabetes, hypertension, C-reactive protein, or nutritional status. Measures were taken of 24-hour diuresis and proteinuria, ultrafltration, albumin, pro-brain natriuretic peptide (Pro-BNP), insulin, adiponectin, leptin, and ghrelin. Results Proteinuria was signifcantly higher in GC versus (vs) GA (1.5 g/day, range 0.30–14 vs 0.72 g/day, range 0.1–2.7; P < 0.01) and correlated signifcantly with leptin levels (ρ = 0.47, P < 0.05). In GA, elevated levels of Pro-BNP, adiponectin, and ghrelin were associated with lower degrees of proteinuria. Signifcant correlations were found between adiponectin and leptin (ρ = −0.54, P = 0.03), and adiponectin and Pro-BNP (ρ = 0.59, P = 0.02). Though not signifcant, there were more diabetics in GC (GA four, GB three, GC ten). As BMI increased in GB and GC, Pro-BNP, adiponectin, and ghrelin levels decreased signifcantly, while proteinuria, insulin, and homeostasis model assessment of insulin resistance increased. Leptin levels were signifcantly elevated in GC vs GA and GB. In GC, ghrelin correlated signifcantly with Pro-BNP (ρ = 0.51, P = 0.03), while leptin correlation with Pro-BNP was inverse and signifcant in GA (ρ = −0.74, P < 0.001) and inverse and nonsignifcant in GB and GC. Conclusion In patients with BMI < 25, higher adiponectin, ghrelin, and Pro-BNP levels were associated with lower proteinuria and leptinemia. In obesity, hyperleptinemia and hyperinsulinemia associated with higher proteinuria; whether decreased adiponectin–ghrelin–ProBNP and/or elevated leptin–insulin levels aggravate proteinuria remains to be determined.

Abstract
BACKGROUND To determine the prognostic value of pro B-type natriuretic peptide (pro-BNP) to predict mortality after transcatheter aortic valve implantation (TAVI). Logistic EuroSCORE (LES) overestimates observed mortality after TAVI. A new risk score specific to TAVI is needed to accurately assess mortality and outcome. METHODS Eighty-five patients were included. Indications for TAVI were nonoperable or surgically high-risk patients (LES>20%). Pro-BNP was measured 24h before the procedure. Cox proportional hazards model was used to evaluate clinical factors. The predictive accuracy of these Cox models was determined by using time-dependent receiver operating characteristic (ROC) curves. RESULTS Pro-BNP levels (log-transformed) were significantly higher in non-survivors than in survivors at 30 days (3.36 ± 0.43 vs. 3.81 ± 0.43, p<0.004) and at the end of follow-up (3.34 ± 0.42 vs. 3.63 ± 0.48, p<0.011). Multivariate analysis revealed that only increased log pro-BNP levels were associated with higher mortality rate at short [hazard ratio (HR) (95% confidence intervals (CI)]=5.35 (1.74-16.5), p=0.003] and long-term follow-ups [HR=11 (CI: 1.51-81.3), p=0.018]. LES was not associated with increased mortality at either time point [HR=1.03 (CI: 0.95-1.10), p=0.483 and HR=1.03 (CI: 0.98-1.07), p=0.230, respectively]. At 30, 90, 180, and 365 days, the c-index was 0.72 for log pro-BNP and 0.63 for LES (p=0.044). CONCLUSION Pre-procedure log transform of plasma pro-BNP levels are an independent and strong predictor of short- and long-term outcomes after TAVI and are more discriminatory than LES.

Abstract
INTRODUCTION Most studies reported using N-terminal pro-brain natriuretic peptide (NT-proBNP) in diagnosis of heart failure but there is controversy about use of these tests in determining prognosis and classification of severity of heart failure. The objective of this study was to determine the value of plasma NT-proBNP levels assessment in evaluation of mortality and morbidity of patients with systolic left ventricular dysfunction. METHODS A cohort study was performed in 150 patients with heart failure since September 2009 until February 2010. The patients were followed for 6 months to assess their prognosis. Patients were divided into two good and bad prognosis groups according to severity of heart failure in New York Heart Association (NYHA) class and frequency of hospital admission and mortality due to cardiac causes. Patients with good prognosis had ≥1 admission or no mortality or NYHA class ≥2 and patients that had one of this criteria considered as bad prognosis groups. Pro-BNP levels were measured at baseline and left ventricular ejection fraction (LVEF) was estimated with echocardiography. Data was analyzed with using Chi-square, t-test, ANOVA, Kruskal-Wallis tests. RESULTS In patients with heart failure that enrolled in this clinical study, ten patients were lost during follow-up. The mean of NT-proBNP is significantly correlated with ejection fraction (p=0.003) and NYHA class (p<0.001). In our study among 140 patients who were follow-up for 6 months, 11(9.7%) of individuals died with mean NT-proBNP of 8994.8±8375 pg/ml, in survived patients mean NT-proBNP was 3756.8±5645.6 pg/ml that was statistically significant (P=0.02). Mean NT-proBNP in the group with good prognosis was 2723.8±4845.2 pg/ml and in the group with bad prognosis was 5420.3±6681 pg/ml, difference was statistically significant (P=0.0001). CONCLUSION Our study in consistent with other studies confirms that NT-proBNP is significantly correlated with mortality and morbidity. This could be predicting adverse out come and stratification in patients with heart failure. It is recommended that more research be performed in Iran.
