ABSTRACT

Introduction: Identification of predictors for successful extubation in an Intensive Care Unity and use of Brain Natriuretic Peptides (BNP) in predicting mechanical ventilation weaning and extubation outcome. Aims: Evaluation of the effect of variables such as patient ́s age, severity score, use of sedation, use of vasoactive drugs, hydric balance, blood gas data, days under mechanical ventilation, the occurrence of adverse events and plasma BNP levels on the success of extubation.Method: A prospective cohort study of adult patients admitted to a 12- bed-general ICU, from April 1st 2016 to August 10th 2017, under mechanical ventilation for > 24 h, accompanied until discharge or death. Clinical variables were analyzed and BNP was assessed before initiation of Spontaneous Breathing Trial (SBT) and then again before extubation. Statistical Analysis: a descriptive and comparative data analysis, univariate and logistic regression analysis for verification of variables independently related to successful extubation (p < 0.05).Results: Study of 105 patients, mean age of 53.9 ± 19.8 years, 81% of success in extubation; the overall mortal-ity rate of 11.4%; variables associated to successful extubation: age, APACHE II, SAPS II, days of hospitalization before ICU admittance, days under mechanical ventilation, days of stay in ICU and occurrence of nosocomial infec-tion (p < 0.05); BNP levels were lower in patients with successful extubation although not statistically significant; multivariate analysis showed that patient's age and days of hospitalization before ICU admittance were each in-dependently linked to extubation failure; APACHE II score and days of hospitalization before ICU admittance were each independently associated to risk of death.Conclusion: Despite being older and with higher severity scores, patients had a higher success rate in extubation than found in similar studies. However, the mortality rate in cases of failed extubation was higher. Data obtained was in agreement to studies that suggested that patient ́s age, severity score, days of hospitalization before ICU admittance, days of stay in ICU, days under MV and infection occurrence were all variables associated as much extubation failure as to risk of death. A direct association between BNP levels and successful extubation and the usefulness of assessing BNP in the conduction of WMV was not confirmed. (AU)


Introdução: Identificação de fatores preditivos do sucesso da extubação em Unidade de Terapia Intensiva e uso do Peptídeo Natriurético Cerebral (BNP) como preditor do sucesso do desmame da ventilação mecânica e extubação.Objetivo: Avaliação do efeito de variáveis como idade, escores de gravidade, uso de sedação, uso de drogas va-soativas, balanço hídrico, gasometria, dias sob ventilação mecânica, ocorrência de eventos adversos e níveis plas-máticos de BNP no sucesso da extubação .Método: Estudo de coorte prospectivo de pacientes adultos internados em UTI geral com 12 leitos, de 1º de abril de 2016 a 10 de agosto de 2017, sob ventilação mecânica (VM) por > 24 horas, acompanhados até a alta ou óbito. Variáveis clínicas foram analisadas e o BNP dosado antes do início do Teste de Respiração Espontânea (TRE) e, novamente, antes da extubação. Análise estatística: análise descritiva e comparativa dos dados, análise univariada e regressão logística para verificação de variáveis independentemente relacionadas ao sucesso da extubação (p <0,05).Resultados: Avaliados 105 pacientes, idade média 53,9 ± 19,8 anos, sucesso na extubação de 81%; taxa de mortalidade geral de 11,4%; variáveis associadas ao sucesso da extubação: idade, APACHE II, SAPS II, dias de internação antes da admissão na UTI, dias em ventilação mecânica, dias de permanência na UTI e ocorrência de infecção hospitalar (p <0,05); os níveis de BNP foram mais baixos em pacientes com sucesso da extubação, embora não estatisticamente significativos; a análise multivariada mostrou que as variáveis, idade e dias de internação, antes da admissão na UTI, estavam, independentemente, ligadas ao fracasso da extubação; as variáveis APACHE II e dias de internação antes da admissão na UTI estavam, independentemente, associados ao risco de morte.Conclusão: Apesar de mais velhos e com escores de gravidade mais elevados, nossos pacientes apresentaram maior taxa de sucesso na extubação quando comparados a estudos semelhantes. No entanto, a taxa de mortalidade em casos de falha da extubação foi maior. Os dados obtidos estão de acordo com estudos que sugerem que variá-veis como idade, escores de gravidade, dias de internação antes da admissão na UTI, dias de permanência na UTI, dias em VM e ocorrência de infecção estão associadas tanto ao fracasso de extubação quanto ao risco de morte. Não foi possível confirmar a associação direta entre os níveis plasmáticos de BNP e o sucesso da extubação, assim como sua utilidade na condução do desmame da ventilação mecânica. (AU)

ABSTRACT

Abstract Introduction: Atrial fibrillation (AF) is the most common sustained arrhythmia. Sorting nexin 10 (SNX10) has been reported to be an important regulator in embryonic development and human diseases, however, little is known about its role in cardiac disease. The aim of this study was to investigate the clinical significance of SNX10 expression in AF. Methods: Nineteen valvular heart disease patients with AF and nine valvular heart disease patients with sinus rhythm (SR) were enrolled. Atrial tissue samples from patients undergoing open heart surgery were examined. Atrial tissues of normal hearts were obtained from two cases' autopsies. The SNX10 expression and its associations with the degree of fibrosis were analyzed by immunohistochemistry and Masson's trichrome staining. Results: SNX10 expression was detected in the cytoplasm of cardiac cells in human myocardial tissue. The SNX10 expression level was higher in the SR group than in the AF group (P=0.023). SNX10 expression was negatively associated with the degree of fibrosis (P=0.017, Spearman rho=-0.447), the New York Heart Association degree (P=0.003, Spearman rho=-0.545), left atrial diameter (P=0.038, Spearman rho=-0.393), right atrial diameter (P=0.043, Spearman rho=-0.386), and the brain natriuretic peptide (BNP) level 24 hours after surgery (P=0.030, Spearman rho=-0.426), but not the BNP level before surgery and 72 hours after surgery. No statistical significance was observed between SNX10 and the level of troponin T and C-reactive protein. Conclusion: Decreased SNX10 might serve as a potential risk factor in AF of the valvular heart disease.

ABSTRACT

@#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.

ABSTRACT

Heart failure is a clinical condition in which a deviation in normal cardiac structure or function is accountable for the incapability of the heart to eject or fill with blood at a proportion proportionate to the requirements of the metabolizing tissues. The detection of heart failure is based on clinical symptoms, signs, chest x rays and reaction to the treatment. BNPs are released by the heart ventricles in reaction to volume load or pressure load physiologically and they function to counteract rennin angiotensin system, cause vasodilatation and natriuresis. The BNP evaluation has gained approval already in the recommendations of European Society of Cardiology for the detection of heart failure. We wanted to study the potential of a new unconventional assay plasma N-Terminal pro BNP in detecting cardiac failure, and correlate the levels of plasma N-Terminal pro BNP with the severity of the cardiac failure and levels of plasma N-Terminal Pro BNP with systolic and diastolic dysfunction. MethodsIt was an analytical cross-sectional study conducted among 50 patients with clinical features of cardiac failure attending medicine OPD and emergency department of the hospital for the duration of 18 months and an equal number of age and sex equivalent fit controls. In subjects with clinical features of heart failure, and in healthy controls, 2 mL of blood sample is drawn for assay of plasma N-Terminal pro BNP within half an hour of presentation. Using biomedical kit plasma N-T pro BNP concentration was measured. The entire period of the assay is 18 min. Detectability range by this method of N-T proBNP is 5 pg/mL to 35,000 pg/mL. ResultsCases comprised of 28 males and 22 females with a mean age 50.80 (13.11) years while controls comprised of 28 males and 22 females with a mean age 50.86 (12.7) years. There was a statistically noteworthy difference in Mean N-T pro BNP between case and control groups, NYHA Class, and age group. Mean N-T pro-BNP is not significantly different at discharge and on 2nd follow-up. For the rest of the diagnoses, there is a notable difference in Mean N-T pro BNP at discharge and on 2nd follow-up. ConclusionsPlasma N-Terminal pro BNP levels are useful from therapeutic point of view (aggressive therapy if needed e.g. Heart transplantation / bilateral pacemaker or invasive therapy may be planned by N-T pro BNP levels).

ABSTRACT

Background: The incidence and prevalence rates of heart failure (HF) are increasing worldwide. The prevalence of HF rises exponentially with increasing age and affects 4% to 8% of people older than 65. The leading causes of HF in India include coronary artery disease (CAD), diabetes, hypertension, rheumatic valvular heart diseases and primary cardiac muscle diseases. Rheumatic heart disease (RHD) is still a common cause of HF in India. Epidemiological studies have estimated that 1.5% to 2% population experience HF and it is the main reason for hospital admission of elderly patients. The objective of this study was to establish the etiological factors of heart failureMethods: A cross sectional study of 150 patients above the age of 18 years presented with heart failure diagnosed clinically on the basis of Framingham heart failure criteria and echocardiography, done over a period of one year in department of medicine in BRD medical college Gorakhpur Uttar Pradesh.Results: A total of 150 patients were include in this analysis the majority of patients were male (57.3%). Age of patients ranged from 18 - 70 years and 84% patients were above the age of 40 years.Conclusions: Heart failure was more prevalent in elderly male above 40 years of age. Myocardial infarction, DCMP, rheumatic heart disease and hypertensive heart failure are the common etiology leading to heart failure.

ABSTRACT

ObjectiveThe assessment of volume load status in patients with acute heart failure is of great significance for preventing volume overload. The aim of this study was to explore the predictive value of NT-proBNP level and IVC-CI on volume load and prognosis in patients with acute heart failure. MethodsFrom January 2017 to April 2019, the clinical characteristics of 98 patients with acute heart failure diagnosed and treated in the Peking University People's Hospital were retrospectively reviewed in this study. All of them were treated with routine anti-heart failure treatment. According to the level of relative volume balance, they were divided into volume overload group (65 cases) and non-volume overload group (33 cases). All the patients were followed up for 30 days after discharge. The patients with death and cardiogenic rehospitalization were included in the event group (30 cases), and the rest were in the non-event group (68 cases). NT-proBNP and IVC-CI in different volume load groups and different prognosis groups were compared. The volume index levels (serum albumin, hemoglobin, hematocrit, PCWP, CVP) of patients in different volume load groups were compared. The effects of NT-proBNP and IVC-CI on volume load and prognosis of patients were analyzed.ResultsThe levels of NT-proBNP [(1306.39±313.98)pg/mL], PCWP [(19.63±1.95)mmHg] and CVP [(14.65±1.03)cmHg] in the volume overload group were higher than those in the non-volume overload group, while the IVC-CI [(38.26±8.14)%], albumin [(16.23±2.12)g/L], hemoglobin and hematocrit [(36.26±2.78)%] in the volume overload group were lower than those in the non-volume overload group (P0.05). On discharge, the AUC of NT-proBNP, IVC-CI in predicting patients with acute heart failure was respectively 0.806 and 0.847. Although the prediction accuracy was relatively high, the AUC of combined prediction was 0.982, which was significantly higher than that of NT-proBNP and IVC-CI (Z=3.589, 3.274, both P<0.05).Conclusion There is a correlation between NT-proBNP, IVC-CI and volume indexes. The combined detection of NT-proBNP and IVC-CI can help to assess the volume load status of patients with acute heart failure and improve the predictive value of short-term prognosis of patients.

ABSTRACT

Objective: To use Escherichia coli ( E. coli) to prepare the recombinant proteins of elastin-like polypeptide (ELP) for displaying the two epitopes of N-terminal pro-brain natriuretic peptide (NT-proBNP)» and to provide the basis for the low-cost and high-efficiency preparation of NT-proBNP detection calibrator. Methods: The epitopes of 13 20 and 63 71 amino acid residues of NT-proBNP were designed and fused with ELP by flexible chain; three kinds of fusion proteins were obtained. The genes encoding the three fusion proteins mentioned above were synthesized by genetic engineering technique and cloned into the pET-28a ( +) vector; the recombinant proteins were induced and expressed automatically in F. coli BL21 (DE3), the recombinant proteins were purified with inverse transition cycling (ITC), and the abilities of their antibodies specificly binding epitopes were detected by Western blotting and ELISA methods. Results: Three kinds of vectors of ELP for displaying NT-proBNP epitopes were successfully constructed, and the corresponding recombinant proteins were expressed in the E. coli. The western blotting and direct ELISA results showed that the specific epitopes displayed by ELP had the better binding ability with the relative antibodies. The results of Sandwich ELISA showed that the protein concentrations of recombinant proteins of ELP for displaying two epitopes of NT-proBNP had a double logarithmic linear dose-dependent relationship with the absorbance (A) value at 450 nm ( r=0.919 1-P<0.01). Conclusion: The ELF is successfully used to display the two epitopes of NT-proBNP. and lay a foundation for the low-cost and high-efficiency preparation of the NT-proBNP detection calibrator.

ABSTRACT

OBJECTIVE:To observe the clinical effect and safety of recombinant human brain natriuretic peptide (rhBNP) combined with levosimendan in the treatment of acute decompensated heart failure (ADHF)complicated with renal insufficiency. METHODS:A total of 156 patients with ADHF complicated with renal insufficiency admitted to the Dept. of Cardiology in the Affiliated Hospital of Southwest Medical University during Jan.-Dec. 2019 were randomly divided into rhBNP group ,levosimendan group and combination group ,with 52 patients in each group. All patients received rountine treatment. On this basis ,rhBNP group was given rhBNP for injection [after 1.5 μg/kg intravenous pulse injection,intravenous dripping for 24 h with 0.007 5 μg(/ kg· min)];leosimendan group was given Leosimendan injection 12.5 mg [intravenous dripping for 1 h with 6-12 μg(/ kg·min),then intravenous dripping for 23 h with 0.1 μg(/ kg·min)]. Combination group received drug combination according to the administration method of single drug group. Three groups received treatment for consecutive 7 d. Cardiac function indexes [heart rate (HR),left ventricular ejection fraction (LVEF),left ventricular end-diastolic diameter (LVEDD)],mean arterial pressure (MAP),pulmonary capillary pressure (PCWP),renal function indexes [estimated glomerular filtration rate (eGFR),serum creatinine (Scr)],serum levels of cystatin C (Cys-c)and amino-terminal brain natriuretic peptide precursor (NT-proBNP)were observed in 3 groups before and after treatment. Clinical efficacy and the occurrence of ADR were recorded. RESULTS :Three cases withdrew from the study in rhBNP group and 1 case in levosimendan group ;152 cases completed the study. Before treatment ,there was no statistical significance in cardiac function indexes ,MAP,PCMP,renal function indexes or serum levels of Cys-C and NT-proBNP among 3 groups(P>0.05). After treatment ,the HP ,MAP,PCWP and serum level of NT-proBNP in 3 group as well as serum level of Cys-C in combination group were decreased significantly (P<0.05);the LVEF in 3 group as well as the eGFR and Scr level in levosimendan group and combination group were significantly increased (P<0.05),compared with before treatment ;above indexes of combination group were significantly better than those of rhBNP group and levosimendan group (P<0.05). Total effective rate of combination group was 94.23% ,which was significantly higher than those of rhBNP group (77.55%)and levosimendan group (76.47%)(P<0.05). There was no significant difference in the incidence of ADR among 3 groups(P> 0.05). CONCLUSIONS :rhBNP combined with levosimendan in the treatment of ADHF complicated with renal insufficiency can significantly increase the clinical efficacy ,and improve cardiac and renal function but don ’t increase the incidence of ADR.

ABSTRACT

@#Objective    To explore the predictive value of N-terminal-pro-brain natriuretic peptide (NT-ProBNP) for postoperative early outcomes in infants with aortic coarctation (CoA). Methods    A retrospective study was conducted in 344 children with CoA admitted to our hospital from September 2014 to October 2017, including 206 males (59.9%) and 138 females (40.1%), with an average age of 0.2-60.0 (7.1±10.6) months. The levels of NT-proBNP, clinical characteristics, imaging data and early follow-up results were collected and analyzed. Results    Compared with the normal NT-proBNP group, there were statistical differences in age, the proportion of RACHS-1≥3, the proportion of preoperative pneumonia and dysplastic aortic arch, preoperative cardiac function, left ventricular wall thickness, left ventricular dilatation, hospital stay, ICU duration, ventilator duration, duration of vasoactive drugs use, delayed chest closure, nasal continuous positive airway pressure (nCPAP), postoperative cardiac insufficiency in the abnormal NT-proBNP group (P<0.05). According to multivariate logistic regression analysis, NT-proBNP level (>3 000 pg/mL) was an independent risk factor for prolonged ICU duration [OR=3.17, 95%CI (1.61, 6.23)], prolonged ventilator duration [OR=5.84, 95%CI (2.86, 11.95)], prolonged use of vasoactive drugs [OR=2.22, 95%CI (1.22, 4.02)], postoperative cardiac insufficiency [OR=3.10, 95%CI (1.64, 5.85)]; NT-proBNP level (> 5 000 pg/mL) was an independent risk factor for delayed chest closure [OR=3.55, 95%CI (1.48, 8.50)]. Conclusion    NT-proBNP level in children with CoA can be affected by  many factors, including age, complexity of congenital heart disease, preoperative cardiac insufficiency, et al. The level of NT-proBNP has predictive value for postoperative early outcomes.

ABSTRACT

Resumen Introducción: La utilidad clínica del péptido natriurético cerebral (NT-proBNP) como marcador pronóstico en pacientes pediátricos con falla cardíaca es controversial. El puntaje inotrópico vasoactivo 24 horas después de la operación cardíaca en pacientes pediátricos es un importante predictor de morbilidad y mortalidad posoperatoria. Objetivo: Determinar si existe correlación entre los valores séricos de NT-proBNP y el puntaje inotrópico vasoactivo a las 24 horas posteriores a la intervención cardíaca en pacientes pediátricos atendidos en una unidad de terapia intensiva. Material y métodos: Estudio transversal analítico. Se realizó un análisis de correlación de Spearman (rs) entre la cifra sérica de NT-proBNP y el puntaje inotrópico máximo tomados ambos a las 24 horas del postoperatorio. Se consideró estadísticamente significativo un valor de p menor que 0.05. Resultados: Se incluyó a 40 pacientes, 52.5% del sexo masculino, 72.5% era mayor de un año de edad al momento de la operación. Se encontró una baja correlación (rs = 0.26) entre las concentraciones séricos de NT-proBNP y el puntaje inotrópico vasoactivo máximo a las 24 horas; dicha correlación no fue estadísticamente significativa (p = 0.09). Conclusiones: Este estudio es el primero en investigar la correlación entre estos marcadores y los resultados podrían sentar un antecedente que marque el inicio de múltiples investigaciones, con la finalidad de establecer nuevas herramientas diagnósticas, pronósticas y terapéuticas.


Abstract Introduction: The clinical utility of brain natriuretic peptide (NT-proBNP) as a prognostic marker in pediatric patients with heart failure is controversial. The maximum vasoactive inotropic score at 24 h after cardiac surgery in pediatric patients is an important predictor of morbidity and postoperative mortality. Objective: To determine if there is a correlation between the serum levels of NT-proBNP and the maximum vasoactive inotropic score at 24 hours after cardiac surgery in pediatric patients seen in the Intensive Care Unit. Material and methods: An analytical cross-sectional study. A Spearman correlation analysis (rs) was performed between the serum level of NT-proBNP and the maximum inotropic score both taken at 24 hours postoperatively. A value of p less 0.05 was considered statistically significant. Results: 40 patients were included, 52.5% to the male sex, 72.5% were older than 1 year of age at the time of surgery. A low correlation (rs = 0.26) was found between the serum levels of NT-proBNP and the maximum vasoactive inotropic score at 24 hours, this correlation was not statistically significant (p = 0.09). Conclusions: To our understanding, the present study is the first to investigate whether there is a correlation between these markers, so our results could set an important precedent that marks the beginning of multiple investigations in our critically ill patients in order to establish new diagnostic, prognostic and therapeutic approaches.

ABSTRACT

Introduction: Acute dyspnea is one of the most common reasons for admission to emergency rooms. It could be due to potentially life-threatening cardiac or respiratory conditions. Differentiation among these three disorders is frequently needed. In the condition of heart failure, where there is clinical need for early and appropriate treatment but no objective method for rapid diagnosis, the potential benefits are enormous for any biomarker that can reliably rule in or rule out this syndrome. Objectives: The objectives of this study are as follows: (i) To evaluate the role of point of care of brain natriuretic peptide (BNP) in acute dyspnea and (ii) To determine the cutoff level of BNP to differentiate between cardiogenic and noncardiogenic causes of dyspnea. Materials and Methods: This was an in-hospital cross-sectional study conducted at a tertiary care center. Patients were evaluated using predetermined performa. All these patients were subjected to routine blood investigations, digital chest X-ray, and 12-lead electrocardiography. At the same time point of care, BNP was done in each patient after obtaining informed written consent. All patients with BNP >100 or clinical suspicion for heart failure underwent two-dimensional echocardiography (ECHO) with color Doppler. Results: A cross-sectional study was conducted on 238 patients presenting with acute dyspnea. Almost all patients with BNP level >415 pg/ml had <45% ejection fraction, but patients with BNP level <415 pg/ml had echocardiographic findings not suggestive of heart failure. Conclusion: This study gives us a reliable cutoff level of 415 pg/ml of BNP which clearly distinguishes between cardiogenic versus noncardiogenic dyspnea.

ABSTRACT

Transfusion-associated circulatory overload (TACO) is recently becoming more important than transfusion-related acute lung injury (TRALI) in terms of the number of patients with definite diagnosis as well as its prognosis. In order to diagnose TACO, it is helpful to recognize early the symptoms suspicious of transfusion reaction through electronic medical record system and computer network, and this will be of help for obtaining samples for brain natriuretic peptide (BNP) measurement before and after the onset of transfusion reaction. We report a case in which a transfusion reaction was diagnosed as TACO. A 62-year-old woman was admitted to the emergency room due to bleeding tendency. Two fresh frozen plasma units and one unit of leukocyte-reduced red blood cells were transfused. Blood pressure increased during transfusion, and the chest X-ray showed findings suggestive of newly developed pulmonary edema. N-terminal prohormone of BNP (NT-proBNP) test was carried out using the specimens in refrigerated storage. Compared with the NT-proBNP level measured 12 hours before the transfusion, that measured 6 hours after the transfusion was markedly increased (>48 fold of pre-transfusion level). As a result, this case was diagnosed with TACO.

ABSTRACT

Objective To investigate the clinical effects of levosimmentan combined with freeze-dried recombinant human brain natriuretic peptide in elderly patients with heart failure. Methods Eighty patients with heart failure diagnosed in our hospital from January 2015 to January 2018 were selected as subjects. According to the random number table prepared in Excel 2007,40 patients in the experimental group and the control group were given. For basic treatments such as diuresis,the experimental group was treated with levosimtan combined with lyophilized recombinant human brain natriuretic peptide,and the control group was treated with levosimtan and dobutamine. The left ventricle of the two groups before and after treatment was compared. End-diastolic period (LVEDD),left ventricular ejection fraction(LVEF),cardiac index(CI),stroke volume(SV),serum cystatin C (Cys-C),amino terminal brain natriuretic peptide precursor(NT-proBNP),mean arterial pressure(MAP), pulmonary capillary pressure(PCWP). Results Before treatment,the differences of LVEDD,LVEF,CI and SV levels between the experimental group and the control group were not statistically significant(P > 0.05). After treatment,the LVEDD of the experimental group was significantly lower than that of the control group(P < 0.05).The LVEF,CI and SV values in the experimental group were significantly higher than those in the control group (P < 0.05). There was no significant difference in serum Cys-C and NT-proBNP levels between the experimental group and the control group before treatment(P > 0.05). After treatment,the serum levels of Cys-C and NT-proB-NP in the experimental group were significantly lower than those in the control group(P < 0.05). Before treatment,the difference of MAP and PCWP levels between the experimental group and the control group was not statistically significant(P > 0.05). After treatment,the MAP and PCWP levels in the experimental group were significantly lower than those in the control group(P < 0.05). The incidence of adverse reactions in the experimental group was 10.00% and the difference between the control group and the control group was not statistically significant(P > 0.05). Conclusions Levosimmentan combined with freeze-dried recombinant human brain natriuretic peptide in patients with senile heart failure can significantly improve cardiac function,reduce Cys-C,NT-proBNP levels,and improve hemodynamic parameters.

ABSTRACT

0bjective To investigate the occurrence of frequent intradialytic hypotension in hemodialysis patients and Analyzed influencing factors. Methods The 1 933 hemodialysis sections of 156 maintenance hemodialysis patients in the Huashan hospital affiliated to Fudan University in Shanghai were selected, and divided into frequent intradialytic hypotension and non- frequent intradialytic hypotension depending on whether the incidence of intradialytic hypotension is greater than 20%, and the patients' dialysis data and biochemical examination data are collected for the analysis of influencing factors. Results The incidence of frequent IDH in maintenance hemodialysis patients was 62.18%(97/156), and the pre-dialysis blood pressure of frequent IDH patients were higher than non-frequent IDH patients, frequent IDH patients: (134.02±21.01)/(73.85±10.73) mmHg(1 mmHg=0.133 kPa), non-frequent IDH patients: (124.66 ± 17.89)/(69.32 ± 10.65) mmHg, (t=-2.851,-2.558, P<0.05), but lower in post-dialysis, frequent IDH patients:(114.91±19.21)/(68.38±11.41) mmHg, non-frequent IDH patients: (127.90± 20.58)/(74.46±11.79) mmHg, (t=3.989, 3.189, P<0.01). Binary Logistic regression analysis showed that hemoglobin ( OR=0.354, P=0.015) and high-density lipoprotein ( OR=0.155, P=0.003) were protective factors for the occurrence of frequent IDH, and ultrafiltration volume/weight ( OR=6.021, P=0.002) and N-terminal pro-brain natriuretic peptide ( OR=2.687, P=0.020) were risk factors. Conclusions The incidence of frequent IDH in hemodialysis patients is high, and patients with high filtration rate, high N-terminal pro-brain natriuretic peptide, low hemoglobin and high density lipoprotein should be paid close attention to. It is recommended to regularly monitor patients' biochemical indicators, strengthen blood pressure monitoring for high-risk groups, and timely deal with the symptoms of low blood pressure.
