ABSTRACT
Objective To observe the effects of recombinant human B-type natriuretic peptide (rhBNP) on cardiac function and heart rate variability (HRV) in patients with heart failure after acute myocardial infarction (AMI). Methods One hundred and twenty patients with heart failure after AMI admitted to the Department of Cardiology of Cangzhou Central Hospital of Hebei Province from January 2015 to January 2018 were enrolled. The patients were divided into a conventional treatment group and an rhBNP treatment group according to random number table method, with 60 cases in each group. The two groups were treated according to the AMI guidelines, the conventional treatment group received west medicine anti-myocardial ischemia and anti-heart failure treatment; the rhBNP treatment group received rhBNP on the basis of routine treatment; the first load dose was 2 μg/kg intravenous injection impact treatment, followed by maintaining dose 8.5 ng·kg-1·min-1 intravenous drip for 7 days. The changes of hypersensitivity C-reactive protein (hs-CRP), N-terminal B-type natriuretic peptide precursor (NT-proBNP), left ventricular ejection fraction (LVEF) and HRV index were observed before and after treatment in the two groups [HRV indexes including the changes of average normal RR interval standard deviation (SDNN), the average value of the normal RR interval standard deviation (SDANN), the root mean square (RMSSD) of the adjacent RR interval difference, and the percentage of adjacent RR interval difference > 50 ms (PNN50)]; the incidences of adverse reactions in the two groups were observed. Results After treatment, the levels of hs-CRP and NT-proBNP in the two groups were significantly lower than those before treatment (all P < 0.05). LVEF, SDNN, SDANN, RMSSD and PNN50 were higher than those before treatment, and the changes of the above indicators in the rhBNP treatment group were more significant than those in the conventional treatment group [hs-CRP (mg/L): 6.2±3.3 vs. 11.8±5.5, NT-proBNP (ng/L): 2.5±2.0 vs. 6.4±4.3, LVEF: 0.49±0.02 vs. 0.44±0.04, SDNN (ms): 93.3±18.1 vs. 79.1±16.0, SDANN (ms): 87.3±17.8 vs. 70.9±14.9, RMSSD: 30.3±11.0 vs. 23.8±10.4, PNN50: (15.9±7.3)% vs. (9.6±5.5)%, all P < 0.05]; No significant adverse reactions occurred during the treatment of the two groups. Conclusion rhBNP can significantly improve the heart function of patients with heart failure after AMI, reduce the levels of inflammatory response indicators and improve HRV;since its clinical efficacy is good, and its application safe, it is worthy to promote its clinical use.
ABSTRACT
Objective To study the early diagnostic value of high-sensitivity cardiac troponin Ⅰ(hs-cTnI) and soluble growth stimulating gene 2 protein (soluble suppression of tumorigenicity 2,sST2) in myocardial injury of acute organophosphorus pesticide poisoning (AOPP).Methods Totally 168 AOPP patients hospitalized from March 2014 to October 2018 were divided into the mild group (n=45),moderate group (n=55) and severe group (n=68).Another 30 healthy persons were served as the control group.The levels of cTnI,hs-cTnI,N-terminal B-type natriuretic peptide(NT-proBNP) and sST2 were detected at 4 h and 12 h after admission.SPSS 21.0 was used for statistical analysis.The measurement data were expressed by mean±standard deviation,two groups were compared by LSD-t test,and the multigroup comparison was made by single factor analysis of variance (ANOVA).The correlation analysis by Spearman correlation test (P<0.05).Results At 1 h after admission,the hs-cTnI of AOPP patients with different degrees of poisoning was higher than that of control group,and that of severe group was higher than that of mild to moderate group.Comparison between groups was statistically significant (P<0.05).However,there was no significant difference in the cTnI level (P>0.05).At 4 h and 12 h after admission,the levels of cTnI and hs-cTnI increased with the increase of poisoning degree and the extension of time,and their level at 12 h after admission were significantly higher than those at 4 h after admission,with statistically significant difference between the two groups (P<0.05).At 1 h after admission,the level of sST2 in the poisoned patients was higher than that in the control group,and the level in the severe group was higher than that in the mild to moderate groups.At 4 h and 12 h after admission,the level of sST2 was increased significantly,especially in the severe group.The level of sST2 at 12 h after admission was significantly higher than that at 4 h after admission (P<0.05).The concentration of NT-proBNP was in normal range 1 h after admission,increased gradually at 12 h after admission,and the level of NT-proBNP in the severe group was significantly higher than that in the other groups (P<0.05),and comparison between the groups was significantly different (P<0.05).The correlation analysis showed that there was a positive correlation between hs-TnI and sST2 in AOPP patients (r=0.776,P<0.01).hs-TnI and sST2 was positively correlated with the severity of AOPP (r=0.958,P<0.01;r=0.844,P<0.01).That is,the more severe the patient,the higher the concentration of hs-TnI and sST2,and the more serious myocardial injury.Conclusions Early detection ofhs-cTnI and sST2 levels in AOPP patients can identify early myocardial damage and objectively evaluate the extent of myocardial damage.
ABSTRACT
Objective@#To investigate the prognostic value of N-terminal B-type natriuretic peptide (NT-proBNP) on all-cause mortality in heart failure patients with preserved ejection fraction (HFpEF) at real world scenarios.@*Methods@#Patients who met the diagnostic criteria of HFpEF in the China National Heart Failure Registration Study (CN-HF) were divided into death and survival groups. The demographic data, physical examination, results of the first echocardiography, laboratory results at admission, complications, drug use and clinical outcomes were obtained from CN-HF. The univariate Cox proportional hazard model was used to screen the variates that might predict prognosis, and then the covariates with statistical significance were included in the multivariate Cox regression model to analyze the predictive value of baseline NT-proBNP on all-cause death. Spearman correlation analysis was used to evaluate the relationship between NT-proBNP and estimated glomerular filtration rate (eGFR), so as to further explore the predictive value of the interaction between renal dysfunction and NT-proBNP on death. Since NT-proBNP did not obey the binary normal distribution, it was expressed by the natural logarithm of NT-proBNP (LnNT-proBNP).@*Results@#A total of 1 846 HFpEF patients were enrolled in this study, with an average age of 71.5 years, 1 017 males(55.1%), median NT-proBNP 860 ng/L, and median eGFR 73.9 ml·min-1·1.73m-2. After a median follow-up of 34 months, 213 (11.5%) patients died. Patients in the death group were older, with higher NYHA classification Ⅲ-Ⅳ ratio, longer hospital stay, higher serum potassium and NT-proBNP level, prevalence of complications of diabetes mellitus, arrhythmia and atrial fibrillation, use of angiotensin receptor antagonist(ARB), mineralocorticoid receptor antagonists (MRA), diuretic and digoxin was significantly higher in death group than in survival group. Body mass index (BMI), diastolic blood pressure, left ventricular ejection fraction (LVEF), hemoglobin, serum cholesterol(TC), serum triglycerides (TG) and eGFR, and use of angiotensin converting enzyme inhibitors (ACEI), statins and aspirin were lower in death group than in survival group. Univariate Cox regression analysis showed that NT-proBNP was a predictor of all-cause death in HFpEF patients (HR=2.522, 95%CI 2.040-3.119, P<0.001). Multivariate Cox regression analysis showed that the elevated NT-proBNP remains as the independent predictor of all-cause death in patients with HFpEF (HR=1.230, 95%CI 1.049-1.442, P=0.011) after adjusting for age, BMI, diastolic blood pressure, LVEF, hemoglobin, serum potassium, serum sodium, TC, serum high-density lipoprotein cholesterol (HDL-C), TG, eGFR, atrial fibrillation, as well as the treatment of ACEI/ARB, MRA, diuretics and digoxin. Spearman correlation analysis showed that LnNT-proBNP was negatively correlated with eGFR (r=-0.361, P<0.001), but there was no interaction between NT-proBNP and renal dysfunction in predicting death in HFpEF patients (P>0.05).@*Conclusion@#The elevated level of NT-proBNP at admission is an independent predictor of all-cause mortality in HFpEF patients.

ABSTRACT
Objective To study the effect of preoperative blood pressure control on postoperative cardiovascular events in patients with hypertension and gastrointestinal surgery. Methods A total of 238 hypertensive patients who underwent gastrointestinal surgery were selected and divided into control group (n =118)and non-control group (n =120)according to thehypotensor treatment.During the operation,the same anesthetic regimen was used.The use of vasoactive drugs was recorded during anesthesia.Bladder chalone C (Cys C)and cardiac troponin T (cTnT)were de-tected in blood before and after the operation,and so were N-terminal B type natriuretic peptide (NT-proBNP)level on the 1st and 5th day after the operation.The postoperative hospitalization time,fol-low-up of cardiovascular events 28 and 90 days after discharge were recorded.Results Compared with the non-control group,the total dosage of ephedrine in the control group was significantly re-duced [(3.41±1.04)mg vs (7.46 ± 3.29)mg,P <0.05 ],total dose of phenylephrinewas signifi-cantly reduced [(0.17±0.10)mg vs (0.46 ±0.16)mg,P <0.05],postoperative hospital stay was significantly shorter [(5.92±1.15)d vs (9.65±1.61)d,P <0.05],NT-proBNP level in the control group on the 1st day after the operation [(108.00 ± 47.11 )pg/L vs (250.38 ± 62.92 )pg/L,P <0.01]and 5 days after the operation [(62.07 ±25.31)pg/L vs (199.02 ± 60.32)pg/L,P <0.01 ] was obviously reduced.There was no statistical difference in Cys C andcTnT between the two group-safter operation.The incidence of cardiovascular adverse events in the control group was significantly lower than that in the non-control group (28 d:13.6% vs 62.7%,90 d:23.3% vs 23.3%,P <0.05).Conclusion Strict control of preoperative blood pressure control in patients with hypertension can significantly reduce the incidence of cardiovascular events.
ABSTRACT
Objective To explore the diagnostic value of combined bedside detection of aminoterminal pro-B-type natriuretic peptide (NT-proBNP) and cardiac troponin I (cTnI) in the diagnosis of cardiac dyspnea. Methods A total of 120 patients with dyspnea admitted in our department from June 2014 to February 2016 were included in this study. At the time of admission, NT-proBNP and cTnI levels were measured by bedside test. Values of NT-proBNP>300 ng/L or cTnI>0.16 mg/L were defined as positive for cardiac dyspnea. According to the final diagnosis, patients were divided into two groups:cardiac dyspnea group (n=68) and pulmonary dyspnea group (n=52). At the same time, 30 healthy people were selected as control group. Values of NT-proBNP and cTnI were used for statistical analysis between the three groups. The sensitivity and specificity of NT-proBNP, cTnI and cTnI+NT-proBNP were compared between three groups. Results The levels of NT-proBNP and cTnI were significantly higher in pulmonary dyspnea group and cardiac dyspnea group than those in the control group, and the levels were significantly higher in cardiac dyspnea group than those of pulmonary dyspnea group (P<0.01). The detection sensitivity of NT-proBNP and cTnI alone was 67.65% and 52.94%, combined detection of both was up to 94.12%. The specificity of NT-proBNP and cTnI detection alone was 70.00% and 53.33%, respectively, and combined detection of both was up to 86.67%. The sensitivity of NT-proBNP+cTnI was significantly higher than that of NT-proBNP and cTnI alone (P<0.05), but there was no significant difference in the specificity between combined detection andindividual detection of NT-proBNP. The positive predictive value of the combined detection in the diagnosis of cardiac dyspnea was 94.12%(64/68), and the negative predictive value was 86.67%(26/30). Conclusion Bedside detection with combination of cTnI and NT-proBNP has important clinical application value in the rapid diagnosis of cardiac dyspnea, which is a rapid clinical testing method.

ABSTRACT
Objective: To study the relationship between plasma level of N-terminal B-type natriuretic peptide (NT-proBNP) and ventricular diastolic dysfunction in elder hypertensive patients without target organ damage. Methods: A total of 66 relevant patients treated in our hospital from 2012-03 to 2014-03 were studied. According to the standard of ventricular diastolic dysfunction, the patients were divided into 2 groups: Study group, n=27 patients with diastolic dysfunction and Control group, n=39 patients without diastolic dysfunction. The patients in Study group were further divided into 3 sub-groups based on Doppler classification of diastolic dysfunction:Grade 1, the patients with E/A90 ms, n=8. Grade 2, the patients with E/A>1.5, DT (150-220) ms, IVRT1.5, DT≤150 ms, IVRT NT-proBNP and ventricular diastolic dysfunction. Results: Plasma level of NT-proBNP was higher in Study group than that in Control group. NT-proBNP level in Grade 3-4 sub-group was obviously higher than those in Grade 1 and Grade 2 sub-groups, NT-proBNP level in Grade 2 sub-group was higher than that in Grade 1 sub-group. Pearson correlation analysis indicated that NT-proBNP level was positively related to systolic blood pressure, diastolic function and E/E’ (r=0.211, P=0.037, r=0.442, P=0.004 and r=0.556, P=0.000), while negatively related to E’/A’ (r=-0.372, P=0.000). Conclusion: The increased plasma level of NT-proBNP are highly support for ventricular diastolic dysfunction in elder hypertensive patients without target organ damage, NT-proBNP level is related to ventricular diastolic function.
