Electrophysiological changes of autonomic cells in left ventricular outflow tract in guinea pigs with iron deficiency anemia complicated with chronic heart failure

Objective: To investigate the electrophysiological changes of autonomic cells in left ventricular outflow tract in guinea pigs with iron deficiency anemia complicated with chronic heart failure.Methods: Guinea pigs model of iron deficiency anemia complicated with chronic heart failure in 10 guinea pigs of the experimental group was made by feeding a low iron diet,pure water and subcutaneous injection of isoproterenol. The control group consisting of 11 guinea pigs was given normal food, normal water and injected with normal saline. The left ventricular outflow tract model specimen was also prepared. The standard microelectrode technique was used to observe electrophysiological changes of autonomic cells in the outflow tract of left ventricular heart failure complicated with iron deficiency anemia in guinea pig model. The indicators of observation were maximal diastolic potential, action potential amplitude, 0 phase maximal depolarization velocity, 4 phase automatic depolarization velocity, repolarization 50% and 90%, and spontaneous discharge frequency.Results: Compared with the control group, 4 phase automatic depolarization velocity,spontaneous discharge frequency and 0 phase maximal depolarization velocity decreased significantly(P < 0.01) and action potential amplitude reduced(P < 0.01) in model group. Moreover, repolarization 50% and 90% increased(P < 0.01).Conclusions: There are electrophysiological abnormalities of the left ventricular outflow tract in guinea pigs with iron deficiency anemia complicated with heart failure.

Prognostic impact of atrial fibrillation on clinical outcomes of acute coronary syndromes,heart failure and chronic kidney disease

Atrial fibrillation(AF) is the most common type of sustained arrhythmia,which is now on course to reach epidemic proportions in the elderly population. AF is a commonly encountered comorbidity in patients with cardiac and major non-cardiac diseases. Morbidity and mortality associated with AF makes it a major healthcare burden. The objective of our article is to determine the prognostic impact of AF on acute coronary syndromes,heart failure and chronic kidney disease. Multiple studies have been conducted to determine if AF has an independent role in the overall mortality of such patients. Our review suggests that AF has an independent adverse prognostic impact on the clinical outcomes of acute coronary syndromes,heart failure and chronic kidney disease.

Development of Nursing Protocol for Preventing Interruptions during Clinical Examinations and Treatments in the Early Days of Hospitalization for Acute Exacerbation of Chronic Heart Failure in Patients with Impaired Cognitive Function

The purpose of this study is to prepare a nursing protocol for preventing interruptions during clinical examinations and treatments performed in the early days of hospitalization for acute exacerbation of chronic heart failure in patients with impaired cognitive function. For the first stage of the research, we prepared a draft of the nursing protocol based on a basic survey. For the second stage, semi-structured interviews were conducted with 5 nurses specialized in chronic heart failure and 11 nurses in dementia care to ensure content validity of the draft protocol. For the third stage, we examined the possibility of clinical application of the revised version of the protocol draft prepared in the second stage of the study. For assessment items, significant points of nursing care, and specific nursing care practice in this revised version, 73 subjects (84.9%) considered effective for patients, in terms of prevention of interruptions during clinical examinations and treatments in the early days of hospitalization. All items and contents were considered useful by more than 60% of the nurses. Considering that the nurses working in the clinical setting reported 84.9% of usefulness, we concluded that this nursing protocol remained valid at a certain level. We consider that this nursing protocol will be useful especially for newly graduated/employed nurses as a procedure manual which can reduce their anxiety or stress caused by lack of knowledge or experiences.

Development of Nursing Protocol for Preventing Discontinuation of Treatments by Methods Other than Physical Restraint during Acute Exacerbation of Chronic Heart Failure in Patients with Impaired Cognitive Function

The purpose of this study is to prepare a nursing protocol for preventing discontinuation of treatments using a method other than physical restraint during acute exacerbation of chronic heart failure in patients with impaired cognitive function. For the first stage of the study, we prepared a draft of the nursing protocol based on a basic survey. For the second stage, semi-structured interviews were conducted with 5 nurses specialized in chronic heart failure and 10 nurses in dementia case to ensure content validity of the draft protocol. For the third stage, we examined the possibility of clinical application of the revised version of the protocol draft prepared in the second stage of the study. For assessment items, significant points of nursing care, and specific nursing care practice in this revised version, 154 subjects (93.9%) considered effective for patients, in terms of prevention of treatment discontinuation using a method other than physical restraint. All items and contents were considered useful by more than 60% of the nurses. Considering that the nurses working in the clinical setting reported 93.9% of usefulness, we concluded that this nursing protocol remained valid at a certain level. We also received a comment from the certified nurses that we should include the basic contents for newly graduated nurses. We consider that this nursing protocol will be also useful for newly graduated nurses to acquire knowledge. It helped to standardize nursing care in order to predict potential risks for patients with impaired cognitive function.

Effect of ivabradine in the treatment of acute exacerbation of chronic obstructive pulmonary disease with heart failure

Objective: To observe the effectiveness and safety of ivabradine in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) and heart failure. Methods:Patients who were admitted to hospital with AECOPD during the period from August 2017 to July 2018. Then those both had heart failure with reduced ejection fraction(HFrEF) and a resting heart rate>70 beats/min were enrolled. A total of 86 cases were screened and completed, which were randomly divided into two groups for treatment. The control group(41 cases) received standard treatments, such as oxygen, anti-infection, anti-spasmodic, hormone, diuretic, ACEI/ARB, recombinant human brain natriuretic peptide (rhBNP), etc. The bisoprolol was given 2.5~5 mg orally once a day to control heart rate, and the test group(45 cases) was further treated with ivabradine 2.5~5 mg orally twice a day on the basis of the control group. The average heart rate, cardiac function, lung function, and 6-minute walking test were compared between the two groups. Results: After treatment, the average heart rate of the test group was lower than the control group, and the heart rate control rate(<70 beats/min%) of the test group was superior to the control group. The level of N-terminal B-type natriuretic peptide(NT-proBNP) in test group was significantly lower than that in control group. The distance of the 6-minute walking test in e test group was significantly longer than that in control group. Conclusion: Ivabradine combined with bisoprolol could help patients with AECOPD and heart failure to further reduce the heart rates, improve heart function and exercise tolerance. Moreover, the therapeutic safety was acceptable during the short term.

A very high frequency index of heart rate variability for evaluation of left ventricular systolic function and prognosis in chronic heart failure patients using five-minute electrocardiogram

Objective A novel index based on fi-equency-domain analysis of heart rate variability （HRV） was tested on patients with reduced left ventricular systolic function. This index, namely VHFI, was defined as the very high frequency （VHF） component of the power spectrum normalized to represent its relative value in proportion to the total power minus the very low frequency component. Methods Patients （n = 130） were divided into a study group, consisting 66 patients with decreased left ventricular systolic function, and a control group, consisting 64 patients with normal heart structure and function and without severe coronary artery stenosis （〈 50%）. Results VHFI in the study group was significantly higher than that in the control group （19.17 ± 13.35 vs 11.37 ± 10.77, P 〈 0.001）. Cardiac events occurred in 18 patients during follow-up （33.34 i 3.26 months）. Defining the positive test as VHFI =15 and negative test as VHFI 〈15, achieved a sensitivity of 57.58% and a specificity of78.13% for predicting decreased left ventricular systolic function, and achieved a sensitivity of 66.67% and a specificity of 64.29% for predicting cardiac events. Univariate Cox regression analysis showed that positive VHFI test was an independent variable in predictive cardiac events. Conclusions The results suggest that VHFI is a useful tool for quick evaluation of left ventricular systolic function and prediction of prognosis

Development of a Nursing Protocol for Hospitalized Patients with Reduced Cognitive Function in the Process of Recovery from Acute Exacerbation of Chronic Heart Failure

The purpose of this study is to develop a nursing protocol aiming at early recovery of hospitalized patients with reduced cognitive functions in the process of recovery from acute exacerbation of chronic heart failure. At the first stage of the research, a draft nursing protocol was prepared based on a basic survey. At the second stage of research, a semi-structured interview was conducted for 4 nurses certified for chronic heart failure nursing and 11 nurses certified for dementia nursing so as to ensure content validity of the draft nursing protocol. At the third stage of the study, the possibility of clinical application of the nursing protocol revision plan proposed at the second stage of the study was examined. The nursing protocol revision plan was effective for 118 nurses (90.1%) who carried out the protocol for the target patient on assessment items, essential points of nursing care and specific nursing care. There were no items or contents for which confirmation of usefulness was less than 60%. Since 90.1% of the usefulness was confirmed by nurses working in the actual clinical setting, the authors believe that this nursing protocol was secured to a certain level. The nursing protocol developed in this study has been requested by nurses at clinical sites in the past. It is very meaningful in improving nursing for the early recovery of hospitalized patients with reduced cognitive function in the process of recovery from acute exacerbation of chronic heart failure.

The Lebanese Society of Cardiology Consensus Statement on the Use of Natriuretic Peptides for the Management of Heart Failure

Plasma concentration of Natriuretic Peptide (NP) is a valuable diagnostic tool for heart failure (HF). It can help rule out or confirm a diagnosis of HF based on symptoms, but its use is not clearly defined. NPs should be used in conjunction with physical examination and other diagnostic tests. However, it is important to note that several conditions besides the diagnosis of HF may cause NPs levels to be elevated. Additionally, there are situations when NP concentrations may be below diagnostic thresholds in [1]. This consensus statement aims to provide a straightforward diagnostic flowchart for clinicians in both the emergency department and outpatient settings to aid in diagnosing both acute and chronic HF. The diagnosis of acute HF can be ruled out with a BNP level of 100 pg/mL or NTproBNP level of 300 pg/mL, regardless of the patient’s age. To identify HF, a 3-level cut-off point based on the patient’s age is recommended. Chronic heart failure can be ruled out with a BNP level of 35 pg/mL or NTproBNP level of 125 pg/mL, regardless of thepatient’s age [1].

Repeated measurement of growth-differentiation factor-15in Chinese Han patients with post-myocardial infarction chronic heart failure

Background Growth-differentiation factor-15(GDF-15)is a promising prognostic biomarker in patients with chronic heart failure (CHF).Comparatively little is known about the value of repeated measurement of GDF-15with CI-IF in Chinese Han population.This study sought to identify the clinical value of repeated measurement of GDF-15in Chinese Han patients with post-myocardial infarction CHF. Methods In total,232consecutive Chinese Hart patients with post-myocardial infarction CHF were enrolled prospectively from January 2014to June 2016.The plasma concentration of GDF-15was determined on admission and over 12months.Patients were followed up for all-cause death and a composite outcome of major adverse cardiac events (MACE)included all-cause death,myocardial infarction and first heart failure (HF)re-hospitalization.Association with other clinical variables and adverse outcomes of repeated measurement of GDF-15 was explored.Results The median baseline GDF-15level was 2025ng/L.Baseline GDF-15was moderately associated with baseline N-terminal pro-B type nalriuretic peptide (NT-proBNP)(coefficient 0.561,P <0.001).During a median follow-up of 20months,there were 53deaths and 100MACE.GDF-I5remained an independent predictor of all-cause death (adjusted hazard ratio 1.826per 1Ln U,95%CI: 1.037-8.360;P =0.037)and MACE (adjusted hazard ratio 2.243per I Ln U,95%CI:1.181-1.775;P <0.001)adjusted for established risk factors.Repeated measurement of GDF-15was performed in 173survivals over 12months.Increase of GDF-15over 12months was associ- ated with dilatation of left ventricle and acted as an independent predictor of subsequent all-canse death (adjusted HR =3.164,95%CI: 1.245~.041;P =0.015).In the joint model,GDF-15was also shown to be a risk factor for all-cause death (HR =2.749,95%CI: 1.667-3.831;P <0.001)and MACE (FIR =2.434,95%CI:1.425-3.443;P <0.001).Conclusions Repeated measurements of GDF-15 have promising prognostic value of the risk of all-cause death in Chinese Han patients with CI-IF post-myocardial infarction.GDF-15may influence the post-myocardial infarction CI-IF through the path physiological pathway of myocardial remodeling.

Heart failure and left ventricular dysfunction in older patients with chronic kidney disease: the China Hypertension Survey (2012‒2015)

Background Heart failure(HF)is a leading cause of hospitalization and mortality for older chronic kidney disease(CKD)patients.However,the epidemiological data is scarce.We aimed to determine the prevalence of left ventricular(LV)dysfunction and HF,and to explore the risk factors for HF among those patients.Methods This is a cross-sectional analysis of the China Hypertension Survey conducted between October 2012 and December 2015.A total of 5,808 participants aged≥65 years were included in the analysis.Self-reported history of HF and any other cardiovascular diseases was acquired.2-D and Doppler echocardiography were used to assess LV dysfunction.CKD was defined as either estimated glomerular filtration rate(eGFR)<60 mL/min per 1.73 m2 or urinary albumin to creatinine ratio(ACR)≥30 mg/g.Results Among CKD patients aged≥65 years,the weighted prevalence of HF,heart failure with preserved ejection fraction(HFpEF),heart failure with mid-range ejection fraction(HFmrEF),and heart failure with reduced ejection fraction(HFrEF)was 4.8%,2.5%,0.8%,and 1.7%,respectively.The weighted prevalence of HF was 5.0%in patients with eGFR<60 mL/min per 1.73 m2,and was 5.9%in patients with ACR≥30 mg/g.The prevalence of LV systolic dysfunction was 3.1%,and while it was 8.9%for moderate/severe diastolic dysfunction.Multivariate analysis showed that smoking was significantly associated with the risk of HF.Furthermore,age,smoking,and residents in rural areas were significantly associated with a risk of LV diastolic dysfunction.Conclusions The prevalence of HF and LV dysfunction was high in older patients with CKD,suggesting that particular strategies will be required.

Correlation analysis between lung ultrasound scores and pulmonary arterial systolic pressure in patients with acute heart failure admitted to the emergency intensive care unit

Background:No convenient,inexpensive,and non-invasive screening tools exist to identify pulmonary hypertension(PH)-left heart disease(LHD)patients during the early stages of the disease course.This study investigated whether different methods of lung ultrasound(LUS)could be used for the initial investigation of PH-LHD.Methods:This was a single-center prospective observational study which was performed in the Zigong Fourth People’s Hospital.We consecutively enrolled patients with heart failure(HF)admitted to the emergency intensive care unit from January 2018 to May 2020.Transthoracic echocardiography and LUS were performed within 24 h before discharge.We used the Spearman coefficient for correlation analysis between ultrasound scores and pulmonary arterial systolic pressure(PASP).Bland-Altman plots were generated to inspect possible bias,and receiver operating characteristic(ROC)curves were calculated to assess the relationship between ultrasound scores and an intermediate and high echocardiographic probability of PH-LHD.Results:Seventy-one patients were enrolled in this study,with an overall median age of 79(interquartile range:71.5–84.0)years.Among the 71 patients,36(50.7%)cases were male,and 26(36.6%)had an intermediate and high echocardiographic probability of PH.All four LUS scores in patients with an intermediate and high probability of PH were significantly higher than in patients with a low probability of PH(P<0.05).The correlation coefficient(r)between different LUS scoring methods and PASP was moderate for the 6-zone(r=0.455,P<0.001),8-zone(r=0.385,P=0.001),12-zone(r=0.587,P<0.001),and 28-zone(r=0.535,P<0.001)methods.In Bland-Altman plots,each of the four LUS scoring methods had a good agreement with PASP(P<0.001).The 8-zone and 12-zone methods showed moderately accurate discriminative values in differentiating patients with an intermediate and high echocardiographic probability of PH(P<0.05).
