Effects of health concept model-based detailed behavioral care on mood and quality of life in elderly patients with chronic heart failure

BACKGROUND With the intensification of social aging,the susceptibility of the elderly population to diseases has attracted increasing attention,especially chronic heart failure(CHF)that accounts for a large proportion of the elderly.AIM To evaluate the application value of health concept model-based detailed behavioral care in elderly patients with CHF.METHODS This study recruited 116 elderly CHF patients admitted from October 2018 to October 2020 and grouped them according to the nursing care that they received.The elderly patients who underwent health concept model-based detailed behavioral care were included in a study group(SG;n=62),and those who underwent routine detailed behavioral nursing intervention were included as a control group(CG;n=54).Patients’negative emotions(NEs),quality of life(QoL),and nutritional status were assessed using the self-rating anxiety/depression scale(SAS/SDS),the Minnesota Living with Heart Failure Questionnaire(MLHFQ),and the Modified Quantitative Subjective Global Assessment(MQSGA)of nutrition,respectively.Differences in rehabilitation efficiency,NEs,cardiac function(CF)indexes,nutritional status,QoL,and nursing satisfaction were comparatively analyzed.RESULTS A higher response rate was recorded in the SG vs the CG after intervention(P<0.05).After care,the left ventricular ejection fraction was higher while the left ventricular end-diastolic dimension and left ventricular end systolic diameter were lower in the SG compared with the CG(P<0.05).The post-intervention SAS and SDS scores,as well as MQSGA and MLHFQ scores,were also lower in the SG(P<0.05).The SG was also superior to the CG in the overall nursing satisfaction rate(P<0.05).CONCLUSION Health concept model-based detailed behavioral care has high application value in the nursing care of elderly CHF patients,and it can not only effectively enhance rehabilitation efficiency,but also mitigate patients’NEs and improve their CF and QoL.

Objective:To evaluate the efficacy of emergency ventilator therapy in severe acute left heart failure.Methods:A total of 75 patients with severe acute left ventricular heart failure who were admitted to the hospital from July 2020 to July 2023 were randomly divided into two groups.Group A received additional emergency ventilator treatment,and group B received conventional treatment.The efficacy was compared.Results:The curative effect of patients with severe acute left heart failure in group A was higher than that in group B(P<0.05);all blood gas indicators in group A were better than those in group B(P<0.05);all vital signs indicators in group A were better than those in group B(P<0.05);group A was more satisfied with the treatment of severe acute left ventricular heart failure than group B(P<0.05).Conclusion:Patients with severe acute left heart failure who receive emergency ventilator treatment can stabilize vital signs,improve blood oxygen supply,and enhance curative effect.

Neutrophil-to-lymphocyte ratio compared to N-terminal pro-brain natriuretic peptide as a prognostic marker of adverse events in elderly patients with chronic heart failure

Background The neutrophil-to-lymphocyte （N/L） ratio has been associated with poor prognosis in patients with heart failure, but it has not been compared with N-terminal pro-brain natriuretic peptide （NT-proBNP） in elderly patients with chronic heart failure （CHF）. We sought to make this comparison. Methods A total of 1355 elderly patients with CHF were analyzed. A multivariate logistic regression model was used to analyze the variables associated with atrial fibrillation （AF）. Cox regression analysis was used to assess the multivariable rela- tionship between the N/L ratio, NT-proBNP level, and subsequent major cardiovascular events （MCE）. Results In the multiple logistic regression analysis, the N/L ratio was demonstrated as a risk factor for AF in elderly patients with CHF [odds ratio （OR）： 1.079, 95% confi- dence interval （CI）： 1.027-1.134, P = 0.003]. The median follow-up period was 18 months. In a multivariable model using tertiles of both variables, the highest tertile of the N/L ratio was significantly associated with MCE [hazard ratio （HR）： 1.407, 95% CI： 1.098-1.802, P = 0.007] compared with the lowest tertile. Similarly, the highest NT-proBNP tertile was also significantly associated with MCE （HR： 1.461, 95% CI： 1.104-1.934, P- 0.008）. Conclusions In elderly patients with CHF, the N/L ratio is one of the important risk factors for AF and it is an inexpensive and readily available marker with similar independent prognostic power to NT-proBNP. The risk of MCE increases 1.407-fold when the N/L ratio is elevated to the highest tertile.

Additive Benefits of Twice Forest Bathing Trips in Elderly Patients with Chronic Heart Failure

Chronic heart failure （CHF）, a clinical syndrome resulting from the consequences of various cardiovascular diseases （CVDs）, is increasingly becoming a global cause of morbidity and mortality. We had earlier demonstrated that a 4-day forest bathing trip can provide an adjunctive therapeutic influence on patients with CHF. To further investigate the duration of the impact and the optimal frequency of forest bathing trips in patients with CHF, we recruited those subjects who had experienced the first forest bathing trip again after 4 weeks and randomly categorized them into two groups, namely, the urban control group （city） and the forest bathing group （forest）. After a second 4-day forest bathing trip, we observed a steady decline in the brain natriuretic peptide levels, a biomarker of heart failure, and an attenuated inflammatory response as well as oxidative stress. Thus, this exploratory study demonstrated the additive benefits of twice forest bathing trips in elderly patients with CHF, which could further pave the way for analyzing the effects of such interventions in CVDs.

Beta-blocker therapy in elderly patients with renal dysfunction and heart failure

OBJECTIVE To assess the role of beta-blockers(BB)in patients with chronic kidney disease(CKD)aged≥75 years.METHODS AND RESULTS From January 2008 to July 2014,we included 390 consecutive patients≥75 years of age with ejection fraction≤35%and glomerular filtration rate(GFR)≤60 m L/min per 1.73 m^2.We analyzed the relationship between treatment with BB and mortality or cardiovascular events.The mean age of our population was 82.6±4.1 years.Mean ejection fraction was 27.9%±6.5%.GFR was 60-45 m L/min per 1.73 m^2 in 50.3%of patients,45-30 m L/min per 1.73 m^2 in 37.4%,and<30 m L/min per 1.73 m^2 in 12.3%.At the conclusion of follow-up,67.4%of patients were receiving BB.The median follow-up was28.04(IR:19.41-36.67)months.During the study period,211 patients(54.1%)died and 257(65.9%)had a major cardiovascular event(death or hospitalization for heart failure).BB use was significantly associated with a reduced risk of death(HR=0.51,95%CI:0.35-0.74;P<0.001).Patients receiving BB consistently showed a reduced risk of death across the different stages of CKD:stage IIIa(GFR=30-45 m L/min per 1.73 m^2;HR=0.47,95%CI:0.26-0.86,P<0.0001),stage IIIb(GFR 30-45 m L/min per 1.73 m^2;HR=0.55,95%CI:0.26-1.06,P=0.007),and stages IV and V(GFR<30 m L/min per 1.73 m~2;HR=0.29,95%CI:0.11-0.76;P=0.047).CONCLUSIONS The use of BB in elderly patients with HFr EF and renal impairment was associated with a better prognosis.Use of BB should be encouraged when possible.

Prevalence of iron deficiency in patients aged 75 years or older with heart failure

Background The latest studies presented at the American Heart Association (AHA) meeting on heart failure and the update of the European Cardiology Society’s (ECS) recommendations on heart failure in 2016 recommend intravenous iron supplementation in patients with heart failure, reduced ejection fraction and iron deficiency for improves walking performance and quality of life, and reduces morbidity. In the present study, we investigated the prevalence of iron deficiency in heart failure patients aged 75 years or older, as there is currently no data on these patients. Methods We performed an observational study on hospitalized patients in Geriatric Cardiology Department. Among the 462 patients hospitalized during eight months, 176 were eligible for inclusion;22 patients was significant interference with an inflammatory syndrome (high ferritin with high C-reactive protein), and for 13 patients iron-related data were not available. For each patient included, a complete iron assessment and type of heart failure was available. Results A total of 141 patients were included, the mean age was 88 years (range: 75–101), and there were 52 (36.9%) of patients with reduced ejection fraction (EF), 37 (26.2%) with mid-range EF, and 52 (36.9%) with preserved EF. Irrespective of heart failure type, 73.8% had iron deficiency (95% CI: 65.7%–80.8%);this was found in 57.7%(95% CI: 43.2%–71.3%) of those with reduced EF, 78.4%(95% CI: 61.8%–90.2%) of those with mid-range EF, and 86.5%(95% CI: 74.2%–94.4%) of those with preserved EF (P = 0.003). Conclusion The prevalence of iron deficiency was very high in very elderly patients with heart failure, especially those with HF with mid-range EF or HF with preserved EF.

A Pregnant Patient with Aortic Regurgitation and Symptoms of Acute Heart Failure Caused by Peripartum Cardiomyopathy: A Case Report

Introduction: Knowledge of the risks of pregnancy with heart disease is important because the maternal mortality is much higher than the average. Peripartum cardiomyopathy (PPCM) is rare but it is one of major causes of maternal death. We experienced a pregnant patient with severe aortic regurgitation (AR) presented symptoms of acute heart failure. Her heart failure was not better after an emergency cesarean section and aortic valve replacement (AVR) therefore we think that PPCM caused her heart failure. Case presentation: A 35-year-old woman diagnosed as having severe AR became pregnant. No changes in the AR were apparent during pregnancy. However, the patient developed symptoms of acute heart failure at 37 weeks of gestation, and an emergency cesarean section was performed under general anesthesia. Her hemodynamic status worsened after the cesarean section, and AVR was performed. She was supported with percutaneous cardiopulmonary support (PCPS) after the operation. As recovery seemed to take longer than usual, we decided to implant a ventricular assist device (VAD). Her condition improved after VAD placement, but then she died from a cerebral infarction. In this case, the heart failure was an acute-onset even though AR was stable before and after the pregnancy, and the heart failure did not improve after AVR. Therefore, we concluded that PPCM, rather than AR caused her heart failure. Conclusions: We encountered a case of a pregnant patient with severe AR who presented with symptoms of acute heart failure caused by PPCM. The effect of AR to her heart failure could not be easily denied. This delayed the diagnosis of PPCM, which in turn delayed our decision to use a VAD. Therefore, PPCM should be considered when pregnant patients with heart disease present symptoms of heart failure.

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).

Precipitating factors leading to decompensation of chronic heart failure in the elderly patient in South-American community hospital

Background Exacerbations of heart failure appear frequently associated with precipitating factors not directly related to the evolution of cardiac disease. There still a paucity of data on the proportional distribution of precipitating factors specifically in elderly patients. The aim of this study was to examine prospectively the precipitating factors leading to hospitalization in elderly patients with heart failure in our community hospital. Methods We evaluate elderly patients who need admissions for decompensate heart failure. All patients were reviewed daily by the study investigators at the first 24 h and closely followed-up. Decompensation was defined as the worsening in clinical NYHA class associated with the need for an increase in medical treatment （at minimum intravenously diuretics）. Results We included 102 patients （mean age 79 ± 12 years）. Precipitating factors were identified in 88.5%. The decompensation was sudden in 35% of the cases. Noncompliance with diet was identified in 52% of the patients, lack of adherence to the prescribed medications amounted to 30%. Others precipitating factors were infections （29%）, arrhythmias （25%）, acute coronary ischemia （22%）, and uncontrolled hypertension （15%）, miscellaneous causes were detected in 18% of the cases （progression of renal disease 60%, anemia 30% and iatrogenic factors 10%）. Concomitant cause was not recognizable in 11.5%. Conclusions Large proportion heart failure hospitalizations are associated with preventable precipitating factors. Knowledge of potential precipitating factors may help to optimize treatment and provide guidance for patients with heart failure. The presence of potential precipitating factors should be routinely evaluated in patients presenting chronic heart failure.

Left ventricular assist devices as destination therapy in stage D heart failure

1 Introduction? Mechanical circulatory support (MCS) has increasingly become an important management opportunity for patients with stage D heart failure (HF) with remarkable impact on patient survival and quality of life. Early clinical trials have demonstrated improved outcomes of durable left ventricular assist device (LVAD) support compared with optimal medical management.[1] As technology advanced, continuous flow LVADs outperformed pulsatile flow devices in clinical trials and the field migrated to HeartMate (Abbott Laboratories, Abbott Park, IL) and HeartWare (Medtronic, Minneapolis, MN) devices due to their clinical superiority. Among the continuous flow devices.

Diastolic heart failure in the elderly

Heart failure with preserved left ventricular function is a common problem among elderly patients. Given that diastolic heart failure (DHF) occurs in up to 50% of all heart failure admissions, and that incidence increases with age, knowledge of current recommendations for its diagnosis and treatment are extremely important for the elderly population. Causes of DHF include the aging process itself, hypertension, left ventricular hypertrophy, aortic stenosis, and hypertrophic obstructive cardiomyopathy. The patient with DHF may present with signs and symptoms similar to those observed in systolic heart failure. Treatment goals for the patient with DHF include achieving normal volume status, improving relaxation of the left ventricle, regression of hypertrophy if possible, and management of any co-morbidities that may aggravate the clinical status of patients with DHF. Hopefully, in the future, further data from randomized clinical trials will allow a more defined approach to care in these patients.

Heart failure in the elderly-some aspects in pathophysiology,diagnosis and therapy that require special attention

Approximately 50% of all heart failure patients in the US are above 75 years of age, which is almost similar to most European countries and the Middle and the Far East. Even though aging is an independent molecular process with a multitude of genetic predetermination and biochemical mediations, aging itself does not automatically result in cardiac insufficiency. On the other hand, with increasing age, cardioprotective mechanisms in response to stress are lost, and progressive cardiomyocyte degeneration with replace- ment fibrosis is often seen in older hearts, even though the exact triggers are not completely understood. Older patients with heart failure have distinct features that require special attention in diagnosis as well as therapy. The elderly more frequently suffer from multiple co-morbidities and might have atypical clinical presentations. Several precautions are essential in the treatment of heart failure in the elderly due to co-existing morbidities and the pharmacokinetic and pharmacodynamic changes related to increased age. Also, treatment expectations, compliance, mental status and cognitive function might play a major role regarding optimized treatment and monitoring options in the elderly suffering from heart failure. This review summarizes current issues of heart failure management in the elderly.

Cardiac resynchronization therapy in the elderly heart failure patient

Ms. BP is an 83 year old white female with a long history of congestive heart failure (HF). She is now symptomatic with minimal exertion, has a left ventricular ejection fraction (LVEF) of 20%. Her CHF is due to hypertension (HTN) plus coronary artery disease (CAD) and she is on angiotensin converting enzyme inhibitor (ACEI), furosemide, digoxin,spironolactone, low dose beta blocker and nitrates. Her beta-natriuretic peptide (BNP) in clinic is 3030 pg/ml, heart rate (HR) 100, blood pressure (BP) 89/43.

Management of chronic heart failure in the older population

Chronic heart failure （CHF） is the leading cause of hospitalization for those over the age of 65 and represents a significant clinical and economic burden. About half of hospital re-admissions are related to co-morbidities, polypharmacy and disabilities associated with CHF. Moreover, CHF also has an enormous cost in terms of poor prognosis with an average one year mortality of 33%–35%. While more than half of patients with CHF are over 75 years, most clinical trials have included younger patients with a mean age of 61 years. Inadequate data makes treatment decisions challenging for the providers. Older CHF patients are more often female, have less cardiovascular diseases and associated risk factors, but higher rates of non-cardiovascular conditions and diastolic dysfunction. The prevalence of CHF with reduced ejection fraction, ischemic heart disease, and its risk factors declines with age, whereas the prevalence of non-cardiac co-morbidities, such as chronic renal failure, dementia, anemia and malignancy increases with age. Diabetes and hypertension are among the strongest risk factors as predictors of CHF particularly among women with coronary heart disease. This review paper will focus on the specific consideration for CHF assessment in the older population. Management strategies will be reviewed, including non-pharmacologic, pharmacologic, quality care indicators, quality improvement in care transition and lastly, end-of-life issues. Palliative care should be an integral part of an interdiscipli-nary team approach for a comprehensive care plan over the whole disease trajectory. In addition, frailty contributes valuable prognostic in-sight incremental to existing risk models and assists clinicians in defining optimal care pathways for their patients.
