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.

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.

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.

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.

Heart failure in the elderly

The aging of the population is, currently, a major phenomenon, drawing the attention of a number of investigators. The significant increase of life expectancies over the past few decades, in addition to social and economic consequences, has lead to a major change in the morbidity and mortality profile of elders. Heart failure （HF） is a condition in which the heart can not pump enough blood to meet the body＇s needs. HF is predominantly a disorder of the elderly with rates increasing exponentially. The prevalence of HF approximately doubles with each decade of life. As people live longer, the occurrence of HF rises, as well as other conditions that complicate its treatment. Impaired heart function implies a reduced duration of survival. Fortunately, many factors that can prevent HF and improve outcome are known and can be applied at any stage. This review emphasizes the importance of factors inherent in aging itself, focusing on heart disease, particularly as a disease of aging, can help critically refine management of this acute and chronic disease, as well as foster preventive strategies to reduce the incidence of this common malady.

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.

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.

Respiratory and Cardiac Characteristics of ICU Patients Aged 90 Years and Older:A Report of 12 Cases

Objective To investigate the respiratory and cardiac characteristics of elderly Intensive Care Unit （ICU） patients. Methods Twelve senior ICU patients aged 90 years and older were enrolled in this study. We retrospectively collected all patients＇ clinical data through medical record review. The basic demographics, primary cause for admission, the condition of respiratory and circulatory support, as well as prognosis were recorded. Shock patients and pneumonia patients were specifically analyzed in terms of clinical manifestations, laboratory variables, echocardiography, and lung ultrasound results. Results The mean age of the included patients was 95 years with a male predominance （8 to 4, 66.7%）. Regarding the reasons for admission, 6 （50.0%） patients had respiratory failure, 1 （8.3%） patient had shock, while 5 （41.7%） patients had both respiratory failure and shock. Of the 6 patients who suffered from shock, only 1 was diagnosed with distributive shock, 5 with cardiogenic shock. Of the 5 cardiogenic shock patients, 1 was diagnosed with acute coronary syndrome. The rest 4 cardiogenic shock patients were diagnosed with Takotsubo cardiomyopathy. The patient with ST-segment elevation myocardial infarction died within 24 hours. Of the 4 Takotsubo patients, 1 died on day-6 and the other 3 patients were transferred to ward after heart function recovered in 1 to 2 weeks. Of the 10 pneumonia patients, 3 were diagnosed as community acquired pneumonia, and 7 as hospital acquired pneumonia. Only 3 patients were successfully weaned from ventilator. The others required long-term ventilation complicated with heart failure, mostly with diastolic heart failure. Lung ultrasound of 6 during spontaneous breathing trial. patients with diastolic dysfunction showed bilateral B-lines Conclusions Elderly patients in shock tend to develop Takotsubo cardiomyopathy. Diastolic heartdysfunction might be a major contributor to difficult weaning from ventilator in elderly patients. Bedside lung ultrasonography and echocardiography could help decide the actual cause of respiratory failure and shock more accurately and effectively.

Features and clinical nursing of heart failure in elderly patients during perioperative period

Heart failure is a common condition in elderly patients.With further population aging,incidence of heart failure is constantly increasing.When heart failure occurs in this group of patients,clinical symptoms may vary vastly,rendering difficulty for the treatment process and leading to poor efficacy and prognosis.To gain better under-standing on clinical symptoms and signs of heart failure in elderly patients,to provide prevention and treatment against heart failure for elderly patients in terms of nursing care and to improve success rate of salvage treatment as well as nurs-ing quality.Methods Retrospective analysis was performed in 141 patients with heart failure who were treated in our hospital during January 2005 and December 2009.Those aged > 60 years were assigned to elderly group while those aged < 60 years were assigned to non elderly group.These two groups were compared in terms of clinical symptoms, signs and physical and laboratory examinations.Results Clinical symptoms and signs of heart failure tended to be a-typical in elderly patients.Symptoms including cough,sputum,increased heart rate and mental disorder were frequent, and a substantial proportion of patients had pulmonary congestion and edema.Conclusions Prevention and specific nursing measures should be aggressively taken based on the features of heart failure in elderly patients.Frequency of in-spection particularly observation on atypical symptoms should be increased to provide intensive monitoring.

Follicular lymphoma with cardiac involvement in a 90-year-old patient:A case report

BACKGROUND The incidence of cardiac lymphoma is low,and it mainly occurs secondary to nonHodgkin’s lymphoma,particularly diffuse large B-cell lymphoma.Here,we report a case of follicular lymphoma with cardiac involvement and severe heart failure as the sole clinical manifestation.CASE SUMMARY A 90-year-old male patient was first admitted to our hospital due to an accidentally discovered painless mass in the right lower abdomen.A biopsy of the mass revealed a follicular lymphoma.Positron emission tomography-computed tomography confirmed mild pericardial effusion,and echocardiography showed no structural abnormalities with normal ejection fraction at the time of diagnosis.The patient refused our recommendation of chemotherapy and was re-admitted 4 mo later due to heart failure.A series of subsequent echocardiographic examinations showed thickening of the left ventricular walls and increasing pericardial effusion over the following 2 mo.His heart failure exacerbated despite all symptomatic and supportive treatments.He passed away after an episode of aspiration pneumonia.CONCLUSION The diagnosis of cardiac lymphoma is difficult as its clinical manifestations are nonspecific,and prognosis is poor.
