Aims and objectives

This study aimed to evaluate Tai Chi group training among patients with chronic heart failure (CHF) aged 70 years and older.

Background

Physical activity is recommended for CHF treatment. Tai Chi is found to be beneficial to different patient groups, although few studies focus on older patients with CHF.

Design

A mixed methods study. Participants were randomly assigned to Tai Chi training twice a week for 16 weeks (= 25) or control (= 20). Quantitative data were collected at baseline, at the end of the training period and 6 months after training, assessing self-rated fatigue and quality of life, natriuretic peptides and physical performance. Individual qualitative interviews were conducted with participants (= 10) in the Tai Chi training group.

Results

No statistical differences between the Tai Chi training group and the control group in quality of life or natriuretic peptides was found. After 16 weeks, the training group tended to rate more reduced activity and the control group rated more mental fatigue. Participants in the training group rated increased general fatigue at follow-up compared with baseline. Qualitative interviews showed that Tai Chi training was experienced as a new, feasible and meaningful activity. The importance of the leader and the group was emphasized. Improvements in balance were mentioned and there was no physical discomfort.

Conclusion

Tai Chi was experienced as a feasible and meaningful form of physical exercise for patients with CHF aged over 70 years despite lack of achieved health improvement. Further investigations, using feasibility and meaningfulness as outcome variables seems to be useful.

Abstract [en]

BACKGROUND: The complex needs of people with chronic heart failure (HF) place great demands on their family members, and it is important to ask family members about their perspectives on the quality of HF care.

OBJECTIVE: To describe family members' perceptions of quality of HF care in an outpatient setting.

METHODS: A cross-sectional study using a short form of the Quality from Patients' Perspective (QPP) questionnaire for data collection. The items in the questionnaire measure four dimensions of quality, and each item consists of both the perceived reality of the care and its subjective importance. The study included 57 family members of patients with severe HF in NYHA class III-IV.

RESULTS: Family members reported areas for quality improvements in three out of four dimensions and in dimensionless items. The lowest level of perceived reality was reported for treatment for confusion and loss of appetite. Treatment for shortness of breath, access to the apparatus and access to equipment necessary for medical care were the items with the highest subjective importance for the family members.

CONCLUSION: Family members identified important areas for quality improvement in the care for patients with HF in an outpatient setting. In particular, symptom alleviation, information to patients, patient participation and access to care were identified as areas for improvements. Thus, measuring quality from the family members' perspective with the QPP might be a useful additional perspective when it comes to the planning and implementation of changes in the organisation of HF care.

Abstract [en]

Observational studies indicate that low-density lipoprotein (LDL) cholesterol acts as a primary contributor to an active process leading to aortic stenosis (AS) development. However, randomized clinical trials have failed to demonstrate an effect of lipid lowering on impeding AS progression. This study explored if pretreatment LDL levels and AS severity altered the efficacy of lipid-lowering therapy. The study goal was evaluated in the analysis of surviving patients with baseline data in the Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) trial of 1,873 asymptomatic patients with mild-to-moderate AS. Serially measured peak aortic jet velocity was the primary effect estimate. Linear mixed model analysis adjusted by baseline peak jet velocity and pretreatment LDL levels was used to assess effect modifications of treatment. Data were available in 1,579 (84%) patients. In adjusted analyses, lower baseline peak aortic jet velocity and higher pretreatment LDL levels increased the effect of randomized treatment (p >= 0.04 for interaction). As such, treatment impeded progression of AS in the highest quartile of LDL among patients with mild AS at baseline (0.06 m/s per year slower progression vs placebo in peak aortic jet velocity, 95% confidence interval 0.01 to 0.11, p = 0.03), but not in the 3 other quartiles of LDL. Conversely, among patients with moderate AS, there was no detectable effect of treatment in any of the pretreatment LDL quartiles (all p In conclusion, in a non prespecified post hoc analysis, the efficacy of lipid-lowering therapy on impeding AS progression increased with higher pretreatment LDL and lower peak aortic jet velocity (SEAS study: NCT00092677).

Abstract [en]

Background and aims: Soluble urokinase plasminogen activator receptor (suPAR) is an inflammatory marker associated with cardiovascular disease. Statins lower both low-density lipoprotein (LDL)-cholesterol and C-reactive protein (CRP), resulting in improved outcomes. However, whether lipid-lowering therapy also lowers suPAR levels is unknown.& para;& para;Methods: We investigated whether treatment with Simvastatin 40 mg and Ezetimibe 10 mg lowered plasma suPAR levels in 1838 patients with mild-moderate, asymptomatic aortic stenosis, included in the Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) study, using a pattern mixture model. A 1-year Cox analysis, adjusted for established cardiovascular risk factors, allocation to study treatment, peak aortic valve velocity and baseline suPAR, was performed to evaluate relationships between change in suPAR with all-cause mortality and the composite endpoint of major cardiovascular events (MCE) composed of ischemic cardiovascular events (ICE) and aortic valve related events (AVE).& para;& para;Results: After 4.3 years of follow-up, suPAR levels had increased by 9.2% (95% confidence interval [CI]: 7.0%-11.5%) in the placebo group, but only by 4.1% (1.9%-6.2%) in the group with lipid-lowering treatment (p<0.001). In a multivariate 1-year analysis, 1-year suPAR was strongly associated with all-cause mortality, hazard ratio (HR) = 2.05 (1.17-3.61); MCE 1.40 (1.01-1.92); and AVE 1.42 (1.02-1.99) (all p<0.042) for each doubling of suPAR; but was not associated with ICE.& para;& para;Conclusions: Simvastatin and Ezetimibe treatment impeded the progression of the time-related increase in plasma suPAR levels. Year-1 suPAR was associated with all-cause mortality, MCE, and AVE irrespective of baseline levels (SEAS study: NCT00092677). (C) 2018 Elsevier B.V. All rights reserved.

Abstract [en]

Objective: Chronic heart failure is a disease with high morbidity and symptom burden for patients, and it also places great demands on family members. Patients with heart failure should have access to palliative care for the purpose of improving quality of life for both patients and their families. In the PREFER randomized controlled intervention, patients with New York Heart Association classes III–IV heart failure received person-centered care with a multidisciplinary approach involving collaboration between specialists in palliative and heart failure care. The aim of the present study was to describe family members' experiences of the intervention, which integrated palliative advanced home and heart failure care.

Method: This study had a qualitative descriptive design based on family member interviews. Altogether, 14 family members participated in semistructured interviews for evaluation after intervention completion. The data were analyzed by means of content analysis.

Results: Family members expressed gratitude and happiness after witnessing the patient feeling better due to symptom relief and empowerment. They also felt relieved and less worried, as they were reassured that the patient was being cared for properly and that their own responsibility for care was shared with healthcare professionals. However, some family members also felt as though they were living in the shadow of severe illness, without receiving any support for themselves.

Significance of results: Several benefits were found for family members from the PREFER intervention, and our results indicate the significance of integrated palliative advanced home and heart failure care. However, in order to improve this intervention, psychosocial professionals should be included on the intervention team and should contribute by paying closer attention and providing targeted support for family members.

Abstract [en]

Background: A new biomarker, suppression of tumorigenicity 2 (ST2) has been introduced as a marker for fibrosis and hypertrophy. Its clinical value in comparison with N-terminal pro-hormone of brain natriuretic peptide /Amino-terminal pro-B-type natriuretic peptide (NTproBNP) in predicting mortality in elderly patients with symptoms of heart failure (HF) is still unclear.

Aim: To evaluate the prognostic value for all-cause- and cardiovascular mortality of ST2 or NTproBNP and the combination of these biomarkers.

Patients and methods: One hundred seventy patients patients with clinical symptoms of HF (77 (45%) were with verified HF) were recruited from one selected primary health care center (PHC) in Sweden and echocardiography was performed in all patients. Blood samples were obtained from 159 patients and stored frozen at -70 degrees C. NTproBNP was analyzed at a central core laboratory using a clinically available immunoassay. ST2 was analyzed with Critical Diagnostics Presage ST2 ELISA immunoassay.

Results: We studied 159 patients (mean age 778.3years, 70% women). During ten years of follow up 78 patients had died, out of which 50 deaths were for cardiovascular reasons. Continuous NTproBNP and ST2 were both significantly associated with all-cause mortality (1.0001; 1.00001-1.0002, p=0.04 and 1.03; 1.003-1.06, p=0.03), NTproBNP but not ST2 remained significant for cardiovascular mortality after adjustments (1.0001; 1.00001-1.0002, p=0.03 and 1.01; 0.77-1.06, p=0.53), respectively. NTproBNP above median (>328ng/L) compared to below median was significantly associated with all-cause mortality(HR: 4.0; CI :2.46-6.61; p<0.001) and cardiovascular mortality (HR: 6.1; CI: 3.11-11.95; p<0.001). Corresponding analysis for ST2 above median (25.6ng/L) was not significantly associated neither with all-cause mortality (HR; 1.4; CI: 0.89-2.77) nor cardiovascular mortality (HR: 1.3; CI: 0.73-2.23) and no significant interaction of NTproBNP and ST2 (OR: 1.1; CI: 0.42-3.12) was found.

Conclusion: In elderly patients with symptoms of heart failure ST2 was not superior to NTproBNP to predict all cause or cardiovascular mortality. Furthermore, it is unclear if the combination of ST2 and NTproBNP will improve long-term prognostication beyond what is achieved by NTproBNP alone.

Abstract [en]

Background We evaluated whether early measurement of soluble urokinase plasminogen activator receptor (suPAR) could predict future risk of postoperative complications in initially asymptomatic patients with mild-moderate aortic stenosis (AS) undergoing aortic valve replacement (AVR) surgery.

Methods Baseline plasma suPAR levels were available in 411 patients who underwent AVR surgery during in the Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) study. Cox analyses were used to evaluate suPAR in relation to all-cause mortality and the composite endpoint of postoperative complications (all-cause mortality, congestive heart failure, stroke and renal impairment) occurring in the 30-day postoperative period.

Results Patients with initially higher levels of suPAR were at increased risk of postoperative mortality with a HR of 3.5 (95% CI 1.4 to 9.0, P=0.008) and postoperative complications with a HR of 2.7 (95% CI 1.5 to 5.1, P=0.002), per doubling in suPAR. After adjusting for the European System for Cardiac Operative Risk Evaluation or Society of Thoracic Surgeons risk score, suPAR remained associated with postoperative mortality with a HR 3.2 (95% CI 1.2 to 8.6, P=0.025) and 2.7 (95% CI 1.0 to 7.8, P=0.061); and postoperative complications with a HR of 2.5 (95% CI 1.3 to 5.0, P=0.007) and 2.4 (95% CI 1.2 to 4.8, P=0.011), respectively.

Conclusion Higher baseline suPAR levels are associated with an increased risk for postoperative complications and mortality in patients with mild-moderate, asymptomatic AS undergoing later AVR surgery. Further validation in other subsets of AS individuals are warranted.

Abstract [en]

Background: Heart failure is a disease with high morbidity, mortality, and physical and psychological burden. More knowledge about the care provided for patients with heart failure close to death is needed.

Objective: The aim was to describe key aspects of palliative care during the last week of life in patients with heart failure, as reported by healthcare professionals.

Design: This is a national register study.

Setting/Subjects: The study included 3981 patients with diagnosed heart failure as the underlying cause of death.

Measurements: Data were obtained from the Swedish Register of Palliative Care, a national quality register that focuses on patients’ last week of life, independent of diagnosis or care setting. The register includes information about care interventions connected with key aspects of palliative care. Data are reported retrospectively by a nurse or physician at the healthcare unit where the patient dies.

Results: Only 4.2% of patients with heart failure received specialized palliative care. In their last week of life, symptom prevalence was high, validated scales were seldom used, and symptoms were unsatisfactorily relieved. Around one-fifth (17%) of the patients in the study died alone. Less than half of family members had been offered bereavement support (45%). Moreover, one-third (28%) of the patients and more than half (61%) of the family members were reported to have had end-of-life discussions with a physician during the illness trajectory.

Conclusion: The results indicate inadequate palliative care for patients with heart failure during their last week of life.

Abstract [en]

AIM: The purpose of this study was to describe clients and occupational therapists (OTs) experiences of a home-based programme focusing energy conservation strategies (ECS) for clients with chronic heart failure (CHF).

METHODS: The programme, based on occupational therapy intervention process model (OTIPM), was led by two OTs in primary health care. Five clients' self-reported activities of daily living (ADL), fatigue, depression, goal achievements and use of ECS. Furthermore, both clients and OTs were individually interviewed.

RESULTS: The clients reported mild depression, severe fatigue and both increased and decreased independence in ADL. Most goals were achieved, and multiple ECS were used. Clients perceived that they worked collaboratively with the OTs and gained professional support to enhance daily activities. The OTs experienced knowledge and structure and found benefits from the programme, but doubted the possibility of using it in clinical practice.

CONCLUSIONS: This study, despite having few participants, indicates that both the OTs and the clients experienced that the specialized programme gave structure to the OTs work, provided knowledge about CHF and valuable energy conservation strategies. The programme supported the OTs in working in a more comprehensive client-centred way. However, its feasibility needs to be further evaluated.
