A randomized controlled trial on the impact of moderate-intensity continuous aerobic exercise on the depression status of middle-aged patients with congestive heart failure

The Impact of an Electronic Best Practice Advisory on Patients' Physical Activity and Cardiovascular Risk Profile

BACKGROUND

Regular physical activity (PA) is a component of cardiovascular health and is associated with a lower risk of cardiovascular disease (CVD). However, only about half of US adults achieved the current PA recommendations.

OBJECTIVE

The study purpose was to implement PA counseling using a clinical decision support tool in a preventive cardiology clinic and to assess changes in CVD risk factors in a sample of patients enrolled over 12 weeks of PA monitoring.

METHODS

This intervention, piloted for 1 year, had 3 components embedded in the electronic health record: assessment of patients' PA, an electronic prompt for providers to counsel patients reporting low PA, and patient monitoring using a Fitbit. Cardiovascular disease risk factors included PA (self-report and Fitbit), body mass index, blood pressure, lipids, and cardiorespiratory fitness assessed with the 6-minute walk test. Depression and quality of life were also assessed. Paired t tests assessed changes in CVD risk.

RESULTS

The sample who enrolled in the remote patient monitoring (n = 59) were primarily female (51%), White adults (76%) with a mean age of 61.13 ± 11.6 years. Self-reported PA significantly improved over 12 weeks ( P = .005), but not Fitbit steps ( P = .07). There was a significant improvement in cardiorespiratory fitness (469 ± 108 vs 494 ± 132 m, P = .0034), and 23 participants (42%) improved at least 25 m, signifying a clinically meaningful improvement. Only 4 participants were lost to follow-up over 12 weeks of monitoring.

CONCLUSIONS

Patients may need more frequent reminders to be active after an initial counseling session, perhaps getting automated messages based on their step counts syncing to their electronic health record.

The Effect of Walking on Depressive and Anxiety Symptoms: Systematic Review and Meta-Analysis

Background

Previous literature lacks summative information on the mental health benefits achieved from different forms of walking.

Objective

The aim of this study was to assess the effectiveness of different forms of walking in reducing symptoms of depression and anxiety.

Methods

This was a systematic review and meta-analysis of randomized controlled trials (RCTs) assessing the effects of walking on depressive and anxiety symptoms. MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), Embase, PsycINFO, Allied and Complementary Medicine Database (AMED), CINAHL, and Web of Science were searched on April 5, 2022. Two authors independently screened the studies and extracted the data. Random-effects meta-analysis was used to synthesize the data. Results were summarized as standardized mean differences (SMDs) with 95% CIs in forest plots. The risk of bias was assessed by using the Cochrane Risk of Bias tool.

Results

This review included 75 RCTs with 8636 participants; 68 studies reported depressive symptoms, 39 reported anxiety symptoms, and 32 reported both as the outcomes. One study reported the results for adolescents and was not included in the meta-analysis. The pooled results for adults indicated that walking could significantly reduce depressive symptoms (RCTs: n=44; SMD -0.591, 95% CI -0.778 to -0.403; I2=84.8%; τ2=0.3008; P<.001) and anxiety symptoms (RCTs: n=26; SMD -0.446, 95% CI -0.628 to -0.265; I2=81.1%; τ2=0.1530; P<.001) when compared with the inactive controls. Walking could significantly reduce depressive or anxiety symptoms in most subgroups, including different walking frequency, duration, location (indoor or outdoor), and format (group or individual) subgroups (all P values were <.05). Adult participants who were depressed (RCTs: n=5; SMD -1.863, 95% CI -2.764 to -0.962; I2=86.4%; τ2=0.8929) and those who were not depressed (RCTs: n=39; SMD -0.442, 95% CI -0.604 to -0.280; I2=77.5%; τ2=0.1742) could benefit from walking effects on their depressive symptoms, and participants who were depressed could benefit more (P=.002). In addition, there was no significant difference between walking and active controls in reducing depressive symptoms (RCTs: n=17; SMD -0.126, 95% CI -0.343 to 0.092; I2=58%; τ2=0.1058; P=.26) and anxiety symptoms (14 RCTs, SMD -0.053, 95% CI -0.311 to 0.206, I2=67.7%, τ2=0.1421; P=.69).

Conclusions

Various forms of walking can be effective in reducing symptoms of depression and anxiety, and the effects of walking are comparable to active controls. Walking can be adopted as an evidence-based intervention for reducing depression and anxiety. More evidence on the effect of low-intensity walking is needed in the future.

Exercise-based cardiac rehabilitation for adults with heart failure

BACKGROUND

People with heart failure experience substantial disease burden that includes low exercise tolerance, poor health-related quality of life (HRQoL), increased risk of mortality and hospital admission, and high healthcare costs. The previous 2018 Cochrane review reported that exercise-based cardiac rehabilitation (ExCR) compared to no exercise control shows improvement in HRQoL and hospital admission amongst people with heart failure, as well as possible reduction in mortality over the longer term, and that these reductions appear to be consistent across patient and programme characteristics. Limitations noted by the authors of this previous Cochrane review include the following: (1) most trials were undertaken in patients with heart failure with reduced (< 45%) ejection fraction (HFrEF), and women, older people, and those with heart failure with preserved (≥ 45%) ejection fraction (HFpEF) were under-represented; and (2) most trials were undertaken in a hospital or centre-based setting.

OBJECTIVES

To assess the effects of ExCR on mortality, hospital admission, and health-related quality of life of adults with heart failure.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO and Web of Science without language restriction on 13 December 2021. We also checked the bibliographies of included studies, identified relevant systematic reviews, and two clinical trials registers.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that compared ExCR interventions (either exercise only or exercise as part of a comprehensive cardiac rehabilitation) with a follow-up of six months or longer versus a no-exercise control (e.g. usual medical care). The study population comprised adults (≥ 18 years) with heart failure - either HFrEF or HFpEF.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methods. Our primary outcomes were all-cause mortality, mortality due to heart failure, all-cause hospital admissions, heart failure-related hospital admissions, and HRQoL. Secondary outcomes were costs and cost-effectiveness. We used GRADE to assess the certainty of the evidence.

MAIN RESULTS

We included 60 trials (8728 participants) with a median of six months' follow-up. For this latest update, we identified 16 new trials (2945 new participants), in addition to the previously identified 44 trials (5783 existing participants). Although the existing evidence base predominantly includes patients with HFrEF, with New York Heart Association (NYHA) classes II and III receiving centre-based ExCR programmes, a growing body of trials includes patients with HFpEF with ExCR undertaken in a home-based setting. All included trials employed a usual care comparator with a formal no-exercise intervention as well as a wide range of active comparators, such as education, psychological intervention, or medical management. The overall risk of bias in the included trials was low or unclear, and we mostly downgraded the certainty of evidence of outcomes upon GRADE assessment. There was no evidence of a difference in the short term (up to 12 months' follow-up) in the pooled risk of all-cause mortality when comparing ExCR versus usual care (risk ratio (RR) 0.93, 95% confidence interval (CI) 0.71 to 1.21; absolute effects 5.0% versus 5.8%; 34 trials, 36 comparisons, 3941 participants; low-certainty evidence). Only a few trials reported information on whether participants died due to heart failure. Participation in ExCR versus usual care likely reduced the risk of all-cause hospital admissions (RR 0.69, 95% CI 0.56 to 0.86; absolute effects 15.9% versus 23.8%; 23 trials, 24 comparisons, 2283 participants; moderate-certainty evidence) and heart failure-related hospital admissions (RR 0.82, 95% CI 0.49 to 1.35; absolute effects 5.6% versus 6.4%; 10 trials; 10 comparisons, 911 participants; moderate-certainty evidence) in the short term. Participation in ExCR likely improved short-term HRQoL as measured by the Minnesota Living with Heart Failure (MLWHF) questionnaire (lower scores indicate better HRQoL and a difference of 5 points or more indicates clinical importance; mean difference (MD) -7.39 points, 95% CI -10.30 to -4.77; 21 trials, 22 comparisons, 2699 participants; moderate-certainty evidence). When pooling HRQoL data measured by any questionnaire/scale, we found that ExCR may improve HRQoL in the short term, but the evidence is very uncertain (33 trials, 37 comparisons, 4769 participants; standardised mean difference (SMD) -0.52, 95% CI -0.70 to -0.34; very-low certainty evidence). ExCR effects appeared to be consistent across different models of ExCR delivery: centre- versus home-based, exercise dose, exercise only versus comprehensive programmes, and aerobic training alone versus aerobic plus resistance programmes.

AUTHORS' CONCLUSIONS

This updated Cochrane review provides additional randomised evidence (16 trials) to support the conclusions of the previous 2018 version of the review. Compared to no exercise control, whilst there was no evidence of a difference in all-cause mortality in people with heart failure, ExCR participation likely reduces the risk of all-cause hospital admissions and heart failure-related hospital admissions, and may result in important improvements in HRQoL. Importantly, this updated review provides additional evidence supporting the use of alternative modes of ExCR delivery, including home-based and digitally-supported programmes. Future ExCR trials need to focus on the recruitment of traditionally less represented heart failure patient groups including older patients, women, and those with HFpEF.

Salsolinol improves angiotensin II‑induced myocardial fibrosis in vitro via inhibition of LSD1 through regulation of the STAT3/Notch‑1 signaling pathway

The clinical incidence of congestive heart failure (CHF) is very high and it poses a significant threat to the health of patients. The traditional Chinese medicine monomer salsolinol is widely used to treat similar symptoms of CHF. However, there have been no reports on the effect of salsolinol for the management of CHF and its effects on myocardial fibrosis. In the present study, salsolinol was used to treat angiotensin II (AngII)-induced human cardiac fibroblasts (HCFs) and cell proliferation and migration were assessed using a CCK-8, EdU staining assay and wound healing assay. Subsequently, immunofluorescence, western blotting and other techniques were used to detect indicators associated with cell fibrosis and relevant kits were used to detect markers of cellular inflammation and reactive oxygen species (ROS) production. Molecular docking analysis was used to predict the relationship between salsolinol and lysine-specific histone demethylase 1A (LSD1). Subsequently, the expression of LSD1 in the serum of CHF patients was detected by reverse transcription-quantitative PCR. Finally, LSD1 was overexpressed in cells to explore the regulatory mechanism of salsolinol in AngII-induced HFCs. Salsolinol reduced the proliferation and migration. Salsolinol reduced the expression of fibrosis marker proteins α-smooth muscle actin, Collagen I and Collagen III in a concentration-dependent manner, thereby reducing cell fibrosis. In addition, salsolinol reduced the levels of TNF-α and IL-6 in the cell supernatant and ROS production following AngII induction. Salsolinol inhibited LSD1 expression and regulated the STAT3/Notch-1 signaling pathway. Upregulation of LSD1 reversed the effects of salsolinol on AngII-induced HCFs. Salsolinol inhibited LSD1 via regulation of the STAT3/Notch-1 signaling pathway to improve Ang II-induced myocardial fibrosis in vitro.

Developing an Exercise Attitudes and Behavior Intentions Questionnaire for Survivors of Aortic Dissection: An Exploratory Factor Analysis

Purpose

Our study aimed to develop a questionnaire to assess the reliability and validity of exercise attitudes and behavior intentions among survivors of an aortic dissection (AD).

Methods

There were two phases to the study between April 2021 and April 2022. Phase I involved the development of an initial version of the Exercise Attitudes and Behavior Intentions Questionnaire (EABIQ) through literature reviews, qualitative interviews, Delphi expert consultations and a pre-experimental study. During Phase II, the reliability and validity of the questionnaire was assessed in 160 survivors with AD.

Results

A 62-item EABIQ for AD survivors was developed. Eleven common components with eigenvalues larger than 1 were identified by exploratory factor analysis. The scale's variance explained cumulatively rate was 75.216%. The content validity index at the item level for the EABIQ varied from 0.813 to 1.000 and the S-CVI/Ave was 0.934. The correlation coefficients between each scale dimension and the overall scale ranged from 0.405 to 0.785, with all p-values less than 0.05. Cronbach's alpha for the whole scale was 0.929, with Cronbach's alpha for each domain ranging from 0.835 to 0.965. The overall scale split-half reliability coefficient was 0.960, with each domain's split-half reliability coefficient ranging from 0.844 to 0.962.

Conclusions

The AD exercise attitudes and behavior intentions questionnaire has high reliability and validity and is generally consistent with the hypothetical theoretical framework. It can be used as a judgment tool to measure the exercise behavior for AD patients.

Comparison of the levels of depression and anxiety in elderly aortic stenosis patients treated with surgical or transcatheter aortic valve replacement

Objective

Currently, only a few studies have been conducted on the mental status recovery in elderly aortic stenosis (AS) patients after treatment. How transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) differentially impinge on the mental status of elderly AS patients is completely unknown. The present prospective study aims to investigate this question by comparing the post-treatment levels of depression and anxiety, quality of life and frailty.

Methods

A total of 120 elderly patients (age above 70) with symptomatic AS were included, where 78 of them were treated with TAVR and 42 of them were treated with SAVR. Levels of depression and anxiety, quality of life and frailty were assessed by the Chinese version of Hospital Anxiety and Depression Scale (HADS), World Health Organization Quality of Life Instrument-Older Adults Module (WHOQOL-OLD) and clinical frailty scale, respectively. Scores were recorded and compared at admission, 1 month, 4 months and 8 months after treatment.

Results

Before treatment, both patient groups had similar baseline characteristics and all mental parameters. During the follow-up period, patients in the TAVR group demonstrated significant improvement in all assessed mental parameters to certain extent compared to the SAVR group. Specifically, frailty was significantly improved in the TAVR-treated patients at all three follow-up time points. Levels of depression and anxiety were significantly improved 8 months after treatment, although the remaining patient number is limited. Quality of life was only significantly improved 1 month after treatment.

Conclusion

TAVR may provide a better mental recovery outcome in elderly AS patients.

Personalized individual-based exercise prescriptions are effective in treating depressive symptoms of college students during the COVID-19: A randomized controlled trial in China

BACKGROUND

The COVID-19 pandemic has seriously increased depression prevalence among the public, including Chinese college students. However, many exercise cannot be performed as usual under the stay-at-home order. This study was a 12-week three-arm randomized controlled trial using the intention-to-treat principle, aiming to explore and compare the feasibility and effect of individual-based personalized aerobic-exercise and resistance-training prescriptions on depressive symptoms in college students, and conclude with some recommendations for individual-based exercise prescriptions.

METHODS

Eighty-six college students with depressive symptoms were randomized into aerobic-exercise (AE), resistance-training (RT), and wait-list control (WLC) groups. Participants in two experimental groups received 12-week personalized AE and RT prescriptions on their individual situations, respectively. No intervention was implemented on participants in the WLC group. Depressive symptoms and physical activity (PA) were measured by Zung Self-Rating Depression Scale (SDS) and International Physical Activity Questionnaire-Short Form (IPAQ-SF), respectively. All data were collected at the baseline, 4, 8, and 12 weeks, and 4-week post-intervention.

RESULTS

At 12 weeks, 72.09% of depressive participants improved to "normal." Participants exhibited a statistical reduction in SDS in all 3 groups (p < 0.05) at 12 weeks compared to baseline. Follow-up assessments showed no significant increase in SDS at 4-week post-intervention compared to 12 weeks (p > 0.05). The independent t-test revealed significantly lower SDS in AE and RT group than in WLC group (p _AE < 0.001 and p _RT < 0.05) at 4, 8, and 12 weeks, and 4-week post-intervention. Furthermore, the PA of participants (including total PA and intensities) in both experimental groups represented a significant improvement at 4-week post-intervention compared to baseline (p < 0.05), while no differences were observed in the PA of participants in the WLC group (p > 0.05).

CONCLUSION

Personalized exercise prescriptions have good feasibility as they can increase adherence to intervention and reduce serious adverse events. Besides, individual-based personalized aerobic-exercise and resistance-training prescriptions result in a similar effect in relieving depressive symptoms and improving physical activity in college students. The individual-based exercise programs performed in 45- to 60- min with progressive moderate-to-vigorous intensity, 3 times/week for at least 12 weeks, may reduce depressive symptoms in college students during the COVID-19.

The Impact of Depression on Outcomes in Patients With Heart Failure and Reduced Ejection Fraction Treated in the GUIDE-IT Trial

BACKGROUND

It remains unclear why depression is associated with adverse outcomes in patients with heart failure (HF). We examine the relationship between depression and clinical outcomes among patients with HF with reduced ejection fraction managed with guideline-directed medical therapy (GDMT).

METHODS AND RESULTS

Using the GUIDE-IT trial, 894 patients with HF with reduced ejection fraction were stratified according to a history of depression, and Cox proportional hazards regression modeling was used to examine the association with outcomes. There were 140 patients (16%) in the overall cohort who had depression. They tended to be female (29% vs 46%, P < .001) and White (67% vs 53%, P = .002). There were no differences in GDMT rates at baseline or at 90 days; nor were there differences in target doses of these therapies achieved at 90 days (NS, all). amino-terminal pro-B-type natriuretic peptide levels at all time points were similar between the cohorts (P > .05, all). After adjustment, depression was associated with all-cause hospitalizations (hazard ratio, 1.42, 95% confidence interval 1.11-1.81, P < .01), cardiovascular death (hazard ratio, 1.69, 95% confidence interval 1.07-2.68, P = .025), and all-cause mortality (hazard ratio, 1.54, 95% confidence interval 1.03-2.32, P = .039).

CONCLUSIONS

Depression impacts clinical outcomes in HF regardless of GDMT intensity and amino-terminal pro-B-type natriuretic peptide levels. This finding underscores the need for a focus on mental health in parallel to achievement of optimal GDMT in these patients.

Comorbidity of depression and anxiety leads to a poor prognosis following angina pectoris patients: a prospective study

BACKGROUND

Depression and anxiety are two common mood problems among patients with cardiovascular disease (CVD) and are associated with poor cardiac prognoses. The comorbidity of depression and anxiety is considered to be a more severe psychological status than non-comorbid mood disorders. However, little is known about the relationship between depression or anxiety and noncardiac readmission. We conducted a prospective study on the prognostic impact of depression, anxiety, and the comorbidity of the two among angina pectoris (AP) patients.

METHOD

In this prospective study, 443 patients with AP were included in the analysis. Follow-up assessments were performed 1 year, and 2 years after patient discharges. Clinical outcomes of interest included noncardiac readmission, major adverse cardiovascular events (MACEs), and composite events. Depression and anxiety symptom scores derived from the patient health questionnaire-9 (PHQ-9) and generalised anxiety disorder-7 (GAD-7) questionnaire were used to assess mood symptoms at baseline. Participants with symptom scores of ≥10 on both the depression and anxiety questionnaires formed the clinical comorbidity subgroup. We used multivariable Cox proportional hazards models to evaluate the impact of individual mood symptom and comorbidity on clinical outcomes.

RESULTS

Among all the AP patients, 172 (38. 9%) were determined to have depression symptoms, 127 (28.7%) patients had anxiety symptoms and 71 (16.0%) patients suffered from their comorbidity. After controlling covariates, we found that patients who endured clinical depression (hazard ratio [HR] = 2.38, 95% confidence interval [CI] 1.06-5.33, p = 0.035) and anxiety ([HR] 2.85, 95% [CI] 1.10-7.45, p = 0.032) had a high risk of noncardiac readmission. Compared to participants with no mood symptoms, those with clinical comorbidity of depression and anxiety presented a greater risk of noncardiac readmission ([HR] 2.91, 95% [CI] 1.03-8.18, p = 0.043) MACEs ([HR] 2.38, 95% [CI] 1.11-5.10, p = 0.025) and composite event ([HR] 2.52, 95% [CI] 1.35-4.69, p = 0.004).

CONCLUSION

Depression and anxiety were found to have predictive value for noncardiac readmission among patients with AP. Furthermore, prognoses were found to be worse for patients with comorbidity of depression and anxiety than those with single mood symptom. Additional attention needs to be focused on the initial identification and long-term monitoring of mood symptom comorbidity.

Delayed Improvement of Depression and Anxiety after Transcatheter Aortic Valve Implantation (TAVI) in Stages of Extended Extra-Valvular Cardiac Damage

Background: Depression and anxiety are frequently occurring and likely to be linked to the severity of cardiac diseases like aortic stenosis (AS). This seems to be of interest since a staging classification of extra-valvular cardiac damage in AS has been introduced and shown to be of prognostic relevance. Objective: The current study aimed to investigate the frequency of depression and anxiety in association to staging and their dynamics after transcatheter aortic valve implantation (TAVI). Methods: A total number of 224 AS patients undergoing TAVI were classified according to the 2017 staging classification into stage 0 to 4 and further dichotomized into group A (stage 0 to 2) and B (stage 3 and 4). Using the Hospital Anxiety and Depression Scale (HADS-D), patients were assigned to depressive versus non-depressive or anxious versus non-anxious per staging group respectively, and analyzed at baseline, 6 weeks, 6 months and 12 months after TAVI. Results: After dichotomization, 158 patients (70.5%) were assigned to group A and 66 patients (29.5%) to group B. The part showing pathologic values for depression was 25.4% (57/224 patients) in the entire collective, 26.6% (42/158 patients) in group A and 22.7% (15/66 patients) in group B (p = n.s.). The proportion showing pathologic values for anxiety was 26.8% (60/224 patients) in the entire collective and did not differ between group A (24.7%, 39/158 patients) and B (31.8%, 21/66 patients) (p = n.s.). In patients revealing pathologic values for depression or anxiety prior to TAVI, there were significant and stable improvements over time observable already in short-term (6 weeks) follow-up in group A, and likewise, but later, in long-term (6/12 months) follow-up in group B. Conclusions: Although of proven prognostic relevance, higher stages of extra-valvular cardiac damage are not associated with higher rates of pre-existing depression or anxiety. The TAVI procedure resulted in a persisting reduction of depression and anxiety in patients showing pathologic values at baseline. Notably, these improvements are timely delayed in higher stages.

Comparative effectiveness of exercise training program in patients with heart failure: protocol for a systematic review of randomised controlled trials and network meta-analysis

INTRODUCTION

Heart failure (HF) is an end-stage of numerous heart diseases including hypertension, coronary heart disease and arrhythmia, in which the heart is unable to perform its circulatory function with sufficient efficiency due to structural or functional dysfunction (systolic or diastolic alterations). Strategies such as exercise rehabilitation may improve cardiac function, exercise capacity and health-related quality of life and reduce anxiety and depression in patients with HF. However, the relative effectiveness as well as the hierarchy of exercise interventions have not been well established, although various exercise options are available. Therefore, this protocol proposes to conduct a network meta-analysis (NMA) aiming to compare the effectiveness of different types of exercise training in patients with HF.

METHODS AND ANALYSIS

PubMed, Embase and the Cochrane Library will be searched from inception to March 2021 for relevant randomised controlled trials. Other resources, such as Google Scholar and Clinical Trials.gov will also be considered. Studies assessing exercise rehabilitation in patients with HF will be selected. Two independent reviewers will identify eligible trials. The PEDro risk of bias assessment tool will be used to assess the quality of the included studies. Bayesian NMA will be used when possible to determine the comparative effectiveness of the different exercise interventions. The mean ranks and surface will estimate the ranking probabilities for the optimal intervention of various treatments under the cumulative ranking curve. Subgroup, sensitivity and meta-regression will be conducted to explain the included studies' heterogeneity if possible. We will also use the Grading of Recommendations, Assessment, Development, and Evaluation system to assess the strength of evidence.

ETHICS AND DISSEMINATION

This systematic review and NMA will synthesise evidence on the effectiveness of the different exercises in patients with HF. The results will be submitted to a peer-reviewed journal. No ethical approval will be required because the data used for the review will be exclusively extracted from published studies.

Association between the nurse-led program with mental health status, quality of life, and heart failure rehospitalization in chronic heart failure patients

ABSTRACT

The nurse-led program is associated with a short-term improvement of mental health status (MHS) and quality of life (QOL) in patients with chronic heart failure (CHF). Nonetheless, the long-term effect of this program is undetermined. The aims of the current study were to evaluate the 1-year effects of the nurse-led program on MHS, QOL, and heart failure (HF) rehospitalization among patients with CHF.CHF patients in the control group received standard care, and patients in the treatment group received standard care plus telehealth intervention including inquiring patients' medical condition, providing feedbacks, counseling and providing positive and emotional talk with the patients. At the third, sixth, and twelfth month's follow-up, patients were called by registered nurses to assess the Mental Health Inventory-5 (MHI-5) and Kansas City Cardiomyopathy Questionnaire (KCCQ) scores. HF rehospitalization was also assessed.A total of 300 patients were included and 46% (n = 138) of the patients were in the treatment group. There were no significant between-group differences in the MHI-5 and KCCQ scores at baseline. In the control group, the MHI-5 score was gradually decreased with follow-up and the score was significantly lower than that in the treatment group since the third month's follow-up (63.5 ± 10.6 vs 73.6 ± 10.3). Compared with the treatment group, KCCQ score was lower in the control group from the third month's follow-up (64.3 ± 10.6 vs 73.5 ± 12.3) until the end of the twelfth months' follow-up (45.3 ± 11.2 vs 60.8 ± 11.1). During 12 months' follow-up, the proportion of patients who experienced HF rehospitalization was lower in the treatment group (19.6% vs 24.1%). After adjusting for covariates, the utilization of the nurse-led program, and increase of MHI-5 and KCCQ scores were associated with reduced risk of HF rehospitalization.The nurse-led program is beneficial for the improvement of MHS and QOL for CHF patients, which might contribute to the reduction of HF rehospitalization.

Functional status mediates the association of nutritional status with depressive symptoms in patients with heart failure

AIMS

The decline of nutritional status and depressive symptoms are pandemic in heart failure patients and functional status may play a pivotal role between these. This study aimed to determine whether nutritional status is associated with depressive symptoms and whether functional status mediates this relationship in heart failure patients.

DESIGN

This was a secondary analysis of a cross-sectional study.

METHODS

The data were collected from November 2015-April 2016. Heart failure patients (N = 254) being hospitalized were included in this secondary analysis. The Depression Sub-Scale of the Hospital Anxiety and Depression Scale and the Duke Activity Status Index were used to assess patients' depressive symptoms and functional status. The nutritional status of patients was calculated using the Geriatric Nutritional Risk Index.

RESULTS

In this study, the average scores of depressive symptoms, nutritional status and functional status were 4.91 (SD 3.12), 102.38 (SD 6.57) and 20.58 (SD 8.96) respectively. Out of the 254 patients, 46 patients (18.1%) had significant depressive symptoms (the score of Depression Sub-Scale of the Hospital Anxiety and Depression Scale ≥ 8) and 55 (21.7%) suffered from malnutrition (the score of Geriatric Nutritional Risk Index ≤ 98). In the multiple regression analyses, nutritional status was negatively associated with depressive symptoms (β = -0.142, p = .02) and functional status mediated the relationship between nutritional status and depressive symptoms.

CONCLUSIONS

Many patients with heart failure have malnutrition and depressive symptoms. Functional status plays a mediating role in the relationship between nutritional status and depressive symptoms.

IMPACT

To relieve depressive symptoms in patients with heart failure, it is of importance to improve the functional status, especially for those with poor nutritional status.

An evidence-based structured one-year programme to sustain physical activity in patients with heart failure in primary care: A non-randomized longitudinal feasibility study

Aim

The primary objective of this non-randomized feasibility study was to test a 1-year model programme for sustaining/increasing patients' motivation to perform daily physical activity.

Design

Non-randomized longitudinal feasibility study with a one-group repeated measures design.

Methods

The study took place at a primary care centre in mid-Sweden in 2017-2018. The model programme included individual and group-based support, individualized physical activity prescriptions, a wrist-worn activity tracker and an activity diary. The main outcomes were the participants' perceptions of programme feasibility and scores on the Exercise Self-Efficacy Scale.

Results

Seven patients were recruited. Six patients completed the programme that was perceived to imply learning, motivation and support. Compared with baseline, the median score of the Exercise Self-Efficacy Scale improved 3 months after participants completed the programme.

Sleep quality and ventilatory efficiency in elderly heart failure patients: a pilot study on the short-term effect of 4-week low-intensity aerobic exercise

Background Sleep disturbance and ventilator inefficiency are considered two of the most critical complications for general human wellbeing, particularly in elderly heart failure (HF) patients. Studies examining the effect of low-intensity aerobic exercise in the treatment of sleep disturbance and ventilatory inefficiency in this population of patients are limited.Objective The purpose of the current pilot study was to check the effect of low-intensity aerobic exercise on the quality of sleep and ventilatory efficiency in elderly HF patients.Materials and methods Design: pilot study.

INTERVENTION

participants were recruited for a low-intensity exercise program (40 to 50% of maximum heart rate for 30-40 minutes), five sessions weekly for four weeks. Exercise intensity was monitored during the sessions using heart rate.

OUTCOME MEASURE

sleep quality was assessed pre- and post- four weeks of exercise program usingthe Pittsburgh sleep quality index (PSQI) and ventilatory efficiency was assessed using cardiopulmonary exercise test.Results HF patients (II-III NYHA), mean age 69.4±4.2 years, body mass index 23.7±2.7 kg/m2, ejection fraction 32.7±4.5 %, VO2peak 16.27±4.2 ml/kg/min, VE/VCO2 30.81±12.7. The mean of global PSQI score ranged between 8.2 to 11.4 with a mean of 9.7±3.4 which indicates that the participants experienced sleep disturbance. The post-exercise assessment showed that patients have reported a significant improvement of all PSQI domains compared with baseline assessment (p&lt;0.05). VO2peak significantly increased from 16.27±4.2 pre-intervention to 20.03±2.6 ml/kg/min post-intervention (p=0.049) whereas VE/VCO2 slightly decreased with a non-significant difference at the end of the study program (p=0.594) indicating animprovement of ventilator efficiencyand overall cardiorespiratory fitness.Conclusion Short-term application of low-intensity aerobic exercise (4 weeks) may improve the quality of sleep and ventilator efficiency in elderly HF patients. The study findings encourage elderly HF patients with sleep disturbance to adhere to the exercise training program. Also, cardiac rehabilitation programs with low intensity of aerobic exercise should be proposed to these patients by their health care provider.

Benefits of Tai Chi Exercise Among Adults With Chronic Heart Failure: A Systematic Review and Meta-Analysis

BACKGROUND

Exercise-based cardiac rehabilitation is safe and effective for adults with chronic heart failure (CHF), yet services are greatly underutilized. However, tai chi is a popular and safe form of exercise among older adults with chronic health conditions.

OBJECTIVE

A systematic review and meta-analysis was conducted to examine the benefits of tai chi exercise among persons with CHF.

METHODS

An electronic literature search of 10 databases (Allied and Complementary Medicine Database, Cumulative Index to Nursing and Allied Health Literature, Embase, OpenGrey, PsycARTICLES, PsycINFO, PubMed, Scopus, SPORTDiscus, and Web of Science) was conducted from January 1, 2004, to August 1, 2019. Clinical trials that examined tai chi exercise, were published in English or German languages, and conducted among participants with CHF were included. Comprehensive Meta-Analysis version 2.0 software (Biostat, Inc) was used to calculate effect sizes (ie, Hedges g) and 95% confidence intervals using random effects models.

RESULTS

A total of 6 studies met the inclusion criteria, enrolling 229 participants (mean age, 68 years; 28% women; mean ejection fraction = 37%). At least 3 studies reported outcomes for exercise capacity (n = 5 studies), quality of life (n = 5 studies), depression (n = 4 studies), and b-type natriuretic peptide (n = 4 studies), allowing for meta-analysis. Compared with controls, tai chi participants had significantly better exercise capacity (g = 0.353; P = .026, I = 32.72%), improved quality of life (g = 0.617; P = .000, I = 0%), with less depression (g = 0.627; P = .000, I = 0%), and decreased b-type natriuretic peptide expression (g = 0.333; P = .016, I = 0%).

CONCLUSION

Tai chi can be easily integrated into existing cardiac rehabilitation programs. Further research is needed with rigorous study designs and larger samples before widespread recommendations can be made.

Effect of Moderate-Intensity Aerobic Exercise on Hepatic Fat Content and Visceral Lipids in Hepatic Patients with Diabesity: A Single-Blinded Randomised Controlled Trial

OBJECTIVE

Limited studies have assessed the effect of moderate-intensity continuous aerobic exercise on hepatic fat content and visceral lipids in hepatic patients with diabesity. This study was designed to evaluate hepatic fat content and visceral lipids following moderate-intensity continuous aerobic exercise in hepatic patients with diabesity.

DESIGN

A single-blinded randomised controlled trial.

METHODS

Thirty-one diabetic obese patients with nonalcoholic fatty liver disease were recruited into this study. The patients were randomly classified into exercise and control groups, fifteen patients in the exercise group and sixteen patients in the control group. The exercise group received an 8-week moderate-intensity continuous aerobic exercise program with standard medical treatment, while the control group received standard medical treatment without any exercise program. Hepatic fat content and visceral lipids were assessed before and after intervention at the end of the study.

RESULTS

Baseline and clinical characteristics showed a nonsignificant difference between the two groups (p > 0.05). At the end of the intervention, the aerobic exercise showed significant improvements (serum triglycerides and low-density lipoproteins (LDLs), p ≤ 0.002, total cholesterol, p=0.004, visceral fats, p=0.016, glycated hemoglobin (HbA1C), p=0.022, high-density lipoproteins (HDLs), p=0.038, alanine transaminases (AL), p=0.044, intrahepatic triglyceride and HOMA-IR, p=0.046, and body mass index (BMI), p=0.047), while the control group showed a nonsignificant difference (p > 0.05). The postintervention analysis showed significant differences in favor of the aerobic exercise group (p < 0.05).

CONCLUSIONS

Moderate-intensity continuous aerobic exercise reduces the hepatic fat content and visceral lipids in hepatic patients with diabesity. Recommendations should be prescribed for encouraging moderate-intensity aerobic exercise training, particularly hepatic patients with diabesity.

Similar effects of low to moderate-intensity exercise program vs moderate-intensity continuous exercise program on depressive disorder in heart failure patients: A 12-week randomized controlled trial

BACKGROUND

Heart failure related depression is recently increased worldwide. Heart failure (HF) disease is identified as a critical cause of increasing morbidity, hospital readmission, and mortality. The most important purpose of treatment of HF disease is to relief disease problems, improve functional performance, and achieve better quality of life.

OBJECTIVES

This study was proposed to evaluate the effects of low to moderate-intensity exercise program vs moderate-intensity continuous exercise program on the level of depressive disorder in heart failure patients.

STUDY DESIGN

12-week randomized controlled trial.

METHODS

Sixty nine HF patients with mild to moderate level of depression and ejection fraction <40% were examined before and after 12-week intervention. Their age was ranged from 40 to 60 years. Patients were randomly classified into 3 groups. Group I (n = 23) received low to moderate intensity exercise program (LMIEP), group II (n = 23) received moderate-intensity exercise program (MICEP), and group III (n = 23) did not receive any exercise program (Non-exercised group). All patients were instructed to conduct home-based exercise with their pharmacological therapy. The level of depression was evaluated before and after 12 weeks of the intervention program.

RESULTS

The 3 study groups were associated with significant decrease of depression level (P < .05). Significant differences were exhibited between the 3 groups in favor to both exercise programs (P < .05) with non-significant differences between the 2 exercise programs (P > .05).

CONCLUSIONS

Both exercise programs had positive effects in reducing the severity of depression in HF patients. Low to moderate and moderate-intensity exercise programs should be proposed for depression illness specially patients with heart failure.

Examining the impacts of 12 weeks of low to moderate-intensity aerobic exercise on depression status in patients with systolic congestive heart failure - A randomized controlled study

OBJECTIVES

Psychiatric depression disorder is common in patients with systolic congestive heart failure (HF), and both conditions share underlying pathophysiological mechanisms. The incidence rate of depression disorder has clearly increased with the increase in HF manifestations in recent decades. Depression disorder is considered an independent predisposing factor for hospitalization, disturbed functional performance, and high rates of morbidity and mortality in HF patients. This randomized controlled study was designed to examine the impacts of low- to moderate-intensity aerobic exercise training on depression status in patients with systolic congestive HF.

METHODS

A total of 46 systolic congestive HF patients with depression (40-60 years of age) were randomized to receive twelve weeks of mild- to moderate-intensity aerobic exercise plus standard medical treatment (exercise group) or standard medical treatment without any exercise intervention (control group). Depression status was examined using the validated Patient Health Questionnaire-9 (PHQ9) pre- and post-intervention at the end of the study program.

RESULTS

No significant differences were observed between the exercise and control groups in demographic data or clinical characteristics (p>0.05). Both study groups showed a significant reduction in depression status at the end of the 12-week intervention (p<0.05). The comparison between the mean values of the depression scores showed significant differences between the two groups after 6 and 12 weeks of the intervention, indicating a greater reduction in depression scores in the exercise group than in the control group (p<0.05).

CONCLUSIONS

Twelve weeks of a low- to moderate-intensity aerobic exercise program was safe and effective for reducing depression severity in patients with systolic congestive HF. Low- to moderate-intensity aerobic training should be recommended for cardiac patients, particularly those with HF-related depression.
