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

Impact of Different Exercise Modalities on Physical Function and Quality of Life in Patients with Heart Failure

Heart failure, a chronic condition, often manifests with reduced physical function and an overall decline in quality of life. It is considered critical that patients with heart failure recover as soon as possible; exercise training, which includes aerobic exercise, resistance exercise, inspiratory muscle training, traditional mind-body exercise, and combined training, facilitates this. The research progress on the impact of various exercise modalities on the physical function and quality of life of patients with heart failure is systematically reviewed in this article. The objective is to augment the understanding of healthcare personnel regarding the status of implementation and outcomes associated with varied exercise modalities. This endeavor seeks to provide a point of reference for the development of exercise rehabilitation programs tailored to individuals contending with heart failure.

Acceptability and Feasibility of a Tai Chi/Qigong Intervention for Older People Living With HIV

Tai chi/qigong (TCQ) is a low impact, meditative movement with breathwork that may benefit people with HIV (PWH) over 50 years old. This study is a feasibility clinical trial of a remote TCQ intervention for older PWH. Participants (n = 48) were recruited via clinic sites and social media and randomized to a TCQ, sham qigong, or wait-list control group. The 12-week intervention included fourteen 45-60-minute sessions. Acceptability (satisfaction, attitudes, practice, attendance) and feasibility (retention rate, adverse events, remote delivery) data were surveyed. Overall retention rate was 72.9%, but 81.2% for the TCQ group. Most TCQ participants attended at least 10 sessions (62.5%) and were practicing TCQ after 2 weeks (72.7%). Over 92% of TCQ participants reported satisfaction and positive attitudes and preferred remote versus in person delivery (63.6%). Two mild intervention related adverse events occurred. Findings suggest that a remote TCQ intervention is acceptable, feasible, and safe among older PWH.

Effectiveness of Tai Chi in Patients With Hypertension: An Overview of Meta-analyses

BACKGROUND

Hypertension affects more than 1 billion people worldwide. Hypertension management guidelines recommend regular exercise to control blood pressure. Tai Chi is a low-impact, low- to moderate-intensity exercise that has numerous health benefits.

OBJECTIVE

The aim of this study is to perform a review of meta-analyses and summarize the existing information on the health benefits of Tai Chi for patients with hypertension.

METHODS

This review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. Eight health-related databases were systematically searched from their inception to March 2021 to identify the relevant meta-analyses. Two reviewers independently assessed the methodological quality of the evidence.

RESULTS

A total of 6 relevant meta-analyses were included in this review: 3 were rated as critically low in quality, 2 were rated low, and 1 was rated high. In the included meta-analyses, Tai Chi showed many benefits for patients with hypertension. In addition to improving blood pressure, the blood lipid profile, blood sugar, body measurements, and quality of life of patients improved significantly after practicing Tai Chi.

CONCLUSION

Tai Chi may be considered an effective and safe alternative exercise for patients with hypertension.

Effect of Traditional Chinese Exercises on Patients with Chronic Heart Failure (TCE-HF): A Systematic Review and Meta-Analysis

Exercise-based cardiac rehabilitation is safe and effective for chronic heart failure (CHF) patients. The present study aimed to investigate the effects of traditional Chinese exercise (TCE) on patients with CHF and the impact of exercise types and duration. Evaluation of randomized controlled trials (RCTs) of TCE in patients with CHF published since 1997 from PubMed, Embase, Web of Science, the Cochrane Library, Chongqing VIP, Wanfang Databases, and the China National Knowledge was performed. A total of 41 RCTs, including 3209 patients with CHF, were included. It showed that TCE significantly increased 6-min walk distance (6MWD) [mean difference (MD) = 72.82 m, p < 0.001] and left ventricular ejection fraction (MD = 5.09%, p < 0.001), whereas reduced B-type natriuretic peptide (BNP) (MD = −56.80 pg/mL, p < 0.001), N-terminal pro-BNP (MD = −174.94 pg/mL, p < 0.05), and Minnesota Living with Heart Failure Questionnaire scores (MD = −11.31, p < 0.001). However, no significant difference was found in the effects of TCE on peak oxygen consumption. The increase in TCE weekly duration and program duration significantly improved 6MWD (MD = 71.91 m, p < 0.001; MD = 74.11 m, p < 0.001). The combination of TCE and conventional aerobic exercise significantly improved 6MWD (MD = 19.86 m, p < 0.005). TCE improves exercise capacity, cardiac function, and quality of life in patients with CHF, which might be an optimal and available pattern of exercise-based cardiac rehabilitation.

Effects of Baduanjin exercise on quality-of-life and exercise capacity in patients with heart failure: A systematic review and meta-analysis

PURPOSE

Exercise training is an efficient non-pharmacological intervention for patients with heart failure (HF). This study aimed to objectively evaluate the effects of Baduanjin exercise on the quality of life (QOL) and exercise capacity in patients with HF.

METHODS

PubMed, Embase, the Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), and Wanfang data were searched from the date of their inception until 30 September 2022. All randomised controlled trials (RCTs) evaluating the effects of Baduanjin exercise on QOL and exercise capacity in patients with HF were selected. The primary outcomes were QOL, assessed using the Minnesota Living with Heart Failure Questionnaire (MLHFQ), and exercise capacity, evaluated using the 6-min walking test (6-MWT). A meta-analysis was performed by comparing the MLHFQ domain scores. Review Manager 5.3 and Stata 14.0, were used for the data analysis.

RESULTS

Baduanjin exercise showed a favourable improvement of the overall QOL (mean difference = -8.25; 95% confidence interval: -13.62 to -2.89; P = 0.003) and exercise capacity (mean difference = 118.49; 95% confidence interval: 52.57 to 184.41; P = 0.0004). Meta-analyses of the MLHFQ domain score indicated that Baduanjin exercise significantly improved the patients' physical (mean difference = -2.83; 95% confidence interval: -3.76, -1.90; P < 0.00001), emotional (mean difference = -2.52; 95% confidence interval: -3.67 to -1.37; P < 0.0001), and general QOL (mean difference = -2.61; 95% confidence interval: -5.17 to -0.06; P = 0.05), based on the decrease in the MLHFQ domain score. Marked statistical heterogeneity (I2> 70%) was observed for all the QOL and exercise capacity outcomes.

CONCLUSIONS

Baduanjin exercise is a safe, feasible, and acceptable intervention that can improve the QOL and exercise capacity in patients with HF. However, more RCTs with rigorous research designs are needed to assist in the rehabilitation of such patients.

Study protocol for a revised randomized trial: Remotely delivered Tai Chi and wellness for Gulf War illness

BACKGROUND

Many of the 700,000 American military personnel deployed to the Persian Gulf region in 1990 and 1991 have since reported health symptoms of unknown etiology. This cluster of symptoms has been labeled Gulf War Illness and include chronic musculoskeletal pain, fatigue, headaches, memory and attention difficulties, gastrointestinal complaints, skin abnormalities, breathing problems, and mood and sleep problems [1,2]. There have been few high-quality intervention trials and no strong evidence to support available treatments [3]. Tai Chi is an ancient Chinese martial art with benefits that include enhancing physical and mental health and improving quality of life for those with chronic conditions.

PROPOSED METHODS

In this randomized controlled trial, GW Veterans are randomly assigned to either Tai Chi or a Wellness control condition, with both remotely delivered intervention groups meeting twice a week for 12 weeks. The primary aim is to examine if Tai Chi is associated with greater improvements in GWI symptoms in Veterans with GWI compared to a Wellness intervention. Participants will receive assessments at baseline, 12 weeks (post-intervention), and follow-up assessments 3- and 9-months post-intervention. The primary outcome measure is the Brief Pain Inventory that examines pain intensity and pain interference.

CONCLUSION

This trial will produce valuable results that can have a meaningful impact on healthcare practices for GWI. If proven as a helpful treatment for individuals with GWI, it would support the implementation of remotely delivered Tai Chi classes that Veterans can access from their own homes.

Lifestyle Modification in Heart Failure Management: Are We Using Evidence-Based Recommendations in Real World Practice?

The heart failure (HF) guideline's purpose is to assist medical professionals while treating patients with HF in accordance with the best current research. Many cases of HF are both, avoidable and treatable thanks to scientific trials. Management is, therefore, based on lifestyle changes, also called non-pharmacological treatment. These, based on lifestyle changes, should be recommended in every patient at risk for HF or with diagnosed of HF, but evidence in itself is scarce. DASH Diet could be clearly beneficial while Mediterranean diet doesn't have enough evidence at the present moment. Smoking should be stopped, and excessive amounts of alcohol drinking avoided, but there is no clinical trial nor registry performed on these aspects. A moderate salt restriction is better than a strict reduction. Exercise and cardiac rehabilitation are beneficial but there are no clear recommendations about type, duration, etc. Most of the evidence that we have in HF patients with obesity is contradictory. Finally, due to the high number of aged frail patients in HF lifestyle changes should be individualized, but again available data is scant. Therefore, due to the lack of current evidence, these gaps need to be considered and need new efforts on investigation in the next future.

Complementary and Alternative Medicines in the Management of Heart Failure: A Scientific Statement From the American Heart Association

Complementary and alternative medicines (CAM) are commonly used across the world by diverse populations and ethnicities but remain largely unregulated. Although many CAM agents are purported to be efficacious and safe by the public, clinical evidence supporting the use of CAM in heart failure remains limited and controversial. Furthermore, health care professionals rarely inquire or document use of CAM as part of the medical record, and patients infrequently disclose their use without further prompting. The goal of this scientific statement is to summarize published efficacy and safety data for CAM and adjunctive interventional wellness approaches in heart failure. Furthermore, other important considerations such as adverse effects and drug interactions that could influence the safety of patients with heart failure are reviewed and discussed.

Effectiveness of Tai Chi on older adults: A systematic review of systematic reviews with re-meta-analysis

This overview study examined and synthesized the effect of Tai Chi (TC) on the physical conditions, psychological conditions, cognitive abilities, and quality of life (QoL) of older adults. This study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement. Using Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register, PubMed, Scopus, and Web of Science, English-language systematic reviews (SRs) published within the latest decade (2010-2020) were included. SRs with meta-analysis were selected if TC was the examined intervention and older adults was the targeted population. A total of 16 SRs covering 89 original studies were included. A number of the pooled results of the included SRs were inconclusive. Taking into consideration of the new meta-analyses of this study, TC significantly improved most outcomes, including the mobility, pain level, physical function, psychological distress, depressive symptoms, anxiety, global cognitive function, mental speed and attention, learning ability, verbal fluency, executive function, and QoL of older adults. TC can be an effective intervention for older adults for improving physical and psychological conditions, cognitive abilities, and QoL. Additional high-quality studies with larger samples investigating the effectiveness of TC in older adults are warranted.

Effects of Tai Chi on health status in adults with chronic heart failure: A systematic review and meta-analysis

Background

Chronic heart failure (CHF) is among the top causes of cardiovascular morbidity, and most patients with CHF have poor health status. Tai Chi, a mind-body exercise that originated in China, is beneficial for health status. This study was conducted to evaluate the effects of Tai Chi on health status in adults with CHF.

Methods

The Cochrane Library, PubMed, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang Database, Chinese Biomedical Database, and Chinese Scientific Journal Database were searched from the inception to 22 October 2021. This meta-analysis was performed using the fixed- or random-effects model. Continuous outcomes were carried out using mean difference (MD) or standardized mean difference (SMD) with 95% confidence interval (CI). Dichotomous outcomes were determined using risk ratio (RR) with 95%CI. The Grading of Recommendations, Assessment, Development and Evaluations (GRADE)pro Guideline Development Tool (GDT) online software was used to present outcome-specific information regarding overall certainty of evidence from studies.

Results

In total, 15 studies including 1,236 participants were finally included. Compared with usual care alone, Tai Chi combined with usual care achieved efficacy in improving Minnesota Living with Heart Failure Questionnaire (MD = -8.51; 95% CI: -10.32 to -6.70; p < 0.00001), 6-min walk test (MD = 43.47; 95% CI: 33.38 to 54.10; p < 0.00001), left ventricular ejection fraction (MD = 6.07; 95% CI: 3.44 to 8.70; p < 0.00001), B-type natriuretic peptide/N-terminal fragment of pro-BNP (SMD = -1.12; 95% CI: -1.70 to -0.54; p = 0.0002), Hamilton Depression Rating Scale (MD = -2.89; 95% CI: -4.87 to -0.91; p = 0.004), Pittsburgh Sleep Quality Index (MD = -2.25; 95% CI: -3.88 to -0.61; p = 0.007), timed up and go test (MD = -1.34; 95% CI: -2.50 to -0.19; p = 0.02), and reduced the risk of heart failure hospitalization (RR = 0.47; 95% CI: 0.25 to 0.88; p = 0.02). However, there was no difference in the outcome of peak oxygen uptake (MD = 1.38; 95% CI: -1.51 to 4.28; p = 0.35). All-cause mortality or cardiovascular death could not be evaluated due to insufficient data. The certainty of evidence ranged from very low to moderate due to the risk of bias, inconsistency, imprecision, and publication bias.

Conclusion

Tai Chi might be safe and showed beneficial effects on health status in patients with CHF. However, more high-quality and long-term studies are still needed to further evaluate the effects of Tai Chi.

Tai Chi and Qigong for trauma exposed populations: A systematic review

Background

Trauma exposure and posttraumatic stress are highly prevalent and comorbid with health problems. Despite the apparent systemic nature of post-traumatic stress, recommended treatments neglect trauma's deleterious effects on health. Integrative mind-body treatments for posttraumatic stress, such as Tai Chi and Qigong (TCQ), may offer a promising adjunct to first-line treatments.

Method

A systematic search was conducted to identify trials that examined Tai Chi and/or Qigong as treatments for trauma-exposed populations. Studies were examined for rigor; design, sample and intervention characteristics, dropout, attendance, satisfaction, acceptability, and key findings were systematically extracted.

Results

The 6 studies included are all pilot or feasibility trials with descriptive or mixed-methods outcomes. No randomized trials or rigorous studies were identified. Dropout rates ranged widely, and adverse reactions were not evident. Reported satisfaction was high and benefits of relaxation, reductions in mental health symptoms, and improvements in pain and physical and cognitive functioning were noted.

Limitations

All the studies were non-rigorous and relatively small, with no comparison groups, or follow-up assessments; in many cases, posttraumatic stress symptoms were not formally assessed.

Conclusions

The paucity and lack of rigor of the studies identified for this review highlights the need for larger, methodologically sound clinical trials. The reviewed studies suggest that TCQ practices have the potential to reduce symptoms and improve functioning for individuals exposed to trauma and provide evidence that TCQ is feasible, acceptable, and low risk in these populations. Possible mechanistic pathways supporting TCQ as a treatment for posttraumatic stress are considered.

Tai Chi for anxiety and depression symptoms in cancer, stroke, heart failure, and chronic obstructive pulmonary disease: A systematic review and meta-analysis

BACKGROUND

Many middle-aged and older adults have more than one chronic health condition. It is therefore important to explore the effectiveness of interventions for multiple chronic conditions. Tai Chi is widely used in China and other countries, and many studies have examined the effect of Tai Chi on anxiety and depression. However, there are no systematic reviews of the effect of Tai Chi on anxiety and depression in various chronic conditions. This systematic review and meta-analysis aimed to evaluate the effects of Tai Chi on anxiety and depression symptoms in four chronic conditions: cancer, stroke, heart failure (HF), and chronic obstructive pulmonary disease (COPD).

METHODS

We searched Chinese and English databases (Cochrane Library, PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), Wanfang Database, and Sinomed) from inception to October 2020. Review Manager version 5.2 and Stata version 12.0 were used to perform a systematic review. The quality of the included studies was evaluated using the Cochrane risk of bias tool. The study was registered with the PROSPERO database (number CRD42020209594).

RESULTS

Of the 596 studies identified, we included 25 randomized controlled trials involving 1819 participants. Combined analysis of the four diseases showed statistically significant differences between the Tai Chi and control groups for anxiety symptoms (SMD -0.99, 95%CI: -1.5, -0.47; P < 0.01) and depressive symptoms (SMD 0.70, 95%CI: -1.01, -0.39; P < 0.01). Subgroup analyses showed statistically significant differences between the Tai Chi and control groups for depressive symptoms in stroke (SMD -0.43, 95%CI: -0.67, -0.18; P < 0.01) and HF (SMD -0.57, 95%CI: -0.8, -0.33; P < 0.01). However, no statistically significant differences were found for depressive symptoms in COPD or cancer. There were statistically significant differences between the Tai Chi and control groups for anxiety symptoms in stroke (SMD -0.60, 95%CI: -0.88, -0.32; P < 0.01) and cancer (SMD -0.69, 95%CI: -1.22, -0.17; P < 0.01), but not in COPD or HF. Subgroup, sensitivity, meta regression, and publication bias analyses showed high heterogeneity correlated with a single study and study quality. Sensitivity analysis showed that most meta-analysis results had good stability, but those for anxiety symptoms in COPD were unstable; therefore, careful interpretation is required.

CONCLUSION

Tai Chi has a positive effect on anxiety and depression, especially for patients with cancer, stroke, and HF. However, given the weak evidence, this approach is not a substitute for psychiatric treatment.

Effect of traditional Asian exercise on patients with chronic heart failure: a protocol for network meta-analysis of randomised controlled trials

INTRODUCTION

Chronic heart failure (CHF) is a common disease worldwide, and imposes a substantial burden to the healthcare system. In CHF, limited exercise capacity and affected mental well-being leads to a reduced quality of life (QOL). How to improve the QOL and exercise endurance is critical for patients with CHF. Exercise therapy, such as some traditional Asian exercises (TAEs) including Taichi, Baduanjin and Yoga, plays an important role in the rehabilitation of patients with CHF. TAE is suitable for the rehabilitation of patients with CHF because of its soft movements and can relax the body and mind. Studies have shown that TAE can regulate the overall health status of the body and exercise tolerance, improve QOL and reduce rehospitalisation rate in patients with CHF. However, the difference in efficacy of TAE in patients with CHF is not yet clear. The main purpose of this study is to conduct a network meta-analysis (NMA) of randomised trials to determine the impact of TAE on patients with CHF of different types, different causes and different New York Heart Association (NYHA) heart function classifications and to provide references for different types of patients with CHF to choose appropriate exercise rehabilitation therapy.

METHODS AND ANALYSIS

The literature search will be retrieved from PubMed, the Cochrane Library, Embase, Web of Science, Chinese National Knowledge Infrastructure, Wanfang database, Chinese biomedical literature service system (SinoMed) and Chinese Scientific Journals Database (VIP) from the date of their inception until 1 August 2021. All randomised controlled trials that evaluated the effects of three different TAE therapies (Taichi, Baduanjin and Yoga) on patients with CHF will be included. The primary outcomes are peak oxygen uptake (peak VO₂), exercise capacity (6-min walking distance) and QOL tested with the Minnesota Living with Heart Failure Questionnaire. Secondary outcomes include the levels of N-terminal pro brain natriuretic peptide, left ventricular ejection fraction, systolic blood pressure and diastolic blood pressure. For included articles, two reviewers will independently extract the data, and Cochrane Collaboration's tool will be used to assess risk of bias. We will perform the Bayesian NMA to pool all treatment effects. The ranking probabilities for the optimal intervention of various treatments (Taichi, Baduanjin or Yoga) will be estimated by the mean ranks and surface under the cumulative ranking curve. Subgroup analysis for different types, different causes and different NYHA heart function classifications of CHF will be performed. We will use the Grading of Recommendations Assessment, Development and Evaluation system to assess the quality of evidence contributing to each network estimate.

ETHICS AND DISSEMINATION

The results will be disseminated through peer-reviewed publications. They will provide useful information to inform clinicians on the potential functions of TAE in CHF, and to provide consolidated evidence for clinical practice and further research of TAE.

The Effects of Tai Chi Exercise Among Adults With Chronic Heart Failure: An Overview of Systematic Review and Meta-Analysis

Background: Tai chi (TC) is a popular form of exercise among adults with chronic heart failure (CHF), yet services are greatly underutilized. The aim of the current study was to identify and summarize the existing evidence and to systematically determine the clinical effectiveness of Tai Chi in the management of CHF using a systematic overview.

Methods: Both English and Chinese databases were searched for systematic reviews (SRs)/meta-analyses (MAs) on TC for CHF from their inception to June 2020. The methodological quality, reporting quality, and risk of bias of SRs/MAs were assessed using Assessing the Methodological Quality of Systematic Reviews 2 (AMSTAR-2), the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist, and Risk of Bias in Systematic reviews (ROBIS), respectively. The evidence quality of outcome measures was assessed by the Grades of Recommendations, Assessment, Development and Evaluation (GRADE).

Results: Six SRs/MAs using a quantitative synthesis to assess various outcomes of TC in CHF were included in this overview. The methodological quality, reporting quality and risk of bias of the SRs/MAs and the evidence quality of the outcome measures are generally unsatisfactory. The limitations of the past SRs/MAs included the lack of either the protocol or registration, the list of excluded studies, and the computational details of meta-analysis were inadequately reported. The critical problems were that qualitative data synthesis relied on trials with small sample sizes and critical low quality.

Conclusions: TC may be a promising complementary treatment for CHF. However, further rigorous and comprehensive SRs/MAs and RCTs are required to provide robust evidence for definitive conclusions.
