Efficacy of Different Types of Exercise-Based Cardiac Rehabilitation on Coronary Heart Disease: a Network Meta-analysis.

ABSTRACT: BACKGROUND:Exercise-based cardiac rehabilitation (CR) has been recognized as an essential component of the treatment for coronary heart disease (CHD). Determining the efficacy of modern alternative treatment methods is the key to developing exercise-based CR programs. METHODS:Studies published through June 6, 2016, were identified using MEDLINE, EMBASE, and the Cochrane Library. English-language articles regarding the efficacy of different modes of CR in patients with CHD were included in this analysis. Two investigators independently reviewed abstracts and full-text articles and extracted data from the studies. According to the categories described by prior Cochrane reviews, exercise-based CR was classified into center-based CR, home-based CR, tele-based CR, and combined CR for this analysis. Outcomes included all-cause mortality, cardiovascular death, recurrent fatal and/or nonfatal myocardial infarction, recurrent cardiac artery bypass grafting, recurrent percutaneous coronary intervention (PCI), and hospital readmissions. RESULTS:Sixty randomized clinical trials (n?=?19,411) were included in the analysis. Network meta-analysis (NMA) demonstrated that only center-based CR significantly reduced all-cause mortality (center-based: RR?=?0.76 [95% CI 0.64-0.90], p?=?0.002) compared to usual care. Other modes of CR were not significantly different from usual care with regard to their ability to reduce mortality. Treatment ranking indicated that combined CR exhibited the highest probability (86.9%) of being the most effective mode, but this finding was not statistically significant due to the small sample size (combined: RR?=?0.50 [95% CI 0.20-1.27], p?=?0.146). CONCLUSIONS:Current evidence suggests that center-based CR is acceptable for patients with CHD. As home- and tele-based CR can save time, money, effort, and resources and may be preferred by patients, their efficacy should be investigated further in subsequent studies.

Project description:Background: Many heart failure (HF) patients admitted to cardiac rehabilitation (CR) centers have a cardiac resynchronization therapy (CRT) device. However, information about the efficacy and safety of exercise rehabilitation in HF patients with a CRT device is scant. We assessed the effects of exercise rehabilitation in HF patients with a CRT device. Methods and Results: The PubMed, EMBASE, Cochrane Central Register of Controlled Trials, CINAHL, PsycInfo, China Biology Medicine, Wanfang, and China National Knowledge Infrastructure databases were searched comprehensively to identify randomized controlled trials (RCTs) published between January 1, 1990 and July 1, 2019 on exercise rehabilitation in HF patients with CRT devices. We identified seven studies published from 2006 to 2019, including 661 patients with an intervention duration of 8 to 24 weeks. Three studies reported all-cause mortality and serious adverse events, and no significant difference was found between exercise rehabilitation patients and controls at the longest available follow-up (both P > 0.05; both I 2 = 0%). Exercise rehabilitation patients exhibited a higher exercise capacity (peak oxygen uptake: random-effect WMD = 2.02 ml/kg/min, 95% CI 0.62 to 3.41, P = 0.005, I 2 = 67.4%; exercise duration: fixed-effect WMD = 102.34s, 95% CI 67.06 to 137.62, P < 0.001, I 2 = 25%) after intervention, despite the significant heterogeneity of studies. Left ventricular ejection fraction (LVEF) was significantly improved in exercise rehabilitation patients compared to that in controls (fixed-effect WMD = 3.89%, 95% CI 1.50 to 6.28; P = 0.001; I 2 = 48.0%). Due to differences in health-related quality of life (HRQOL) assessment methods, we only pooled data that reported Minnesota Living with Heart Failure Questionnaire scores. Exercise rehabilitation patients exhibited a better HRQOL than controls (fixed-effect WMD = -5.34, 95% CI -10.12 to -0.56; P = 0.028; I 2 = 0%). Conclusions: Exercise rehabilitation may restore exercise capacity and cardiac function in HF patients with a CRT device. Furthermore, exercise training was associated with better HRQOL on follow-up.

Project description:IntroductionCoronary heart disease (CHD) is the most common cause of death worldwide. Percutaneous coronary intervention (PCI) has been shown to reduce mortality in patients with CHD. However, there are still recurrences of cardiovascular events after PCI. Cardiac rehabilitation (CR) in patients with established CHD is associated with reductions in cardiovascular mortality and hospital admissions, as well as improved quality of life. More and more clinical trials suggest that traditional Chinese exercise (TCE) plays a positive role in patients post-PCI. The primary purposes of the current study are to conduct a network meta-analysis of randomised trials to determine the effects of TCE in patients after PCI, and to separately compare the effects of tai chi, baduanjin and yijinjing on CR after PCI.Methods and analysisStudies will be retrieved from the following databases: PubMed, Embase, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang Data, Chinese BioMedical Database and Chinese Science and Technology Periodicals Database, from inception to December 2018. We will include randomised controlled trials that are related to the effects of TCE therapies in patients after PCI. The primary outcomes will be all-cause mortality, revascularisations, health-related quality of life and hospitalisations. Two reviewers will independently select eligible articles. For each included article, two reviewers will independently extract the data and assess the risk of bias by using the Cochrane risk of bias tool. Bayesian network meta-analyses will be conducted to pool all treatment effects. The ranking probabilities for the optimal intervention of various treatments (tai chi, baduanjin or yijinjing) will be estimated by the mean ranks and surface under the cumulative ranking curve. The Grading of Recommendations Assessment, Development and Evaluation System will be used to assess the quality of evidence.Ethics and disseminationThe results will be disseminated through peer-reviewed publications. They will provide consolidated evidence to inform clinicians on the potential functions of TCE in CR, and to provide reliable evidence for the application of TCE.Trial registration numberCRD42018088415.

Project description:BackgroundHeart Transplant (HTx) is the ultimate chance of life for end stage Heart Failure (HF). Exercise training has consistently shown the potential to improve functional capacity in various chronic heart diseases. Still, the evidence in HTx recipients is scarcer. This study aims to systematically review the literature to evaluate the effectiveness and safety of Exercise-based Cardiac Rehabilitation (EBCR) in HTx recipients and to identify possible moderators of success.MethodsWe conducted a systematic review and meta-analysis of randomized controlled trials on the effect and safety of EBCR in adult HTx recipients. The primary outcome was functional capacity, measured by Peak Oxygen Uptake (pVO2). We searched CENTRAL, MEDLINE, Embase, Scopus, and Web of Knowledge databases until December 2020, reviewed references of relevant articles and contacted experts. Usual care (UC), the different dosages of exercise regimens and alternative settings were allowed as comparators. A quantitative synthesis of evidence was performed using random-effects meta-analyses.ResultsA total of 11 studies with 404 patients were included. Nine studies comprising 306 patients compared EBCR with usual care. They showed that EBCR improved pVO2 compared to usual care (Mean Difference [MD] 3.03 mL/kg/min, 95% CI [2.28-3.77]; I 2 = 32%). In the subgroup analysis, including length of intervention and timing of enrollment after HTx, no significant moderator was found. Two trials, with 98 patients total, compared High Intensity Interval Training (HIIT) and Moderate Intensity Continuous Training (MICT). HIIT attained a significant edge over MICT (MD 2.23 mL/kg/min, 95% CI [1.79-2.67]; I 2 = 0%). No major adverse events associated with EBCR were reported.ConclusionWe found moderate quality evidence suggesting EBCR has a significant benefit on functional capacity improvement HTx recipients at the short-term. HIIT showed superiority when compared to MICT. Research focusing long term outcomes and standardized protocols are needed to improve evidence on EBCR effectiveness.
