Project description: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:Cardiovascular disease is the leading cause of morbidity and mortality in the world, including China. Cardiac rehabilitation (CR) has been demonstrated to be beneficial in reducing cardiovascular mortality, myocardial infarction, and cerebrovascular events. This pilot study seeks to assess the feasibility of aerobic-exercise-based CR in Chinese patients with coronary heart disease (CHD) and outcomes of aerobic metabolism capacity and molecular biomarkers. METHODS/DESIGN:This study is a single-center, pilot, randomized, controlled study that is currently being carried out at a regional hospital in Shanghai. Forty patients with CHD who underwent percutaneous coronary intervention will be randomly allocated into either the intervention group or control group. Participants in the intervention group will undergo 8 weeks of aerobic exercise with targeted intensity and participants in the control group will undergo 8 weeks of leisure exercise. The primary measurement is the feasibility of the trial; the secondary measurement is the capacity of aerobic metabolism and the exploratory measurement includes additional molecular biomarkers underlying cardiovascular function. DISCUSSION:This is the first prospective randomized and controlled clinical study in China that assesses the parameters of aerobic metabolism and comprehensively screens for substantial blood biomarkers to reveal the molecular mechanisms underlying changes in cardiovascular function after aerobic exercise with targeted intensity in participants with CHD. The success of this study will contribute to guide the design of future CR studies in patients with CHD in China. TRIAL REGISTRATION:Chinese Clinical Trial Registry, ChiCTR-IPR-17010556 .

Project description:IntroductionThe benefits of cardiac rehabilitation (CR) on the reduction of cardiac and all-cause mortality are well documented. However, adherence remains suboptimal in China. It is clear that traditional CR does not meet the needs of many eligible patients and innovation is required to improve its application. Home-based CR (HBCR) is a cost-effective method that may be a valuable alternative for many individuals in China. In HBCR, it is often difficult to maintain an exercise intensity that is both effective and within safe limits, factors that are essential for patient safety. Mobile health interventions have the potential to overcome these obstacles and may be efficacious in improving adherence. The purpose of this study is to evaluate whether an Intelligent Exercise Rehabilitation Management System (IERMS)-based HBCR could improve adherence to CR and to assess the effects on exercise capacity, mental health, self-efficacy, quality of life and lifestyle-related risk factors.Methods and analysisWe propose a single-blinded, two-arm, randomised controlled crossover study of 70 patients with coronary heart disease (CHD). Participants will be randomly assigned in a 1:1 ratio to one of the two groups. Patients in group 1 will receive the IERMS intervention together with usual care for the first 6?weeks and usual care for the last 6?weeks, while patients assigned to group 2 will receive usual care for the first 6?weeks and will use IERMS in the last 6?weeks. The primary outcome is adherence to the programme and secondary outcomes include exercise capacity, psychological well-being, quality of life, self-efficacy and lifestyle-related risk factors. All secondary outcomes will be measured at baseline, 6?weeks and 12 weeks.Ethics and disseminationThis study has been approved by the Human Research Ethics Committee of the School of Nursing, Jilin University (HREC 2019120901). The results will be published in peer-reviewed journals and at conferences.Trial registration numberChiCTR1900028182; Pre-results.

Project description:To compare home-based cardiac rehabilitation (CR) with usual care (control group with no rehabilitation) in elderly patients who declined participation in centre-based CR.Randomised clinical trial with 12 months follow-up and mortality data after 5.5 years (mean follow-up 4½ years).Rehabilitation unit, Department of Cardiology, Copenhagen, Denmark.Elderly patients ?65 years with coronary heart disease.A physiotherapist made home visits in order to develop an individualised exercise programme that could be performed at home and surrounding outdoor area. Risk factor intervention, medical adjustment, physical and psychological assessments were offered at baseline and after 3, 6 and 12 months.The primary outcome was 6 min walk test (6MWT). Secondary outcomes were blood pressure, body composition, cholesterol profile, cessation of smoking, health-related quality of life (HRQoL), anxiety and depression.40 patients participated. The study population was characterised by high age (median age 77 years, range 65-92 years) and high level of comorbidity. Patients receiving home-based CR had a significant increase in the primary outcome 6MWT of 33.5 m (95% CI: 6.2 to 60.8, p=0.02) at 3 months, whereas the usual care group did not significantly improve, but with no significant differences between the groups. At 12 months follow-up, there was a decline in 6MWT in both groups; -55.2 m (95% CI: 18.7 to 91.7, p<0.01) in the home group and -52.1 m (95% CI: -3.0 to 107.1, p=0.06) in the usual care group. There were no significant differences in blood pressure, body composition, cholesterol profile, cessation of smoking or HRQoL after 3, 6 and 12 months follow-up.Participation in home-based CR improved exercise capacity among elderly patients with coronary heart disease, but there was no significant difference between the home intervention and the control group. In addition, no significant difference was found in the secondary outcomes. When intervention ceased, the initial increase in exercise capacity was rapidly lost.

Project description:Cardiac rehabilitation (CR) is underutilised across the world and India. The use of simple algorithms is one way to facilitate CR, however, these algorithms need to be feasible to use across low resource settings. The objectives were to assess the feasibility of a CR algorithm following percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). A single group, pre-post study on 50 participants undergoing PCI for ACS found significant improvement in various feasibility metrics at discharge and 30-days, with no major adverse events. The proposed CR algorithm was safe and feasible for low and moderate risk patients with ACS undergoing PCI.

Project description:AimsThe onset of the COVID-19 pandemic saw the suspension of centre-based cardiac rehabilitation (CBCR) and has underscored the need for home-based cardiac telerehabilitation (HBCTR) as a feasible alternative rehabilitation delivery model. Yet, the effectiveness of HBCTR as an alternative to Phase 2 CBCR is unknown. We aimed to conduct a meta-analysis to quantitatively appraise the effectiveness of HBCTR.Methods and resultsPubMed, EMBASE, CENTRAL, CINAHL, Scopus, and PsycINFO were searched from inception to January 2021. We included randomized controlled trials (RCTs) comparing HBCTR to Phase 2 CBCR or usual care in patients with coronary heart disease (CHD). Out of 1588 studies, 14 RCTs involving 2869 CHD patients were included in this review. When compared with usual care, participation in HBCTR showed significant improvement in functional capacity {6-min walking test distance [mean difference (MD) 25.58 m, 95% confidence interval (CI) 14.74-36.42]}; daily step count (MD 1.05 K, 95% CI 0.36-1.75) and exercise habits [odds ratio (OR) 2.28, 95% CI 1.30-4.00)]; depression scores (standardized MD -0.16, 95% CI -0.32 to 0.01) and quality of life [Short-Form mental component summary (MD 2.63, 95% CI 0.06-5.20) and physical component summary (MD 1.99, 95% CI 0.83-3.16)]. Effects on medication adherence were synthesized narratively. HBCTR and CBCR were comparably effective.ConclusionIn patients with CHD, HBCTR was associated with an increase in functional capacity, physical activity (PA) behaviour, and depression when compared with UC. When HBCTR was compared to CBCR, an equivalent effect on functional capacity, PA behaviour, QoL, medication adherence, smoking behaviour, physiological risk factors, depression, and cardiac-related hospitalization was observed.

Project description:The heart rate (HR) rises with increased power output, whereby in most healthy individuals, the slope of HR levels off with higher intensity. This corresponds to a downward deflection of the heart rate performance curve (HRPC). Conversely, in patients after myocardial infarction, an upward HRPC deflection is frequently observed that is especially pronounced in patients with compromised left ventricular ejection fraction. To investigate whether regular endurance training during cardiac rehabilitation might normalize HRPC, data of 128 male patients were analyzed. All patients performed three exercise tests: at baseline, after 6 weeks, and after 1 year. Ninety-six patients exercised regularly according to guidelines for 1 year (training group, TG), and 32 stopped after 6 weeks (control group, CG). Similarly, upward-deflected HRPCs were observed at baseline and after 6 weeks in both groups. After 1 year, TG patients had less upward-deflected HRPCs compared with CG ones, corresponding to a partial normalization. Greater changes in HRPC deflection were associated with larger improvements in cardiorespiratory fitness. Our results might indicate improved myocardial function due to long-term rehabilitation. Further, HRPC alterations over time should be considered when prescribing exercise intensities using a target HR, as deflection flattening might render the intensity of corresponding exercise insufficient.

Project description:OBJECTIVES:To determine the effect of contemporary exercise-based cardiac rehabilitation on generic and disease-specific health related quality of life for people with coronary artery disease. DESIGN:Systematic review and meta-analysis. STUDY ELIGIBILITY CRITERIA:Randomised controlled trials testing exercise-based cardiac rehabilitation versus no exercise control that recruited after 31 December 1999. On 30 July 2019, we searched the Cochrane Central Register of Controlled Trials, MEDLINE (Ovid), Embase (Ovid) and CINAHL (EBSCO) databases. STUDY APPRAISAL AND SYNTHESIS:Studies were screened for inclusion by two independent reviewers. Risk of bias was assessed using the Cochrane risk of bias tool. Data were reported as pooled means (95% CI for between-group difference. RESULTS:We identified 24 studies (n=4890). We performed meta-analyses for 15 short-term and 9 medium-term outcomes (36-Item Short Form Survey Instrument (SF-36), EuroQol-5D (EQ-5D) and MacNew, a cardiac-specific outcome). Six short-term and five medium-term SF-36 domains statistically favoured exercise-based cardiac rehabilitation. Only for two short-term SF-36 outcomes, 'physical function' (mean difference 12.0, 95% CI 4.4 to 19.6) and 'role physical' (mean difference 16.9, 95% CI 2.4 to 31.3), did the benefit appear to be clinically important. Meta-analyses of the short-term SF-36 physical and mental component scores, EQ-5D and MacNew and the medium-term SF-36 physical component score, did not show statistically significant benefits. Only two studies had a low risk of bias (n=463 participants). CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS:There is some evidence of a short-term benefit of contemporary exercise-based cardiac rehabilitation on quality of life for people with coronary artery disease. However, the contemporary data presented in this review are insufficient to support its routine use.
