Comprehensive and personalized approach is a critical area for developing remote cardiac rehabilitation programs.

In the evolving landscape of cardiac rehabilitation (CR), adopting digital technologies, including synchronous/real-time digital interventions and smart applications, has emerged as a transformative approach. These technologies offer real-time health data access, continuous vital sign monitoring, and personalized educational enhanced patient self-management and engagement. Despite their potential benefits, challenges and limitations exist, necessitating careful consideration. Synchronous/real-time digital CR involves remote, two-way audiovisual communication, addressing issues of accessibility and promoting home-based interventions. Smart applications extend beyond traditional healthcare, providing real-time health data and fostering patient empowerment. Wearable devices and mobile apps enable continuous monitoring, tracking of rehabilitation outcomes, and facilitate lifestyle modifications crucial for cardiac health maintenance. As digital CR progresses, ensuring patient access, equitable implementation, and addressing the digital divide becomes paramount. Artificial intelligence holds promise in the early detection of cardiac events and tailoring patient-specific CR programs. However, challenges such as digital literacy, data privacy, and security must be addressed to ensure inclusive implementation. Moreover, the shift toward digital CR raises concerns about cost, safety, and potential depersonalization of therapeutic relationships. A transformative shift towards technologically enabled CR necessitates further research, focusing not only on technological advancements but also on customization to meet diverse patient needs. Overcoming challenges related to cost, safety, data security, and potential depersonalization is crucial for the widespread adoption of digital CR. Future studies should explore integrating moral values into digital therapeutic relationships and ensure that digital CR is accessible, equitable, and seamlessly integrated into routine cardiac care. Theoretical frameworks that accommodate the dynamic quality of real-time monitoring and feedback feature of digital CR interventions should be considered to guide intervention development.

Safety and long-term outcomes of remote cardiac rehabilitation in coronary heart disease patients: A systematic review.

Objective: To systematically review the safety and the long-term mortality and morbidity risk-rates of the remotely-delivered cardiac rehabilitation (RDCR) interventions in coronary heart disease (CHD) patients. Methods: The protocol was registered in the International Prospective Register of Systematic Reviews (CRD42023455471). Five databases (Pubmed, Scopus, Cochrane Central Register of Controlled Trials in the Cochrane Library, Cinahl and Web of Science) were reviewed from January 2012 up to August 2023. Inclusion criteria were: (a) randomized controlled trials, (b) RDCR implementation of at least 12 weeks duration, (c) assessment of safety, rates of serious adverse events (SAEs) and re-hospitalization incidences at endpoints more than 6 months. Three reviewers independently performed data extraction and assessed the risk of bias using the Cochrane Risk of Bias tool. Results: 14 studies were identified involving 2012 participants and a range of RDCR duration between 3 months to 1 year. The incidence rate of exercise-related SAEs was estimated at 1 per 53,770 patient-hours of RDCR exercise. A non-statistically significant reduction in the re-hospitalization rates and the days lost due to hospitalization was noticed in the RDCR groups. There were no exercise-related deaths. The overall study quality was of low risk. Conclusions: RDCR can act as a safe alternative delivery mode of cardiac rehabilitation (CR). The low long-term rates of reported SAEs and re-hospitalization incidences of the RDCR could enhance the uptake rates of CR interventions. However, further investigation is needed in larger populations and longer assessment points.

Efficacy of supervised home-based, real time, videoconferencing telerehabilitation in patients with type 2 diabetes: a single-blind randomized controlled trial.

BACKGROUND: Exercise-based interventions prevent or delay symptoms and complications of type 2 diabetes (T2D) and are highly recommended for T2D patients; though with very low participation rates. Τelerehabilitation (TR) could act as an alternative to overcome the barriers preventing the promotion of T2D patients' well-being. AIM: Determine the effects of a six-week TR program on glycemic control, functional capacity, muscle strength, PA, quality of life and body composition in patients with T2D. DESIGN: A multicenter randomized, single-blind, parallel-group clinical study. SETTING: Clinical trial. POPULATION: Patients with T2D. METHODS: Thirty T2D patients (75% male, 60.1±10.9 years) were randomly allocated to an intervention group (IG) and a control group (CG) with no exercise intervention. IG enrolled in a supervised, individualized exercise program (combination of aerobic and resistance exercises), 3 times/week for 6 weeks at home via a TR platform. Glycated hemoglobin (HbA1c), six-minute walk test (6MWT), muscle strength (Hand Grip Strength Test [HGS], 30-Second Chair Stand test [30CST] physical activity [IPAQ-SF]), quality of life (SF-36) and anthropometric variables were assessed. RESULTS: Two-way repeated-ANOVA showed a statistically significant interaction between group, time and test differences (6MWT, muscle strength) (V=0.33, F [2.17]=4.14, P=0.03, partial η2=0.22). Paired samples t-test showed a statistically significant improvement in HbA1c (Z=-2.7), 6MWT (Μean ∆=-36.9±27.2 m, t=-4.5), muscle strength (Μean ∆=-1.5±1.4 kg, t=-2.22). Similarly, SF-36 (mental health [Μean ∆=-13.3±21.3%], general health [Μean ∆=-11.4±16.90%]) were statistically improved only in IG. CONCLUSIONS: The findings of this study indicate that a 6-week supervised home-based TR exercise program induced significant benefits in patients with T2D, thus enabling telehealth implementation in rehabilitation practice as an alternative approach. CLINICAL REHABILITATION IMPACT: Home-based exercise via the TR platform is a feasible and effective alternative approach that can help patients with T2D eliminate barriers and increase overall rehabilitation utilization.

Translation, Cross-Cultural Adaptation and Psychometric Validation of the Greek Version of the Cardiac Rehabilitation Barriers Scale (CRBS-GR): What Are the Barriers in South-East Europe?

Cardiac Rehabilitation (CR) is a secondary prevention intervention proven to improve quality of life, yet with low participation. The Cardiac Rehabilitation Barriers Scale (CRBS) was developed to assess multi-level barriers to participation. This study aimed at the translation, and cross-cultural adaptation of the CRBS into the Greek language (CRBS-GR), followed by psychometric validation. Some 110 post-angioplasty patients with coronary artery disease (88.2% men, age 65.3 ± 10.2 years) answered the CRBS-GR. Factor analysis was performed to obtain the CRBS-GR subscales/factors. The internal consistency and 3-week test-retest reliability was evaluated using Cronbach's alpha (α) and intraclass correlation coefficient (ICC), respectively. Construct validity was tested via convergent and divergent validity. Concurrent validity was assessed with the Hospital Anxiety and Depression Scale (HADS). Translation and adaptation resulted in 21 items similar to the original version. Face validity and acceptability were supported. Construct validity assessment revealed four subscales/factors, with acceptable overall reliability (α = 0.70) and subscale internal consistency for all but one factor (α range = 0.56-0.74). The 3-week test-retest reliability was 0.96. Concurrent validity assessment demonstrated a small to moderate correlation of the CRBS-GR with the HADS. The greatest barriers were the distance from the rehabilitation center, the costs, the lack of information about CR, and already exercising at home. The CRBS-GR is a reliable and valid tool for identifying CR barriers among Greek-speaking patients.

Tele-Assessment of Functional Capacity through the Six-Minute Walk Test in Patients with Diabetes Mellitus Type 2: Validity and Reliability of Repeated Measurements.

A tele-assessed 6MWT (TL 6MWT) could be an alternative method of evaluating functional capacity in patients with diabetes mellitus type 2 (DM2). This study aimed to assess the validity and reliability of a TL 6MWT. The functional capacity of 28 patients with DM2 (75% men) aged 61 ± 13 years was evaluated twice via an indoor, center-based 6MWT (CB 6MWT) and twice outside each patient's home via a web-based platform TL 6MWT. The study showed a high statistically significant correlation between the CB and TL 6MWT (Pearson's r = 0.76, p < 0.001). Reliability testing showed no statistically significant differences in the distance covered (CB1: 492 ± 84 m and CB2: 506 ± 86 m versus TL1: 534 ± 87 m and TL2: 542 ± 93 m, respectively) and in the best distance of the TL 6MWT (545 ± 93 m) compared to the best CB distance (521 ± 83 m). Strong internal reliability for both the CB (intraclass correlation coefficient (ICC) = 0.93) and the TL 6MWT (ICC = 0.98) was found. The results indicate that a TL 6MWT performed outdoors can be a highly valid and reliable tool to assess functional capacity in patients with DM2. No learning effect between the TL and CB assessment was found, minimizing the need for repetition.

Randomized Controlled Trial of Group Exercise Intervention for Fall Risk Factors Reduction in Nursing Home Residents.

OBJECTIVE: The aim of this study was to assess the effectiveness of a multidimensional exercise intervention on improving fall risk deterrent factors, such as overall strength and flexibility in nursing home residents. METHODS: A multi-centre, randomized controlled trial was finally utilized in 40 older adults (>65 years) who were randomly allocated to the intervention or the control group (20 subjects in each). The intervention group attended an exercise program twice a week for eight weeks, to improve functional mobility. The control group did not receive any intervention. Measurements before and after intervention included the Hand Grip Strength (HGS) testing, the Sit-to-Stand test (SST), the Back Scratch Test (BST), and the Sit-and-Reach test (SRT). RESULTS: MANOVA revealed significant time effects, V = 0.336, F(6, 33) = 2.78, p = 0.027, partial η2 = 0.336; group effects, V = 0.599, F(6, 33) = 8.22, p < 0.001, partial η2 = 0.599; and group*time interaction, V = 0.908, F(6, 33) = 54.52, p < 0.001, partial η2 = 0.908. A subsequent univariate analysis did not reveal a significant time effect for any variable (p > 0.05). Significant group effects were observed only for SRT (p < 0.05). Significant group*time interactions were observed for all the examined variables (p < 0.05). Dependent t-tests showed that the older adults in the exercise group were significantly improved in all the examined parameters (p < 0.05). Except for SRT (p > 0.05), all the other parameters significantly deteriorated in the control group (p < 0.05). CONCLUSIONS: Significant improvements were demonstrated in strength and flexibility among nursing home residents following an eight-week group exercise training program.

Effectiveness of Home-Based Cardiac Rehabilitation, Using Wearable Sensors, as a Multicomponent, Cutting-Edge Intervention: A Systematic Review and Meta-Analysis.

Exercise-based cardiac rehabilitation is a highly recommended intervention towards the advancement of the cardiovascular disease (CVD) patients' health profile; though with low participation rates. Although home-based cardiac rehabilitation (HBCR) with the use of wearable sensors is proposed as a feasible alternative rehabilitation model, further investigation is needed. This systematic review and meta-analysis aimed to evaluate the effectiveness of wearable sensors-assisted HBCR in improving the CVD patients' cardiorespiratory fitness (CRF) and health profile. PubMed, Scopus, Cinahl, Cochrane Library, and PsycINFO were searched from 2010 to January 2022, using relevant keywords. A total of 14 randomized controlled trials, written in English, comparing wearable sensors-assisted HBCR to center-based cardiac rehabilitation (CBCR) or usual care (UC), were included. Wearable sensors-assisted HBCR significantly improved CRF when compared to CBCR (Hedges' g = 0.22, 95% CI 0.06, 0.39; I2 = 0%; p = 0.01), whilst comparison of HBCR to UC revealed a nonsignificant effect (Hedges' g = 0.87, 95% CI -0.87, 1.85; I2 = 96.41%; p = 0.08). Effects on physical activity, quality of life, depression levels, modification of cardiovascular risk factors/laboratory parameters, and adherence were synthesized narratively. No significant differences were noted. Technology tools are growing fast in the cardiac rehabilitation era and promote exercise-based interventions into a more home-based setting. Wearable-assisted HBCR presents the potential to act as an adjunct or an alternative to CBCR.

Efficacy, efficiency and safety of a cardiac telerehabilitation programme using wearable sensors in patients with coronary heart disease: the TELEWEAR-CR study protocol.

INTRODUCTION: Exercise-based cardiac rehabilitation (CR) is a beneficial tool for the secondary prevention of cardiovascular diseases with, however, low participation rates. Telerehabilitation, intergrading mobile technologies and wireless sensors may advance the cardiac patients' adherence. This study will investigate the efficacy, efficiency, safety and cost-effectiveness of a telerehabilitation programme based on objective exercise telemonitoring and evaluation of cardiorespiratory fitness. METHODS AND ANALYSIS: A supervised, parallel-group, single-blind randomised controlled trial will be conducted. A total of 124 patients with coronary disease will be randomised in a 1:1 ratio into two groups: intervention telerehabilitation group (TELE-CR) (n=62) and control centre-based cardiac rehabilitation group (CB-CR) (n=62). Participants will receive a 12-week exercise-based rehabilitation programme, remotely monitored for the TELE-CR group and standard supervised for the CB-CR group. All participants will perform aerobic training at 70% of their maximal heart rate, as obtained from cardiopulmonary exercise testing (CPET) for 20 min plus 20 min for strengthening and balance training, three times per week. The primary outcomes will be the assessment of cardiorespiratory fitness, expressed as peak oxygen uptake assessed by the CPET test and the 6 min walk test. Secondary outcomes will be the physical activity, the safety of the exercise intervention (number of adverse events that may occur during the exercise), the quality of life, the training adherence, the anxiety and depression levels, the nicotine dependence and cost-effectiveness. Assessments will be held at baseline, end of intervention (12 weeks) and follow-up (36 weeks). ETHICS AND DISSEMINATION: The study protocol has been reviewed and approved by the Ethics Committee of the University of Thessaly (1108/1-12-2021) and by the Ethics Committee of the General University Hospital of Larissa (3780/31-01-2022). The results of this study will be disseminated through manuscript publications and conference presentations. TRIAL REGISTRATION NUMBER: NCT05019157.

Safety of home-based cardiac rehabilitation: A systematic review.

BACKGROUND: Cardiac rehabilitation is an evidence-based intervention that aims to improve health outcomes in cardiovascular disease patients, but it is largely underutilized. One strategy for improving utilization is home-based cardiac rehabilitation (HBCR). Previous research has shown that HBCR programs are feasible and effective. However, there is a lack of evidence on safety issues in different cardiac populations. This systematic review aimed to provide an evidence-based overview of the safety of HBCR. OBJECTIVES: To examine the incidence and severity of adverse events of HBCR. METHODS: The following databases were searched: CINAHL, The Cochrane Library, Embase, MEDLINE, PubMed, Web of Science, Global Health, and Chinese BioMedical Literature Database for randomized controlled trials. The included trials were written in English and analyzed the incidence of adverse events (AEs) as a primary or secondary intervention outcome. RESULTS: Five studies showed AEs incidence, of which only one study reported severe AE associated with HBCR exercise. The incidence rate of severe AEs from the sample (n = 808) was estimated as 1 per 23,823 patient-hour of HBCR exercise. More than half patients included were stratified into a high-risk group. In the studies were found no deaths or hospitalizations related to HBCR exercise. CONCLUSION: The risk of AEs during HBCR seems very low. Our results concerning the safety of HBCR should induce cardiac patients to be more active in their environment and practice physical exercise regularly.

Exercise-based cardiac rehabilitation programs in the era of COVID-19: a critical review.

Cardiovascular diseases are the leading cause of morbidity and mortality worldwide. Increased rates of morbidity and mortality have led to the increased need for the implementation of secondary prevention interventions. Exercise-based cardiac rehabilitation (CR) represents a multifactorial intervention, including elements of physical exercise and activity, education regarding healthy lifestyle habits (smoking cessation, nutritional habits), to improve the physical capacity and psychological status of cardiac patients. However, participation rates in CR programs remain low due to socioeconomic, geographical and personal barriers. Recently the COVID-19 pandemic restrictions have added another barrier to CR programs. Therefore there is an emerging need to further improve the types and methods of implementing CR. Cardiac telerehabilitation, integrating advanced technology for both monitoring and communicating with the cardiac population, appears to be an innovative CR alternative that can overcome some of the barriers preventing CR participation. This review paper aims to describe the background and core components of center-based CR and cardiac telerehabilitation, and discuss their implications for present day clinical practice and their future perspectives.
