Cardiac Rehabilitation Based on the Walking Test and Telerehabilitation Improved Cardiorespiratory Fitness in People Diagnosed with Coronary Heart Disease during the COVID-19 Pandemic

Physiotherapists' Adoption and Perceptions of Tele-Rehabilitation for Cardiorespiratory Care in Response to COVID-19

Purpose

The use of tele-rehabilitation as a mode for physiotherapy services was widely implemented following the onset of the coronavirus disease 2019 (COVID-19) pandemic. This study explored the perceived value and experiences of physiotherapists relating to tele-rehabilitation for cardiorespiratory care.

Method

Semi-structured interviews were conducted with physiotherapists who provided tele-rehabilitation to adults with cardiorespiratory conditions between March 11 and December 31, 2020. Interviews were analyzed using conventional content analysis.

Results

Seven participants were interviewed; six practising solely in pulmonary rehabilitation and one practising in both pulmonary and cardiac rehabilitation. Three major themes emerged: (1) the pandemic presented unique challenges to implementing tele-rehabilitation while exacerbating previous challenges inherent with virtual care, (2) tele-rehabilitation use during the pandemic was deemed as equally effective in quality of care and patient adherence when compared to in-person services, and (3) tele-rehabilitation had significant value during the pandemic and has potential as an alternative delivery model post pandemic.

Conclusion

Despite the inherent challenges, tele-rehabilitation was endorsed by participants as a suitable and effective alternative to care delivery and holds promise as a post-pandemic delivery model. Further evaluation is needed to support and optimize tele-rehabilitation use in physiotherapy practice.

Telerehabilitation: Exploring the Untapped Potential

Telerehabilitation is a burgeoning field that holds immense promise in revolutionizing the delivery of rehabilitation services. Defined as a branch of telecommunication utilizing technologies such as the internet, it facilitates remote interaction between healthcare providers and patients, transcending geographical barriers. This method proves invaluable in patient assessment, counseling, and treatment across various medical domains, including physical therapy, speech therapy, psychotherapy, and occupational therapy. Particularly beneficial for individuals with disabilities or those unable to access traditional healthcare facilities, telerehabilitation mitigates the constraints of time and cost associated with travel. This paper explores the evolution, types, uses, and research findings in telerehabilitation, shedding light on its transformative potential in health care.

Validity and reliability of automated treadmill six-minute walk test in patients entering exercise-based cardiac rehabilitation

Introduction: The six-minute walk test (6MWT) is a well-established tool for assessing submaximal functional capacity for cardiac patients, but space limitations challenge its implementation. Treadmill-based (TR) 6MWT is a promising alternative, but it requires patients to complete a familiarization test to adapt treadmill speed regulation. With the advancement of sensors, it is possible to automatically control speed for individual patients and thus overcome the space limitation or the speed control difficulty on the treadmill for each patient.Methods: This study investigated the validity and interchangeability of automated speed TR6MWT and standard hallway (HL) 6MWT. Eighteen patients were assessed at baseline of the 12-week cardiac rehabilitation program. Fourteen of them were assessed after rehabilitation. All patients performed three TR6MWTs and three HL6MWTs at baseline and one of each test after the program.Results: Patients well tolerated the TR6MWT. There was a strong correlation between both test methods (r = 0.79). However, patients performed significantly better in HL6MWT (514.8m ± 59.7m) than in TR6MWT (447.2 ± 79.1m) with 95% CI, 40.4-94.6m, p < 0.05. Both tests showed high test-retest reliability (intraclass correlation coefficient of 0.86). The TR6MWT showed a valuable comparison of the effect of the cardiac rehabilitation program (20% increase, effect size 1.1) even though it is not interchangeable with the HL6MWT.Conclusion: The automated speed TR6MWT appears to be an acceptable tool with adequate validity, reliability, and responsiveness for assessing functional capacity in patients utilizing cardiac rehabilitation programs.

Remote cardiac rehabilitation program during the COVID-19 pandemic for patients with stable coronary artery disease after percutaneous coronary intervention: a prospective cohort study

OBJECTIVE

The coronavirus disease-19 (COVID-19) pandemic restricts rapid implementation of in-person delivery of cardiac rehabilitation (CR) at the center for coronary artery disease (CAD) patients undergoing percutaneous coronary intervention (PCI), thus enabling a cohort comparison of in-person vs. remote CR program. This study aims to investigate outcomes of exercise capacity, health-related quality of life (HRQL), mental health, and family burden of stable CAD patients undergoing PCI in low-to-moderate risk after different delivery models of CR program.

METHODS

The study included a cohort of stable CAD patients undergoing PCI who had experienced two naturally occurring modes of CR program after hospital discharge at two time periods, January 2019 to December 2019 (in-person CR program) and May 2020 to May 2021 (remote CR program). The exercise capacity was assessed by means of 6-min walk test (6MWT), maximal oxygen uptake (VO₂max) and the respiratory anaerobic threshold (VO_2AT) before discharge, at the end of the 8-week and 12-week in-person or remote CR program after discharge.

RESULTS

No adverse events occurred during the CR period. CAD patients had a longer distance walked in 6 min with a higher VO_2max after 8-week and 12-week CR program whether in-person or remote model (p < 0.05). The distance walked in 6 min was longer and the maximal oxygen uptake (VO₂max) was higher at the end of the 12-week in-person or remote CR program than 8-week in-person or remote CR program (p < 0.05). The respiratory anaerobic threshold (VO_2AT) of CAD patients was decreased after 8-week CR program whether in-person or remote model (p < 0.05). CAD patients receiving remote CR program exhibited higher HRQL scores in domains of vitality (p = 0.048), role emotional (p = 0.039), mental health (p = 0.014), and the summary score of the mental composite (p = 0.048) compared to in-person CR program after 8 weeks. The anxiety and depression scores of CAD patients undergoing PCI were decreased after 8-week CR program whether in-person or remote model (p < 0.05). The CAD patients receiving remote delivery showed lower anxiety and depression scores compared to those receiving in-person delivery at the end of the 8-week CR program (p < 0.05). It was found that the family burden scores of CAD patients undergoing PCI were reduced after 8-week and 12-week CR program whether in-person or remote model (p < 0.05). The CAD patients receiving remote CR program showed lower family burden scores than those receiving in-person CR program after whether 8 weeks or 12 weeks (p < 0.05).

CONCLUSION

These data indicate that a properly designed and monitored remote delivery represents a feasible and safe model for low-to-moderate-risk, stable CAD patients undergoing PCI inaccessible to in-person CR during the COVID-19 pandemic.

Role of wearable devices in cardiac telerehabilitation: A scoping review

BACKGROUND

Cardiac rehabilitation (CR) is an evidence-based comprehensive program that includes exercise training, health education, physical activity promotion, and extensive counseling for the management of cardiovascular risk factors. Wearable devices monitor certain physiological functions, providing biometric data such as heart rate, movement, sleep, ECG analysis, blood pressure, energy expenditure, and numerous other parameters. Recent evidence supports wearable devices as a likely relevant component in cardiovascular risk assessment and disease prevention. The purpose of this scoping review is to better understand the role of wearable devices in home-based CR (HBCR) and to characterize the evidence regarding the incorporation of wearable devices in HBCR programs and cardiovascular outcomes.

METHODS & FINDINGS

We created a search strategy for multiple databases, including PubMed, Embase (Elsevier), CINAHL (Ebsco), Cochrane CENTRAL (Wiley), and Scopus (Elsevier). Studies were included if the patients were eligible for CR per Medicare guidelines and >18 years of age and if some type of wearable device was utilized during HBCR. Our search yielded 57 studies meeting all criteria. The studies were classified into 4 groups: patients with coronary heart disease (CHD) without heart failure (HF); patients with HF; patients with heart valve repair or replacement; and patients with exposure to center-based CR. In three groups, there was an upward trend toward improvement in quality of life (QOL) and peak VO2, less sedentary time, and an increase in daily step count in the intervention groups compared to control groups.

CONCLUSIONS

HBCR using wearable devices can be a comparable alternative or adjunct to center-based CR for patients with CHD and HF. More studies are needed to draw conclusions about the comparability of HBCR to center-based CR in patients with heart valve repair or replacement.

A Pilot, Virtual Exercise Intervention Improves Health and Fitness during the COVID-19 Pandemic

Physical activity levels are low in individuals with chronic disease (e.g., obesity) and have worsened during the COVID-19 pandemic.

PURPOSE

Our pilot study tested a virtual exercise intervention for rural-dwelling adults with chronic disease from January-April 2021 for changes in mental health, physical fitness, and physical activity and for intervention fidelity.

METHODS

Participants (n = 8 [7 female]; age = 57.5 ± 13.8 years, body mass index = 38.2 ± 8.0 kg/m²) completed an exercise intervention led virtually by collegiate health science majors. Participants attended two 60-minute sessions/week for 12 weeks, completing individually-tailored and progressed aerobic and muscle-strengthening training. A non-randomized control group matched on gender and age continued normal activity during the 12 weeks. Changes in mental health, physical fitness, and physical activity measures were evaluated using a 2×2 (group × time) analysis of covariance.

RESULTS

Both groups improved mental health, but only intervention participants lost weight (3.1 ± 1.0 kg; no change in controls). Step test, arm curls, and chair stands improved by 16.1-20.6% in the intervention and 7.8-12.1% in the control groups. Intervention participants did not increase overall physical activity during or after the intervention. Intervention fidelity was high; participants attended ~73% of sessions and rated the sessions 4.7 ± 0.6 (out of 5). Researcher observations rated exercise sessions as meeting 12.7 ± 0.6 of 16 goals.

CONCLUSIONS

Our virtual exercise program was associated with positive mental health and physical fitness changes. Such programs may provide a method, even beyond the pandemic, to improve fitness in adults with chronic disease.

Efficacy of an asynchronous telerehabilitation program in post-COVID-19 patients: A protocol for a pilot randomized controlled trial

Background

About 40% of patients who have had COVID-19 still have symptoms three months later whereas a 10% may experience physical and/or psychological consequences two years later. Therefore, it is necessary to perform preventive interventions when patients are discharged from the hospital to decrease the aforementioned sequelae. The purpose of this pilot-controlled trial will be to determine the efficacy of a rehabilitation program on functional status and psychosocial factors for post-COVID-19 patients when it is delivered through a tele-care platform versus a booklet-based rehabilitation.

Methods

The estimated sample size will be of 50 participants who have been discharged after COVID-19 and have a level of fatigue equal or greater than 4 on the Fatigue Severity Scale. The primary outcome will be the severity of fatigue. Participants will be randomly allocated to an “asynchronous telerehabilitation group” or to a “booklet-based rehabilitation group”. Treatment in both groups will be the same and will consist of a combination of therapeutic exercise and an educative program. Treatment outcomes will be evaluated the last day of the intervention and at three- and six-months follow-up.

Discussion

The telerehabilitation intervention appears to be a viable and efficacy option in decreasing severe fatigue and other fitness variables such as strength and aerobic capacity, similar to other traditional rehabilitation formats such as through an explanatory booklet.

Clinical trial registration

This trial has been prospectively registered at clinialtrials.gov identifier: NCT04794036.

Efficacy and Safety of Hybrid Cardiac Telerehabilitation in Patients with Hypertrophic Cardiomyopathy without Left Ventricular Outflow Tract Obstruction and Preserved Ejection Fraction—A Study Design

Hypertrophic cardiomyopathy (HCM) is the most common congenital disease increasing the risk of sudden cardiac death. For many years, HCM patients were excluded from exercise training. However, there are data showing that patients with HCM undergoing supervised exercise training could improve physical performance without serious adverse events. A project was designed as a randomized clinical trial to assess the effectiveness and safety of hybrid cardiac rehabilitation (HCR)—a combination of hospital-based cardiac rehabilitation (1 month) with a new form of home-based telemonitored cardiac rehabilitation (2 months) in HCM patients without left ventricular (LV) outflow tract obstruction and preserved systolic function. Sixty patients who fulfil the inclusion criteria have been randomly assigned (1:1) to either HCR plus usual care (training group) or usual care only (control group). The primary endpoint is a functional capacity evaluated by peak oxygen uptake (pVO2). Secondary endpoints include workload time during the cardiopulmonary exercise testing, a six-minute walk test distance, NT-pro BNP level, echocardiographic parameters of the left ventricular diastolic function (E/A, E/e’, myocardial strain rate), right ventricular systolic pressure, a gradient in the LV outflow tract, and quality of life. The tertiary analysis includes safety, acceptance and adherence to the HCR program. Our research will provide innovative data on the effectiveness and safety of hybrid cardiac rehabilitation in HCM patients without LV outflow tract obstruction and preserved systolic function.

Incremental shuttle walking test to assess functional capacity in cardiac rehabilitation: a narrative review

Background/Aims

Low functional capacity has been recognised to be the most important predictor of overall mortality compared to all other cardiovascular risk factors in patients with cardiovascular disease. Walk tests, such as the incremental shuttle walking test and the 6-Minute Walk Test, are used to assess functional capacity in patients, the effectiveness of a cardiac rehabilitation programme and the prognosis of cardiovascular diseases. The aim of this review was to provide a narrative review of the literature and identify the key features of the incremental shuttle walking test as a measure of functional capacity testing in cardiac rehabilitation patients.

Methods

The PubMed, MEDLINE, Elsevier and Google Scholar databases were searched for relevant scientific articles published up to March 2021 with no restriction on start day. The key words defined by researchers were ‘incremental shuttle walking test’, ‘exercise test’, ‘functional capacity’, ‘cardiovascular disease’, ‘cardiac rehabilitation’, ‘reliability’ ‘prediction; ‘walk tests’. A final set of 31 articles was included in this narrative review.

Results

Evidence-based findings suggest that the incremental shuttle walking test is a valid, reliable, sensitive, useful tool for detecting and predict cardiorespiratory capacity.

Conclusions

Clinicians can be confident that they can use the incremental shuttle walking test to monitor changes in functional capacity in patients with cardiovascular disease.

Effects of Cardiac Telerehabilitation During COVID-19 on Cardiorespiratory Capacities in Patients With Coronary Artery Disease

Background

The COVID-19 pandemic led to the closure of most cardiac therapy centers. One of the solutions was to adapt the existing cardiac rehabilitation (CR) program in an institute to a remote approach offered by home-based telerehabilitation. The aim of this study was to measure the cardiorespiratory effects of telerehabilitation compared to conventional center-based CR.

Methods

Patients were assigned to two 3-week CR programs: telerehabilitation and conventional center-based CR. The telerehabilitation group wore a connected watch to monitor heart rate (HR) and gave their perception of effort according to a modified Borg scale. The exercise training (four sessions/week) consisted of 1-h aerobic endurance and strength training session at the target HR zone determined by results based on cardiopulmonary exercise test (CPET) and perception of effort, respectively. The exercise protocol was the same for conventional CR participants except the duration of session that lasted 2 h instead of one. The week before and after the training program, peak oxygen uptake (VO₂ peak), oxygen uptake at first ventilatory threshold (VO₂ at VT₁), peak workload, percent of predicted maximum HR, and the absolute differences in HR and systolic blood pressure between maximum and recovery at 1 and 3 min were measured using a CPET. A two-way ANOVA with one repeated measure and one independent factor was performed.

Results

Fifty-four patients (mean age: 61.5 ± 8.6 years, 10 women) equally split in the two groups were included in this experiment. A significant increase was observed in both groups on VO₂ peak (telerehabilitation: 8.1 ± 7.8% vs. conventional: 10.1 ± 9.7%, p < 0.001), VO₂ at VT₁ (telerehabilitation: 8.8 ± 4.4% vs. conventional: 7.3 ± 19.0%, p = 0.02) and peak workload (telerehabilitation: 16.6 ± 18.9% vs. conventional: 17.2 ± 7.0%, p < 0.001) after the 3-week telerehabilitation and conventional CR, respectively. No significant difference was noticed between both groups.

Conclusion

A 3-week exercise program improved patients’ cardiorespiratory fitness. Telerehabilitation was as effective and represents a safe alternative CR program during the COVID-19 period. In the future, this approach could facilitate the continuity of care for patients unable to participate in center-based CR.

Current role and future perspectives of cardiac rehabilitation in coronary heart disease

Ischaemic heart disease (IHD) is a major cause of morbidity and mortality worldwide. While there have been major advances in this field, these patients are still a higher risk subgroup. As such, strategies to mitigate risk and tailor secondary prevention measures are of the utmost relevance. Cardiac rehabilitation (CR), encompassing several domains including exercise training, cardiovascular risk factor optimization, nutritional and psychological assessments, as well as other ancillary interventions has shown to be one of the pillars in the contemporary management of patients with IHD. Indeed, CR is associated with several benefits in this population, ranging from functional capacity to improvements in outcomes. Whilst this, there are still several issues concerning the optimal application of CR which are still not fully ascertained, such as lack of referral and completion, as well as questions related to programme design (particularly among patients with multiple comorbidities). In this review, we aim at presenting a pragmatic overview on the current role of CR in the management of individuals with IHD, while also discussing some of the caveats in the current data, as well as future concepts which could help improve the uptake and personalization of this pivotal time-tested intervention.

COVID-19 and Cardiovascular Disease: a Global Perspective

PURPOSE OF REVIEW

This review aims to assess the global impact of the COVID-19 pandemic on the cardiovascular diseases (CVDs), trying to assess the possible future trajectory of the CVDs and their management.

RECENT FINDINGS

The COVID-19 pandemic has had a deleterious impact on the CV risk factors, with an increase in both sedentary and unhealthy food habits. The fear of contagion has decreased the access to the emergency systems with an increase in out-of-hospital-cardiac-arrests and late presentation of acute myocardial infarctions. The closure of the non-urgent services has delayed cardiac rehabilitation programmes and chronic clinical care. As a result of the COVID-19 pandemic impact on the population habits and on the management of CVDs, we will probably face an increase in CVD and heart failure cases. It is crucial to use all the non-traditional approaches, such as telemonitoring systems, in order to overcome the difficulties raised by the pandemic.
