Patients' Perceptions of Hybrid and Virtual-Only Care Models During the Cardiac Rehabilitation Patient Journey: A Qualitative Study.

The COVID-19 pandemic initially led to discontinuation of the "traditional" center-based cardiac rehabilitation (CR) model. Virtual models emerged as an opportunity to deliver care, with many programs continuing to offer these models. The aim of this study was to explore patients' perceptions of virtual models of either hybrid (combining center-based and virtual) or virtual-only CR since the pandemic. Men and women who chose to participate in hybrid or virtual CR models between January 2022 and January 2023 were invited to attend 1 of 8 focus group sessions. Focus groups were conducted online until thematic saturation was reached. Transcripts were analyzed using thematic analysis. Twenty-three patients (48% female; 83% attending hybrid CR) participated in the study. Analysis revealed 12 overarching themes associated with the CR patient journey: pre-CR, namely, (1) importance of endorsement from healthcare providers and (2) need for education/communication while waiting for program initiation; during CR, namely, (3) preference for class composition/structure, (4) need to enhance peer support in the virtual environment, (5) convenience and concerns with virtual sessions, (6) necessity of on-site sessions, (7) safety of the exercise prescription, (8) requirement/obligation for allied health offerings, (9) satisfaction with virtual education, and (10) use of technology to facilitate CR participation; and post-CR, namely, (11) acknowledgment of program completion and (12) need for support/education after program graduation. Patients require ongoing support from time of referral to beyond CR program completion. Physical, psychosocial, nutritional, and educational supports are needed. Perceptions expressed by patients related to the program model are modifiable, and strategies to address these perceptions should be explored.

Implementation of Home-based Cardiac Rehabilitation Program in Patients with Coronary Artery Disease: A Literature Review

Introduction: Coronary artery disease (CAD) is the major cause of disability and death worldwide. The cardiac rehabilitation (CR) program is the management strategy for CAD patients with exercise as the main component to increase functional capacity. This program has been proven beneficial in reducing mortality and morbidity due to CAD. It also reduced the healthcare burden and improved the quality of life. Although the benefits of CR are widely proven, participation and adherence of CAD patients to this program are low. The home-based cardiac rehabilitation (HBCR) program is the strategy developed to increase the coverage of CR services. This program is equally effective as center-based cardiac rehabilitation (CBCR) and is considered safe. This review aimed to find out more about the HBCR program with a focus on its implementation in CAD patients.
 Methods: Original articles and systematic or narrative reviews were searched using PubMed, Google Scholar, and Research Gate databases. Further exploration of literature citations was also done to meet the inclusion criteria needed to explain the topic.
 Results: Compared to CBCR, the HBCR program provide comparable benefits, both in medical and functional outcomes. The HBCR program is proven to be feasible and safe with better adherence. The components of the HBCR program are generally the same as the CBCR program and direct supervision given in the CBCR program can be replaced by remote supervision through communication devices or home visits.
 Conclusion: The HBCR program can be used as an alternative to CBCR in managing patients with CAD.

Home health care and cardiac rehabilitation following major cardiac surgeries in Pakistan.

Cardiovascular disorders are a leading cause of morbidity and mortality globally, and coronary artery bypass graft surgery is one of the most effective procedures for coronary artery disease. Cardiac rehabilitation (CR) has been shown to offer benefits beyond reducing mortality and morbidity rates, including enhancing patients' quality of life and reducing healthcare costs. Home-based CR programs offer personalized plans tailored to individual needs and availability and have been shown to be more effective in sustaining improvements than center-based CR programs. However, there are challenges associated with providing home care services in developing countries, including personnel shortages, lack of financing and policies, and limited access to end-of-life or hospice services. The use of multidisciplinary telehealth and telecare homecare programs that make use of web-based technologies to monitor postoperative outcomes in patients undergoing cardiac surgery may provide a solution to some of these challenges. This manuscript emphasizes the potential of home health care and CR in improving postoperative outcomes in Pakistan and identifies some of the challenges and potential solutions associated with providing home care services.

Cardio4Health Study, a Cardiac Telerehabilitation Pilot Program Aimed at Patients After an Ischemic Event: Cross-sectional Study.

Center-based cardiac rehabilitation programs (CRPs) reduce morbidity and mortality after an ischemic cardiac event; however, they are widely underused. Home-based CRP has emerged as an alternative to improve patient adherence; however, its safety and efficacy remain unclear, especially for older patients and female patients. This study aimed to develop a holistic home-based CRP for patients with ischemic heart disease and evaluate its safety and impact on functional capacity, adherence to a healthy lifestyle, and quality of life. The 8-week home-based CRP included patients of both sexes, with no age limit, who had overcome an acute myocardial infarction in the previous 3 months, had a left ventricular ejection fraction of ≥40%, and had access to a tablet or mobile device. The CRP was developed using a dedicated platform designed explicitly for this purpose and included 3 weekly exercise sessions combining tailored aerobic and strength training and 2 weekly educational session focused on lifestyle habits, therapeutic adherence, and patient empowerment. We initially included 62 patients, of whom 1 was excluded for presenting with ventricular arrhythmias during the initial stress test, 5 were excluded because of incompatibility, and 6 dropped out because of a technological barrier. Ultimately, 50 patients completed the program: 85% (42/50) were male, with a mean age of 58.9 (SD 10.3) years, a mean left ventricular ejection fraction of 52.1% (SD 6.72%), and 25 (50%) New York Heart Association functional class I and 25 (50%) New York Heart Association II-III. The CRP significantly improved functional capacity (+1.6 metabolic equivalent tasks), muscle strength (arm curl test +15.5% and sit-to-stand test +19.7%), weekly training volume (+803 metabolic equivalent tasks), adherence to the Mediterranean diet, emotional state (anxiety), and quality of life. No major complications occurred, and adherence was excellent (>80%) in both the exercise and educational sessions. In the subgroup analysis, CRP showed equivalent beneficial effects irrespective of sex and age. In addition, patient preferences for CRP approaches were equally distributed, with one-third (14/50, 29%) of the patients preferring a face-to-face CRP, one-third (17/50, 34%) preferring a telematic CRP, and one-third (18/50, 37%) preferring a hybrid approach. Regarding CRP duration, 63% (31/50) of the patients considered it adequate, whereas the remaining 37% (19/50) preferred a longer program. A holistic telematic CRP dedicated to patients after an ischemic cardiac event, irrespective of sex and age, is safe and, in our population, has achieved positive results in improving maximal aerobic capacity, weekly training volume, muscle strength, quality of life, compliance with diet, and anxiety symptoms. The preference for a center- or home-based CRP approach is diverse among the study population, emphasizing the need for a tailored CRP to improve adherence and completion rates.

Effectiveness of eHealth Interventions on Moderate-to-Vigorous Intensity Physical Activity Among Patients in Cardiac Rehabilitation: Systematic Review and Meta-analysis

Cardiac rehabilitation is a class IA recommendation for patients with cardiovascular diseases. Physical activity is the core component and core competency of a cardiac rehabilitation program. However, many patients with cardiovascular diseases are failing to meet cardiac rehabilitation guidelines that recommend moderate-to-vigorous intensity physical activity. The major objective of this study was to review the evidence of the effectiveness of eHealth interventions in increasing moderate-to-vigorous intensity physical activity among patients in cardiac rehabilitation. The secondary objective was to examine the effectiveness of eHealth interventions in improving cardiovascular-related outcomes, that is, cardiorespiratory fitness, waist circumference, and systolic blood pressure. A comprehensive search strategy was developed, and a systematic search of 4 electronic databases (PubMed, Web of Science, Embase, and Cochrane Library) was conducted for papers published from the start of the creation of the database until November 27, 2022. Experimental studies reporting on eHealth interventions designed to increase moderate-to-vigorous intensity physical activity among patients in cardiac rehabilitation were included. Multiple unblinded reviewers determined the study eligibility and extracted data. Risk of bias was evaluated using the Cochrane Collaboration Tool for randomized controlled trials and the Cochrane Effective Practice and Organization of Care group methods for nonrandomized controlled trials. A random-effect model was used to provide the summary measures of effect (ie, standardized mean difference and 95% CI). All statistical analyses were performed using Stata 17. We screened 3636 studies, but only 29 studies were included in the final review, of which 18 were included in the meta-analysis. The meta-analysis demonstrated that eHealth interventions improved moderate-to-vigorous intensity physical activity (standardized mean difference=0.18, 95% CI 0.07-0.28; P=.001) and vigorous-intensity physical activity (standardized mean difference=0.2, 95% CI 0.00-0.39; P=.048) but did not improve moderate-intensity physical activity (standardized mean difference=0.19, 95% CI -0.12 to 0.51; P=.23). No changes were observed in the cardiovascular-related outcomes. Post hoc subgroup analyses identified that wearable-based, web-based, and communication-based eHealth intervention delivery methods were effective. eHealth interventions are effective at increasing minutes per week of moderate-to-vigorous intensity physical activity among patients in cardiac rehabilitation. There was no difference in the effectiveness of the major eHealth intervention delivery methods, thereby providing evidence that in the future, health care professionals and researchers can personalize convenient and affordable interventions tailored to patient characteristics and needs to eliminate the inconvenience of visiting center-based cardiac rehabilitation programs during the COVID-19 pandemic and to provide better support for home-based maintenance of cardiac rehabilitation.

Comparing Virtual and Center-Based Cardiac Rehabilitation on Changes in Frailty.

Many patients with cardiovascular disease (CVD) are frail. Center-based cardiac rehabilitation (CR) can improve frailty; however, whether virtual CR provides similar frailty improvements has not been examined. To answer this question, we (1) compared the effect of virtual and accelerated center-based CR on frailty and (2) determined if admission frailty affected frailty change and CVD biomarkers. The virtual and accelerated center-based CR programs provided exercise and education on nutrition, medication, exercise safety, and CVD. Frailty was measured with a 65-item frailty index. The primary outcome, frailty change, was analyzed with a two-way mixed ANOVA. Simple slopes analysis determined whether admission frailty affected frailty and CVD biomarker change by CR model type. Our results showed that admission frailty was higher in center-based versus virtual participants. However, we observed no main effect of CR model on frailty change. Results also revealed that participants who were frailer at CR admission observed greater frailty improvements and reductions in triglyceride and cholesterol levels when completing virtual versus accelerated center-based CR. Even though both program models did not change frailty, higher admission frailty was associated with greater frailty reductions and change to some CVD biomarkers in virtual CR.

Abstract 12889: Sex Differences in Exercise Capacity After Home-Based Cardiac Rehabilitation During the Covid-19 Pandemic

Introduction: Many center-based cardiac rehabilitation programs were forced to close during the pandemic resulting in a programmatic shift to delivering cardiac rehabilitation remotely in the home-based setting. This study examined sex differences in the change of exercise frequency and exercise capacity in patients participating in home-based cardiac rehabilitation (HBCR) during the COVID-19 pandemic. Methods: Retrospective cohort study of 567 HBCR patients between March 2020 and May 2021. Patients who completed the Duke Activity Status Index questionnaire before and after HBCR were included. We calculated the number of reported exercise days/ week, exercise min/day, and VO 2 peak estimated. Patients were divided into two groups according to sex (Male/Female). Continuous data are described as mean±SD and baseline data compared with a two-sample t-test. The delta change from pre-post between groups also are compared with a two-sample t-test. Results: Of 567 HBCR patients, 118 patients completed both pre and post HBCR questionnaires (Male, n=82, 66±12 yo vs Female, n=36, 65±12 yo, p=0.80). There were no differences between groups for baseline exercise days/week or exercise min/day pre HBCR (4.0±2.8 vs 4.1±3.0 days, p=0.87; 22±20 vs 18±20 min, p=0.33); however, VO 2 peak at baseline HBCR was higher in males than females (22.3±8.1 vs 18.9±5.9 ml/kg/min, p<0.05). Both groups improved exercise days/week (4.0±2.8 to 5.7±1.5 vs 4.1±3.0 to 5.7±1.4 days, p<0.05 for both), exercise min/day (22±20 to 40±15 vs 18±20 to 37±21 min, p<0.05 for both), and VO 2 peak (22.3±8.1 to 27.8±8.0 vs 18.9±5.9 to 22.7±6.5, ml/kg/min, p<0.05 for both). In addition, there was no significant difference for the delta change of the three outcomes between groups (1.7±2.7 vs 1.6±2.5 days; 18±19 vs 19±18 min; 5.5±6.5 vs 3.8±4.5 ml/min/kg, p>0.05 for all). Conclusions: Female patients entering HBCR during the COVID-19 pandemic demonstrated lower exercise capacity compared to males; however, both female and male patients increased exercise frequency (days/week and min/day) and exercise capacity (estimated VO 2 peak) similarly after attending HBCR during the COVID-19 pandemic.

Abstract 12849: Impact of Age on Exercise Capacity After Home-Based Cardiac Rehabilitation During the Covid-19 Pandemic

Introduction: The COVID-19 pandemic resulted in the closure of many center-based cardiac rehabilitation programs leading many institutions to rely on home-based cardiac rehabilitation (HBCR) to provide critical secondary cardiovascular disease prevention and rehabilitation. The impact of age on the change of exercise frequency and exercise capacity as a result of HBCR during the COVID-19 pandemic remains unknown. Methods: Retrospective cohort study of 567 HBCR patients between March 2020 and May 2021. Patients who completed the Duke Activity Status Index questionnaire at enrollment and completion of HBCR were included. We calculated the number of reported exercise days/week , exercise min/day, and VO 2 peak estimated. Patients were divided into two groups according to age (Younger<65 y.o; Older≥65 y.o). Continuous data are described as mean ±SD and baseline data compared with a two-sample t-test. The delta change from pre-post between groups also are compared with a two-sample t-test. Results: Of 567 HBCR patients, 118 patients completed both pre and post HBCR questionnaires (Younger, n=54, 56±8 years old vs Older, n=64, 74±7 y.o, p<0.05). Both groups improved exercise days/week (4.4±2.8 to 5.8±1.3 vs 3.8±2.9 to 5.6±1.6 days, p<0.05 for both), exercise min/day (21±20 to 41±17 vs 20±20 to 37±17 min, p<0.05 for both), and VO 2 peak (20.5±7.1 to 27.6±8.0 vs 21.9±8.1 to 25.1±7.7 ml/min/kg, p<0.05 for both). The delta change for exercise days/week and exercise min/day were not significantly different between groups (1.4±2.7 vs 1.9±2.7 days and 19±19 vs 17±18 min, p>0.05); however, the Younger patients significantly increased their VO 2 peak more than the older patients (7.1±6.1 vs 3.2±5.3 ml/min/kg, p<0.05). Conclusions: During the COVID-19 pandemic, exercise frequency (days/week and min/day) and exercise capacity (estimated VO2peak) increased in all patients participating in HBCR. With this, the increase in estimated exercise capacity was greater in younger patients compared with older patients. These findings suggest that additional work is needed to explore factors potentially limiting improvement and strategies to maximize improvement in exercise capacity in older patients participating in HBCR.

Impact of a COmprehensive cardiac REhabilitation framework among high cardiovascular risk cancer survivors: Protocol for the CORE trial

BackgroundCancer survivors are challenging patients, as they often present increased cardiovascular risk. In this background, cardio-oncology rehabilitation frameworks for specific cancer patients have been proposed. However, optimal program designs, as well as their overall safety and efficacy in different subsets of patients, are not fully ascertained. DesignSingle-center, pragmatic, prospective, randomized controlled trial performed in Portugal aiming to evaluate the impact of a center-based cardiac rehabilitation program, consisting of exercise training, nutritional counselling, psychosocial management and lifestyle behavior change, compared to community-based exercise training, in cancer survivors. MethodsAdult cancer survivors (N = 80) exposed to cardiotoxic cancer treatment and/or with previous cardiovascular disease will be randomized (1:1) to receive either an eight-week cardiac rehabilitation program or community-based exercise training. Primary endpoint is cardiorespiratory fitness; secondary endpoints are physical activity, psychosocial parameters, blood pressure, body composition, lipids and inflammatory parameters. Physical function, quality of life, fatigue, health literacy, and feasibility will be assessed; a cost-effectiveness evaluation will also be performed. Between-group differences at baseline and in the change from baseline to the end of the study will be tested with unpaired t-tests or Mann-Whitney U test. Paired t-tests or Wilcoxon signed-rank test will be performed for within-group comparisons. ConclusionThis trial will address the overall impact of a contemporary cardiac rehabilitation program framework in cancer survivors, as compared to a community-based exercise training. Given the higher cardiovascular risk in several groups of cancer patients, our results could provide novel insights into optimized preventive strategies in this complex patient population.

Comparative Assessment of the Long-Term Efficacy of Home-Based Versus Center-Based Cardiac Rehabilitation.

Cardiac rehabilitation programs support the health, wellness, and recovery of patients with cardiovascular conditions. This systematic review attempts to expand these findings while analyzing the latest randomized controlled trials (RCTs) focusing on the long-term advantages of home/center-based cardiac rehabilitation interventions. This study also comparatively analyzes the benefits of opting for home-based cardiac rehabilitation instead of center-based measures to improve the long-term clinical outcomes of cardiac patients. We extracted and analyzed 10 studies (based on 1,549 cardiac patients) concerning the therapeutic efficacy of center/home-based cardiac rehabilitation interventions. The included studies complied with the year range of 2000-2021. The risk of bias assessment was undertaken using the Cochrane Risk-of-Bias tool to evaluate random sequence generation, allocation concealment, blinding of subjects, outcome data completeness, and selective reporting patterns concerning the included RCTs.The findings of our systematic review confirmed the capacity of a home-based cardiac rehabilitation program to effectively improve left ventricular ejection fraction, health-related quality of life, physical fitness, recovery rate, self-efficacy, sedentary lifestyle, physical activity, satisfaction level, functional capacity, social support, and hemodynamic parameters of patients with cardiovascular diseases. Home-based cardiac rehabilitation had the potential to minimize the levels of triglycerides, anxiety, depression, waist circumference, and body mass index/weight of cardiac patients.The results of our systematic review affirmed the long-term therapeutic efficacy of a home-based cardiac rehabilitation program compared to a center-based cardiac rehabilitation program for adult cardiac patients.

Hybrid cardiac rehabilitation – The state of the science and the way forward

Cardiac rehabilitation (CR) improves exercise capacity and health-related quality of life (HRQoL) in a broad range of patients, including those with coronary artery disease, heart failure (HF), after heart valve surgery, and after heart transplantation. Unfortunately, in traditional center-based CR programs participation and adherence are low. A hybrid model of CR, combining center-based and home-based CR services, has been proposed and is currently being studied as a potential way to help bridge the participation gap, while maintaining the beneficial patient outcomes from CR. However, the ideal composition of a hybrid CR program has not been universally agreed upon. In the present review, we define hybrid CR as any combination of supervised center-based and monitored home-based exercise, where at least two of the core components of CR are addressed. Using this definition, we searched for studies comparing hybrid CR with: (1) traditional center-based CR among CAD patients, (2) usual care among CAD patients, and (3) usual care among HF patients. We found nine studies which fit both our definition and comparison groups. The structure of the hybrid CR programs differed for each study, but typically began with a center-based component lasting 2–11 weeks and transitioned to a home-based component lasting 10–22 weeks, with 3–5 exercise sessions per week composed of either walking (usually with a treadmill) or cycling for 25–35 min at 60–75% maximal heart rate. Patients recorded data from home exercise sessions, via either a digital heart rate monitor or accelerometer, into logbooks which were reviewed by a therapist at specified intervals (often via telephone). Counseling on risk factor management was predominantly provided during the center-based component. In these studies, hybrid CR led to similar short-term outcomes compared to traditional CR in patients with coronary artery disease (CAD), as well as increased adherence and reduced delivery costs. Compared with usual care, in patients with CAD, hybrid CR reduced cardiovascular events, and improved lipid profiles, exercise capacity, and HRQoL. In patients with HF, compared with usual care, hybrid CR improved physical function, exercise capacity, and HRQoL. Ongoing studies may clarify the combination of center-based and home-based CR which produces superior outcomes, and may also better define the role that technology should play in CR interventions.

Evidence-Based Review for Cardiac Rehabilitation Program Development Status and Necessity in India

India has a high burden of cardiovascular disease, morbidity and mortality due to CVD has been causing a high economic burden and leading to an overall increase in health care cost. Research evidence from different parts of the world indicates that structured approach to secondary prevention such as cardiac rehabilitation (CR) have health-favoring impact. When CR is supplemented with pharmacological interventions and percutaneous coronary intervention (PCI) has shown a significant improvement in quality of life, reduces morbidity, and mortality rate, cardiac-related parameters, depression and minimizes readmission rates among cardiac patients. Primarily, CR is delivered in three phases: Phase – I begin in the hospital, Phase – II outpatient phase, and Phase – III maintenance phase. Various organizations around the world deliver structured home-based and center-based CR program to cardiac patients also provides training and certification courses in CR to healthcare professionals (HCPs). However, in India, no such organization exists; therefore, CR delivery is under prevalent; further, other factors such as lack of skilled task force, adequate infrastructure, education, and training also contribute for suboptimal use of CR in the country. Awareness among HCPs and patients is also considered one of the primary factors to minimize the uptake of CR program in India. Therefore, there is a great need to revisit the CR delivery protocol and develop an evidence-based uniform approach to increase the uptake of the CR program. Government health care agencies should also frame guidelines to facilitating better infrastructure and training to resulting in increased uptake of CR program among cardiac patients. This review article has compiled various international studies to justify the benefits of CR program development necessity and status in India.

Implementation of Telerehabilitation Interventions for the Self-Management of Cardiovascular Disease: Systematic Review.

BackgroundCoronary heart disease (CHD) is a leading cause of disability and deaths worldwide. Secondary prevention, including cardiac rehabilitation (CR), is crucial to improve risk factors and to reduce disease burden and disability. Accessibility barriers contribute to underutilization of traditional center-based CR programs; therefore, alternative delivery models, including cardiac telerehabilitation (ie, delivery via mobile, smartphone, and/or web-based apps), have been tested. Experimental studies have shown cardiac telerehabilitation to be effective and cost-effective, but there is inadequate evidence about how to translate this research into routine clinical practice.ObjectiveThis systematic review aimed to synthesize research evaluating the effectiveness of implementing cardiac telerehabilitation interventions at scale in routine clinical practice, including factors underlying successful implementation processes, and experimental research evaluating implementation-related outcomes.MethodsMEDLINE, Embase, PsycINFO, and Global Health databases were searched from 1990 through November 9, 2018, for studies evaluating the implementation of telerehabilitation for the self-management of CHD. Reference lists of included studies and relevant systematic reviews were hand searched to identify additional studies. Implementation outcomes of interest included acceptability, appropriateness, adoption, feasibility, fidelity, implementation cost, penetration, and sustainability. A narrative synthesis of results was carried out.ResultsNo included studies evaluated the implementation of cardiac telerehabilitation in routine clinical practice. A total of 10 studies of 2250 participants evaluated implementation outcomes, including acceptability (8/10, 80%), appropriateness (9/10, 90%), adoption (6/10, 60%), feasibility (6/10, 60%), fidelity (7/10, 70%), and implementation cost (4/10, 40%), predominantly from the participant perspective. Cardiac telerehabilitation interventions had high acceptance among the majority of participants, but technical challenges such as reliable broadband internet connectivity can impact acceptability and feasibility. Many participants considered telerehabilitation to be an appropriate alternative CR delivery model, as it was convenient, flexible, and easy to access. Participants valued interactive intervention components, such as real-time exercise monitoring and feedback as well as individualized support. The penetration and sustainability of cardiac telerehabilitation, as well as the perspectives of CR practitioners and health care organizations, have received little attention in existing cardiac telerehabilitation research.ConclusionsExperimental trials suggest that participants perceive cardiac telerehabilitation to be an acceptable and appropriate approach to improve the reach and utilization of CR, but pragmatic implementation studies are needed to understand how interventions can be sustainably translated from research into clinical practice. Addressing this gap could help realize the potential impact of telerehabilitation on CR accessibility and participation as well as person-centered, health, and economic outcomes.Trial RegistrationInternational Prospective Register of Systematic Reviews (PROSPERO) CRD42019124254; https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=124254

Cardiac Rehabilitation Services during COVID-19 Pandemic

Cardiac rehabilitation is a much appreciated but underutilized treatment strategy for cardiovascular disease. Traditional center-based cardiac rehabilitation program has been suspended due to the concrete measures adopted to flatten the COVID-19 pandemic curve. The current situation of emphasis the need of alternative approach for cardiac rehabilitation. This review shed light on consequences of COVID-19 disease on cardiac rehabilitation, the alternative approaches of cardiac rehabilitation, its potential advantages, and limitations as well as future directions.

Factors Predicting the Utilization of Center-Based Cardiac Rehabilitation Program.

Although cardiac rehabilitation (CR) is clearly beneficial to improving patients’ physical functioning and reducing heart disease progression, significant proportions of patients do not complete CR programs. To evaluate the prevalence and predictors of completion of a center-based CR program in eligible cardiac patients, existing data collected from electronic medical records were used. To identify the predictors of CR completion, we used principal components analysis (PCA) and an artificial neural network (ANN) module. Among 685 patients, 61.4% (n = 421) completed the program, 31.7% (n = 217) dropped out, and 6.9% (n = 47) were referred but failed to initiate the program. PCA was conducted to consolidate baseline data into three factors—(1) psychosocial factors (depression, anxiety, and quality of life), (2) age, and (3) BMI, which explained 66.8% of the total variance. The ANN model produced similar results as the PCA. Patients who completed CR sessions had greater extremity strength and flexibility, longer six-minute walk distance, more CR knowledge, and a better quality of life. The present study demonstrated that patients who were older, obese, and who had depression, anxiety, or a low quality of life were less likely to complete the CR program.

Home-Based Cardiac Rehabilitation: A Scientific Statement From the American Association of Cardiovascular and Pulmonary Rehabilitation, the American Heart Association, and the American College of Cardiology.

Cardiac rehabilitation (CR) is an evidence-based intervention that uses patient education, health behavior modification, and exercise training to improve secondary prevention outcomes in patients with cardiovascular disease. CR programs reduce morbidity and mortality rates in adults with ischemic heart disease, heart failure, or cardiac surgery but are significantly underused, with only a minority of eligible patients participating in CR in the United States. New delivery strategies are urgently needed to improve participation. One potential strategy is home-based CR (HBCR). In contrast to center-based CR services, which are provided in a medically supervised facility, HBCR relies on remote coaching with indirect exercise supervision and is provided mostly or entirely outside of the traditional center-based setting. Although HBCR has been successfully deployed in the United Kingdom, Canada, and other countries, most US healthcare organizations have little to no experience with such programs. The purpose of this scientific statement is to identify the core components, efficacy, strengths, limitations, evidence gaps, and research necessary to guide the future delivery of HBCR in the United States. Previous randomized trials have generated low- to moderate-strength evidence that HBCR and center-based CR can achieve similar improvements in 3- to 12-month clinical outcomes. Although HBCR appears to hold promise in expanding the use of CR to eligible patients, additional research and demonstration projects are needed to clarify, strengthen, and extend the HBCR evidence base for key subgroups, including older adults, women, underrepresented minority groups, and other higher-risk and understudied groups. In the interim, we conclude that HBCR may be a reasonable option for selected clinically stable low- to moderate-risk patients who are eligible for CR but cannot attend a traditional center-based CR program.

Comparison of Obesity Related Index and Exercise Capacity Between Center-Based and Home-Based Cardiac Rehabilitation Programs.

ObjectiveTo compare a center-based cardiac rehabilitation (CR) program with a home-based CR program in terms of improving obesity related index and cardiopulmonary exercise capacity after the completing a phase II CR program.MethodsIn this study, there were seventy-four patients with acute myocardial infarction after percutaneous coronary intervention who were analyzed. Patients with mild to moderate risk (ejection fraction >40%) were included in the group. The patients underwent an exercise tolerance test by measurement of the modified Bruce protocol at three assessment points. Those in the center-based CR group participated in a 4-week training program with electrocardiography monitoring of the patient’s progress and results, while those patients who were in the home-based CR group underwent self-exercise training. We measured the obesity related indices such as body mass index, fat free mass index (FFMI), and cardiopulmonary exercise capacity including peak oxygen consumption (VO2max), metabolic equivalents (METs), heart rate, resting systolic blood pressure and the diastolic blood pressure of the participants and noted the results.ResultsOf the 74 patients, 25 and 49 participated in the center-based and home-based CR programs, respectively. Both groups showed significant improvement in VO2max and METs at 1-month and 6-month follow-up. However, FFMI was significantly improved only in the center-based CR group after 1 month of the phase II CR.ConclusionBoth groups identified in the study showed significant improvement of VO2max and METs at 1-month and 6-month follow-up. However, there was no significant difference in the intergroup analysis. A significant improvement of FFMI was seen only in the center-based CR group after phase II CR.

2018 ACC/AHA Clinical Performance and Quality Measures for Cardiac Rehabilitation: A Report of the American College of Cardiology/American Heart Association Task Force on Performance Measures.

The American College of Cardiology (ACC)/American Heart Association (AHA) performance measurement sets serve as vehicles to accelerate translation of scientific evidence into clinical practice. Measure sets developed by the ACC/AHA are intended to provide practitioners and institutions that deliver cardiovascular services with tools to measure the quality of care provided and identify opportunities for improvement. Writing committees are instructed to consider the methodology of performance measure development1 and to ensure that the measures developed are aligned with ACC/AHA clinical guidelines.

Six-Minute Walk Test Distances in Fast-Track and Traditional Cardiac Rehabilitation: A 3-YEAR DATABASE REVIEW.

Home-based and center-based cardiac rehabilitation (CR) have demonstrated similar levels of risk factor reduction. Cardiac rehabilitation models with fewer exercise sessions may be as effective as traditional models. This study reviewed a community phase II CR database from 2007 to 2010. A fast-track CR (FTCR) group was introduced alongside an existing traditional CR (TCR) program. The 2 programs ran concurrently on different days. Both FTCR and TCR treatment groups undertook supervised low to moderate intensity exercise training for 6 weeks and were provided with home exercise advice. Fast-track CR included once-weekly exercise sessions and a 1-time 7-hour education session; TCR included twice-weekly exercise and education sessions. Similar education was provided in both programs. Six-minute walk test distance (6MWD) was assessed pre-CR and post-CR for both groups. Six hundred and twenty patients enrolled in CR during the period, and patients elected or were assigned (not randomized) to FTCR (n = 197) or to TCR (n = 423) treatment groups. Complete 6MWD data sets were available for 115 FTCR and 254 TCR subjects. Repeated-measures analysis of variance found 6MWD outcomes to be similar for both groups over both assessments combined and at each assessment point. Improvements in 6MWD post-CR were different for men and women in the CR database (8% vs 5%, respectively, P < .001). Six-minute walk test distance outcomes were not different for subjects undergoing once-weekly or twice-weekly supervised CR exercise sessions. CR models with fewer supervised exercise sessions may provide similar functional outcomes to traditional CR models.
