Comprehensiveness of cardiac rehabilitation program in Korea: a nation-wide survey result.

BACKGROUND: Cardiac rehabilitation (CR) is an essential component in secondary prevention of cardiovascular diseases. Current guidelines recommend that the program should be comprehensive including multidisciplinary behavioral intervention, not only exercise training. While the utilization of CR is gradually increasing, the comprehensiveness of the program has not been systemically evaluated in Korea. METHODS: During the year 2020, nation-wide survey was done to evaluate the current status of CR in Korea. Survey was done by web-based structured questionnaire. Survey was requested to 164 hospitals performing percutaneous coronary intervention. RESULTS: Among 164 hospitals, 47 (28.7%) hospitals had CR programs. In hospitals with CR, multidisciplinary intervention other than exercise-based program was provided only partially: nutritional counseling (63%), vocational counseling for return to work (39%), stress management (31%), psychological evaluation (18%). Personnel for CR was commonly not dedicated to the program or even absent: (percentage of dedicated, concurrent with other work, absent) physical therapist (59, 41, 0%), nurse (31, 69, 0%), dietician (6, 65, 29%), clinical psychologist (0, 37, 63%). CONCLUSION: Comprehensiveness of CR in Korea is suboptimal and human resource for it is poorly disposed. More awareness of current status by both clinicians and health policy makers is needed and insurance reimbursement for educational program should be improved.

Sex Differences in Predictors of Completion of a 6-Month Adapted Cardiac Rehabilitation Program for People With Type 2 Diabetes and No Known Cardiac Disease.

BACKGROUND: Our aim in this study was to determine sex differences and predictors of noncompletion of a comprehensive adapted cardiac rehabilitation program (CRP) for people with type 2 diabetes (no known cardiac disease). METHODS: Reasons for noncompletion of a 6-month adapted diabetes exercise-based CRP were ascertained by interview between 2006 and 2017. Regression analyses were conducted to determine demographic, cardiopulmonary, medical and psychosocial predictors of noncompletion in all participants and in females and males separately. RESULTS: Among all participants (460 females and 375 males), predictors of dropout included higher depression score, being unemployed, higher glycated hemoglobin (A1C), younger age and fewer comorbidities. There was no difference in completion rate between females and males in bivariate (28% vs 28.3%, p=0.9) or multivariate (odds ratio=1.089, 95% confidence interval 0.79 to 1.5, p=0.6) analyses, but predictors of dropout varied. In females, these predictors included being married/partnered, living with obesity and having a higher depression score, A1C and triglycerides level, independent of age. For males, only higher depression score and younger age predicted dropout. There was no difference in medical dropouts between females and males (37.2% vs 34% of all dropouts, p=0.6) or in reasons for dropout (p>0.05 for all) or attendance to prescheduled sessions in completers (69.2±16.8% vs 70.4±18.8%, p=0.5) or dropouts (24.7±15.7% vs 25.2±16.1%, p=0.8), respectively. CONCLUSIONS: There was no sex difference in noncompletion, attendance or reasons for dropout from a diabetes CRP. However, being married/partnered, living with obesity and having higher A1C and triglycerides were unique predictors of dropout for females and younger age for males. Being unemployed, glycemic control and depressive symptoms are targets for promoting completion in all participants that can be addressed by multidisciplinary CRP teams.

Nature, availability, and utilization of women-focused cardiac rehabilitation: a systematic review.

BACKGROUND: Women do not participate in cardiac rehabilitation (CR) to the same degree as men; women-focused CR may address this. This systematic review investigated the: (1) nature, (2) availability, as well as (3a) utilization of, and (b) satisfaction with women-focused CR. METHODS: Medline, Pubmed, Embase, PsycINFO, CINAHL, Web of Science, Scopus and Emcare were searched for articles from inception to May 2020. Primary studies of any design were included. Adult females with any cardiac diseases, participating in women-focused CR (i.e., program or sessions included ≥ 50% females, or was 1-1 and tailored to women's needs) were considered. Two authors rated citations for inclusion. One extracted data, including study quality rated as per the Mixed-Methods Assessment Tool (MMAT), which was checked independently by a second author. Results were analyzed in accordance with the Synthesis Without Meta-analysis (SWiM) reporting guideline. RESULTS: 3498 unique citations were identified, with 28 studies (53 papers) included (3697 women; ≥ 10 countries). Globally, women-focused CR is offered by 40.9% of countries that have CR, with 32.1% of programs in those countries offering it. Thirteen (46.4%) studies offered women-focused sessions (vs. full program), 17 (60.7%) were women-only, and 11 (39.3%) had gender-tailoring. Five (17.9%) programs offered alternate forms of exercise, and 17 (60.7%) focused on psychosocial aspects. With regard to utilization, women-focused CR cannot be offered as frequently, so could be less accessible. Adherence may be greater with gender-tailored CR, and completion effects are not known. Satisfaction was assessed in 1 trial, and results were equivocal. CONCLUSIONS: Women-focused CR involves tailoring of content, mode and/or sex composition. Availability is limited. Effects on utilization require further study.

Delivery preferences for psychological intervention in cardiac rehabilitation: a pilot discrete choice experiment.

BACKGROUND: Cardiac rehabilitation (CR) is a programme of care offered to people who recently experienced a cardiac event. There is a growing focus on home-based formats of CR and a lack of evidence on preferences for psychological care in CR. This pilot study aimed to investigate preferences for delivery attributes of a psychological therapy intervention in CR patients with symptoms of anxiety and/or depression. METHODS: A discrete choice experiment (DCE) was conducted and recruited participants from a feasibility trial. Participants were asked to choose between two hypothetical interventions, described using five attributes; intervention type (home or centre-based), information provided, therapy manual format, cost to the National Health Service (NHS) and waiting time. A separate opt-out was included. A conditional logit using maximum likelihood estimation was used to analyse preferences. The NHS cost was used to estimate willingness to pay for aspects of the intervention delivery. RESULTS: 35 responses were received (39% response rate). Results indicated that participants would prefer to receive any form of therapy compared with no therapy. Statistically significant results were limited, but included participants being keen to avoid not receiving information prior to therapy (ß=-0.270; p=0.03) and preferring a lower cost to the NHS (ß=-0.001; p=0.00). No significant results were identified for the type of psychological intervention, format of therapy/exercises and programme start time. Coefficients indicated preferences were stronger for home-based therapy compared with centre-based, but this was not significant. CONCLUSIONS: The pilot study demonstrates the feasibility of a DCE in this group, it identifies potential attributes and levels, and estimates the sample sizes needed for a full study. Preliminary evidence indicated that sampled participants tended to prefer home-based psychological therapy in CR and wanted to receive information before initiating therapy. Results are limited due to the pilot design and further research is needed.

An Aboriginal and Torres Strait Islander Cardiac Rehabilitation program delivered in a non-Indigenous health service (Yeddung Gauar): a mixed methods feasibility study.

BACKGROUND: There is limited evidence of Aboriginal and Torres Strait Islander people attending cardiac rehabilitation (CR) programs despite high levels of heart disease. One key enabler for CR attendance is a culturally safe program. This study evaluates improving access for Aboriginal and Torres Strait Islander women to attend a CR program in a non-Indigenous health service, alongside improving health workforce cultural safety. METHODS: An 18-week mixed-methods feasibility study was conducted, with weekly flexible CR sessions delivered by a multidisciplinary team and an Aboriginal and/or Torres Strait Islander Health Worker (AHW) at a university health centre. Aboriginal and Torres Strait Islander women who were at risk of, or had experienced, a cardiac event were recruited. Data was collected from participants at baseline, and at every sixth-session attended, including measures of disease risk, quality-of-life, exercise capacity and anxiety and depression. Cultural awareness training was provided for health professionals before the program commenced. Assessment of health professionals' cultural awareness pre- and post-program was evaluated using a questionnaire (n = 18). Qualitative data from participants (n = 3), the AHW, health professionals (n = 4) and referrers (n = 4) was collected at the end of the program using yarning methodology and analysed thematically using Charmaz's constant comparative approach. RESULTS: Eight referrals were received for the CR program and four Aboriginal women attended the program, aged from 24 to 68 years. Adherence to the weekly sessions ranged from 65 to 100%. At the program's conclusion, there was a significant change in health professionals' perception of social policies implemented to 'improve' Aboriginal people, and self-reported changes in health professionals' behaviours and skills. Themes were identified for recruitment, participants, health professionals and program delivery, with cultural safety enveloping all areas. Trust was a major theme for recruitment and adherence of participants. The AHW was a key enabler of cultural authenticity, and the flexibility of the program contributed greatly to participant perceptions of cultural safety. Barriers for attendance were not unique to this population. CONCLUSION: The flexible CR program in a non-Indigenous service provided a culturally safe environment for Aboriginal women but referrals were low. Importantly, the combination of cultural awareness training and participation in the program delivery improved health professionals' confidence in working with Aboriginal people.

Women-Only Cardiac Rehabilitation Delivery Around the World.

BACKGROUND: Women utilise cardiac rehabilitation (CR) significantly less than men. Gender-tailored CR improves adherence and mental health outcomes when compared to traditional programs. This study ascertained the availability of women-only (W-O) CR classes globally. METHODS: In this cross-sectional study, an online survey was administered to CR programs globally, assessing delivery of W-O classes, among other program characteristics. Univariate tests were performed to compare provision of W-O CR by program characteristics. RESULTS: Data were collected in 93/111 countries with CR (83.8% country response rate); 1,082 surveys (32.1% program response rate) were initiated. Globally, 38 (40.9%; range 1.2-100% of programs/country) countries and 110 (11.8%) programs offered W-O CR. Women-Only CR was offered in 55 (7.4%) programs in high-income countries, versus 55 (16.4%) programs in low- and middle-income countries (p<0.001); it was offered most commonly in the Eastern Mediterranean region (n=5, 55.6%; p=0.22). Programs that offered W-O CR were more often located in an academic or tertiary facility, served more patients/year, offered more components, treated more patients/session, offered alternative forms of exercise, had more staff (including cardiologists, dietitians, and administrative assistants, but not mental health care professionals), and perceived space and human resources to be less of a barrier to delivery than programs not offering W-O CR (all p<0.05). CONCLUSION: Women-Only CR was not commonly offered. Only larger, well-resourced programs seem to have the capacity to offer it, so expanding delivery may require exploiting low-cost, less human resource-intensive approaches such as online peer support.

Cardiac Rehabilitation Programs for Chronic Heart Disease: A Bayesian Network Meta-analysis.

BACKGROUND: Cardiac rehabilitation is a medically supervised program after coronary events that involves exercise and dietary modification. We evaluated the comparative benefits and harms of cardiac rehabilitation strategies via a network meta-analysis. METHODS: We followed a pre-specified protocol (PROSPERO: CRD42018094998). We searched Embase, MEDLINE, and Cochrane Central Register of Randomized Trials databases for randomized controlled trials that evaluated cardiac rehabilitation vs a second form of rehabilitation or standard/usual care in adults after myocardial infarction, coronary artery bypass grafting, percutaneous coronary intervention, or angiography. Risk of bias and evidence quality was evaluated using the Cochrane tool and Grading of Recommendations Assessment, Development and Evaluation (GRADE), respectively. Pairwise and Bayesian network meta-analyses were performed for 11 clinical outcomes. RESULTS: We included 134 randomized controlled trials involving 62,322 participants. Compared with standard care, exercise-only cardiac rehabilitation reduced the odds of cardiovascular mortality (odds ratio [OR], 0.70; 95% credibility interval [CrI], 0.51-0.96; moderate-quality evidence), major adverse cardiovascular events (OR, 0.57; 95% CrI, 0.40-0.78; low-quality evidence), nonfatal myocardial infarction (OR, 0.71; 95% CrI, 0.54-0.93; moderate-quality evidence), all-cause hospitalization (OR, 0.74; 95% CrI, 0.54-0.98; moderate-quality evidence), and cardiovascular hospitalization (OR, 0.69; 95% CrI, 0.51-0.88; moderate-quality evidence). Exercise-only cardiac rehabilitation was associated with lower cardiovascular hospitalization risk relative to cardiac rehabilitation without exercise (OR, 0.68; 95% CrI, 0.48-0.97; moderate-quality evidence). CONCLUSIONS: Cardiac rehabilitation programs containing exercise might provide broader cardiovascular benefits compared with those without exercise.

Factors related to fear of movement after acute cardiac hospitalization.

BACKGROUND: Fear of movement (kinesiophobia) after an acute cardiac hospitalization (ACH) is associated with reduced physical activity (PA) and non-adherence to cardiac rehabilitation (CR). PURPOSE: To investigate which factors are related to kinesiophobia after an ACH, and to investigate the support needs of patients in relation to PA and the uptake of CR. METHODS: Patients were included 2-3 weeks after hospital discharge for ACH. The level of kinesiophobia was assessed with the Tampa Scale for Kinesiophobia (TSK-NL Heart). A score of > 28 points is defined as 'high levels of kinesiophobia' (HighKin) and ≤ 28 as 'low levels of kinesiophobia' (LowKin). Patients were invited to participate in a semi-structured interview with the fear avoidance model (FAM) as theoretical framework. Interviews continued until data-saturation was reached. All interviews were analyzed with an inductive content analysis. RESULTS: Data-saturation was reached after 16 participants (median age 65) were included in this study after an ACH. HighKin were diagnosed in seven patients. HighKin were related to: (1) disrupted healthcare process, (2) negative beliefs and attitudes concerning PA. LowKin were related to: (1) understanding the necessity of PA, (2) experiencing social support. Patients formulated 'tailored information and support from a health care provider' as most important need after hospital discharge. CONCLUSION: This study adds to the knowledge of factors related to kinesiophobia and its influence on PA and the uptake of CR. These findings should be further validated in future studies and can be used to develop early interventions to prevent or treat kinesiophobia and stimulate the uptake of CR.

Transition to Home-Based Treatment Plans for Center-Based Cardiac, Pulmonary, and Vascular Rehabilitation during COVID-19.

BACKGROUND: Traditional rehabilitation services, whether they are cardiac, pulmonary, or vascular, consist of 6-36 center-based, supervised sessions; however, due to COVID-19, in-person visits were suspended. This study sought to implement a transitional home-based treatment plan (HBTP) to patients. METHOD: Patients enrolled in a rehabilitation service at the Miriam Hospital during the time of temporary closure were provided with a HBTP that was individualized to their needs and multi-disciplinary in nature. Patients were called weekly for continual guidance and support. RESULTS: Of the 129 patients that received a HBTP, 115 (89%) participated in follow-up correspondence (63±12 years, 83% white, 66% male, 81% enrolled in cardiac rehab). Nearly 70% of patients continued to participate in regular exercise and upon re-opening, 69 (60%) of patients returned to center-based care. Psychosocial factors appeared to inhibit treatment adherence. CONCLUSIONS: Patients are receptive to an HBTP and subsequent follow-up throughout temporary closure of rehabilitation services.

Response to Exercise Training During Cardiac Rehabilitation Differs by Sex.

PURPOSE: Directly measured peak aerobic capacity or oxygen uptake is a powerful predictor of prognosis in individuals with cardiovascular disease. Women enter phase 2 cardiac rehabilitation (CR) with lower and their response to training, compared with men, is equivocal. We analyzed at entry and exit in patients participating in CR and improvements by diagnosis to assess training response. We also identified sex differences that may influence change in . METHODS: The cohort included consecutive patients enrolled in CR between January 1996 and December 2015 who performed entry exercise tolerance tests. Data collected included demographics, index diagnosis, , and exercise training response. RESULTS: The cohort consisted of 3925 patients (24% female). There was a significant interaction between baseline and diagnosis (P < .001), with percutaneous coronary intervention and myocardial infarction greater than other diagnoses. Surgical patients demonstrated greater improvement in than nonsurgical diagnoses (n = 1789; P < .001). Women had lower than men for all diagnoses (P < .02) and demonstrated less improvement (13 vs 17%, P < .001). Percent improvement using estimated metabolic equivalents of task (METs) were similar for women and men (33 vs 31%, P = NS). Despite overall increases in , 18% of patients (24% women, 16% men) failed to demonstrate any improvement (exit ≤ entry ). CONCLUSIONS: While there were no differences in training effect estimated by METs, directly measured showed a significantly lower training response for women despite adjusting for covariates. In addition, 18% of patients did not see any improvement in . Alternatives to traditional CR exercise programming need to be considered.

Validity of the Talk Test as a Method to Estimate Ventilatory Threshold and Guide Exercise Intensity in Cardiac Patients.

PURPOSE: To determine the relationship between the Talk Test (TT) and ventilatory threshold (VT) in patients with cardiac disease and to compare the TT with exercise intensity guidelines. METHODS: Twenty cardiac patients, aged 65 ± 8.5 yr, performed 2 exercise tests with identical ramp protocols on a cycle ergometer on the same day. One test was a submaximal effort to assess exercise intensity using the TT. The other was a cardiopulmonary exercise test using breath-by-breath gas analysis to identify VT and cardiorespiratory fitness. RESULTS: Oxygen uptake and workload at the last positive stage (TTpos) was significantly lower than at VT. and workload at the equivocal stage (TTeq) and the first negative stage (TTneg) were not significantly different from VT, but limits of agreement (LoA) were wide. There was no significant difference in heart rate (HR) at TTpos and TTeq compared with VT, but HR at Tneg was significantly higher. The correlations between the TT and VT ranged from 0.37 to 0.60. Intensity at the different TT stages ranged from 58-77% of . All TT stages were within intensity guidelines of 40-80% of . CONCLUSION: Although no significant differences were found in and workload for TTeq and TTneg when compared with VT, LoA demonstrated wide ranges, suggesting poor individual correspondence. The different stages of the TT can be used as a practical method to guide exercise intensity in patients with cardiac disease.

Experiences With Wearable Activity Data During Self-Care by Chronic Heart Patients: Qualitative Study.

BACKGROUND: Most commercial activity trackers are developed as consumer devices and not as clinical devices. The aim is to monitor and motivate sport activities, healthy living, and similar wellness purposes, and the devices are not designed to support care management in a clinical context. There are great expectations for using wearable sensor devices in health care settings, and the separate realms of wellness tracking and disease self-monitoring are increasingly becoming blurred. However, patients' experiences with activity tracking technologies designed for use outside the clinical context have received little academic attention. OBJECTIVE: This study aimed to contribute to understanding how patients with a chronic disease experience activity data from consumer self-tracking devices related to self-care and their chronic illness. Our research question was: "How do patients with heart disease experience activity data in relation to self-care and chronic illness?" METHODS: We conducted a qualitative interview study with patients with chronic heart disease (n=27) who had an implanted cardioverter-defibrillator. Patients were invited to wear a FitBit Alta HR wearable activity tracker for 3-12 months and provide their perspectives on their experiences with step, sleep, and heart rate data. The average age was 57.2 years (25 men and 2 women), and patients used the tracker for 4-49 weeks (mean 26.1 weeks). Semistructured interviews (n=66) were conducted with patients 2-3 times and were analyzed iteratively in workshops using thematic analysis and abductive reasoning logic. RESULTS: Of the 27 patients, 18 related the heart rate, sleep, and step count data directly to their heart disease. Wearable activity trackers actualized patients' experiences across 3 dimensions with a spectrum of contrasting experiences: (1) knowing, which spanned gaining insight and evoking doubts; (2) feeling, which spanned being reassured and becoming anxious; and (3) evaluating, which spanned promoting improvements and exposing failure. CONCLUSIONS: Patients' experiences could reside more on one end of the spectrum, could reside across all 3 dimensions, or could combine contrasting positions and even move across the spectrum over time. Activity data from wearable devices may be a resource for self-care; however, the data may simultaneously constrain and create uncertainty, fear, and anxiety. By showing how patients experience self-tracking data across dimensions of knowing, feeling, and evaluating, we point toward the richness and complexity of these data experiences in the context of chronic illness and self-care.

Cardiac Rehab for Functional Improvement.

PURPOSE OF REVIEW: Cardiac Rehabilitation (CR) was originally designed to return patients to their prior level of functioning after myocardial infarction (MI). Research has since revealed the mortality benefit of CR, and CR has been given a class 1A recommendation by the American Heart Association/American College of Cardiology (AHA/ACC). In this review, we shift our focus back to function and highlight the most recent research on the functional benefits of CR in a broad range of cardiac diseases and conditions. RECENT FINDINGS: Currently, CR is indicated for patients with coronary artery disease (CAD), heart failure with reduced ejection fraction (HFrEF), peripheral arterial disease (PAD), transcatheter aortic valve replacement (TAVR), left ventricular assist devices (LVADs), and cardiac transplant. Among patients with those conditions, CR has been shown to improve exercise capacity, cognition, mental health, and overall quality of life. As survival of cardiac diseases increases, CR emerges as an increasingly important tool to lend quality to patients' lives and therefore give meaning to survival.

Cardiac Rehabilitation During Quarantine in COVID-19 Pandemic: Challenges for Center-Based Programs.

Because of the coronavirus disease 2019 (COVID-19) epidemic, many cardiac rehabilitation (CR) services and programs are stopped. Because CR is a class I level A recommendation with clinical benefits that are now well documented, the cessation of CR programs can lead to dramatic consequences in terms of public health. We propose here a viewpoint of significant interest about the sudden need to develop remote home-based CR programs both in clinical research and in clinical care routine. This last decade, the literature on remote home-based CR programs has been increasing, but to date only clinical research experiences have been implemented. Benefits are numerous and the relevance of this approach has obviously increased with the actual health emergency. The COVID-19 crisis, the important prevalence of smartphones, and high-speed Internet during confinement should be viewed as an opportunity to promote a major shift in CR programs with the use of telemedicine to advance the health of a larger number of individuals with cardiac disease.

Clinical outcomes after cardiac rehabilitation in elderly patients with and without diabetes mellitus: The EU-CaRE multicenter cohort study.

BACKGROUND: The prevalence of patients with concomitant cardiovascular disease and diabetes mellitus (DM) is increasing rapidly. We aimed to compare the effectiveness of current cardiac rehabilitation (CR) programs across seven European countries between elderly cardiac patients with and without DM. METHODS: 1633 acute and chronic coronary artery disease (CAD) patients and patients after valve intervention with an age 65 or above who participated in comprehensive CR (3 weeks to 3 months, depending on centre) were included. Peak oxygen uptake (VO2 peak), body mass index, resting systolic blood pressure, low-density lipoprotein-cholesterol (LDL-C), and glycated haemoglobin (HbA1c) were assessed before start of CR, at termination of CR (variable time point), and 12 months after start of CR, with no intervention after CR. Baseline values and changes from baseline to 12-month follow-up were compared between patients with and without DM using mixed models, and mortality and hospitalisation rates using logistic regression. RESULTS: 430 (26.3%) patients had DM. Patients with DM had more body fat, lower educational level, more comorbidities, cardiovascular risk factors, and more advanced CAD. Both groups increased their VO2 peak over the study period but with a significantly lower improvement from baseline to follow-up in patients with DM. In the DM group, change in HbA1c was associated with weight change but not with change in absolute VO2 peak. 12-month cardiac mortality was higher in patients with DM. CONCLUSIONS: While immediate improvements in VO2 peak after CR in elderly patients with and without DM were similar, 12-month maintenance of this improvement was inferior in patients with DM, possibly related to disease progression. Glycemic control was less favourable in diabetic patients needing insulin in the short- and long-term. Since glycemic control was only related to weight loss but not to increase in exercise capacity, this highlights the importance of weight loss in obese DM patients during CR.
