Factors associated with participation in cardiac rehabilitation in patients with acute myocardial infarction: A systematic review and meta-analysis.

Cardiac rehabilitation (CR) is effective in reducing morbidity and mortality in patients with acute myocardial infarction (AMI), but the participation rate is low and its influencing factors vary. Our study aimed to systematically review the literature and investigate the participation rates and influencing factors of CR in patients with AMI. We searched 10 databases, including PubMed, Web of Science, Cochrane Library, and so forth. A systematic review and meta-analysis were conducted on the studies on the factors affecting CR participation in AMI. The Q tests and the I2 tests were used to assess heterogeneity between studies. The combined effect size and odds ratio (OR) and their respective 95% confidence interval (CI) for CR participation rate and its influences are expressed, respectively. Stata 17.0 software was used for statistical analysis. We included 14 studies with 114 542 participants. Current evidence indicates a CR participation rate of 34% (95% CI: 21%-46%) in patients with AMI. The pooled OR values and CI of each influencing factor are as follows: over 60 years old (OR = 0.865; 95% CI: 0.772-0.969), male (OR = 1.690; 95% CI: 1.276-2.239), college education or above (OR = 2.526; 95% CI: 1.117-5.711), ST-segment elevation myocardial infarction (OR = 4.257; 95% CI: 2.004-9.045), decrease in left ventricular ejection fraction (OR = 0.918; 95% CI: 0.868-0.971), higher economic level (OR = 1.282; 95% CI: 1.108-1.483), history of coronary heart disease(OR = 0.667; 95% CI: 0.509-0.875), smoking (OR = 0.665; 95% CI: 0.550-0.805), combined hypertension (OR = 0.638; 95% CI: 0.562-0.723), and combined hyperlipidemia (OR = 0.577; 95% CI: 0.512-0.651). The overall participation rate of CR in AMI patients is low, and various factors affect the participation rate. Specialist medical staff are needed to further promote CR rehabilitation concepts and scientific knowledge, and take appropriate measures to address the influencing factors to increase CR utilization and improve patient prognosis.

Race or ethnicity and education in cardiac rehabilitation enrollment

BackgroundAlthough cardiac rehabilitation (CR) has established benefits for cardiovascular health, it remains significantly underutilized, with substantial differences in participation related to factors such as educational attainment (EA), race, and ethnicity. We studied a geographically and racially diverse cohort of insured individuals in a health claims database to (1) evaluate differences in CR participation by EA and race or ethnicity and (2) assess how EA modifies associations between race or ethnicity and CR participation. MethodsWe conducted a retrospective cohort study of individuals identified in Optum's de-identified Clinformatics® database between 1/1/2016 and 12/31/2019. Eligible individuals included those aged ≥18 years with a hospitalization for an incident CR-qualifying diagnosis. We calculated incidence rates of CR enrollment by EA and race or ethnicity, as well as associations of EA and race or ethnicity with CR enrollment, and evaluated interaction between EA and race or ethnicity with respect to CR participation. ResultsWe identified 171,297 individuals eligible for CR with a mean ± SD age of 70.4 ± 11.6 years; 37.4 % were female, and 68.3 % had >high school education. We observed a dose-response association between EA and rate of participation in CR. After adjustment, compared to White individuals, the odds of attending CR was 24 % lower for Asian individuals [95 % confidence interval (CI): 17 %, 30 %], 13 % lower for Black individuals (95 % CI: 9 %, 17 %), and 32 % lower for Hispanic individuals (95 % CI: 28 %, 35 %), all p < 0.0001. However, Black individuals with ≥bachelor's degree had a similar odds of CR enrollment as White individuals with ≥bachelor's degree (odds ratio 1.01, 95 % CI: 0.85, 1.20, p = 0.95). ConclusionsEA was positively associated with CR enrollment across racial and ethnic groups. Higher EA might partially attenuate racial and ethnic differences in CR participation, but significant disparities persist. Our findings support increased attention to individuals with limited education to improve CR enrollment.

Understanding cardiac rehabilitation delivery in Scotland during the COVID-19 pandemic: lessons for the future

Background/Aims Cardiac rehabilitation services were disrupted during the early stages of the COVID-19 pandemic because of limitations on interpersonal contact, exercise facility closures and clinical service reorganisation. This necessitated urgent service redesign. The authors aimed to understand the changes to cardiac rehabilitation service delivery in Scotland, the impacts on staff and participant experiences, and implications for future delivery. Methods A concurrent mixed-methods study was conducted between April and December 2021. A quantitative online survey compared service provision before the pandemic (21 March 2019 to 20 November 2019) with provision after the onset of the pandemic (21 March 2020–20 November 2020). Quantitative data were analysed descriptively. Semi-structured telephone interviews were conducted with cardiac rehabilitation professionals and participants. These qualitative data were thematically analysed using the framework approach. Results Representatives (n=11) from 11 services completed the survey, while 11 staff and 17 patients completed the interviews. Services reported staffing reductions, delayed initial patient contact, replacement of face-to-face rehabilitation with telephone and online support, compromised initial assessments and reduced exit assessments. Patients relied more heavily on cardiac rehabilitation staff as a result of reduced access to other health professionals, and experienced issues with continuity of care. Technology presented remote service opportunities, but challenges around poor access to systems and technological literacy issues created barriers to service delivery. Service evaluation data were inaccessible. Conclusions Scottish cardiac rehabilitation services were adversely impacted by the COVID-19 pandemic and responded by developing remote options. These can be enhanced by screening patients to assess their access to technology and identify any literacy issues, as well as developing online educational videos and downloadable resources. Staff education is needed to encourage use of technology, including exercise monitoring via wearables. A national audit is required to assess delivery and outcomes.

Sex differences in cardiac rehabilitation barriers among non-enrollees in the context of lower gender equality: a cross-sectional study

BackgroundDespite the benefits of cardiac rehabilitation (CR), it remains under-utilized, particularly by women. This study compared CR barriers between non-enrolling men and women in Iran, which has among the lowest gender equality globally.MethodsIn this cross-sectional study, CR barriers were assessed via phone interview in phase II non-attenders from March 2017 to February 2018 with the Persian version of the Cardiac Rehabilitation Barriers Scale (CRBS-P). T-tests were used to compare scores, with each of 18 barriers scored out of 5, between men and women.Results357 (33.9%) of the sample of 1053 were women, and they were older, less educated and less often employed than men. Total mean CRBS scores were significantly greater in women (2.37 ± 0.37) than men (2.29 ± 0.35; effect size[ES] = 0.08, confidence interval[CI]: 0.03–0.13; p < 0.001). The top CR barriers among women were cost (3.35; ES = 0.40, CI:0.23–0.56; P < 0.001), transportation problems (3.24; ES = 0.41, CI:0.25–0.58; P < 0.001), distance (3.21; ES = 0.31, CI:0.15–0.48; P < 0.001), comorbidities (2.97; ES = 0.49, CI:0.34–0.64; P < 0.001), low energy (2.41; ES = 0.29, CI:0.18–0.41; P < 0.001), finding exercise as tiring or painful (2.22; ES = 0.11, CI:0.02–0.21; P = 0.018), and older age (2.27; ES = 0.18, CI:0.07–0.28; P = 0.001). Men rated “already exercise at home or in community” (2.69; ES = 0.23, CI:0.1–0.36; P = 0.001), time constraints (2.18; ES = 0.15, CI:0.07–0.23; P < 0.001) and work responsibilities (2.24; ES = 0.16, CI:0.07–0.25; P = 0.001) as greater CR barriers than women.ConclusionWomen had greater barriers to CR participation than men. CR programs should be modified to address women’s needs. Home-based CR tailored to women’s exercise needs and preferences should be considered.

Cardiac rehabilitation participation and risk of falls in older individuals with cardiovascular disease

Abstract Funding Acknowledgements Type of funding sources: None. Background Falls are the leading cause of injury-related morbidity and mortality among older adults in the United States, including those with cardiovascular disease. Cardiac rehabilitation (CR) helps to optimize functional capacity, strength, and balance in patients with cardiovascular disease and, in theory, may reduce the risk of falls. However, little evidence has been published in this regard. Purpose The purpose of this study was to assess the association between CR participation and risk of falls in a community-based sample of individuals 65 years of age and older with cardiovascular disease who were eligible for CR participation. Methods Individuals from Southeastern MN and Western WI, USA, 65 years of age and older who had experienced a cardiovascular event that qualified them for CR (MI, PCI, CABG, Valve Surgery, Transplant) between January 1, 2000, and December 31, 2018, were included in this study. Participation in CR (≥1 sessions, CR-group) and subsequent falls (moderate or severe, using the Campbell classification system) were ascertained using the Rochester Epidemiology Project records-linkage system. Logistic model to create propensity weighting were used to test the association between CR participation and falls after adjustment for potentially confounding factors. Results A total of 5004 individuals met inclusion criteria for the study, with 2183 (44%) included in the CR group and 2821 (56%) in the non-CR group (CR was indicated, but the individual did not participate). Overall, 1122 patients experienced a fall within the first 5 years (16% of those in the CR-group, 23% of those in the non-CR group). After adjustment, CR participation was not associated with falls, but older individuals, females, and those with a history of falls were more likely to have had a fall, compared to young individuals, males, and those without a history of a fall. Conclusions While CR is beneficial for patients with cardiovascular disease, our study did not find evidence of an association between CR participation and fall risk in individuals 65 years of age and older who have cardiovascular disease. Additional research is needed to evaluate the role of CR components that may potentially reduce modifiable risk factors for falls and thereby reduce the risk of falls.

Effect of cardiac telerehabilitation as standard care on quality of life

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – EU funding. Main funding source(s): EIT Health education grant. Background Cardiac telerehabilitation (CTR) is a continuously developing cardiac rehabilitation (CR) format that might offer a solution to some of the challenges centre-based CR programs face. CR centres continue to face suboptimal participation in their provided CR program. The COVID-19 pandemic encouraged CR centres to implement their own CTR program to tackle practical challenges and to improve participation in CR. Multiple centres have since then developed a CTR program in accordance to (inter)national guidelines. CTR aims to improve the quality of life of patients, therefore analyses of quality of life is essential. Purpose Our study aims to analyse quality of life changes over a period of three months after program initiation for patients choosing to participate in either centre-based CR or CTR. Methods Our study included (N)STEMI patients eligible for CR between November 2021 and November 2022. Patients were invited by the cardiac rehabilitation nurse during intake to participate in CR. Patients were offered the choice between centre-based CR and CTR. The centre-based CR exercise program typically lasted for 6-8 weeks and the CTR program for a total of 48 weeks. CTR offers remote-access, digital platform for patients to interact with their healthcare professionals. The digital platform monitors physical activity and progress, which can be access by both patients and coaches. Coaches provide remote-access feedback. The SF-36 questionnaire was send out right after the CR intake procedure (T0) and three months after the CR intake procedure (T1). We only analysed data from participants who completed both T0 and T1 questionnaires, using the paired sample T-test for both CTR and centre-based CR. Results Until now, 173 patients have been included in the study of which 42 patients (24%) participated in CTR. 143 patients reached T1. 84 (59%) participants completed both T0 and T1 questionnaires, of which 24 (29%) participate in CTR (92% male, mean age 60) and 60 (71%) participate in centre-based CR (80% male, mean age 64). Participants from the centre-based CR program improved on both physical (score: +11,12; p &amp;lt; 0,001) and emotional (score: +9,30; p = 0,028) role functioning over a three month period. Participants in the CTR program improved on physical role functioning (score: +18,75; p = 0,002) and social functioning (score: + 13,54; p = 0,019). Conclusion Our preliminary show that patients were able to improve quality of life in both CTR and centre-based CR. Therefore, CTR can be used as an alternative to centre-based CR as standard care. Future research should focus on long term effects on quality of life.

Gender disparities in Cardiac Rehabilitation - Are we concealing apples from Eve?

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Cardiovascular disease is a leading cause of death in both men and women and cardiac rehabilitation (CR) is recommended as part of secondary prevention for these patients. Despite this, there are still important asymmetries when it comes to enrolment of women in CR programs. Purpose To determine differences between referral and outcomes of cardiac rehabilitation programs among women. Methods Prospective cohort study which included consecutive pts who were participating in a centre-based CR program lasting 8 weeks from 2019 to 2021. We analyzed prevalence of risk factors, lab echocardiographic and CPET data in women who were enrolled in the program. Statistical analysis was performed with Mann-Whitney and Wilcoxon tests Results: From a total of 349 patients, 60 women completed a CR program – 17,8% of pts – representing a far smaller percentage when accounting to acute coronary syndrome events in our center in those 2 years (31% women). Mean age of female participants was 60 ± 11,8 years; 74% had hypertension, 64% dyslipidemia, 19% diabetes and only 40% had never smoked. There were no significant differences when compared to male, except for thyroid disease which was more frequent among women (p&amp;lt;0.01). Regarding lab data we noticed an improvement of LDL-c, total cholesterol, HDL-c, although only NTproBNP showed a statistically significant reduction (p=0.001). There was also an improvement of LVEF, once again without statistical significance (in contrast to the male population). After completion of the program, there was an improvement regarding CPET duration and workload (p&amp;lt;0.001 and p=0.019). Interestingly there was no difference in terms of peak VO2/kg, a data that goes in line with some reports of less impact of exercise based CR in this parameter in women. Moreover, there were no differences between genders in terms of outcome, namely admissions or cardiovascular death. Conclusion Women still have a lower rate of enrolment in CR programs, despite results showing a similar benefit to men. CR effectiveness by CPET should include other parameters besides VO2 peak. Strategies should be developed to improve women participation in CR.

Effect of hybrid cardiac rehabilitation using a smart device: a randomized controlled trial

Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – National budget only. Main funding source(s): Korea National Institute of Health. Background Although cardiac rehabilitation (CR) has been proven to be effective in secondary prevention for patients with cardiovascular diseases, the actual participation in CR is still unsatisfactory. Because home-based CR provides better access to patients and is as effective as center-based CR, it is considered a promising alternative that can overcome various barriers impeding CR implementation. However, home-based CR has not garnered enough attention due to a lack of proper communication, concerns about unexpected adverse events caused by non-monitored exercises, and the absence of supporting insurance services. Purpose We utilized a smart ring with a photoplethysmography to monitor heart rate. Recorded data were stored on a website where the researchers could remotely access and check the uploaded measurements. This study aims to identify the clinical effects of hybrid CR by weekly telephone counseling based on the patients' actual physical activities obtained from the device. Methods Cardiovascular disease patients were educated on concrete methods of home-based CR, including the type, intensity, and time of exercise as well as precautions. They were also instructed to wear the device during exercise. The patients were randomly enrolled into two groups: intervention and observation groups. The patients of the intervention group were given weekly telephone counseling and encouraged to maintain optimal physical activities. In the observational group, only exercise data were recorded without additional interventions. Before and after three months of training, the results of the symptom-limited cardiopulmonary exercise test between the two groups were compared. Results A total of sixty-four patients were enrolled (thirty-two in each group). The subjects were 59.8 ± 9.0 years old and fifty-three (82.8%) were male. There were no significant differences in diagnosis and results of baseline symptom-limited cardiopulmonary exercise test between the two groups (Table 1). After three months of training, peak oxygen consumption was significantly improved in both groups. However, the improvement was greater in the intervention group compared to the observation group (Table 2). Conclusion Home-based CR using a smart device was effective in improving oxygen consumption. For greater effectiveness, proper monitoring and timely counseling by medical experts are likely to be necessary.

Temporal trends in cardiac rehabilitation participation and its core components: a nationwide study from the Netherlands

Abstract Funding Acknowledgements Type of funding sources: None. Background Cardiac rehabilitation (CR) is an important secondary prevention strategy for individuals with cardiovascular diseases (CVD)(1). Nevertheless, CR participation rates remain low(2). In the past decade, more attention has been given to CR referral and participation following the development and implementation of (inter)national multidisciplinary CR guidelines(1). Purpose To assess time trends in Dutch CR participation rates between 2013-2019, as well as its distinct components (e.g., admission session, exercise training, nutrition counselling, and psychological help). Methods CVD patients with a clinical indication for CR were enrolled in this observational study. Health insurance claim data was used to identify CR participation and its components. Temporal trends were analysed using logistic restricted cubic spline regression. Results 106,212 CVD patients were included, of which 38,954 patients (37%) participated in CR. Participation rates significantly increased from 28% in 2013 to 41% in 2016 but stabilized thereafter. The time trends of participation to CR were mostly similar across different subgroups of age, (Figure 1A), sex (Figure 1B), CVD diagnosis (Figure 1C), and cardiothoracic surgery/procedure (Figure 1D). Participation rates were the highest in younger patients (&amp;lt;50 years; 52%, and 50-65 years; 50%), men (48%), patients with an ST-segment elevation myocardial infarction (73%), and coronary artery bypass grafting (82%). In contrast, participation rates were the lowest in older patients (≥85 years; 8%), women (30%) and in patients with heart failure (11%). Most CR participants received an admission session (97%) and exercise training (82%) during their CR program, whereas nutrition counselling (14%) and psychological help (10%) were underutilized (Figure 2). Conclusion CR participation rates increased, but stabilized after 2016. Age, sex, CVD diagnosis and cardiothoracic surgery/procedures affected CR participation rates. Future research and renewed implementation strategies are needed to increase CR referrals, enrolment and participation in specific CVD subgroups and to enhance its potential effectiveness by a higher utilization of modules related to dietary and psychosocial counselling.

Feasibility of a Virtual Educational Programme for Behaviour Change in Cardiac Patients from a Low-Resource Setting.

Patient education is an integral part of recovery from a critical cardiac life event and a core component of cardiac rehabilitation (CR) programmes. This study addressed the feasibility of a virtual educational programme for behaviour change in CR patients from a low-resource setting in Brazil. Cardiac patients from a CR programme closed due to the pandemic received a 12-week virtual educational intervention (WhatsApp messages and bi-weekly calls from healthcare providers). Acceptability, demand, implementation, practicality, and limited efficacy were tested. Overall, 34 patients and 8 healthcare providers agreed to participate. The intervention was considered practical and acceptable by the participants, who reported a satisfaction median of 9.0 (7.4-10.0)/10 (patients) and 9.8 (9.6-10.0)/10 (providers). The main difficulties in carrying out the intervention activities were related to technology, motivation to self-learning, and a lack of in-person orientation. All the patients reported that the information included in the intervention was aligned with their information needs. The intervention was associated with changes in exercise self-efficacy, sleep quality, depressive symptoms, and performance of high-intensity physical activity. In conclusion, the intervention was considered feasible to educate cardiac patients from a low-resource setting. It should be replicated and expanded to support patients that face barriers to onsite CR participation. Challenges related to technology and self-learning should be addressed.

The Association Between Mobile App Use and Change in Functional Capacity Among Cardiac Rehabilitation Participants: Cohort Study.

Cardiac rehabilitation (CR) is underused in the United States and globally, with participation disparities across gender, socioeconomic status, race, and ethnicities. The pandemic led to greater adoption of telehealth CR and mobile app use. Our primary objective was to estimate the association between CR mobile app use and change in functional capacity from enrollment to completion in patients participating in a CR program that offered in-person, hybrid, and telehealth CR. Our secondary objectives were to study the association between mobile app use and changes in blood pressure (BP) or program completion. We conducted a retrospective cohort study of participants enrolled in CR at an urban CR program in the United States. Participants were English speaking, at least 18 years of age, participated in the program between May 22, 2020, and May 21, 2022, and downloaded the CR mobile app. Mobile app use was quantified by number of exercise logs, vitals logs, and education material views. The primary outcome was change in functional capacity, measured by change in 6-minute walk distance (6MWD) from enrollment to completion. The secondary outcome was change in BP from enrollment to completion. We estimated associations using multivariable linear or logistic regression models adjusted for age, sex, race, ethnicity, socioeconomic status by ZIP code, insurance, and primary diagnosis for CR referral. A total of 107 participants (mean age 62.9, SD 13.02 years; 90/107, 84.1% male; and 57/105, 53.3% self-declared as White Caucasian) used the mobile app and completed the CR program. Participants had a mean 64.0 (SD 54.1) meter increase in 6MWD between enrollment and completion (P<.001). From enrollment to completion, participants with an elevated BP at baseline (≥130/80 mmHg) experienced a significant decrease in BP (systolic BP -11.5 mmHg; P=.002 and diastolic BP -7.7 mmHg; P=.003). We found no significant association between total app interactions and change in 6MWD (coefficient -0.03, 95% CI -0.1 to 0.07; P=.59) or change in BP (systolic coefficient 0.002, 95% CI -0.03 to 0.03; P=.87 and diastolic coefficient -0.005, 95% CI -0.03 to 0.02; P=.65). There was no significant association between total exercise logs and change in 6MWD (coefficient 0.1, 95% CI -0.3 to 0.4; P=.57) or total BP logs and change in BP (systolic coefficient -0.02, 95% CI -0.1 to 0.06; P=.63 and diastolic coefficient -0.02, 95% CI -0.09 to 0.04; P=.50). There was no significant association between total app interactions and completion of CR (adjusted odds ratio 1.00, 95% CI 0.99-1.01; P=.44). CR mobile app use as part of an in-person, hybrid, or telehealth CR program was not associated with greater improvement in functional capacity or BP or with program completion.

The Feasibility and Effects of Smartphone-Based Application on Cardiac Rehabilitation for Patients After Percutaneous Coronary Intervention: A Randomized Controlled Trial.

Cardiac rehabilitation (CR) referral and participation are generally found to be underused worldwide. The data in Asian regions suggest significant underutilization compared with western countries. To promote the continuity and effects of CR, this study aimed at supporting self-care and improving CR effects in phase II CR with mobile health application for Macao patients who have undergone percutaneous coronary intervention. The study was a randomized controlled trial conducted between January 2018 and June 2020 in a nongovernmental Hospital. Social cognitive theory was applied in the intervention for an experimental group. Measurements including anxiety and depression level, medication adherence, exercise capacity, physical activity level, cardiovascular risk modification, self-efficacy, quality of life, use of healthcare resources, mHealth CR utility, and satisfaction were analyzed. One hundred forty eligible patients were recruited, and 110 patients completed the study. Significant interventional effects of the experimental group were found on the reduction of total cholesterol, low-density lipoprotein, sitting time, anxiety level, and total anxiety and depression level ( P < .05). In addition, significant improvement on the 6-minute walk test, regular exercise performance, self-efficacy of cardiac exercise and diet, and quality of life were found as interventional effects in the experimental group ( P < .05). The feasibility of intervention was achieved in a satisfactory level. This theoretically grounded mobile health CR study was a unique program tailor-made to meet the care needs of patients post percutaneous coronary intervention. It was feasible and effective to support CR effects and adherence and would inform further design of clinical practice and public policies.

Hospital-Level Variation in Cardiac Rehabilitation After Myocardial Infarction in Japan During Fiscal Years 2014-2015 Using the National Database.

Background: Cardiac rehabilitation (CR) is an evidence-based medical service for patients with acute myocardial infarction (AMI); however, its implementation is inadequate. We investigated the provision status and equality of CR by hospitals in Japan using a comprehensive nationwide claims database. Methods and Results: We analyzed data from the National Database of Health Insurance Claims and Specific Health Checkups in Japan for the period April 2014-March 2016. We identified patients aged ≥20 years with postintervention AMI. We calculated hospital-level proportions of inpatient and outpatient CR participation. The equality of hospital-level proportions of inpatient and outpatient CR participation was evaluated using the Gini coefficient. We included 35,298 patients from 813 hospitals for the analysis of inpatients and 33,328 patients from 799 hospitals for the analysis of outpatients. The median hospital-level proportions of inpatient and outpatient CR participation were 73.3% and 1.8%, respectively. The distribution of inpatient CR participation was bimodal; the Gini coefficients of inpatient and outpatient CR participation were 0.37 and 0.73, respectively. Although there were statistically significant differences in the hospital-level proportion of CR participation for several hospital factors, CR certification status for reimbursement was the only visually evident factor affecting the distribution of CR participation. Conclusions: The distributions of inpatient and outpatient CR participation by hospitals were suboptimal. Further research is warranted to determine future strategies.

Socioeconomic Inequalities and Predictors of Cardiac Rehabilitation Referral: Real World Evidence.

To identify factors associated with CR referral following an acute coronary syndrome (ACS) at a university hospital. We analyzed 2,814 hospitalizations due to ACS between 2017 and 2019 in Centro Hospitalar São João. The hospital's morbidity database was used to retrieve patient information. CR referral and participation was identified from administrative databases and clinical records. Socioeconomic data was obtained from municipality of residence-level data rather than patient-specific data. Of 2,814 hospitalizations, 72% (2,028 cases) were eligible for CR. Mean age was 65.2 ± 13.4; 72% men, 33% diabetic, 57.1% hypertensive and 63.6% dyslipidemic. CR referral rate was low, at 18.8%, with 42 (11.0%) not attending CR and 39 (10.2%) dropping out. Females (odds ratio (OR): 0.72 (95% CI: 0.52-1.00), older patients (OR: 0.57 (0.42-0.77)); 55-64 years vs <55 years) and those coming from lower income municipalities (OR: 0.53 (0.41-0.69)), below median vs above median) with lower education level (OR: 0.70 (0.54-0,92); ≤ 4 years vs >4 years) were less likely to be referred to CR. There is a need for new strategies to promote CR in disadvantaged groups, as gender, age, and socioeconomic inequities in access to CR remain unresolved.

Translation, Cross-Cultural Adaptation and Psychometric Validation of the Arabic Version of the Cardiac Rehabilitation Barriers Scale (CRBS-A) with Strategies to Mitigate Barriers.

Cardiac rehabilitation (CR) utilization is low, particularly in Arabic-speaking countries. This study aimed to translate and psychometrically validate the CR Barriers Scale in Arabic (CRBS-A), as well as strategies to mitigate them. The CRBS was translated by two bilingual health professionals independently, followed by back-translation. Next, 19 healthcare providers, followed by 19 patients rated the face and content validity (CV) of the pre-final versions, providing input to improve cross-cultural applicability. Then, 207 patients from Saudi Arabia and Jordan completed the CRBS-A, and factor structure, internal consistency, construct, and criterion validity were assessed. Helpfulness of mitigation strategies was also assessed. For experts, item and scale CV indices were 0.8-1.0 and 0.9, respectively. For patients, item clarity and mitigation helpfulness scores were 4.5 ± 0.1 and 4.3 ± 0.1/5, respectively. Minor edits were made. For the test of structural validity, four factors were extracted: time conflicts/lack of perceived need and excuses; preference to self-manage; logistical problems; and health system issues and comorbidities. Total CRBS-A α was 0.90. Construct validity was supported by a trend for an association of total CRBS with financial insecurity regarding healthcare. Total CRBS-A scores were significantly lower in patients who were referred to CR (2.8 ± 0.6) vs. those who were not (3.6 ± 0.8), confirming criterion validity (p = 0.04). Mitigation strategies were considered very helpful (mean = 4.2 ± 0.8/5). The CRBS-A is reliable and valid. It can support identification of top barriers to CR participation at multiple levels, and then strategies for mitigating them can be implemented.

Surveillance of the Initiation of, Participation in, and Completion of Cardiac Rehabilitation in Minnesota, 2017-2018.

Cardiac rehabilitation (CR) is an evidence-based secondary prevention program designed to improve cardiovascular health after a cardiac event. The objective of our study was to identify gaps in CR use among publicly and privately insured people in Minnesota to assist in developing shared goals among public health, cardiac rehabilitation professionals, and program delivery sites to improve CR delivery. We applied a published claims-based surveillance methodology to the Minnesota All Payer Claims Database to assess eligibility for, initiation of, participation in, and completion of CR by patients with qualifying events in 2017. We stratified results by sociodemographic and geographic factors and qualifying condition and used adjusted prevalence ratios to make statistical comparisons. Less than half (47.6%) of qualifying patients initiated CR within 1 year of their qualifying event; the rate was higher among men (vs women), adults aged 45 to 64 years (vs ≥65 y), and patients with commercial or Medicaid insurance coverage (vs Medicare). Among those who initiated CR, only 14.0% completed the full series of 36 sessions. Participation in at least 12 sessions and completion of 36 sessions was less likely among adults aged 18 to 64 (vs 65-74 y) and among patients covered by Medicaid (vs Medicare). Patterns of CR initiation, participation, and completion also varied geographically. This analysis expands on previous Medicare fee-for-service population CR surveillance and provides a first detailed look at the CR landscape in Minnesota, renewing attention to CR as a key secondary prevention strategy. Collaboration and sharing with partners has established the Minnesota Department of Health as a valuable partner in driving health system change to improve equitable provision of CR in Minnesota.

Effects of Low- and High-Frequency Cardiac Rehabilitation on Risk Factors, Physical Fitness and Quality of Life in Middle-Aged Women with Coronary Heart Disease.

Cardiac rehabilitation (CR) is a system that comprehensively manages risk factors to reduce the recurrence rate after cardiovascular disease treatment. This study compared the effects of home-based low-frequency CR (1-2 times/week) and center-based high-frequency CR (3-5 times/week) for 12 weeks. This study was conducted as an observational case-control study. Ninety women, ages 45 to 60, who underwent coronary artery stenting were enrolled. Measurement variables were waist circumference, body mass index (BMI), blood pressure (BP), total cholesterol (TC), low-density lipoprotein cholesterol (LDLC), high-density lipoprotein cholesterol (HDLC), triglycerides (TG), glucose, VO2 peak, body composition, and quality of life. Significant changes were observed in systolic BP, TC, LDLC, TG, VO2 peak, exercise duration, and quality of life in both groups. However, BMI, waist circumference, body fat percentage, HDLC, and blood glucose only exhibited significant changes with HFT. The interaction effects according to time and group were as follows: systolic BP, waist circumference, body fat, BMI, HDLC, and glucose (p < 0.05). Therefore, in CR participants, HFT improved more than LFT on obesity factors, HDLC, and glucose change. As well as center-based HFT, home-based LFT also improved risk factors for cardiovascular disease, fitness, and quality of life. For female patients who have difficulty visiting the CR center frequently, home-based LFT may be a CR program that can be presented as an alternative.

Advances, Challenges, and Progress in Cardiac Rehabilitation in Chronic CVD Management.

To review the benefits, challenges, and advances in cardiac rehabilitation (CR) in the management of cardiovascular disease (CVD). Novel strategies of delivering CR are being studied that use remote technologies to link patients with CR professionals. These strategies used alone or in tandem with center-based, face-to-face strategies appear to have shorter-term effectiveness, but additional work is needed to assess the longer-term impact. Cardiac rehabilitation improves patient outcomes, but only a minority of eligible individuals participate. Solutions exist to help bridge the barriers to CR participation, including systematic solutions, such as automatic CR referral of eligible patients. Efforts are underway to improve participation, improve the effectiveness of CR therapies, and enhance the reach of CR into new patient groups. Future work in the field is focused on opportunities to advance the science, practice, and policies that will shape and improve the delivery and impact of CR services.

Financial incentives and case management to improve cardiac rehabilitation participation among patients with lower socio-economic status: Rationale and protocol for a randomized controlled trial

BackgroundParticipation in phase 2 cardiac rehabilitation (CR) is associated with significant decreases in morbidity and mortality. Unfortunately, attendance at CR is not optimal and certain populations, such as those with lower-socioeconomic status (SES), are less likely to participate. In order to remedy this disparity we have designed a trial to examine the efficacy of early case management and/or financial incentives for increasing CR participation among lower-SES patients. MethodsWe will employ a randomized controlled trial with a sample goal of 209 patients who will be randomized 2:3:3:3 to either a usual care control, to receive a case manager starting in-hospital, to receive financial incentives for completing CR sessions, or to receive both interventions. ResultsTreatment conditions will be compared on attendance at CR and end-of-intervention (four months) improvements in cardiorespiratory fitness, executive function, and health-related quality of life. The primary outcome measures for this project will be number of CR sessions completed and the percentage who complete ≥30 sessions. Secondary outcomes will include improvements in health outcomes by condition, as well as the cost-effectiveness of the intervention with a focus on potential reductions in emergency department visits and hospitalizations. We hypothesize that either intervention will perform better than the control and that the combination of interventions will perform better than either alone. ConclusionsThis systematic examination of interventions will allow us to test the efficacy and cost-effectiveness of approaches that have the potential to increase CR participation substantially and significantly improve health outcomes among patients with lower-SES.

Factors Associated With Changes in Objectively Measured Moderate to Vigorous Physical Activity in Patients After Percutaneous Coronary Intervention: A Prospective Cohort Study.

This study aimed to clarify factors affecting changes in moderate to vigorous physical activity (MVPA) in patients 1 to 3months after undergoing percutaneous coronary intervention (PCI). In this prospective cohort study, we enrolled patients aged <75years who underwent PCI. MVPA was objectively measured using an accelerometer at 1 and 3months after hospital discharge. Factors associated with increased MVPA (≥150min/wk at 3mo) were analyzed in participants with MVPA < 150minutes per week at 1month. Univariate and multivariate logistic regression analyses were performed to explore variables potentially associated with increasing MVPA, using MVPA ≥ 150minutes per week at 3months as the dependent variable. Factors associated with decreased MVPA (<150min/wk at 3mo) were also analyzed in participants with MVPA ≥ 150minutes per week at 1month. Logistic regression analysis was performed to explore factors of declining MVPA, using MVPA < 150minutes per week at 3months as the dependent variable. We analyzed 577 patients (median age 64y, 13.5% female, and 20.6% acute coronary syndrome). Increased MVPA was significantly associated with participation in outpatient cardiac rehabilitation (odds ratio 3.67; 95% confidence interval, 1.22-11.0), left main trunk stenosis (13.0; 2.49-68.2), diabetes mellitus (0.42; 0.22-0.81), and hemoglobin (1.47, per 1 SD; 1.09-1.97). Decreased MVPA was significantly associated with depression (0.31; 0.14-0.74) and Self-Efficacy for Walking (0.92, per 1 point; 0.86-0.98). Identifying patient factors associated with changes in MVPA may provide insight into behavioral changes and help with individualized PA promotion.
