Efficacy and Adherence Rates of a Novel Community-Informed Virtual World-Based Cardiac Rehabilitation Program: Protocol for the Destination Cardiac Rehab Randomized Controlled Trial.

BACKGROUND: Innovative restructuring of cardiac rehabilitation (CR) delivery remains critical to reduce barriers and improve access to diverse populations. Destination Cardiac Rehab is a novel virtual world technology-based CR program delivered through the virtual world platform, Second Life, which previously demonstrated high acceptability as an extension of traditional center-based CR. This study aims to evaluate efficacy and adherence of the virtual world-based CR program compared with center-based CR within a community-informed, implementation science framework. METHODS: Using a noninferiority, hybrid type 1 effectiveness-implementation, randomized controlled trial, 150 patients with an eligible cardiovascular event will be recruited from 6 geographically diverse CR centers across the United States. Participants will be randomized 1:1 to either the 12-week Destination Cardiac Rehab or the center-based CR control groups. The primary efficacy outcome is a composite cardiovascular health score based on the American Heart Association Life's Essential 8 at 3 and 6 months. Adherence outcomes include CR session attendance and participation in exercise sessions. A diverse patient/caregiver/stakeholder advisory board was assembled to guide recruitment, implementation, and dissemination plans and to contextualize study findings. The institutional review board-approved randomized controlled trial will enroll and randomize patients to the intervention (or control group) in 3 consecutive waves/year over 3 years. The results will be published at data collection and analyses completion. CONCLUSIONS: The Destination Cardiac Rehab randomized controlled trial tests an innovative and potentially scalable model to enhance CR participation and advance health equity. Our findings will inform the use of effective virtual CR programs to expand equitable access to diverse patient populations.

Geographic Variation in Access to Cardiac Rehabilitation.

BACKGROUND: There is marked geographic variation in cardiac rehabilitation (CR) initiation, ranging from 10% to 40% of eligible patients at the state level. The potential causes of this variation, such as patient access to CR centers, are not well studied. OBJECTIVES: The authors sought to determine how access to CR centers affects CR initiation in Medicare beneficiaries. METHODS: The authors used Medicare files to identify CR-eligible Medicare beneficiaries and calculate CR initiation rates at the hospital referral region (HRR) level. We used linear regression to evaluate the percent variation in CR initiation accounted for by CR access across HRRs. We then employed geospatial hotspot analysis to identify CR deserts, or counties in which patient load per CR center is disproportionately high. RESULTS: A total of 1,133,657 Medicare beneficiaries were eligible for CR from 2014 to 2017, of whom 263,310 (23%) initiated CR. The West North Central Census Division had the highest adjusted CR initiation rate (35.4%) and the highest density of CR programs (6.58 per 1,000 CR-eligible Medicare beneficiaries). Density of CR programs accounted for 21.2% of geographic variation in CR initiation at the HRR level. A total of 40 largely urban counties comprising 14% of the United States population age ≥65 years had disproportionately low CR access and were identified as CR deserts. CONCLUSIONS: A substantial proportion of geographic variation in CR initiation was related to access to CR programs, with a significant amount of the U.S. population living in CR deserts. These data invite further study on interventions to increase CR access.

Systems of Care for ST-Segment-Elevation Myocardial Infarction: A Policy Statement From the American Heart Association.

The introduction of Mission: Lifeline significantly increased timely access to percutaneous coronary intervention for patients with ST-segment-elevation myocardial infarction (STEMI). In the years since, morbidity and mortality rates have declined, and research has led to significant developments that have broadened our concept of the STEMI system of care. However, significant barriers and opportunities remain. From community education to 9-1-1 activation and emergency medical services triage and from emergency department and interfacility transfer protocols to postacute care, each critical juncture presents unique challenges for the optimal care of patients with STEMI. This policy statement sets forth recommendations for how the ideal STEMI system of care should be designed and implemented to ensure that patients with STEMI receive the best evidence-based care at each stage in their illness.

Routine Assessment and Promotion of Physical Activity in Healthcare Settings: A Scientific Statement From the American Heart Association.

Physical inactivity is one of the most prevalent major health risk factors, with 8 in 10 US adults not meeting aerobic and muscle-strengthening guidelines, and is associated with a high burden of cardiovascular disease. Improving and maintaining recommended levels of physical activity leads to reductions in metabolic, hemodynamic, functional, body composition, and epigenetic risk factors for noncommunicable chronic diseases. Physical activity also has a significant role, in many cases comparable or superior to drug interventions, in the prevention and management of >40 conditions such as diabetes mellitus, cancer, cardiovascular disease, obesity, depression, Alzheimer disease, and arthritis. Whereas most of the modifiable cardiovascular disease risk factors included in the American Heart Association's My Life Check - Life's Simple 7 are evaluated routinely in clinical practice (glucose and lipid profiles, blood pressure, obesity, and smoking), physical activity is typically not assessed. The purpose of this statement is to provide a comprehensive review of the evidence on the feasibility, validity, and effectiveness of assessing and promoting physical activity in healthcare settings for adult patients. It also adds concrete recommendations for healthcare systems, clinical and community care providers, fitness professionals, the technology industry, and other stakeholders in order to catalyze increased adoption of physical activity assessment and promotion in healthcare settings and to contribute to meeting the American Heart Association's 2020 Impact Goals.

Cardiac rehabilitation and readmissions after heart transplantation.

BACKGROUND: Exercise-based cardiac rehabilitation (CR) is under-utilized. CR is indicated after heart transplantation, but there are no data regarding CR participation in transplant recipients. We characterized current CR utilization among heart transplant recipients in the United States and the association of CR with 1-year readmissions using the 2013-2014 Medicare files. METHODS: The study population included Medicare beneficiaries enrolled due to disability (patients on the transplant list are eligible for disability benefits under Medicare regulations) or age ≥65 years. We identified heart transplant patients by diagnosis codes and cumulative CR sessions occurring within 1 year after the transplant hospitalization. RESULTS: There were 2,531 heart transplant patients in the USA in 2013, of whom 595 (24%) received Medicare coverage and were included in the study. CR utilization was low, with 326 patients (55%) participating in CR programs. The Midwest had the highest proportion of transplant recipients initiating CR (68%, p = 0.001). Patients initiating CR attended a mean of 26.7 (standard deviation 13.3) sessions, less than the generally prescribed program of 36 sessions. Transplant recipients age 35 to 49 years were less likely to initiate CR (odds ratio [OR] 0.39, 95% confidence interval [CI] 0.23 to 0.66, p < 0.001) and attended 8.2 fewer sessions (95% CI 3.5 to 12.9, p < 0.001) than patients age ≥65 years. CR participation was associated with a 29% lower 1-year readmission risk (95% CI 13% to 42%, p = 0.001). CONCLUSIONS: Only half of cardiac transplant recipients participate in CR, and those who do have a lower 1-year readmission risk. These data invite further study on barriers to CR in this population.

Advocacy for outpatient cardiac rehabilitation globally.

BACKGROUND: Cardiovascular diseases (CVD) are the leading cause of death globally. Cardiac rehabilitation (CR) is an evidence-based intervention recommended for patients with CVD, to prevent recurrent events and to improve quality of life. However, despite the proven benefits, only a small percentage of those would benefit from CR actually receive it worldwide. This paper by the International Council of Cardiovascular Prevention and Rehabilitation forwards the groundwork for successful CR advocacy to achieve broader reimbursement, and hence implementation. METHODS: First, the results of the International Council's survey on national CR reimbursement policies by government and insurance companies are summarized. Second, a multi-faceted approach to CR advocacy is forwarded. Finally, as per the advocacy recommendations, the economic impact of CVD and the corresponding benefits of CR and its cost-effectiveness are summarized. This provides the case for CR reimbursement advocacy. RESULTS: Thirty-one responses were received, from 25 different countries: 18 (58.1 %) were from high-income countries, 10 (32.4 %) from upper middle-income, and 3 (9.9 %) from lower middle-income countries. When asked who reimburses at least some portion of CR services in their country, 19 (61.3 %) reported the government, 17 (54.8 %) reported patients pay out-of-pocket, 16 (51.6 %) reported insurance companies, 12 (38.7 %) reported that it is shared between the patient and another source, and 7 (22.6 %) reported another source. CONCLUSIONS: Many patients pay out-of-pocket for CR. CR reimbursement around the world is inconsistent and insufficient. Advocacy campaigns forwarding the CR cause, supported by the relevant literature, enlisting sources of support in a unified manner with an organized plan, are needed, and must be pursued persistently.

Cardiac rehabilitation in low- and middle-income countries: a review on cost and cost-effectiveness.

BACKGROUND: By 2030, more than 80% of cardiovascular disease-related deaths and disability-adjusted life years will occur in the 139 low- and middle-income (LMIC) countries. Cardiac rehabilitation (CR) has been demonstrated to be effective and cost-effective mainly based on data from high-income countries. The purpose of this paper was to review the literature for cost and cost-effectiveness data on CR in LMICs. METHODS: MEDLINE (Ovid) and EMBASE (Ovid) electronic databases were searched for CR 'cost' and 'cost-effectiveness' data in LMICs. RESULTS: Five CR publications with cost and cost-effectiveness data from middle-income countries were identified with none from low-income countries. Studies from Brazil demonstrated mean monthly savings of US$190 for CR, with a US$48 increase in a control group with mean costs of US$503 for a 3-month CR program. Mean costs to the public health care system of US$360 and US$540 when paid out-of-pocket were reported for a 3-month CR program in seven Latin American middle-income countries. Cardiac rehabilitation is reported to be cost-effective in both Brazil and Colombia. CONCLUSIONS: Cardiac rehabilitation for patients with heart failure in Brazil and Colombia was estimated to be cost-effective. However, given the limited health care budgets in many LMICs, affordable CR models will need to be developed for LMICs, particularly for low-income countries.

Ethnocultural diversity in cardiac rehabilitation.

Cardiovascular disease is the leading cause of death globally. Despite a greater burden of disease, ethnocultural minorities in both the United States and Canada are significantly less likely to access cardiac rehabilitation (CR). Without equitable access to CR, these patients may be more likely to experience recurrent cardiac events and unnecessarily premature death. In this article, the current state of ethnocultural diversity in CR patients and unique barriers that ethnocultural minority patients face are reviewed. Strategies for CR program delivery and diversity of CR program staff are considered. Guidance on ethnocultural considerations in American and Canadian associations of CR is also reviewed. Lower rates of access to CR are seen among ethnocultural minorities in both American and Canadian CR programs. Only 2 studies evaluating ethnoculturally tailored CR could be identified in the literature. American CR staff are predominantly white (∼96%), whereas ethnocultural data are not collected from Canadian CR professionals. American guidelines emphasize the importance of ethnocultural competency. Meanwhile, Canadian guidelines underscore the low use of CR services among ethnocultural minorities, and support ethnoculturally informed CR delivery. The American and Canadian populations are rapidly diversifying, yet the CR workforce is not, and ethnocultural minorities continue to be underrepresented in our programs. Although recent CR guidelines have made some preliminary recommendations to overcome these discrepancies, more focused efforts are needed. Thirteen points of action are proposed for the CR community with the goal of promoting the development and delivery of more ethnoculturally sensitive CR services.

The role of cardiac rehabilitation following acute coronary syndromes.

Growing evidence highlights the important role of post-hospitalization care (i.e., secondary prevention) for patients with an acute coronary syndrome (ACS). While secondary prevention therapies are available that improve patient outcomes, receipt of those treatments by patients is suboptimal. Cardiac rehabilitation/secondary prevention (CR/SP) services are systematic, effective models of care that improve delivery of preventive therapies and patient outcomes after ACS, but unfortunately, patient participation in CR/SP has been suboptimal, due to patient-, provider-, and system-based barriers. Systematic processes, including automatic referral processes, help reduce these barriers and improve CR/SP participation, along with the associated health benefits. Strength of physician endorsement of CR/SP participation is another key step in improving CR/SP participation and patient outcomes following ACS. Accountability measures for CR/SP referral and enrollment, including performance measures and other quality of care methods, may help improve CR/SP delivery. Early evidence suggests that these measures have helped improve referral of eligible patients to CR/SP programs.

A perspective on the New American College of Cardiology/American Heart Association guidelines for cardiovascular risk assessment.

The recently published American College of Cardiology (ACC)/American Heart Association (AHA) guidelines for cardiovascular risk assessment provide equations to estimate the 10-year and lifetime atherosclerotic cardiovascular disease (ASCVD) risk in African Americans and non-Hispanic whites, include stroke as an adverse cardiovascular outcome, and emphasize shared decision making. The guidelines provide a valuable framework that can be adapted on the basis of clinical judgment and individual/institutional expertise. In this review, we provide a perspective on the new guidelines, highlighting what is new, what is controversial, and potential adaptations. We recommend obtaining family history of ASCVD at the time of estimating ASCVD risk and consideration of imaging to assess subclinical disease burden in patients at intermediate risk. In addition to the adjuncts for ASCVD risk estimation recommended in the guidelines, measures that may be useful in refining risk estimates include carotid ultrasonography, aortic pulse wave velocity, and serum lipoprotein(a) levels. Finally, we stress the need for research efforts to improve assessment of ASCVD risk given the suboptimal performance of available risk algorithms and suggest potential future directions in this regard.

A summary and critical assessment of the 2013 ACC/AHA guideline on the treatment of blood cholesterol to reduce atherosclerotic cardiovascular disease risk in adults: filling the gaps.

The American College of Cardiology/American Heart Association (ACC/AHA) Task Force on Practice Guidelines has recently released the new cholesterol treatment guideline. This update was based on a systematic review of the evidence and replaces the previous guidelines from 2002 that were widely accepted and implemented in clinical practice. The new cholesterol treatment guideline emphasizes matching the intensity of statin treatment to the level of atherosclerotic cardiovascular disease (ASCVD) risk and replaces the old paradigm of pursuing low-density lipoprotein cholesterol targets. The new guideline also emphasizes the primacy of the evidence base for statin therapy for ASCVD risk reduction and lists several patient groups that will not benefit from statin treatment despite their high cardiovascular risk, such as those with heart failure (New York Heart Association class II-IV) and patients undergoing hemodialysis. The guideline has been received with mixed reviews and significant controversy. Because of the evidence-based nature of the guideline, there is room for several questions and uncertainties on when and how to use lipid-lowering therapy in clinical practice. The goal of the Mayo Clinic Task Force in the assessment, interpretation, and expansion of the ACC/AHA cholesterol treatment guideline is to address gaps in information and some of the controversial aspects of the newly released cholesterol management guideline using additional sources of evidence and expert opinion as needed to guide clinicians on key aspects of ASCVD risk reduction.

Incorporating patients with chronic heart failure into outpatient cardiac rehabilitation: practical recommendations for exercise and self-care counseling-a clinical review.

PURPOSE: A recent policy change from the Centers for Medicare and Medicaid Services includes coverage of cardiac rehabilitation (CR) for patients with chronic heart failure (CHF) with reduced ejection fraction. This article provides a framework by which CR programs can incorporate disease-specific services for patients with CHF who participate in CR. DISCUSSION: Cardiac rehabilitation should include self-care counseling that targets improved education and skill development (eg, medication compliance, monitoring/management of body weight). Various tools are available for assessing exercise tolerance (eg, stress test with gas exchange and 6-minute walk), health-related quality of life, and other outcome-related parameters. Exercise should be prescribed in a manner that progressively increases intensity, duration, and frequency, to a volume of exercise equivalent to 3 to 7 metabolic equivalent task (MET)-hr per week. The benefits of exercise training are limited by patient adherence; therefore, CR providers need to identify the adherence challenges unique to each patient and address each accordingly. To optimize the referral of patients with CHF to CR, program staff should develop strategies to raise both health care provider and patient awareness about the benefits of CR, as well as work collaboratively to set up system-based approaches to CR referral. CONCLUSIONS: The referral of patients with CHF to CR will increase in 2014 and beyond, due partly to a policy change from the Centers for Medicare and Medicaid Services that allows coverage for CR. These patients should be integrated into existing programs, with the intent of providing both standard CR services and CHF-specific education and disease management activities that target improved outcomes.

Commercial insurance coverage for outpatient cardiac rehabilitation in patients with heart failure in the United States.

BACKGROUND: Although cardiac rehabilitation (CR) improves outcomes in patients with heart failure (HF), studies suggest variable uptake by patients with HF, as well as variable coverage by insurance carriers. The purpose of this study was to determine the percentage of large commercial health insurance companies that provide coverage for outpatient (CR) for patients with HF. METHODS: We identified a sample of the largest US commercial health care providers and analyzed their CR coverage policies for patients with HF. We surveyed 44 large private health care insurance companies, reviewed company Web sites, and, when unclear, contacted companies by e-mail or telephone. We excluded insurance clearinghouses because they did not directly provide health care insurance. RESULTS: Of 44 eligible insurance companies, 29 (66%) reported that they provide coverage for outpatient CR in patients with HF. The majority of companies (83%) covered CR for patients with any type of HF. A minority (10%) did not cover CR for patients with HF if it was considered a preexisting condition. CONCLUSIONS: A significant percentage of commercial health care insurance companies in the United States report that they currently cover outpatient CR for patients with HF. Because health insurance coverage is associated with patient participation in CR, it is anticipated that patients with HF will increasingly participate in CR in coming years.

Combining body mass index with measures of central obesity in the assessment of mortality in subjects with coronary disease: role of "normal weight central obesity".

OBJECTIVES: This study sought to assess the mortality risk of patients with coronary artery disease (CAD) based ona combination of body mass index (BMI) with measures of central obesity. BACKGROUND: In CAD patients, mortality has been reported to vary inversely with BMI ("obesity paradox"). In contrast,central obesity is directly associated with mortality. Because of this bidirectionality, we hypothesized that CAD patients with normal BMI but central obesity would have worse survival compared to individuals with other combinations of BMI and central adiposity. METHODS: We included 15,547 participants with CAD who were part of 5 studies from 3 continents. Multivariate stratifiedCox-proportional hazard models adjusted for potential confounders were used to assess mortality risk according to different patterns of adiposity that combined BMI with measures of central obesity. RESULTS: Mean age was 66 years, 60% were men. There were 5,507 deaths over a median follow-up of 2.4 years (IQR: 0.5 to 7.4 years). Individuals with normal weight central obesity had the worst long-term survival: a person with BMI of 22 kg/m2 and waist circumference (WC) of 101 cm had higher mortality than a person with similar BMI but WC of 85 cm (HR: 1.10[95% CI: 1.05 to 1.17]), than a person with BMI of 26 kg/m2 and WC of 85 cm (HR: 1.20 [95% CI: 1.09 to 1.31]), than a person with BMI of 30 kg/m2 and WC of 85 cm (HR: 1.61 [95% CI: 1.39 to 1.86]) and than a person with BMI of 30kg/m2 and WC of 101 cm (HR: 1.27 [95% CI: 1.18 to 1.39), p < 0.0001 for all). CONCLUSIONS: In patients with CAD, normal weight with central obesity is associated with the highest risk of mortality [corrected].

Availability and characteristics of cardiovascular rehabilitation programs in South America.

PURPOSE: Cardiac rehabilitation (CR) programs decrease morbidity and mortality rates in patients with coronary artery disease, the leading cause of death in Latin America. This study was carried out to assess the characteristics and current level of CR program implementation in South America. METHODS: We carried out a survey of CR programs that were identified using the directory of the South American Society of Cardiology and through an exhaustive search by the investigators. RESULTS: We identified 160 CR programs in 9 of the 10 countries represented in the South American Society of Cardiology and 116 of those responded to our survey. On the basis of survey results from the responding programs, we estimate that the availability of CR programs in South America is extremely low, approximately 1 CR program for every 2 319 312 inhabitants. These CR programs provided services to a median of 180 patients per year (interquartile range, 60-400) and were most commonly led by cardiologists (84%) and physical therapists (72%). Phases I, II, III, and IV CR were offered in 49%, 91%, 89%, and 56% of the centers, respectively. The most commonly perceived barrier to participation in a CR program was lack of referral from the cardiologist or primary care physician, as reported by 70% of the CR program directors. CONCLUSIONS: The number of CR programs in South America appears to be insufficient for a population with a high and growing burden of cardiovascular disease. In addition, there appears to be a significant need for standardization of CR program components and services in the region.

Cardiac rehabilitation and cardiovascular disability: role in assessment and improving functional capacity: a position statement from the American Association of Cardiovascular and Pulmonary Rehabilitation.

The Social Security Administration (SSA) oversees the disability determination process and the payment of disability benefits to Americans. According to recent SSA data, approximately 900 000 persons are receiving cardiovascular disability payments and about 145 000 adult claims for cardiovascular disability are processed by the SSA annually. An objective and comprehensive examination of functional capacity is an important part of the disability assessment process. This statement reviews various protocols for disability assessment of aerobic capacity, muscle function, and the physical requirements of job tasks. Cardiac rehabilitation programs are ideal settings for conducting comprehensive disability assessments of functional capacity in persons with cardiovascular disease. In addition, exercise training provided by cardiac rehabilitation programs can increase functional capacity in most patients.
