Characteristics and Outcomes of Cardiac Rehabilitation Patients With and Without Cancer: Insights From Western Sydney.

AIM: Increased cardiovascular events are common in cancer survivors and contribute to an emerging cardio-oncology patient group requiring secondary prevention strategies including cardiac rehabilitation (CR). This study aimed to compare characteristics and outcomes for patients participating in CR with and without an existing cancer diagnosis. METHOD: Observational cohort study including consecutive patients enrolled in a single-centre outpatient CR program in Western Sydney between 2018-2022. Clinical history, demographics and CR outcome data were collected as part of standard care at program enrolment and completion. Patients with and without a cancer diagnosis were compared at enrolment and outcomes were analysed in both groups. RESULTS: A total of 1,792 patients enrolled in CR, 191 (11%) had a documented history of cancer; prostate (18%), skin (12%), colon (9%) and breast (8%) malignancies were most prevalent. The most common treatments were surgical resection (80%) and chemotherapy or radiotherapy (37%). Cardio-oncology patients were older (68.8±10.6 vs 59.8±13.7yrs, p<0.001), more likely female (33% vs 21%, p<0.001), born in Australia (46% vs 35%, p=0.004), non-partnered (34% vs 25%, p=0.002) and had a prior history of hypertension (65% vs 56%, p=0.010) or stroke (8% vs 5%, p=0.045). After adjusting for age and sex, the overall cohort improved their mean peak exercise capacity and waist circumference after CR, however there were no differences between groups. There were also no between-group differences for adherence and completion of CR program or any other cardiovascular risk factors. Sub-analyses revealed a clinically meaningful improvement in waist circumference for cancer patients with a history of radiation therapy and a blunted peak exercise capacity adaptation for those with a history of chemotherapy treatment. CONCLUSIONS: Despite differences in demographic and clinical characteristics of CR patients with and without cancer, all patients showed significant and clinically relevant improvements in peak exercise capacity and waist circumference after CR. Results also highlighted potential associations between specific cancer treatments and changes in fitness outcomes, which warrants further evaluation.

A National Survey of Patient Data Capture, Management, Reporting Practice in Australian Cardiac Rehabilitation Programs.

BACKGROUND: Lack of service data for cardiac rehabilitation limits understanding of program delivery, benchmarking and quality improvement. This study aimed to describe current practices, management, utilisation and engagement with quality indicators in Australian programs. METHOD: Cardiac rehabilitation programs (n=396) were identified from national directories and networks. Program coordinators were surveyed on service data capture, management systems and adoption of published national quality indicators. Text responses were coded and classified. Logistic regression determined independent associates of the use of data for quality improvement. RESULTS: A total of 319 (81%) coordinators completed the survey. Annual patient enrolments/programs were >200 (31.0%), 51-200 (46%) and ≤50 (23%). Most (79%) programs used an electronic system, alongside paper (63%) and/or another electronic system (19%), with 21% completely paper. While 84% knew of the national quality indicators, only 52% used them. Supplementary to patient care, data were used for reports to managers (57%) and funders (41%), to improve quality (56%), support funding (43%) and research (31%). Using data for quality improvement was more likely when enrolments where >200 (Odds ratio [OR] 3.83, 95% Confidence Interval [CI] 1.76-8.34) and less likely in Victoria (OR 0.24 95%, CI 0.08-0.77), New South Wales (OR 0.25 95%, CI 0.08-0.76) and Western Australia (OR 0.16 95%, CI 0.05-0.57). CONCLUSIONS: The collection of service data for cardiac rehabilitation patient data and its justification is diverse, limiting our capacity to benchmark and drive clinical practice. The findings strengthen the case for a national low-burden approach to data capture for quality care.

Effect of an avatar-based discharge education application on knowledge and behaviour in people after acute coronary syndrome: protocol for a pragmatic prospective randomised controlled trial.

INTRODUCTION: Many hospital presentations for acute coronary syndrome (ACS) occur in people previously hospitalised with coronary heart disease (CHD), leading to increased costs and health burden. Secondary prevention education including a prehospital discharge plan is recommended for all individuals to reduce the risk of recurrence. However, many clinicians lack the time or support to provide education, and patients' uptake of secondary prevention programmes is limited. An avatar-based education app is a novel and engaging way to provide self-delivered, evidence-based secondary prevention information during the hospital admission and remains accessible after discharge. This protocol aims to evaluate the effect of an avatar-based education app on individuals with ACS. METHODS AND ANALYSIS: This protocol describes a prospective, randomised controlled trial with 3-month follow-up and blinded assessment of 72 participants. Intervention group participants will download the app onto their own device during the hospital admission and independently complete six interactive education modules based on the National Heart Foundation's six steps to cardiac recovery. All participants will receive a text message reminder of the study after 3 weeks. Both groups will receive usual care consisting of bedside education and a pamphlet about cardiac rehabilitation. The primary outcome is knowledge of CHD, assessed using the Coronary Artery Disease Education Questionnaire II. Secondary outcomes include quality of life, response to heart attack symptoms, cardiac-related readmissions and mortality and modifiable cardiac risk factors. Engagement with the app will be evaluated objectively. Intention-to-treat analysis will be conducted, with between-group comparisons and 95% CIs of the primary outcome analysed using analysis of covariance, adjusting for baseline values. ETHICS AND DISSEMINATION: This study protocol has been approved by the Western Sydney Local Health District Human Research Ethics Committee. The results of this study will be disseminated via a peer-reviewed journal and research thesis. TRIAL REGISTRATION NUMBER: Australian New Zealand Clinical Trials Registry (ACTRN12622001436763).

Feasibility of Integrating MEditatioN inTO heaRt Disease (the MENTOR Study): A Phase II Randomized Controlled Trial.

BACKGROUND: Comorbid depression and/or anxiety symptoms occur in 25% of patients attending cardiac rehabilitation (CR) programs and are associated with poorer prognosis. There is a need to evaluate psychological interventions, including meditation, that have potential to improve psychological health in CR programs. AIMS: The aim of this study was to determine the feasibility and acceptability of integrating a meditation intervention into an existing Australian CR program for the reduction of depression and anxiety symptoms. METHODS: This was a mixed-methods feasibility randomized controlled trial. Thirty-one patients with CVD and, at a minimum, mild depression and/or anxiety symptoms were randomized to meditation and standard CR or to standard CR alone. A 16-minute guided group meditation was delivered face-to-face once a week for 6 weeks, with daily self-guided meditation practice between sessions. Feasibility outcomes included screening, recruitment, and retention. Semistructured interviews of patients' (n = 10) and health professionals' (n = 18) perspectives of intervention participation and delivery were undertaken to assess acceptability. Between-group differences in depression, anxiety, stress, self-efficacy for mindfulness, and health status at 6 and 12 weeks were also assessed. RESULTS AND CONCLUSION: Meditation was considered feasible, with 83% (12/15) of the intervention group completing an average of 3.13 (SD, 2.56) out of 6 group meditation sessions and 5.28 (SD, 8.50) self-guided sessions. Meditation was considered acceptable by patients, clinicians, and health managers. Between-group differences in the number of CR sessions completed favored the intervention group in per-protocol analyses (intervention group vs control group, 12 vs 9 sessions; P = .014), which suggests that meditation may be useful to improve patients' adherence to exercise-based CR program.

Impact of Early COVID-19 Waves on Cardiac Rehabilitation Delivery in Australia: A National Survey.

BACKGROUND: The novel coronavirus disease of 2019 (COVID-19) pandemic significantly disrupted health care, especially outpatient services such as cardiac rehabilitation (CR). We investigated the impact of early COVID-19 waves on the delivery of Australian CR programs, comparing this time period with usual practice prior to the pandemic (2019) and current practice (2021) once the early waves had subsided. Specifically, we aimed to understand how the delivery of programs during COVID-19 compared to usual practice. METHODS: An anonymous online cross-sectional survey of Australian CR program staff was conducted, comprising three sections: program and respondent characteristics, COVID-19 impact on program delivery, and barriers to, and enablers of, program delivery. Respondents were asked to consider three key timepoints: 1) Pre-COVID-19 (i.e. usual practice in 2019), 2) Early COVID-19 waves (March-December 2020), and 3) Currently, at time of survey completion post early COVID-19 waves (May-July 2021). RESULTS: Of the 314 Australian CR programs, 115 responses were received, of which 105 had complete data, representing a 33% response rate. All states and territories were represented. During early COVID-19 waves programs had periods of closure (40%) or reduced delivery (70%). The majority of programs reported decreased CR referrals (51.5%) and decreased participation (77.5%). The two core components of CR-exercise and education-were significantly impacted during early COVID-19 waves, affecting both the number and duration of sessions provided. Exercise session duration did not return to pre-pandemic levels (53.5 min compared to 57.7 min, p=0.02). The majority of respondents (77%) reported their CR program was inferior in quality to pre-pandemic and more organisational support was required across information technology, staffing, administration and staff emotional and social support. CONCLUSION: Australian CR programs underwent significant change during the early COVID-19 waves, consistent with international CR reports. Fewer patients were referred and attended CR and those who did attend received a lower dose of exercise and education. It will be important to continue to monitor the long-term impacts of the COVID-19 pandemic to ensure CR programs return to pre-pandemic functioning and continue to deliver services in line with best practice and evidence-based recommendations.

Determinants of Exercise Capacity Following ST-Elevation Myocardial Infarction (STEMI).

BACKGROUND: Abnormal left ventricular systolic and diastolic function and reduced exercise capacity are associated with worse prognosis following ST-elevation myocardial infarction (STEMI). However, evidence is lacking on the determinants of exercise capacity following STEMI. We sought to determine the impact of systolic and diastolic dysfunction on exercise capacity and outcomes following first-ever STEMI. METHODS: In a retrospective analysis of 139 consecutive STEMI patients who had a transthoracic echocardiogram following STEMI and completed exercise treadmill testing, the primary outcome was to identify clinical and echocardiographic determinants of exercise capacity, and the secondary outcome was to identify determinants of major adverse cardiac events (MACEs). RESULTS: Mean number of metabolic equivalents (METs > 8) was used as a cut-off. Age, female sex, anterior infarction, abnormal diastolic function, minimum left atrial indexed volume (LAVImin) ≥ 18 mL/m2, average e', and E/e' were associated with METs ≤ 8, but not left ventricular ejection fraction (LVEF). On multivariate analysis, LAVImin (OR 4.3, 95%CI 1.3-14.2; p = 0.017), anterior infarction (OR 2.6, 95%CI 1.2-5.9; p = 0.022), and abnormal diastolic function (OR 3.73, 95%CI 1.7-8.4; p = 0.001) were independent predictors of METs ≤ 8. On Kaplan-Meier analysis, METs ≤ 8 (p = 0.01) and abnormal diastolic function (p = 0.04) were associated with MACEs (median follow-up 2.3 years). METs ≤ 8 was an independent predictor of MACEs (HR 3.4, 95%CI 1.2-9.8; p = 0.02). CONCLUSIONS: Following first-ever STEMI, increased LAVImin, anterior infarction, and abnormal diastolic function were independent predictors of reduced exercise capacity. Furthermore, reduced exercise capacity was an independent predictor of MACEs. These results highlight important prognostic and therapeutic implications related to abnormal diastolic function in STEMI patients that are distinct from those with LV systolic impairment.

The Role of Lifestyle and Cardiovascular Risk Factors in Dropout From an Australian Cardiac Rehabilitation Program. A Longitudinal Cohort Study.

BACKGROUND: Cardiac rehabilitation (CR) programs reduce the risk of further cardiac events and improve the ability of people living with cardiovascular disease to manage their symptoms. However, many people who experience a cardiac event do not attend or fail to complete their CR program. Little is known about the characteristics of people who drop out compared to those who complete CR. AIMS: To identify subgroups of patients attending a cardiac rehabilitation program who are more likely to dropout prior to final assessment by (1) calculating the dropout rate from the program, (2) quantifying the association between dropout and socio-demographic, lifestyle, and cardiovascular risk factors, and (3) identifying independent predictors of dropout. METHODS: The study population is from a large metropolitan teaching hospital in Sydney, Australia, and consists of all participants consecutively enrolled in an outpatient CR program between 2006 and 2017. Items assessed included diagnoses and co-morbidities, quality of life (SF-36), psychological health (DASS-21), lifestyle factors and physical assessment. Dropout was defined as failure to complete the outpatient CR program and post CR assessment. RESULTS: Of the 3,350 patients enrolled in the CR program, 784 (23.4%; 95%CI: 22.0-24.9%) dropped out prior to completion. The independent predictors of dropout were smoking (OR 2.4; 95%CI: 1.9-3.0), being separated or divorced (OR 2.0; 95%CI: 1.5-2.6), younger age (<55 years) (OR 1.9; 95%CI: 1.6-2.4), obesity (OR 1.6; 95%CI: 1.3-2.0), diabetes (OR 1.6; 95%CI: 1.3-2.0), sedentary lifestyle (OR 1.3; 95%CI: 1.1-1.6) and depressive symptoms (OR 1.3; 95%CI: 1.1-1.6). CONCLUSION: To improve the CR program completion rate, clinicians need to consider the impact of socio-demographic, lifestyle, and cardiovascular risk factors on their patients' ability to complete CR. Tailored strategies which target the independent predictors of dropout are required to promote adherence to CR programs and thereby potentially reduce long-term cardiovascular risk.

Shorter Wait Times to Cardiac Rehabilitation Associated With Greater Exercise Capacity Improvements: A MULTISITE STUDY.

PURPOSE: Comprehensive exercise-based cardiac rehabilitation (CR) results in improved, though highly variable, exercise capacity outcomes. Whether modifiable factors such as CR program wait time and session duration are associated with exercise capacity outcomes has not been adequately investigated. METHODS: Patients with coronary heart disease (±primary and elective percutaneous coronary interventions, cardiac surgery) who participated in CR programs involved in a three-state audit (n = 32 sites) were eligible. Exercise capacity was measured using the 6-min walk test before and after a 6- to 12-wk supervised exercise program. CR program characteristics were also recorded (wait time, number of sessions). Correlations and linear mixed-effects models were used to identify associations between sociodemographic and CR program characteristics and change in exercise capacity. RESULTS: Patients (n = 894) had a mean age of 65.9 ± 11.8 yr, 71% were males, 33% were referred for cardiac surgery, and median wait time was 16 d (interquartile range 9, 26). Exercise capacity improved significantly and clinically (mean increase 70.4 ± 61.8 m). After adjusting for statistically significant factors including younger age (<50 vs ≥80 yr [ß = 52.07]), female sex (ß = -15.86), exercise capacity at CR entry (ß = 0.22) and those nonsignificant (ethnicity, risk factors, and number of sessions), shorter wait time was associated with greater exercise capacity improvement (ß = 0.23). CONCLUSIONS: This study confirms that greater exercise capacity improvements occur with shorter wait times. Coordinators should prioritize implementing strategies to shorten wait time to optimize the benefits of CR.

Evaluation of Cardiac Rehabilitation Performance and Initial Benchmarks for Australia: An Observational Cross-State and Territory Snapshot Study.

BACKGROUND: Australia, unlike most high-income countries, does not have published benchmarks for cardiac rehabilitation (CR) delivery. This study provides cross-state data on CR delivery for initial benchmarks and assesses performance against international minimal standards. METHODS: A prospective observational study March-May 2017 of CR programs in NSW (n=36), Tasmania (n=2) and ACT (n=1) was undertaken. Data were collected on 11 indicators (published dictionary), then classified as higher or lower performing using the UK National Audit of Cardiac Rehabilitation (NACR) criteria. Equity of access to higher performing CR was assessed using logistic regression. RESULTS: Participants (n=2,436) had a mean age of 66.06±12.54 years, 68.9% were male, 16.2% culturally and linguistically diverse (CALD) and 2.6% Aboriginal and Torres Strait Islander peoples. At patient level, waiting time was median 15 (Interquartile range [IQR] 9-25) days, 24.3% had an assessment before starting, 41.8% on completion, a median 12 sessions (IQR 6-16) were delivered, which 59.1% completed and 75.4% were linked to ongoing care. At program level, using NACR criteria, 18.0% were classified as higher performing and ≥87.1% met waiting time criteria, however, only 20.5% met duration criteria. Evidence of inequitable access to higher performing programs was present with substantially higher odds for participants living in major cities (OR 28.11 95%CI 18.41, 44.92) and with every decade younger age (OR 1.89-2.94) and lower odds by 89.0% for principal referral hospital-based services (OR 0.11 95%CI 0.08, 0.14) and 31.0% for people having a CALD background (OR 0.69 95%CI 0.49, 0.97). CONCLUSIONS: This study provides initial national CR performance benchmarks for quality improvement in Australia. While wait times are minimised, few programs are higher performing or met minimum duration standards. There is an urgent need to resource and support CR quality and access outside of major cities, in principal referral hospitals and for older and diverse patients.

Development of Quality Indicators for Cardiac Rehabilitation in Australia: A Modified Delphi Method and Pilot Test.

BACKGROUND: International guidelines recommend cardiac rehabilitation (CR) for secondary prevention of cardiovascular disease, however, it is underutilised and the quality of content and delivery varies widely. Quality indicators (QIs) for CR are used internationally to measure clinical practice performance, but are lacking in the Australian context. This study reports the development of QIs for minimum dataset (MDS) for CR and the results of a pilot test for feasibility and applicability in clinical practice in Australia. METHODS: A modified Delphi method was used to develop initial QIs which involved a consensus approach through a series of face-to-face and teleconference meetings of an expert multidisciplinary panel (n=8), supplemented by an environmental scan of the literature and a multi-site pilot test. RESULTS: Eight (8) QIs were proposed and sent to CR clinicians (n=250) electronically to rate importance, current data collection status, and feasibility of future collection. The top six of these QIs were selected with an additional two key performance indicators from the New South Wales (NSW) Ministry of Health and two QIs from international registers for a draft MDS. The pilot test in 16 sites (938 patient cases) demonstrated median performance of 93% (IQR 47.1-100%). All 10 QIs were retained and one further QI related to diabetes was added for a final draft MDS. CONCLUSIONS: The MDS of 11 QIs for CR provides an important foundation for collection of data to promote the quality of CR nationally and the opportunity to participate in international benchmarking.

Clinical Exercise Stress Testing in Adults (2014).

This position paper provide guidelines on the minimum requirements of both personnel and equipment for the safe performance of clinical exercise electrocardiography, and for the adequate interpretation and assessment of results. This document was originally developed by Professor Ben Freedman and members of the Rehabilitation, Exercise and Prevention Working Group in 1996. It has been recently reviewed by a Working Group chaired by Associate Professor David Colquhoun. The resulting, revised Statement was considered by the Continuing Education and Recertification Committee and ratified at the CSANZ Board meeting held on 1st August 2014.

Single-ring posterior left atrial (box) isolation results in a different mode of recurrence compared with wide antral pulmonary vein isolation on long-term follow-up: longer atrial fibrillation-free survival time but similar survival time free of any atrial arrhythmia.

BACKGROUND: Electric isolation of the pulmonary veins and posterior left atrium with a single ring of radiofrequency lesions (single-ring isolation [SRI]) may result in fewer atrial fibrillation (AF) recurrences than wide antral pulmonary vein isolation (wide antral isolation [WAI]) by abolishing extravenous AF triggers. The effect of mitral isthmus line (MIL) ablation on outcomes after SRI has not previously been assessed. METHODS AND RESULTS: We randomly assigned 220 consecutive patients (58 ± 10 years old; 82% men) with highly symptomatic AF (61% paroxysmal, 39% persistent/longstanding persistent) to undergo either SRI or WAI. Half of each cohort was also randomly allocated to have left lateral MIL ablation (2 ×2 factorial study design). Patients were followed clinically and with 7-day Holter studies for arrhythmia recurrences. The primary end points were recurrence of AF and organized atrial tachyarrhythmias. AF-free survival at 2 years was better after SRI (74% [95% CI, 65%-82%]) than WAI (61% [51%-70%]; P=0.031). Organized atrial tachyarrhythmia-free survival was similar after SRI and WAI (67% [57%-75%] ersus 64% [54%-72%], respectively, at 2 years; P=0.988). MIL ablation resulted in better 2-year organized atrial tachyarrhythmia-free survival (71% [62%-79%] versus 60% [50%-69%]; P=0.07), which approached statistical significance. Survival free of any atrial arrhythmia after one procedure was not significantly affected by isolation technique or MIL ablation. Conclusions- SRI resulted in fewer AF recurrences compared with WAI on long-term follow-up but did not reduce the recurrence of all atrial arrhythmias. MIL ablation may reduce organized atrial tachyarrhythmia recurrences. Clinical Trial Registration- http://www.anzctr.org.au; ACTRN12606000467538.

Early exercise stress testing is safe after primary percutaneous coronary intervention.

BACKGROUND: The optimal timing of exercise stress testing post primary percutaneous coronary intervention is uncertain with anecdotal evidence suggesting an increased risk of acute myocardial infarction and/or death if performed too early. This has translated into a delayed return to normal life activities following an acute myocardial infarction resulting in an increase in socio-economic burden. AIMS: We hypothesize that early (within 7 days of primary percutaneous coronary intervention) exercise stress testing is safe. METHODS: A prospective study of consecutive patients enrolled into the Cardiac Rehabilitation Program at a tertiary referral centre that underwent primary percutaneous coronary intervention, and who were able to perform a treadmill stress test were recruited. Timing of exercise stress testing was within 7 days post primary percutaneous coronary intervention and outcomes of death, acute myocardial infarction and other major adverse cardiac event were assessed 24 hours post exercise stress testing. RESULTS: Recruited patients (n=230) aged between 29 and 78 (mean age 56 ± 10 years) with 191 being males (83%) and 39 being females (17%). While 28 patients had a positive stress test (12.2%), there were no deaths, acute myocardial infarction or any other major adverse cardiac event within 24 hours of performing the exercise stress testing. Mean METS achieved were 8.1 ± 2.3. CONCLUSIONS: Early exercise stress testing after primary percutaneous coronary intervention appears safe.

Caring for others, but not themselves: implications for health care interventions in women with cardiovascular disease.

Cardiovascular disease is the largest killer of women internationally and women often suffer inferior outcomes following an acute cardiac event as compared to men. A gendered approach to investigating cardiovascular disease in women incorporates the unique social, cultural, and economic circumstances that being a woman brings to the health encounter. The multiple roles enacted by many women may be important factors in this health discrepancy. In order to more fully understand the impact of the roles of women on health, a questionnaire was administered to participants of the Heart Awareness for Women group cardiac rehabilitation program which assessed women's role perceptions followed by discussions. We found that caregiving can be both positive and negative. It gives a sense of purpose, meaning, and community connection as well as burden and conflict. Emphasis must be placed on promoting strategies in women to achieve a balance between caregiving responsibilities and prioritisation of cardiovascular health.

Correlation between a self-administered walk test and a standardised Six Minute Walk Test in adults.

This study was undertaken to assess the correlation between a self-administered, adapted Six Minute Walk Test (the Home-Heart-Walk) and the standard Six Minute Walk Test based on the American Thoracic Society guideline. A correlational study was conducted at a university campus in Sydney, Australia. Thirteen healthy volunteers underwent the Home-Heart-Walk and the standard Six Minute Walk Test on a single occasion. The distance that participants walked during the two tests was assessed using Pearson's correlation. The correlation between the Home-Heart-Walk and the Six Minute Walk Test distance was 0.81. The Home-Heart-Walk distance was highly correlated to the standard Six Minute Walk Test distance in this study. This relationship provides confidence for further research in populations to facilitate monitoring and evaluation.

An intervention to promote physical activity and self-management in people with stable chronic heart failure The Home-Heart-Walk study: study protocol for a randomized controlled trial.

BACKGROUND: Chronic heart failure (CHF) is a chronic debilitating condition with economic consequences, mostly because of frequent hospitalisations. Physical activity and adequate self-management capacity are important risk reduction strategies in the management of CHF. The Home-Heart-Walk is a self-monitoring intervention. This model of intervention has adapted the 6-minute walk test as a home-based activity that is self-administered and can be used for monitoring physical functional capacity in people with CHF. The aim of the Home-Heart-Walk program is to promote adherence to physical activity recommendations and improving self-management in people with CHF. METHODS/DESIGN: A randomised controlled trial is being conducted in English speaking people with CHF in four hospitals in Sydney, Australia. Individuals diagnosed with CHF, in New York Heart Association Functional Class II or III, with a previous admission to hospital for CHF are eligible to participate. Based on a previous CHF study and a loss to follow-up of 10%, 166 participants are required to be able to detect a 12-point difference in the study primary endpoint (SF-36 physical function domain).All enrolled participant receive an information session with a cardiovascular nurse. This information session covers key self-management components of CHF: daily weight; diet (salt reduction); medication adherence; and physical activity. Participants are randomised to either intervention or control group through the study randomisation centre after baseline questionnaires and assessment are completed. For people in the intervention group, the research nurse also explains the weekly Home-Heart-Walk protocol. All participants receive monthly phone calls from a research coordinator for six months, and outcome measures are conducted at one, three and six months. The primary outcome of the trial is the physical functioning domain of quality of life, measured by the physical functioning subscale of the Medical Outcome Study Short Form -36. Secondary outcomes include physical functional capacity measured by the standard six minute walk test, self-management capacity, health related quality of life measured by Medical Outcome Study Short Form -36 and Minnesota Living With Heart Failure Questionnaire, self-efficacy and self-care behaviour. DISCUSSION: A self-monitoring intervention that can improve individual's exercise self-efficacy, self-management capacity could have potential significance in improving the management of people with chronic heart failure in community settings.

Assessment of a self-administered adapted 6-minute walk test.

PURPOSE: This study assessed the reliability and viability of the Home-Heart-Walk (HHW) test, adapting a standardized 6-minute walk test protocol for self-administration. METHODS: Twenty-nine volunteers with documented coronary heart disease (CHD) undertook a structured 7-day program using the HHW. RESULTS: The intervention was well received by participants. The intraclass correlation coefficient of the test distance over 7 days was 0.98, and the correlations between investigator and participant measures were high (r = 0.99 for day 1 [first test], r = 0.99 for day 1 [second test], and r = 0.99 on day 7). CONCLUSION: These data demonstrate the potential of the HHW as a tool to promote and monitor physical activity in community-based settings. These observations require further investigation and testing in other populations.
