Evidence-informed development of women-focused cardiac rehabilitation education.

BACKGROUND: Despite their differential risk factor burden, context and often different forms of heart disease, cardiac rehabilitation (CR) programs generally do not provide women with needed secondary prevention information specific to them. OBJECTIVE: to co-design evidence-informed, theory-based comprehensive women-focused education, building from Health e-University's Cardiac College for CR. METHODS: A multi-disciplinary, multi-stakeholder steering committee (N = 18) oversaw the four-phase development of the women-focused curriculum. Phase 1 involved a literature review on women's CR information needs and preferences, phase 2 a CR program needs assessment, phase 3 content development (including determining content and mode, assigning experts to create the content, plain language review and translation), and phase 4 will comprise evaluation and implementation. In phase 2, a focus group was conducted with Canadian CR providers; it was analyzed using Braun and Clarke's iterative approach. RESULTS: Nineteen providers participated in the focus group, with four themes emerging: current status of education, challenges to delivering women-focused education, delivery modes and topical resources. Results were consistent with those from our related global survey, supporting saturation of themes. Co-designed educational materials included 19 videos. These were organized across 5 webpages in English and French, specific to tests and treatments, exercise, diet, psychosocial well-being, and self-management. Twelve corresponding session slide decks with notes for clinicians were created, to support program delivery in CR flexibly. CONCLUSION: While further evaluation is underway, these open-access CR education resources will be disseminated for implementation, to support women in reducing their risk of cardiovascular sequelae.

Effect of hyperbaric oxygen treatment on patients with reduced left ventricular ejection fraction.

INTRODUCTION: Hyperbaric oxygen treatment (HBOT) is available to a wide spectrum of patients, many with significant co-morbidities. Considering its effects on cardiac physiology and reports of pulmonary oedema following exposure, concerns exist about the safety of patients with compromised cardiac function. Few studies have described adverse events occurring during HBOT and even fewer reports address events arising in the hours following HBOT. A relation between adverse events and cardiac function has not been established. As medical guidance is limited, we aimed to evaluate the risk for patients with reduced left ventricular ejection fraction (LVEF) receiving HBOT. METHODS: This retrospective chart review of patients receiving HBOT from April 2003 through December 2019 at our hospital was designed to describe clinical characteristics of patients and to identify adverse events during HBOT and within 24 hours after HBOT. Patients ≥ 40 years of age with a documented LVEF of ≤ 40% were included. Data are presented as mean (SD) [range] or counts, as appropriate. RESULTS: A total of 23 patients were included in the final analysis, 2 (1) [0-4] patients per year. Patients received 25 (19) [1-60] treatments. Two patients had an episode of acute decompensated heart failure possibly linked to HBOT. CONCLUSIONS: This study described the clinical characteristics of patients with reduced LVEF receiving HBOT and showed reassuring results, with a majority of patients with reduced LVEF tolerating HBOT well. Prospective research is required to more fully assess the risk.

Predictors of Exercise Maintenance 6 Months After Comprehensive Cardiac Rehabilitation.

PURPOSE: The objectives of this study were (1) to assess the effects of a comprehensive education intervention on maintenance of knowledge, exercise behavior, heart-healthy food intake, self-efficacy, and health literacy 6 mo after comprehensive cardiac rehabilitation (CR), and (2) to identify predictors of exercise maintenance 6 mo after comprehensive CR. METHODS: A prospective longitudinal study was conducted to test the effects of a structured educational curriculum in three CR programs in Canada. Participants completed surveys pre-, post-CR and 6 mo post-discharge to assess knowledge, heart-healthy food intake, self-efficacy, and health literacy. Exercise behavior was measured by number of steps/d using a pedometer. RESULTS: One hundred twenty participants completed the final survey. Increases in disease-related knowledge and self-efficacy, as well as behavior changes (increases in exercise and heart-healthy food intake), were achieved in comprehensive CR and sustained 6 mo post-program. Exercise maintenance was predicted by changes in heart-healthy food intake, self-efficacy, health literacy, and exercise-related knowledge. CONCLUSIONS: In this three-site study focusing on patient education for CR patients in Canada, the benefits of an education intervention in maintaining knowledge, exercise, healthy food intake, and self-efficacy were supported.

Acute glycaemic management before, during and after exercise for cardiac rehabilitation participants with diabetes mellitus: a joint statement of the British and Canadian Associations of Cardiovascular Prevention and Rehabilitation, the International Council for Cardiovascular Prevention and Rehabilitation and the British Association of Sport and Exercise Sciences.

Type 1 (T1) and type 2 (T2) diabetes mellitus (DM) are significant precursors and comorbidities to cardiovascular disease and prevalence of both types is still rising globally. Currently,~25% of participants (and rising) attending cardiac rehabilitation in Europe, North America and Australia have been reported to have DM (>90% have T2DM). While there is some debate over whether improving glycaemic control in those with heart disease can independently improve future cardiovascular health-related outcomes, for the individual patient whose blood glucose is well controlled, it can aid the exercise programme in being more efficacious. Good glycaemic management not only helps to mitigate the risk of acute glycaemic events during exercising, it also aids in achieving the requisite physiological and psycho-social aims of the exercise component of cardiac rehabilitation (CR). These benefits are strongly associated with effective behaviour change, including increased enjoyment, adherence and self-efficacy. It is known that CR participants with DM have lower uptake and adherence rates compared with those without DM. This expert statement provides CR practitioners with nine recommendations aimed to aid in the participant's improved blood glucose control before, during and after exercise so as to prevent the risk of glycaemic events that could mitigate their beneficial participation.

Effectiveness of an Education Intervention Among Cardiac Rehabilitation Patients in Canada: A Multi-Site Study.

BACKGROUND: Although patient education is considered a core component of cardiac rehabilitation (CR) programs, to our knowledge, no educational program designed for CR has been standardized in Canada. This absence of standardization may be due to a lack of reliable resources to educate these patients. The objective of this study was to assess the effectiveness of an education intervention in improving knowledge and health behaviours among CR patients in 3 sites in Canada. METHODS: CR patients were exposed to an evidence- and theoretically based comprehensive education intervention. Patients completed surveys assessing knowledge, physical activity, food intake, self-efficacy, and health literacy. All outcomes were assessed pre- and post-CR. Paired t tests were used to investigate variable changes between pre- and post-CR, Pearson correlation coefficients were used to determine the association between knowledge and behaviours, and linear regression models were computed to investigate differences in overall post-CR knowledge based on participant characteristics. RESULTS: A total of 252 patients consented to participate, of whom 158 (63.0%) completed post-CR assessments. There was a significant improvement in patients' overall knowledge pre- to post-CR, as well as in exercise, food intake, and self-efficacy (P < 0.05). Results showed a significant positive correlation between post-CR knowledge and food intake (r = 0.203; P = 0.01), self-efficacy (r = 0.201; P = 0.01), and health literacy (r = 0.241; P = 0.002). Education level (unstandardized beta = -2.511; P = 0.04) and pre-CR knowledge (unstandardized beta = 0.433; P < 0.001) were influential in changing post-CR knowledge. CONCLUSION: In this first-ever multi-site study focusing on patient education for CR patients in Canada, the benefits of an education intervention have been supported.

CONTEXTE: Bien que l'éducation du patient soit considérée comme un élément essentiel des programmes de réadaptation cardiaque (RC), il n'existe, à notre connaissance, aucun programme éducatif standardisé en RC au Canada. Cette absence de standardisation peut être attribuable à un manque de ressources fiables en matière d'éducation des patients. Cette étude visait à évaluer l'efficacité réelle d'une intervention éducative au regard de l'amélioration des connaissances et des comportements touchant la santé chez des patients en RC dans trois établissements au Canada. MÉTHODOLOGIE: Une intervention éducative globale fondée sur des données probantes et théoriques a été menée auprès de patients en RC. Les patients ont répondu à des questionnaires d'évaluation des connaissances, de l'activité physique, de l'apport alimentaire, de l'autoefficacité et de la littératie en matière de santé. Tous les résultats ont été évalués avant et après la RC. Des tests t pour échantillons appariés ont été utilisés pour étudier les changements touchant les variables évaluées avant et après la RC, des coefficients de corrélation de Pearson ont servi à déterminer l'association entre les connaissances et les comportements, et des modèles de régression linéaire ont été calculés pour étudier les différences dans les connaissances globales après la RC en fonction des caractéristiques des participants. RÉSULTATS: Au total, 252 patients ont accepté de participer; de ce nombre, 158 (63,0 %) ont pris part aux évaluations postérieures à la RC. Les connaissances globales des patients se sont améliorées de façon significative d'avant à après la RC, tout comme l'activité physique, l'apport alimentaire et l'autoefficacité (p < 0,05). Les résultats ont montré une corrélation positive significative entre les connaissances et l'apport alimentaire (r = 0,203; p = 0,01), l'autoefficacité (r = 0,201; p = 0,01) et la littératie en matière de santé (r = 0,241; p = 0,002) après la RC. Le niveau d'éducation (B = -2,511; p = 0,04) et les connaissances avant la RC (B = 0,433; p < 0,001) ont influé sur les changements touchant les connaissances après la RC. CONCLUSION: Cette toute première étude multicentrique axée sur l'éducation des patients en RC au Canada a permis de confirmer les avantages d'une intervention éducative.

Determinants of Improvement In Left Ventricular Diastolic Function Following a 1-Year Lifestyle Modification Program in Abdominally Obese Men with Features of the Metabolic Syndrome.

BACKGROUND: Abdominal obesity and presence of the metabolic syndrome (MetS) are associated with cardiac abnormalities. Among those, left ventricular diastolic dysfunction (LVDD) is the most frequently encountered in clinical practice. Few studies evaluated the reversibility of LVDD by an approach promoting lifestyle modifications in abdominally obese subjects with MetS. METHODS: We assessed the impact of a 1-year lifestyle modification program combining nutritional and physical activity counseling on LVDD and metabolic profile of abdominally obese men with MetS. Echocardiograms, oral glucose tolerance test, lipids profile, dual energy X-ray absorptiometry, computed tomography scans (visceral obesity assessment), heart rate variability (HRV), as well as maximal and submaximal exercise tests were performed in participants before and after a 1-year program combining healthy eating and a physical activity/exercise program. RESULTS: Fifty-one abdominally obese men participated in this study. At baseline, 86% of the participants had LVDD (n = 44). After the 1-year program, LVDD improved in 57% of participants (n = 29, P < 0.0001). All metabolic, adiposity, and exercise tolerance measures improved from baseline (P < 0.0001), but were not associated with improvement in LVDD. Participants who improved LVDD had better exercise performance at baseline. Exercise tolerance during the submaximal exercise test, parasympathetic cardiac autonomic activity, and fasting insulin predicted 50% of LVDD improvements. CONCLUSIONS: There was a significant improvement in LVDD after a 1-year lifestyle intervention program in abdominally obese men with MetS, such an improvement being associated with increased exercise tolerance, enhanced HRV, and reduced insulin levels.

Visceral/epicardial adiposity in nonobese and apparently healthy young adults: association with the cardiometabolic profile.

OBJECTIVE: We investigate associations of regional adipose tissues with cardiometabolic profile of nonobese and apparently healthy young adults. METHODS: Four hundred twenty-five nonobese and apparently healthy individuals were assessed for blood pressure and fasting lipid profile, blood glucose and adiponectin. Subcutaneous abdominal adipose tissue (SAT) and ectopic fat depots (visceral abdominal adipose tissue [VAT], epicardial adipose tissue [EAT] and hepatic fat fraction [HFF]) were quantified by magnetic resonance imaging. RESULTS: According to anthropometric measurements, blood pressure and blood markers, the population (18-35 years, 54% women) had a low cardiometabolic risk. Compared to women, men had more VAT, EAT and HFF, but less SAT. Regional adipose tissues were positively correlated with each other. VAT and EAT carried significant correlations with all markers of cardiometabolic risk, while SAT and HFF correlated variably with these markers. While taking into account age and gender, SAT, VAT and EAT were associated with most cardiometabolic markers, while HFF was only associated with total cholesterol/high-density lipoprotein ratio (TC/HDL-C) and triglycerides (TG). When comparing SAT, VAT and EAT head-to-head, VAT was the only adipose tissue location maintaining significant association with most markers of cardiometabolic risk. Greater VAT (≥50th percentile) was associated with a worse cardiometabolic profile, whether individuals were overweight or normal weight. CONCLUSION: Even in nonobese and apparently healthy young women and men, accumulation of ectopic visceral adiposity in general, and of VAT in particular, is associated with a worse cardiometabolic profile whether individuals were overweight or normal weight.
