Scrutinio D, Guida P, Passantino A. Prognostic Value of 6-Minute Walk Test in Advanced Heart Failure With Reduced Ejection Fraction. Am J Cardiol 2023; 199:37-43. [PMID: 37245248 DOI: 10.1016/j.amjcard.2023.04.041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 04/13/2023] [Accepted: 04/30/2023] [Indexed: 05/30/2023]
Abstract
There is limited evidence regarding the prognostic value of the 6-minute walk test for patients with advanced heart failure (HF). Accordingly, we studied 260 patients presenting to inpatient cardiac rehabilitation (CR) with advanced HF. The primary outcome was 3-year all-cause mortality after discharge from CR. The association between 6-minute walk distance (6MWD) and the primary outcome was determined using the multivariable Cox regression analysis. To avoid collinearity, 6MWD at admission (6MWDadm) to CR and 6MWD at discharge (6MWDdisch) from CR were analyzed separately. At multivariable analysis, 4 baseline characteristics (age, ejection fraction, systolic blood pressure, and blood urea nitrogen) were identified as prognostic of the primary outcome (baseline risk model). After adjusting for the baseline risk model, the hazard ratios of 6MWDadm and 6MWDdisch modeled as per 50-m increase for the primary outcome were 0.92 (95% confidence interval [CI] 0.85 to 0.99, p = 0.035) and 0.93 (95% CI 0.88 to 0.99, p = -017), respectively. After adjusting for the Meta-analysis Global Group in Chronic Heart Failure (MAGGIC) score, the corresponding hazard ratios were 0.91 (95% CI 0.84 to 0.98, p = 0.017) and 0.93 (95% CI 0.88 to 0.99, p = 0.016). The addition of either 6MWDadm or 6MWDdisch to the baseline risk model or the MAGGIC score yielded a statistically significant increase in global chi-square and in the net proportion of survivors reclassified downward. In conclusion, our data suggest that the distance covered during a 6-minute walk test predicts survival and provides incremental prognostic information on the top of well-established prognostic factors and the MAGGIC risk score in advanced HF.

Abstract
Background Exercise training in heart failure (HF) is recommended but not routinely offered, because of logistic and safety-related reasons. In 2020, the German Society for Prevention&Rehabilitation and the German Society for Cardiology requested establishing dedicated “HF training groups.” Here, we aimed to implement and evaluate the feasibility and safety of one of the first HF training groups in Germany. Methods Twelve patients (three women) with symptomatic HF (NYHA class II/III) and an ejection fraction ≤ 45% participated and were offered weekly, physician-supervised exercise training for 1 year. Patients received a wrist-worn pedometer (M430 Polar) and underwent the following assessments at baseline and after 4, 8 and 12 months: cardiopulmonary exercise test, 6-min walk test, echocardiography (blinded reading), and quality of life assessment (Kansas City Cardiomyopathy Questionnaire, KCCQ). Results All patients (median age [quartiles] 64 [49; 64] years) completed the study and participated in 76% of the offered 36 training sessions. The pedometer was worn ≥ 1000 min per day over 86% of the time. No cardiovascular events occurred during training. Across 12 months, NT-proBNP dropped from 986 pg/ml [455; 1937] to 483 pg/ml [247; 2322], and LVEF increased from 36% [29;41] to 41% [32;46]%, (p for trend = 0.01). We observed no changes in exercise capacity except for a subtle increase in peak VO2% predicted, from 66.5 [49; 77] to 67 [52; 78]; p for trend = 0.03. The physical function and social limitation domains of the KCCQ improved from 60 [54; 82] to 71 [58; 95, and from 63 [39; 83] to 78 [64; 92]; p for trend = 0.04 and = 0.01, respectively. Positive trends were further seen for the clinical and overall summary scores. Conclusion This pilot study showed that the implementation of a supervised HF-exercise program is feasible, safe, and has the potential to improve both quality of life and surrogate markers of HF severity. This first exercise experiment should facilitate the design of risk-adopted training programs for patients with HF.

Abstract
Cardiac rehabilitation is defined as a multidisciplinary program that includes exercise training, cardiac risk factor modification, psychosocial assessment, and outcomes assessment. Exercise training and other components of cardiac rehabilitation (CR) are safe and beneficial and result in significant improvements in quality of life, functional capacity, exercise performance, and heart failure (HF)-related hospitalizations in patients with HF. Despite outcome benefits, cost-effectiveness, and strong practice guideline recommendations, CR remains underused. Clinicians, health care leaders, and payers should prioritize incorporating CR as part of the standard of care for patients with HF.

Abstract
Aging is characterized by heterogeneity, both in health and illness. Older adults with heart failure often have preserved ejection fraction and atypical and delayed clinical manifestations. After diagnosis of heart failure is established, a cause should be sought. The patient's comorbidities may provide clues. An elevated jugular venous pressure is the most reliable clinical sign of fluid volume overload and should be carefully evaluated. Left ventricular ejection fraction must be determined to assess prognosis and guide therapy. These 5 steps, namely, diagnosis, etiologic factor, fluid volume, ejection fraction, and therapy for heart failure may be memorized by mnemonic: DEFEAT-HF.

Abstract
In this review, we discuss the most recent forms of exercise training available to patients with cardiac disease and their comparison or their combination (or both) during short- and long-term (phase II and III) cardiac rehabilitation programs. Exercise training modalities to be discussed include inspiratory muscle training (IMT), resistance training (RT), continuous aerobic exercise training (CAET), and high-intensity interval training (HIIT). Particular emphasis is placed on HIIT compared or combined (or both) with other forms such as CAET or RT. For example, IMT combined with CAET was shown to be superior to CAET alone for improving functional capacity, ventilatory function, and quality of life in patients with chronic heart failure. Similarly, RT combined with CAET was shown to optimize benefits with respect to functional capacity, muscle function, and quality of life. Furthermore, in recent years, HIIT has emerged as an alternative or complementary (or both) exercise modality to CAET, providing equivalent if not superior benefits to conventional continuous aerobic training with respect to aerobic fitness, cardiovascular function, quality of life, efficiency, safety, tolerance, and exercise adherence in both short- and long-term training studies. Finally, short-interval HIIT was shown to be useful in the initiation and improvement phases of cardiac rehabilitation, whereas moderate- or longer-interval (or both) HIIT protocols appear to be more appropriate for the improvement and maintenance phases because of their high physiological stimulus. We now propose progressive models of exercise training (phases II-III) for patients with cardiac disease, including a more appropriate application of HIIT based on the scientific literature in the context of a multimodal cardiac rehabilitation program.

Abstract
AIM To explore the conceptual underpinnings of self-efficacy to address the barriers to participating in physical activity and propose a model of intervention. BACKGROUND The benefits of physical activity in reducing cardiovascular risk have led to evidence-based recommendations for patients with heart disease, including those with chronic heart failure. However, adherence to best practice recommendations is often suboptimal, particularly in those individuals who experience high symptom burden and feel less confident to undertake physical activity. Self-efficacy is the degree of confidence an individual has in his/her ability to perform behaviour under several specific circumstances. Four factors influence an individual's level of self-efficacy: (1) past performance, (2) vicarious experience, (3) verbal persuasion and (4) physiological arousal. DESIGN Discursive. METHODS Using the method of a discursive paper, this article seeks to explore the conceptual underpinnings of self-efficacy to address the barriers to participating in physical activity and proposes a model of intervention, the Home-Heart-Walk, to promote physical activity and monitor functional status. CONCLUSIONS Implementing effective interventions to promote physical activities require appreciation of factors impacting on behaviour change. Addressing concepts relating to self-efficacy in physical activity interventions may promote participation and adherence in the longer term. RELEVANCE TO CLINICAL PRACTICE The increasing burden of chronic disease and the emphasis on self-management strategies underscore the importance of promoting adherence to recommendations, such as physical activity.

Abstract
The pathophysiology of several conditions including heart failure is partly attributable to a failure of the cell energy metabolism. Studies have shown that exercise training (ET) improves quality of life (QOL) and is beneficial in terms of reduction of symptoms, mortality and duration of hospitalization. Increasingly, ET is now achieving acceptance as complimentary therapy in addition to routine clinical practice in patients with chronic heart failure (CHF). However, the mechanisms underlying the beneficial effects of ET are far less understood and need further evaluation. Evidence suggests that while CHF induces generalized metabolic energy depletion, ET largely enhances the overall function of the heart muscle. Hence, research efforts are now aiming to uncover why ET is beneficial as a complimentary treatment of CHF in the context of improving endothelial function and coronary perfusion, decreasing peripheral resistance, induction of cardiac and skeletal muscle cells remodeling, increasing oxygen uptake, substrate oxidation, and resistance to fatigue. Here we discuss the current evidence that suggest that there are beneficial effects of ET on cardiac and skeletal muscle cells oxidative metabolism and intracellular energy transfer in patients with CHF.

Abstract
The volume of literature attesting to the clinical benefits of exercise training in patients with stable chronic heart failure (CHF) is substantial. Training can improve symptoms and exercise capacity, as well as reducing morbidity, mortality, and rates of emergency hospitalization. These benefits are apparent in all patients with stable CHF, irrespective of age or sex, or the etiology or severity of heart failure. Training regimens for patients with stable, systolic CHF should form part of a comprehensive heart-failure support effort and are best delivered using supervised in-hospital exercise combined with some training at home or in a group setting in community centers. In this Review, the modes and intensity of exercise training, selection of patients, duration of training effects, and other clinical guidance for using this treatment option are discussed.

Abstract
OBJECTIVE To assess exercise capacity and left ventricular function using magnetic resonance imaging (MRI) among patients with chronic heart failure randomized to a residential rehabilitation programme at baseline and six years after participation. DESIGN Randomized controlled study. SETTING Residential cardiac rehabilitation centre and community hospital. INTERVENTION One month of intensive exercise and risk reduction therapy including educational sessions, a low-fat diet, and 2 hours of individually prescribed exercise daily. Control subjects received usual care. Subjects were evaluated at baseline, after completing the one-month residential programme and six years later. SUBJECTS From an original study group of 50, 16 patients (8 exercise, 8 controls) with chronic heart failure were alive and available for evaluation after six years. MAIN MEASURES Cardiopulmonary exercise test responses and ventricular size and function using MRI. RESULTS Peak Vo(2) was 20.0 and 12.4% higher after the rehabilitation programme and six years later, respectively, whereas minimal changes were observed among controls. Left ventricular mass and volumes tended to decrease among subjects in the exercise group, whereas left ventricular mass and volumes tended to increase among control subjects after six years. Ejection fraction increased approximately 20% in both groups. CONCLUSION Six years after participation in a concentrated residential rehabilitation programme, exercise capacity was preserved and no significant changes were observed in ventricular size or function. These findings provide further support for exercise rehabilitation in chronic heart failure.

Abstract
Objective: To investigate the effects of Nordic Walking training supplemental to a standard, early rehabilitation programme on exercise capacity and physical fitness in men after an acute coronary syndrome. Design: A controlled trial. Setting: Cardiac rehabilitation service of a provincial hospital. Subjects: Eighty men 2—3 weeks after an acute coronary syndrome, with good exercise tolerance. Interventions: Three-week, inpatient cardiac rehabilitation programme (control group) supplemented with Nordic Walking (Nordic Walking group), or with traditional walking training (walking training group). Main measures: Exercise capacity was assessed as peak energy cost (in metabolic equivalents) in symptom-limited treadmill exercise test, and physical fitness with the Fullerton Functional Fitness Test. Results: Exercise capacity after the rehabilitation programme was higher in the Nordic Walking group than in the control group (10.8 ± 1.8 versus 9.2 ± 2.2 metabolic equivalents, P =0.025). The improvement in exercise capacity in the Nordic Walking group was higher than in the control group (1.8 ± 1.5 versus 0.7 ± 1.4 metabolic equivalents, P =0.002). In contrast to the control group, the results of all components of the Fullerton test improved in the Nordic Walking and walking training groups. After the programme, lower body endurance, and dynamic balance were significantly better in the Nordic Walking group in comparison with the walking training and control groups, and upper body endurance was significantly better in the Nordic Walking and walking training groups than in the control group. Conclusions: Nordic Walking may improve exercise capacity, lower body endurance and coordination of movements in patients with good exercise tolerance participating in early, short-term rehabilitation after an acute coronary syndrome.

Abstract
Exercise training is increasingly recognized as a viable treatment option for patients with heart failure (HF). For exercise to be a maximally effective treatment, it is important that patients adhere to the exercise prescription. In this review, the current state of adherence monitoring and intervention in randomized HF trials will be summarized, along with recommendations for advancing understanding of adherence in this population. Barriers to exercise participation and strategies to enhance adherence to exercise-training programs will be explored. Finally, directions for future research on exercise adherence in HF patients will be provided.

Abstract
BACKGROUND The enhancement of circulating endothelial progenitor cells (EPCs) obtained by exercise training can be beneficial to patients with cardiac disease. Changes in the levels and differentiation of CD34(pos)/KDR(pos) EPCs, as well as the plasma concentration of vascular endothelial growth factor (VEGF) and stromal cell-derived factor (SDF)-1 EPC-mobilizing cytokines, were evaluated in patients with chronic heart failure after 8 weeks of supervised aerobic training (SAT) and 8 weeks of subsequent discontinued SAT (DSAT). METHODS AND RESULTS The levels of circulating EPC and EPC differentiation potential of 22 patients who underwent SAT were studied by fluorescence-activated cell sorter analysis and colony forming-unit assay, respectively. The plasma levels of VEGF and SDF-1 were measured by enzyme-linked immunosorbent assay. In response to SAT, the levels of both EPC and VEGF/SDF-1 markedly increased (P < .001 vs baseline) but returned to the baseline levels after DSAT. A similar change was observed with the EPC clonogenic potential, but on DSAT the baseline level was incompletely attained. CONCLUSIONS In response to SAT, patients with chronic heart failure show enhanced EPC levels and clonogenic potential that is mirrored by increased plasma VEGF and SDF-1 levels. DSAT can interfere with the maintenance of training-acquired VEGF/SDF-1-related EPC levels and clonogenic potential.

Abstract
Aging is characterized by heterogeneity, both in health and in disease. Older adults who have heart failure (HF) often have atypical and delayed clinical manifestations and many have diastolic HF. The assessment and management of HF in older adults may be simplified by a 5-step process called DEFEAT HF: (1) establish a clinical Diagnosis of HF; (2) establish an Etiology for HF, preferably in collaboration with a cardiologist; (3) determine Fluid status and achieve euvolemia; (4) determine left ventricular Ejection frAction; and (5) provide evidence-based Therapy.
