Gore S, Khanna H, Kumar A. Effects of Comprehensive Outpatient Cardiac Rehabilitation on Exercise Capacity, Functional Status, and Quality of Life in People With Heart Failure: A Systematic Review and Meta-Analysis. Phys Ther 2023; 103:pzad119. [PMID: 37658777 PMCID: PMC10630615 DOI: 10.1093/ptj/pzad119] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 04/20/2023] [Accepted: 07/02/2023] [Indexed: 09/05/2023]
Abstract
PURPOSE The purpose of this study was to systematically review and conduct a meta-analysis to examine the impact of comprehensive outpatient cardiac rehabilitation on exercise capacity, functional status, and quality of life in patients with heart failure. METHODS PubMed, Embase, and CINAHL were searched using keywords and MeSH terms on heart failure and cardiac rehabilitation. Randomized clinical trials published in English using outpatient exercise-based cardiac rehabilitation in patients with heart failure were included. The Grading of Recommendations Assessment, Development, and Evaluation was utilized for quality appraisal. Pooled estimates were computed using standardized mean differences (SMDs) and 95% CIs. Primary outcomes were functional status (6-minute walk distance, quality of life, exercise capacity using peak oxygen consumption, muscle strength, and endurance). RESULTS Eleven randomized controlled trials including 1523 participants ranging from 45 to 80 years old and an intervention duration ranging from 2 to 26 weeks were analyzed. Pooled results indicated significant improvements with comprehensive cardiac rehabilitation on 6-minute walk distance (SMD = 0.30; 95% CI = 0.06 to 0.54) and oxygen consumption (SMD = 0.23; 95% CI = 0.06 to 0.40). However, there was no additional benefit for the quality of life beyond that seen in the comparison groups. CONCLUSION Results of this study suggest that comprehensive outpatient cardiac rehabilitation is associated with significantly better clinical outcomes than single-component exercise programs in cardiac rehabilitation settings, multicomponent exercise in noncardiac rehabilitation settings, or no exercise. IMPACT Heart failure is significantly associated with an increased risk of poor exercise tolerance. Despite the proven benefit of cardiac rehabilitation on exercise tolerance and physical activities from individual randomized clinical trials, questions regarding its impact on clinical outcomes such as exercise capacity, functional status, and quality of life remain inadequate. This systematic review and meta-analysis provides strong evidence supporting comprehensive outpatient cardiac rehabilitation for improving clinical outcomes in heart failure.

Arq Bras Cardiol 2023; 120:e20220799. [PMID: 37703105 PMCID: PMC10519353 DOI: 10.36660/abc.20220799] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 05/30/2023] [Accepted: 06/14/2023] [Indexed: 09/15/2023] Open
Abstract
BACKGROUND Following ST-segment elevation myocardial infarction (STEMI), patients with cardiac dysfunction have limitations in performing physical activity. Right ventricular (RV) function is a determinant in improving functional capacity, and cardiac rehabilitation (CR) is essential for this patient cohort. OBJECTIVE To evaluate the association of RV function with exercise tolerance after a CR program in patients with STEMI. METHODS Retrospective cohort study in patients with STEMI from January to December 2019. They underwent an echocardiographic assessment of RV function before a 16-session CR program. A cardiopulmonary exercise (CPX) testing was performed before and after the CR program. We analyzed whether RV function measured before CR was significantly associated with exercise tolerance before and after the CR program and the degree of improvement. Comorbidity, demographic and anatomic variables were documented. A p-value < 0.05 was considered statistically significant. RESULTS A total of 109 patients were included. Of all, 3.7% had global RV dysfunction, 10.1% had radial RV dysfunction, and 11% had longitudinal RV dysfunction. An association between radial or longitudinal RV dysfunction and the absence of improvement in cardiorespiratory fitness (> 1 peak VO2equivalents) was observed (p = 0.028, p = 0.008, respectively). A significant correlation was observed between longitudinal RV dysfunction with initial peak VO2equivalents (pVO2eq) (p = 0.046), final pVO2eq (p = 0.003), and difference in pVO2eq (p = 0.009). A correlation was also identified between global RV dysfunction and the initial pVO2eq (p = 0.045), final pVO2eq (p = 0.012), and difference in pVO2eq (p = 0.032). CONCLUSIONS RV dysfunction is associated with a lower capacity to exercise; CR programs can be extended or modified in these patients.

Abstract
Thirty years ago, patients with low ejection fraction (EF) have often been excluded from rehabilitation programs due to concern about possibility of sudden death or other adverse cardiovascular events during exercise sessions. Recent studies have highlighted the fact that cardiac rehabilitation could improve exercise capacity, cardiac function, and health-related quality of life in congestive heart failure patients. This encouraged us to write a review article and update our latest knowledge about the outcome of rehabilitation program in patients with severely depressed cardiac function. We were particularly interested in effect of cardiac rehabilitation on exercise capacity, quality of life, vascular effects, neuro-hormonal changes, and mortality. We also conducted a mini-systematic review and meta-analysis on randomized controlled trials comparing exercise training with usual care in patients with severely reduced left ventricular ejection fraction, for the mortality subsection to obtain precise estimates of overall treatment benefit on mortality. It is our privilege to submit our manuscript for possible publication in your prestigious journal.

Abstract
AIMS Abnormal left ventricular diastolic response to preload stress can be an early marker of heart failure (HF). The aim of this study was to assess clinical course in patients with HF with preserved ejection fraction (HFpEF) who underwent preload stress echocardiography. In the subgroup analysis, we assessed the prognosis of patients with unstable signs during preload stress classified by treatment strategies. METHODS AND RESULTS We prospectively conducted preload stress echocardiographic studies between January 2006 and December 2013 in 211 patients with HFpEF. Fifty-eight patients had abnormal diastolic reserve during preload stress (unstable impaired relaxation: unstable IR). Of 58 patients with unstable IR, 19 patients were assigned to additional therapy by increased or additional therapy and 39 patients were assigned to standard therapy. Composite outcomes were prespecified as the primary endpoint of death and hospitalization for deteriorating HF. During a median period of 6.9 years, 19 patients (33%) reached the composite outcome. Unstable group with standard therapy had significantly shorter event-free survival than stable group. Patients with uptitration of therapy had longer event-free survival than those with standard therapy group after adjustment of laboratory data (hazard ratio, 0.20, 95% confidence interval, 0.05-0.90; P = 0.036); the 10 year event-free survival in patients with and without uptitration of therapy was 93% and 51%, respectively (P = 0.023). CONCLUSIONS Patients with unstable sign had significantly shorter event-free survival than patients with stable sign. After additional therapy, the prognosis of patients with unstable signs improved. This technique may impact decision-making for improving their prognosis.

Abstract
Advanced age is widely recognized as a key risk factor for incident cardiovascular disease. The age-associated changes in cardiac properties alter the substrate on which cardiovascular disease is superimposed in various ways, and thus affect the development and manifestations of cardiovascular disease (CVD) in the elderly. However, it is still unclear whether age-related cardiac alteration is attributed to aging itself or whether it is secondary to other acquired cardiovascular risk factors. Understanding the association between aging and cardiac functional remodeling might provide insight into the pathogenesis of cardiovascular aging and may help inform possible preventive strategies for CVD in older individuals. Speckle-tracking echocardiography enables the objective and quantitative assessment of subtle myocardial alterations that are undetectable with conventional echocardiography, and has excellent feasibility and reproducibility. Left ventricular (LV) global longitudinal strain, a sensitive measure of LV systolic dysfunction, was found to be an independent risk factor for cardiovascular morbidity and mortality. More recently, deformation imaging has been employed to assess right ventricular (RV) and atrial performance, and impaired RV and atrial strain predict unfavorable outcomes in various clinical settings. This article reviews the association between aging and changes in myocardial strain values and describes future perspectives.

The Predictive Value of Right Ventricular Longitudinal Strain in Pulmonary Hypertension, Heart Failure, and Valvular Diseases. Front Cardiovasc Med 2021; 8:698158.

Abstract
Right ventricular (RV) systolic function has an important role in the prediction of adverse outcomes, including mortality, in a wide range of cardiovascular (CV) conditions. Because of complex RV geometry and load dependency of the RV functional parameters, conventional echocardiographic parameters such as RV fractional area change (FAC) and tricuspid annular plane systolic excursion (TAPSE), have limited prognostic power in a large number of patients. RV longitudinal strain overcame the majority of these limitations, as it is angle-independent, less load-dependent, highly reproducible, and measure regional myocardial deformation. It has a high predictive value in patients with pulmonary hypertension, heart failure, congenital heart disease, ischemic heart disease, pulmonary embolism, cardiomyopathies, and valvular disease. It enables detection of subclinical RV damage even when conventional parameters of RV systolic function are in the normal range. Even though cardiac magnetic resonance-derived RV longitudinal strain showed excellent predictive value, echocardiography-derived RV strain remains the method of choice for evaluation of RV mechanics primarily due to high availability. Despite a constantly growing body of evidence that support RV longitudinal strain evaluation in the majority of CV patients, its assessment has not become the part of the routine echocardiographic examination in the majority of echocardiographic laboratories. The aim of this clinical review was to summarize the current data about the predictive value of RV longitudinal strain in patients with pulmonary hypertension, heart failure and valvular heart diseases.
