“…Moreover, these trials do not examine the etiology of Chagas disease. In CHF populations with left ventricular systolic dysfunction, NMEE appears to produce the same benefits as conventional physical exercise training by increasing both exercise capacity and quality of life 8,9. NMEE appears to be particularly useful in patients unable to perform conventional exercises, such as those in NYHA functional class IV 10.…”

“…In general, aging is affected by environmental changes and can lead to various diseases (Kirkwood, 2005). In particular, the natural process of aging is among the most major risk factors that increase susceptibility to develop cardiovascular diseases (Dai et al, 2012), which often feature left ventricular hypertrophy (Dai and Rabinovitch, 2009), diastolic dysfunction (Bursi et al, 2006), valve degeneration (Karavidas et al, 2010), increased myocardial fibrosis (Olsen et al, 2005), and increased atrial fibrillation (Gerhard-Herman et al, 2017).…”

Aging is a risk factor for heart disease and heart failure, which result from a progressive impairment of cardiac functions, including stroke volume, cardiac output, blood flow, and oxygen consumption. Age-related cardiac dysfunction is associated with impaired cardiac structures, such as the loss of myocytes, structural remodeling, altered calcium (Ca2+) handling, and contractile dysfunction. However, the mechanism by which aging affects mitochondrial function in the heart is poorly understood. The purpose of this study was to determine the effects of aging on mitochondrial function in the rat heart. Male Fischer 344 rats were randomly assigned to very young sedentary (VYS, 1 month), young sedentary (YS, 4 months), middle-aged sedentary (MS, 10 months), and old sedentary (OS, 20 months) groups. mitochondrial complex protein levels and mitochondrial function (e.g., mitochondrial hydrogen peroxide (H2O2) emission and Ca2+ retention capacity) were analyzed in the left ventricle. Aging was associated with decreased levels of OXPHOS (oxidative phosphorylation) protein expression of complex I to IV in the function of the electron transport chain. Aging increased the mitochondrial H2O2 emitting potential in the heart. In contrast, mitochondrial Ca2+ retention capacity gradually decreased with age. These data demonstrate that aging impairs mitochondrial function in cardiac muscle, suggesting that mitochondrial dysfunction with aging may be a primary factor for aging-induced cardiac dysfunction in the heart.

“…[4][5][6] Electrical myostimulation (EMS) has shown potential beneficial effects in CHF patients, such as improvement of muscle function, exercise capacities, endothelial function and quality of life. [7][8][9][10][11][12][13][14][15][16] In CHF patients who are unable or unwilling to adhere to conventional exercise, low frequency quadricipital EMS has been proposed as an alternative treatment for ET and several studies reported a similar improvement with both methods. 17,18 But these studies are heterogeneous with different EMS protocols and have some limitations due to having small series of patients and monocentric data.…”

Background Exercise training as part of a comprehensive cardiac rehabilitation is recommended for patients with cardiac heart failure. It is a valuable method for the improvement of exercise tolerance. Some studies reported a similar improvement with quadricipital electrical myostimulation, but the effect of combined exercise training and electrical myostimulation in cardiac heart failure has not been yet evaluated in a large prospective multicentre study. Purpose The aim of this study was to determine whether the addition of low frequency electrical myostimulation to exercise training may improve exercise capacity and/or muscular strength in cardiac heart failure patients. Methods Ninety-one patients were included (mean age: 58 ± 9 years; New York Heart Association II/III: 52/48%, left ventricular ejection fraction: 30 ± 7%) in a prospective French study. The patients were randomised into two groups: 41 patients in exercise training and 50 in exercise training + electrical myostimulation. All patients underwent 20 exercise training sessions. In addition, in the exercise training + electrical myostimulation group, patients underwent 20 low frequency (10 Hz) quadricipital electrical myostimulation sessions. Each patient underwent a cardiopulmonary exercise test, a six-minute walk test, a muscular function evaluation and a quality of life questionnaire, before and at the end of the study. Results A significant improvement of exercise capacity (Δ peak oxygen uptake+15% in exercise training group and +14% in exercise training + electrical myostimulation group) and of quality of life was observed in both groups without statistically significant differences between the two groups. Mean creatine kinase level increased in the exercise training group whereas it remained stable in the combined group. Conclusions This prospective multicentre study shows that electrical myostimulation on top of exercise training does not demonstrate any significant additional improvement in exercise capacity in cardiac heart failure patients.
