Abstract: Arterial baroreflex control of muscle sympathetic nerve activity (ABRMSNA) is impaired in chronic systolic heart failure (CHF). The purpose of the study was to test the hypothesis that exercise training would improve the gain and reduce the time delay of ABRMSNA in CHF patients. Twenty-six CHF patients, New York Heart Association Functional Class II-III, EF ≤ 40%, peak V̇o2 ≤ 20 ml·kg(-1)·min(-1) were divided into two groups: untrained (UT, n = 13, 57 ± 3 years) and exercise trained (ET, n = 13, 49 ± 3 years).… Show more

“…26,27) In addition, exercise training improved the gain and reduced the time delay of arterial baroreflex control of muscle sympathetic nerve activity in HF patients. 28) Arterial stiffness significantly decreased over a 20-week CR program in patients with established IHD. 29) Thus, the mechanism of the improvement of VVV in BP may involve a reduction of atrial stiffness and excessive sympathetic nerve activity and regulation of baroreflex sensitivity, although we did not analyze these functions in this study.…”

“…Aerobic exercise has long been recognized to improve autonomic balance, by both central and peripheral mechanisms (Billman et al 2015;Haack & Zucker, 2015). In humans with heart failure, ischaemic cardiomyopathy, diabetes and other diseases where autonomic imbalance is known to occur, aerobic exercise is known to improve cardiac autonomic indices (Gordon et al 1997;Laterza et al 2007;Spierer et al 2007;Kleiber et al 2008;Mousa et al 2008;El Mhandi et al 2011;Rodrigues et al 2012Rodrigues et al , 2014Zheng et al 2012;Kaikkonen et al 2014;Groehs et al 2015;Masson et al 2015;Sa et al 2016). As exercise has been covered in an accompanying White Paper, we will not focus on it further.…”

“…Moreover, a reduction after training of arteriovenous O 2 difference with an increase in cardiac output at peak exercise is frequent and it is suggestive of blood flow redistribution after workout. 44 In systolic HF patients, the effects of exercise training on neurovascular control and skeletal myopathy, 45 on the mechanisms of improving skeletal muscle O 2 transport and utilization, 46 and on the prevention of the deterioration in the arterial baroreflex control and sympathetic nerve 47 were recently reviewed. Esposito et al 48 demonstrated in HF muscles not only perfusive but also diffusive oxygen impairment as a new possible target of exercise training.…”
