Heart failureLong-Term Effects of a Group-Based High-Intensity Aerobic Interval-Training Program in Patients With Chronic Heart Failure
Section snippets
Methods
The study population was obtained by screening all patients with CHF who were referred to the heart failure outpatient clinics at Ullevaal University Hospital and Lovisenberg Hospital (both in Oslo, Norway) during a 2.5-year period. Ninety-five patients were candidates for inclusion in the study, but 15 patients withdrew consent for various reasons. A study flow diagram is presented in Figure 1. The study was a prospective randomized controlled trial. The patients were randomized to either the
Results
At baseline, there were no significant differences in demographic data; time between time 1, time 2, and time 3; or medical treatment (Table 1). Medical treatment did not change during the intervention period, except for alterations in diuretic dosages (as is normal in clinical practice) and temporary medication changes during hospitalization. No events occurred during the exercise training. Of the 76 patients who completed the tests after the intervention period, 72 returned for evaluation 1
Discussion
This study is, to our knowledge, the first to document long-term effects on functional capacity and the quality of life in patients with CHF using a novel group-based, high-intensity aerobic interval training program. Our main hypothesis in this trial was confirmed.
Previous studies have been generally concordant in demonstrating an increase in functional capacity after short-term exercise training, but few comparable studies have evaluated whether patients with CHF continue to carry out

Impact of Exercise Rehabilitation on Exercise Capacity and Quality-of-Life in Heart Failure: Individual Participant Meta-Analysis
2019, Journal of the American College of CardiologyCitation Excerpt :For the HRQoL analysis, 9 trials (including 10 comparator groups) provided data for 3,000 patients (1,496 ExCR, 1,504 control) with a median follow-up of 33 weeks (24,34,35,38–43). For the exercise capacity analysis, 13 trials (14 comparator groups) provided 3,332 patients (1,662 ExCR, 1,670 control) with a median follow-up of 26 weeks (24,32–43).

The effectiveness of psychological interventions on self-care, psychological and health outcomes in patients with chronic heart failure—A systematic review and meta-analysis
2018, International Journal of Nursing StudiesCitation Excerpt :Therefore, intervention to promote patients’ self-care is of great clinical importance to improve treatment effectiveness and mitigate the negative impact of CHF. Traditionally, healthcare providers have provided information-based education with a focus on the value of pharmacological care and lifestyle-modification interventions (Austin et al., 2008; Dracup et al., 2007; Nilsson et al., 2008; O’Connor et al., 2009; Yu and Thompson, 2008). Most of this education is provided as part of the discharge instructions and/or as part of structured cardiac rehabilitation programs (Boren et al., 2009).

2016, International Journal of CardiologyEffect of continuous and interval aerobic exercise training on baroreflex sensitivity in heart failure
2016, Autonomic Neuroscience: Basic and ClinicalCitation Excerpt :Continuous AET is well known to reduce sympathetic nerve activity, prevent left ventricular remodeling, and increase BrS in clinical (Laterza et al., 2007; Martinez et al., 2011; Haykowsky et al., 2007a; Hambrecht et al., 2000) and experimental (Gao et al., 2007; Mousa et al., 2008; Liu et al., 2002) studies involving ischemic dilated cardiomyopathy. Recently, to overload the physiological system and stimulate greater adaptations (Stuckey et al., 2011), interval AET has been increasingly prescribed to HF patients (Wisloff et al., 2007; Nilsson et al., 2008). Interval AET consists of alternating periods of greater and lower intensity within an exercise session, whilst continuous AET is characterized by constant submaximal power output and O2 consumption throughout the entire session.
