“…Moreover, in line with previous findings we observed an improvement in LVEF by 2 ± 5% at 3-month follow-up [50]. The effects on PWV were not observed in our study indicating no BP-dependent or BP-independent effects of SLOWB on large artery remodeling.…”

“…Recent reports documenting the effectiveness of SLOWB home training in improving oxygen saturation, cardiorespiratory capacity, functional performance, vagal activity, LVEF and reducing pulmonary pressure and breathlessness highlight the important role of breathing frequency in HF patients [23,25,26,28,29,[38][39][40].…”

“…Given the importance of psychological distress and poor QoL to the severity of HF, associated morbidity and mortality, hospital readmission, and duration of hospital stay [2,4,[18][19][20][21], interventions to specifically target potentiated reactivity to mental challenges, physical exertion [22], social aspects and associated QoL are likely to be of substantial clinical benefit. The feasibility and therapeutic effectiveness of the slow breathing (SLOWB) technique has been documented in chronic HF [23][24][25][26][27][28]. Very recently, it was documented that SLOWB home training improves clinical symptoms, physical and cardiorespiratory capacity, and vagal activity in patients with severe HF with reduced ejection fraction (HFrEF) irrespective of HF etiology [29].…”

Background: Previous studies have demonstrated therapeutic benefits of slow breathing (SLOWB) in chronic heart failure (HF) but its impact on cardiovascular reactivity in response to laboratory stressors remains unknown. Methods: Using device-guided breathing this study explored the acute and long-term effects of SLOWB on hemodynamic responses to handgrip, mental and cold pressor tests, and health-related quality of life (QoL) in stable HF patients with reduced ejection fraction (HFrEF) who had received all available optimal drug and device therapies. Blood pressure (BP) and heart rate (HR) were measured in 21 patients with HFrEF (23.9 ± 5.9%) at rest, during laboratory stressors, before and after acute SLOWB, and 12 weeks after SLOWB home training (30 min daily). Health-related QoL (MacNew questionaries) was assessed before and 12 weeks after SLOWB home training. Results: Resting BP significantly increased in response to three laboratory stressors. Pressor and cardiac changes during mental stress were greater than responses to the handgrip test (p < 0.05). Mental stress also produced a greater HR change than cold pressor test (p < 0.05). Both acute and long-term SLOWB significantly reduced BP and HR responses to mental stress (p < 0.05), but not to isometric and cold pressor tests. SLOWB improved scores of all domains of QoL (p < 0.05) at 12 weeks follow-up. Conclusions: These findings demonstrate that SLOWB reduces acute and chronic effects of cardiovascular reactivity to mental stress and improves various aspects of health-related QoL in patients with severe HFrEF. Whether stress reduction and psychological changes achieved with SLOWB may translate to improved outcomes in HFrEF warrants further exploration.

“…Some authors consider that VBE effectively improved quality of life, reduced symptoms associated with a variety of anxiety and depression [20,21]. VBE is also applied to treat cardiovascular complaints, such as primary hypertension [11,16], heart failure [19,22,23], arrhythmia [24],and so on. Kawecka-Jaszcz K et al [23] found that respiratory exercise combined with exercise rehabilitation for a period of 10 to 12 week in patients with chronic heart failure had a better effect on ejection fraction and 6-minute walk test, but this study failed to observe the functional changes of autonomic nervous function.…”

Abstract Background: At present, China has more than 11 million patients with stable coronary heart disease, becoming a major public health problem. The pathological changes of coronary heart disease can lead to dysfunction of cardiac autonomic nervous system, which increases the risk of complications such as malignant arrhythmia (ventricular flutter, ventricular fibrillation, etc.), heart rate, systolic blood pressure, and rate-pressure-product (RPP), which is highly correlated with myocardial oxygen consumption and indirectly reflects myocardial blood supply and oxygen consumption. Although the guidelines recommend that such patients take drugs to reduce heart rate and myocardial oxygen consumption, the clinical control of heart rate is still not ideal. Thus, in this trial, we will use voluntary breathing exercises as the strategy of exercise rehabilitation patients with Stable coronary artery disease（SCAD）, in order to increase the vagus nerve activity and/or reduce the sympathetic nervous activity, help maintain or rebuild the balance of plant nerve system, improve the time domain index of heart rate variability, reduce the burden on the heart, relieve patients' anxiety and other negative emotions. Methods: This is a 6 months single-blind, randomized controlled clinical trial that will be conducted in the First Affiliated Hospital of Soochow University. 140 patients who fill out the Informed Consent Form are registered and randomized 1:1 into the Voluntary Breathing Exercises（VBE）-based clinical trial monitoring group (n = 70) or the Routine follow-up group (n = 70). The VBE-based clinical trial monitoring group is given VBE training on the basis of conventional treatment and health education, while the control group received conventional health education and follow-up. The primary outcome will be measured heart rate variability(HRV) and rate-pressure product (RPP). Secondary outcomes will include changes in self-rating anxiety ccale (SAS), total cholesterol(TC),triglyceride(TG), high density lipoprotein (HDL-C),low density lipoprotein(LDL-C), weight and body mass index (BMI). Discussion: This trial will carry out scientific respiratory exercise for patients with stable coronary heart disease, which belongs to the category of active secondary prevention for patients, and changes from remedial to pre-protective. VBE is easy to operate, and is not limited by time and place. It is very important and meaningful to carry out VBE for patients with SCAD. This study will provide considerable evidence for further large-scale trials and alternative strategies for the rehabilitation nursing of patients with SCAD. Trial registration: This study is registered at Chinese Clinical Trials Registry.gov, ID:1900024043.Registered on 23 June 2019.
