Influence of Inspiratory Muscle Weakness on Inspiratory Muscle Training Responses in Chronic Heart Failure Patients: A Systematic Review and Meta-Analysis


“To determine whether the impact of inspiratory muscle weakness on inspiratory muscle training (IMT) affects inspiratory function and exercise capacity in chronic heart failure (CHF) patients.”


“The results emphasize the importance of evaluating the inspiratory muscles to identify patients with CHF and inspiratory muscle weakness; subgroup that showed better results after IMT.”

Combined aerobic/IMT vs. aerobic training in patients with chronic heart failure

This article published in the European Journal of Heart Failure was published online in March 2014.


Combined aerobic/inspiratory muscle training vs. aerobic training in patients with chronic heart failure.


Vent-HeFT is a multicentre randomized trial designed to investigate the potential additive benefits of inspiratory muscle training (IMT) on aerobic training (AT) in patients with chronic heart failure (CHF).”


“Forty-three Chronic Heart Failure (CHF) patients were randomized to an Aerobic Training/Inspiratory Muscle Training (AT/IMT) group or to an AT/SHAM group in a 12-week exercise programme. Aerobic Training involved 45 min of ergometer training at 70–80% of maximum heart rate, three times a week for both groups. In the AT/IMT group, Inspiratory Muscle Training was performed at 60% of sustained maximal inspiratory pressure (SPImax) while in the AT/SHAM group it was performed at 10% of SPImax, using a computer biofeedback trainer for 30 min, three times a week.”


“This randomized multicentre study demonstrates that Inspiratory Muscle Training (IMT) combined with aerobic training provides additional benefits in functional and serum biomarkers in patients with moderate Chronic Heart Failure. These findings advocate for application of IMT in cardiac rehabilitation programmes.”

POWERbreathe, Exercise Training & Long Term Management of Heart Failure Patients

On 19th September POWERbreathe friend and distributor in Switzerland, Health MG, attended this 3-day training workshop on Rehabilitation and Long Term Management of Heart Failure Patients, at University Hospital, Switzerland.

Regular physical exercise for patients with heart failure is recommended in the guidelines of the European Society of Cardiology as it could ultimately lead to positive changes in myocardial function, symptoms, functional capacity and probably survival. But physical activity is poorly implemented in daily clinical practice.

The aim of the course was to demonstrate the art of exercise training and secondary prevention as well as the interplay between key elements of long term management of heart failure patients.

The workshop was aimed at cardiac rehab physicians, heart failure specialists, cardiologists and GP’s, physiotherapists, sports scientists and nurses and included many aspects of exercise training and testing, including POWERbreathe respiratory muscle training.

The workshop summarised the most current evidence of the benefits of exercise training in patients with heart failure, with practical advice for long-term management, assessment of exercise capacity and the application of different exercise modalities.

POWERbreathe respiratory muscle training has been used as a stand-alone therapy and in cardiac rehabilitation in patients with heart failure and heart disease. Because patients with chronic heart failure (CHF) experience a restrictive pattern of lung function due to pulmonary hypertension, their lung ‘stiffness’ increases the load on their respiratory muscles and makes a significant contribution to their breathlessness. Respiratory muscle training has been shown to successfully increase inspiratory strength and endurance, alleviate breathlessness (dyspnea) and improve functional status in chronic heart failure. POWERbreathe training will only provide a very low cardiovascular strain, making it suitable for the most physically compromised patients and those who’re too ill for rehabilitation.
