Key result
High-intensity inspiratory muscle training improves exercise capacity and inspiratory strength in HFrEF versus low-intensity controls.
Why the study?
The optimal intensity of inspiratory muscle training to improve exercise capacity and inspiratory muscle strength in HFrEF patients remains unclear.
Does high-intensity inspiratory muscle training improve exercise capacity and inspiratory muscle strength in patients with heart failure with reduced ejection fraction?
Population
Patients with heart failure with reduced ejection fraction
Comparison
High-intensity IMT vs low-intensity IMT or sham-IMT
Design
Systematic review and meta-analysis of randomized controlled trials

May support adding high-intensity inspiratory muscle training to HFrEF exercise programs; reinforces prior trial evidence for this adjunctive approach.
Meta-Analysis
Does high-intensity inspiratory muscle training improve exercise capacity and inspiratory muscle strength in patients with heart failure with reduced ejection fraction?
High-intensity inspiratory muscle training appears to be a useful strategy for improving exercise capacity and inspiratory muscle strength in patients with HFrEF.
Neto et al. (2018) conducted a meta-analysis in Heart failure with reduced ejection fraction (HFrEF). High-intensity inspiratory muscle training (HIIMT) vs. Low-intensity IMT or sham-IMT was evaluated on Exercise capacity and inspiratory muscle strength. High-intensity inspiratory muscle training appears to improve exercise capacity and inspiratory muscle strength in patients with HFrEF (quantitative results omitted from abstract).
