Key result
Inspiratory muscle training improved maximum inspiratory mouth pressure by a mean of 25.4 cmH2O (P=0.04) but did not significantly improve exercise tolerance or quality of life.

Does domiciliary inspiratory muscle training improve exercise tolerance or quality of life in patients with stable chronic heart failure?
Mean Difference: 25.4
p-value: p=0.04
Inspiratory muscle training at 30% of maximum pressure increases inspiratory muscle strength but does not translate to improved exercise tolerance or quality of life in patients with stable chronic heart failure.
Peter Johnson (1998) conducted an RCT in stable chronic heart failure (n=18). Inspiratory muscle training vs. Sham training at 15% of maximum inspiratory mouth pressure was evaluated on Maximum inspiratory mouth pressure (MD 25.4, p=0.04). Inspiratory muscle training improved maximum inspiratory mouth pressure by a mean of 25.4 cmH2O (P=0.04) but did not significantly improve exercise tolerance or quality of life.
