The role of maximal inspiratory pressure on functional performance in adults with heart failure.

ABSTRACT:

Background

Exercise intolerance is common among adults with heart failure (HF) and is a strong prognostic indicator. We examined maximal inspiratory pressure (MIP) as an indicator of maximal and submaximal exercise capacity in older HF patients.

Methods

Fifty-one patients age ≥ 50 years with HF underwent MIP testing via the PrO₂ device. Peak oxygen uptake (VO₂), 6 min walk distance (6MWD), 30 s sit-to-stand test (STS), gait speed (GS), grip strength and lower extremity muscle strength [one-repetition maximum (1RM)] were measured. Correlation and exploratory multiple regression analyses investigated relationships between MIP, left ventricular ejection fraction (LVEF), age, body mass index (BMI) and physical function. MIP was then stratified by median (64
