OBJECTIVE: 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.
DATA SOURCES: Electronic
searches were performed using the Cumulative Index to Nursing and Allied Health
Literature, Cochrane Central Register of Controlled Trials, Cochrane Systematic
Review, Embase, MEDLINE, and Physiotherapy Evidence Database (PEDro) databases up
to August 2013. STUDY SELECTION: Articles were included if participants had CHF
and were >18 years old; the design was a randomized controlled trial;
intervention was IMT; measurements were of inspiratory muscle function or
exercise capacity; and the articles were published in English, Portuguese, or
Spanish. Of the 1455 articles identified in the database searches, 9 studies met
the inclusion criteria. DATA EXTRACTION: Two independent reviewers selected and
extracted information from articles and assessed the quality of the studies using
the PEDro scale. The 2 reviewers discussed disagreements until consensus was
achieved. DATA SYNTHESIS: Meta-analyses compared IMT with controls/sham for
maximal inspiratory pressure, sustained maximal inspiratory pressure, 6-minute
walk distance, peak oxygen consumption, and minute ventilation after IMT.
Subgroup analyses compared those with and without muscle weakness. CHF with
inspiratory muscle weakness showed greater gains in the 6-minute walk distance
and peak oxygen consumption compared with those with normative maximal
inspiratory pressure. The mean quality analysis score was 7.1, and scores ranged
from 6 to 10. CONCLUSIONS: 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.
