Abstract/OtherAbstract:
INTRODUCTION: Inspiratory muscle training (IMT) offers an alternative to exercise training (ExT) in the most severely deconditioned heart failure patients who are unable to exercise. We conducted a meta-analysis to determine magnitude of change in peak VO(2), six minute walk distance (6MWD), Quality of Life measured by the Minnesota Living with Heart Failure Questionnaire (MLWHFQ), maximal inspiratory pressure (PI max) and ventilatory equivalent for carbon dioxide (V(E)/VCO(2) slope) with IMT. METHODS: A systematic search was conducted of randomized, controlled trials of IMT therapy in CHF patients using Medline (Ovid) (1950-February 2012), Embase.com (1974-February 2012), Cochrane Central Register of Controlled Trials and CINAHL (1981-February 2012). The search strategy included a mix of MeSH and free text terms for the key concepts heart failure, inspiratory or respiratory muscle training, exercise training RESULTS: The eleven included studies contained data on 287 participants: 148 IMT participants and 139 sham or sedentary control. Compared to control groups, CHF patients undergoing IMT showed a significant improvement in peak VO(2) (+1.83ml kg(-1) min(-1), 95% C.I. 1.33 to 2.32ml kg(-1) min(-1), p<0.00001); 6MWD (+34.35m, 95% C.I. 22.45 to 46.24m, p<0.00001); MLWHFQ (-12.25, 95% C.I. -17.08 to -7.43, p<0.00001); PI(max) (+20.01, 95% C.I. 13.96 to 26.06, p<0.00001); and V(E)/VCO(2) slope (-2.28, 95% C.I. -3.25 to -1.30, p<0.00001). CONCLUSIONS: IMT improves cardio-respiratory fitness and quality of life to a similar magnitude to conventional exercise training and may provide an initial alternative to the more severely de-conditioned CHF patients who may then transition to conventional ExT.
