AB  - OBJECTIVE: To analyze respiratory muscle strength of patients with heart failure 
      (HF) and correlate with functional capacity. METHODS: This cross-sectional study 
      involved patients with compensated HF of both sexes, aged above 18 years. 
      Respiratory muscle strength was assessed by measuring maximum inspiratory (MIP) 
      and expiratory pressures (MEP) using a manovacuometer. Patients were randomized 
      into two groups to assess functional capacity: six-minute walk test (6MWT) and 
      incremental shuttle walk test (ISWT). RESULTS: Forty-eight patients were 
      evaluated (23 from 6MWT and 25 from ISWT group). Most were male (67.8%), with 
      mean age of 62.3 years and left ventricular ejection fraction of 40.8%. Mean 
      predicted values of MIP [81.2% (74.7-87.8%)] and MEP [95.6% (88.2-103.0%)] did 
      not indicate respiratory muscle weakness. The higher the New York Heart 
      Association (NYHA) functional class, the lower the MIP (p = .011) and MEP 
      (p = .016) values. Physically active patients presented higher respiratory muscle 
      strength than those sedentary (MIP: 104.5 vs. 71.9 cmH(2)O, p < .001; MEP: 120.0 
      vs. 91.1 cmH(2)O, p = .004). Functional capacity was impaired [6MWT: 416.0 m 
      (372.8-459.3 m); ISWT: 304 m (263.4-344.9 m)], and distance covered in the ISWT 
      was shorter than 6MWT group (p < .001). Distance covered in the ISWT group 
      presented a moderate positive correlation with MIP (r = 0.45; p = .022) and MEP 
      (r = 0.41; p = .041). CONCLUSION: Most patients with HF presented respiratory 
      muscle strength close to predicted values; however, sedentary patients and those 
      with high NYHA functional class, showed reduced MIP and MEP. Functional capacity 
      was reduced, and MIP and MEP correlated with distance covered in the ISWT.
