TI  - Bioelectrical impedance and strength measurements in patients with heart failure: 
      comparison with functional class.
PG  - 412-8
AB  - OBJECTIVE: Patients with chronic heart failure (HF) develop important changes in 
      body composition. Nevertheless, the usual methods of body composition assessment 
      can be misleading in patients with HF because tissue hydration is altered. 
      Bioelectrical impedance vector analysis (BIVA) works without making any 
      assumption about constant soft tissue hydration. In this study, patients with HF 
      and systolic dysfunction (HFS) and preserved systolic function (HFPSF) underwent 
      a body composition evaluation by the BIVA method; the comparison was done between 
      New York Heart Association (NYHA) functional classes I-II and III-IV. METHODS: We 
      studied 243 patients with HF, 140 (101 in NYHA I-II and 39 in III-IV) with HFS 
      and 103 (67 in NYHA I-II and 36 in II-IV) with HFPSF. Whole-body bioelectrical 
      impedance was measured using BodyStat QuadScan 4000, which is tetrapolar and 
      multiple-frequency equipment. RESULTS: In both HF categories, reactance and phase 
      angle were significantly lower, the impedance ratio of 200 kHz to that at 5 kHz 
      was higher, and had significantly shorter and downsloping impedance vector in the 
      NYHA III-IV group compared with the NYHA I-II group by gender. CONCLUSION: 
      Bioelectrical impedance analysis allows an easier evaluation of body composition 
      and this might be particularly useful to stratify the severity of HF.
