      disease. Comparison of thoracic bioimpedance, thermodilution and 
      cineventriculography].
PG  - 203-9
AB  - Aim of the study was to verify the reliability of thoracic bioimpedance 
      cardiography (TEB) in detection, non-invasively, cardiac index (IC) and ejection 
      fraction (FE), compared to simultaneous evaluation by invasive thermodilution 
      (TD) in 39 patients with acute myocardial infarction in Killip class I-II (group 
      I), and by cineventriculography (CVG) in 26 patients with chronic coronary artery 
      disease in NYHA class I-II (group II). In order to define the reproducibility of 
      TEB values, in the latter patients, the above mentioned parameters were evaluated 
      6 times more, running the first evaluation. The statistical analysis was 
      performed by the linear regression test and the Student's "t" test and by the 
      test of variance for the reproducibility evaluation. Results (mean +/- SD) were 
      as follows: group I: TEB-IC 2.89 +/- 0.63; TD-IC 2.83 +/- 0.56 (1/min/m2); r = 
      0.68; p < 0.01. Group II: TEB-IC 2.88 +/- 0.71; CVG-IC 3.48 +/- 0.66; r = 0.77; p 
      < 0.001; TEB-FE 57.7 +/- 6.8%; CVG-FE 58.1 +/- 13.7%; r = 0.40; p = ns. Results 
      of the reproducibility referred to the 6 measurements (mean +/- SD) were the 
      follows: TEB-IC (1/min/m2) (1) 2.83 +/- 0.76; (2) 2.85 +/- 0.73; (3) 2.8 +/- 
      0.79; (4) 2.83 +/- 0.71; (5) 2.87 +/- 0.81; (6) 2.88 +/- 0.8, p = ns, the 
      variability was assesses within +/- 9.3%. TEB-FE (%): (1) 56.7 +/- 6.2; (2) 55.8 
      +/- 5; (3) 57.1 +/- 5.5; (4) 56.1 +/- 6.1; (5) 55.4 +/- 5.8; (6) 57.3 +/- 6.3, p 
      = ns; the variability was assessed within +/- 9.1%. The analysis of the results 
      showed a good correlation in the IC detection among TEB and the compared 
      techniques, conversely TEB evaluation of FE appear of poor values in this kind of 
      patients. Relatively to the results of the reproducibility this unquestionable 
      characteristic of TEB was demonstrated.
