TI  - [Assessment of diastolic function in Chagas' disease with pulsed doppler tissue 
      imaging].
PG  - 31-8
AB  - Diastolic function is involved early during the undetermined form of Chagas' 
      disease (Ch). Pulsed Doppler tissue imaging (DTI) is a new technique to evaluate 
      diastolic function recording myocardial velocities in the longitudinal axis. To 
      evaluate the relevance of DTI in patients with Ch, we studied, with Doppler and 
      echocardiography, 49 patients (average age 49 +/- 12 years) and 20 normal 
      subjects (average age 45 +/- 15 years) as a control group (C). Patients were 
      divided in four groups according to the pattern of their mitral and pulmonary 
      vein flows: Normal diastolic function (N), prolonged relaxation (PR), 
      pseudonormal (PN) and restrictive (R). Peak velocity of the E wave of the lateral 
      mitral annulus (Ea) was diminished in PR, PN, and R patients (0.11 +/- 0.02 m/s, 
      0.10 +/- 0.02 m/s and 0.12 +/- 0.06 m/s, respectively) as compared to group C 
      (0.18 +/- 0.07 m/s, p < 0.01) but not with respect to group N (0.15 +/- 0.03 m/s, 
      N.S.). In this latter group only peak E velocity of transmitral flow/Ea ratio was 
      useful to detect diastolic abnormalities as compared to group C (4.92 +/- 0.98 vs 
      4.14 +/- 1.26, p < 0.05). DTI was useful in the assessment of diastolic function 
      in Ch, including those patients in whom mitral and pulmonary vein flows were 
      normal.
