[Assessment of diastolic function in Chagas' disease with pulsed doppler tissue imaging].

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).

[Assessment of diastolic function in Chagas disease with pulsed Doppler tissue imaging].

Diastolic function is early involved during the undetermined form of Chagas disease. Pulsed Doppler tissue imaging is a new technique to evaluate diastolic function by mean of the record of myocardial velocities in the longitudinal axis. With the purpose to evaluate diastolic function by pulsed Doppler tissue imaging in patients with Chagas disease, we studied with Doppler echocardiography 51 patients (age average 48 +/- 12 years) and 24 normal subjects (age average 47 +/- 15 years) as a control group.
