[Evaluation of the function and ventricular synchrony in patients with latency stage of Chagas' disease].

Objective: To compare the left ventricular function and the ventricular synchrony in patients with Chagas disease in latency stage respect to a control group.

Methods: We analyze a prospective, comparative, transversal and non randomized study of the left ventricular function (LVF) and the ventricular contraction synchronicity (VCS) in 36 subjects with positive serology for Chagas disease (18 males and 18 females), with mean of 15 +/- 5-years-old. The findings were compared with respect to 23 control volunteers (11 males and 12 females) with mean of 28 +/- 5-years-old.
