[Prevalence of left ventricular aneurysms among chronic Chagas disease patients from two areas in the State of Piauí, Brazil].
A cross-sectional study involving a cohort of 261 chronic Chagas disease patients (156 from the municipality of João Costa and 105 from São João do Piauí; 146 women and 115 men with mean age of 57.9 +/- 14.2 years) was carried out to evaluate the prevalence of left ventricle aneurysms. The cardiological evaluation was performed by means of clinical examination, resting electrocardiograms and one and two-dimensional echocardiograms. A total of 23 cases of left ventricle aneurysms (8.8%) were diagnosed: 17 (6.5%) in the apical segment, four (1.5%) in the posterior wall, one (0.4%) in the inferior wall and one (0.4%) in the interventricular septum. Five patients (1.9%) from São João do Piauí presented thrombi associated with apical aneurysms. The prevalence of left ventricle aneurysms was greater among the patients from São João do Piauí (13.3%) and among men (13.9%), with no significant difference in relation to age group. These results show that there was low prevalence of left ventricle aneurysms among patients from João Costa and high concentration of thrombi among patients from São João do Piauí.
