title: Apical left ventricular aneurysms and cardiac parasympathetic innervation in Chagas' heart disease.
abstract: Left ventricular apical aneurysms are present in Chagasic patients who have normal cardiac parasympathetic innervation. Cardiac parasympathetic abnormalities are found, in later stages of the disease, when diffuse myocardial damage and ventricular dilatation are already present. The apical region of the left ventricle is also affected in several acute and chronic non-Chagasic cardiac diseases. Therefore, thinning of the left ventricular apex, with aneurysm formation, may be a non-specific myocardial sequelae, secondary to myocardial damage.
