Early Detection of Left Ventricular Contractility Abnormalities by Two‐Dimensional Speckle Tracking Strain in Chagas' Disease

In a subgroup of asymptomatic patients with Chagas' disease without evident cardiac involvement, 2D strain was reduced compared with healthy individuals, suggesting incipient LV dysfunction in these patients. 2D ST strain has the potential for detecting early myocardial impairment in the setting of Chagas' disease.
