Invasive and noninvasive methods used to evaluate ventricular function in Chagas's disease are reviewed. The traditional indices of overall ventricular performance reflect the interaction of preload, contractility, afterload and heart rate. Therefore, they are unable to distinguish changes in contractility from modifications of loading conditions. The role of ventricular function as a predictor of mortality in chronic Chagas' heart disease is discussed. Ventricular function abnormalities in patients with indeterminate and digestive forms of Chagas' disease are especially emphasized. Finally, the evidence of early impairment of diastolic performance in digestive forms of Chagas' disease are especially emphasized. Finally, the evidence of early impairment of diastolic performance in patients with Chagas' disease is presented.
本文综述了用于评估恰加斯病心室功能的有创和无创方法。整体心室功能的传统指标反映了前负荷、收缩力、后负荷和心率之间的相互作用。因此，它们无法区分收缩力的变化与负荷条件的改变。文中讨论了心室功能作为慢性恰加斯心脏病死亡率预测指标的作用。特别强调了恰加斯病不确定型和消化型患者的心室功能异常。最后，文中还特别强调了恰加斯病消化型患者舒张功能早期受损的证据。最后，展示了恰加斯病患者舒张功能早期受损的证据。
