Objective The purpose of the investigation was to study valvular regurgitation, morphological changes and left ventricular function in patients with left ventricular enlargement.

目的：研究左心扩大性疾病瓣膜返流情况、心腔形态学改变以及心功能的变化。

Summed stress scores and left ventricular enlargement provided incremental prognostic information, the researchers note, but including left ventricular ejection fraction did not improve the model.

研究人员注意到：负荷总分和左心室增大程度可以提供更加准确的预后信息，但是射血分数对本模型没有贡献。
