摘要 目的观察窦性心律慢性心力衰竭(心衰)患者左心室几何形态、左心室收缩功能及二尖瓣返流的变化,探讨左心室几何形态对左心室收缩功能的影响。方法选择26例慢性心衰患者(病例组),NYHA分级Ⅱ~Ⅲ级,均符合Framingham心衰诊断标准。对照组16例,无器质性心脏病,无心衰症状及体征,超声心动图示左心室射血分数正常。进行超声心动图检查获得相关参数。结果2组间超声心动图测量的左心室几何构型参数Cole’s指数及面积长度指数差异有统计学意义(P均<0.05),左心室射血分数(LVEF)明显不同(P<0.01)。结论慢性心衰患者的心脏几何构型、左心室射血分数存在着明显异常,有显著的二尖瓣反流,说明左心室收缩功能不良与左心室几何形态有关。
