Abstract:

目的探讨围产期心肌病患者在合并不同左心室射血分数情况下的临床特点。方法回顾性分析我院2007年5月至2010年11月期间经妇产科诊断为围产期心肌病合并正常射血分数(EF%≥55%)的患者(n=16)的病例资料,同时选择同期诊断为围产期心肌病合并异常射血分数的患者(EF%<45%)为对照组(n=16)。比较两组患者心功能生化指标、超声心动图指标和预后情况,进行分析总结。结果相比围产期心肌病合并异常射血分数的患者,围产期心肌病合并正常射血分数的患者表现出较低的B型利钠肽水平和较高的左心室收缩和舒张能力,差异具有统计学意义(P<0.05)。同时,其分娩期失代偿心力衰竭发生率及E′二尖瓣环收缩期速度有所下降,差异具有统计学意义(P<0.05)。在随访结果分析中,该类患者的HYHA心功能分级下降(P<0.05),而心衰复发率没有明显差异。结论在超声心动图没有检测到左心室收缩功能障碍的情况下,围产期心肌病合并正常左心室射血分数的患者能出现心功能衰竭,围产期心肌病合并正常射血分数可能是围产期心肌病中的一种亚型。
