| 摘 要： | 目的 探讨应变及应变率成像评价尿毒症患者左、右心室心肌局部舒缩功能的价值.方法 34例尿毒症患者根据左心室肥厚与否分为左心室非肥厚组18例,左心室肥厚组16例.正常对照组为30名健康者.测量各组左、右心室壁基底段及中间段的最大应变(ε)、收缩期峰值应变率(SRs)、舒张早期应变率(SRe)和舒张晚期应变率(SRa).结果 左心室:各节段ε、SRs及SRe均为左心室非肥厚组和左心室肥厚组小于正常对照组,大部分节段左心室非肥厚组大于左心室肥厚组;SRa:左心室非肥厚组大于左心室肥厚组,左心室非肥厚组部分节段小于正常对照组,部分节段大于正常对照组,左心室肥厚组大部分节段小于正常对照组.右心室:各节段的ε、SRs及SRe均为左心室非肥厚组和左心室肥厚组小于正常对照组,SRa为正常对照组＜左心室非肥厚组＜左心室肥厚组.结论 应变及应变率能敏感地定量评价尿毒症左、右心室心肌局部舒缩功能. |
