2.3 肥胖对高血压组左房功能影响 关,与 LASct 无明显相关,年龄与 LASr、LAScd 呈独
高血压组中,随 BMI 增加,左房储备功能、导管 立负相关,SBP 与左房各功能指标均无明显相关性
期纵向应变及机械功能指数均呈下降趋势,LASct (表3)。
无明显改变但LAEFa呈下降趋势;正常体重高血压 3 讨 论

随BMI 增加,肥胖高血压组与正常体重高血压组间 左房曾经是“被遗忘的腔室”,然而,近年诸多
LASr、LAEFt、LAScd、LAEFp 及 LAEFa 差异均有统 研究发现,左房构型及功能改变是冠心病、高血压

多元线性回归表明:在高血压患者中,BMI 与 房功能对不良心血管事件的诊疗及预后具有重要
LASr、LAEFt、LAScd、LAEFp、LAEFa 均呈独立负相 意义 [9-10] 。
