Abstract: 目的应用三维斑点追踪技术(3D-STI)评价高血压患者左室心肌收缩功能,早期发现高血压患者左室功能变化,为临床干预提供依据。方法原发性高血压患者134例,左心室充盈正常者62例为A组,左心室松弛性减低者72例为B组,正常对照组为年龄及性别相匹配健康志愿者50名。应用3D-STI测量收缩期整体纵向、径向、环向应变(GLS、GRS、GCS)及左室射血分数(LVEF),比较各组间参数差异。结果 3组间LVEF两两比较差异均无统计学意义(P>0.05)。与正常对照组比较,A组GLS减低(P<0.05),GCS、GRS无明显变化(P>0.05),B组GLS、GCS、GRS均减低(P<0.05);与A组比较,B组GLS、GCS、GRS均减低(P<0.05)。结论 3D-STI技术测量左室收缩期整体峰值应变,可较早发现构型正常高血压患者左心室收缩功能的变化,以纵向应变更敏感,可为临床早期干预提供依据。
