摘要 目的观察急性肺栓塞(APE)患者右室壁心肌应变的特点,探讨二维斑点追踪技术(2D-STI)在评价APE右室收缩功能中的价值。方法将CT肺动脉造影(CTPA)确诊的APE患者78例分为高危组(21例)、中危组(29例)与低危组(28例),以健康体检正常者30例为对照组。应用2D-STI技术分别测量右室侧壁及室间隔的基底段、中间段、心尖段心肌纵向收缩峰值应变(PSS)。结果中、高危组右室侧壁及室间隔各节段心肌PSS均低于对照组(P<0.05);中、高危组间各节段心肌PSS差异均无统计学意义(P>0.05)。低危组右室侧壁中间段及室间隔基底段、中间段心肌PSS低于对照组(P<0.05)。高危组各节段心肌PSS均低于低危组(P<0.05);中危组右室侧壁基底段、心尖段及室间隔心尖段低于低危组(P<0.05),其他节段与低危组比较差异无统计学意义(P>0.05)。结论 2D-STI技术可准确、敏感反应APE患者右室收缩功能变化,为临床评价右心功能提供较好的检测方法。
