摘要 目的探讨超声二维应变技术(2DSI)评价非ST段抬高型急性冠状动脉综合征(NSTE-ACS)患者危险分层的作用。方法选择2012年1月至2014年6月在我院诊断为NSTE-ACS患者90例,依据全球急性冠状动脉事件注册研究(GRACE)危险积分作危险分层(高、中、低危组,n=30)。应用2DSI测量各组患者左心室各心肌节段收缩期最大纵向应变(LS)、径向应变(RS)、圆周应变(CS)、心尖部扭转角度(RA),对最大应变值的均值进行组间比较,并与GRACE危险积分进行相关性分析。结果 NSTE-ACS患者的左心室收缩期LS、RS、CS峰值的均值均与GRACE危险积分呈负相关(r值分别为-0.61、-0.74、-0.58,P均<0.05),心尖部RA与GRACE危险积分无明显相关性(P>0.05)。高危组患者左心室收缩期LS、RS、CS均显著低于中、低危组(P<0.01)。结论 2DSI能无创定量分析NSTE-ACS患者的左心室心肌应变,部分应变峰值提示NSTE-ACS风险程度,2DSI对NSTE-ACS危险分层起重要的评价作用。
