摘要 目的探讨实时三维超声心动图(RT-3DE)在急性肺栓塞(APE)患者右心室功能中的应用价值。方法 110例APE患者进行危险分层,分为APE高危组(36例)、APE中危组(39例)、APE低危组(35例),同期35例健康体检者作为对照组。应用RT-3DE测算比较右心室横径(RV)、肺动脉收缩压(SPAP)、右心室舒张末期容积(RVEDV)、每搏量(RVSV)、右心室射血分数(RVEF)、右心室峰值排空率(PER)、右心室Tei指数。结果与对照组和APE低危组、中危组比较,APE高危组RV、SPAP、RVEDV和Tei显著升高(P<0.05),RVEF和PER显著降低(P<0.05)。校正心率后,Tei[OR=5.596,95%CI=(1.599,19.579),P=0.007<0.05]和SPAP[OR=1.870,95%CI=(1.171,2.988),P=0.009<0.05]仍能进入回归方程,提示两者是APE危险分层的独立危险因素。结论 Tei指数和SPAP是评价APE右心室功能的较好指标,可以用于危险分层。
