目的:探讨超声心动图实时三平面(Real-time Triplane)自动化功能成像(Automated Function Imaging,AFI)技术评价左室构型正常的原发性高血压患者左室纵向收缩功能的临床价值.方法:左室构型正常的原发性高血压患者32例为高血压病组,健康体检者30例为对照组.采用实时三平面AFI技术测量并比较两组左室局部纵向收缩峰值应变(RLS)及整体纵向收缩峰值应变(GLS).结果:高血压病组患者左室侧壁、下壁、室间隔基底段、下壁中间段RLS较对照组减低,差异有统计学意义(P<0.05),其它节段RLS及GLS两组比较差异无统计学意义(P>0.05).结论:实时三平面AFI技术为早期、准确评价左室构型正常的原发性高血压患者左室局部纵向收缩功能提供了新的方法.%Objective: To investigate the clinical application of real-time triplane automated function imaging (AFI) in estimating left ventricular long-axis systolic function in essential hypertensive patients with normal geometry. Methods: Thirty-two essential hypertensive patients with normal geometry were included in the study as hypertention group, and thirty normal persons were included as control group. Reginal long-axis peak systolic strain (RLS) of each left ventricular segment and global long-axis peak systolic strain (GLS) of left ventricular were acquired by real-time triplane AFI. Results: Compared with the control group, RLS of basal lateral, inferior, septal and mid inferior were significantly lower in hypertention group ( P <0. 05) , while the RLS of the other segments and GLS between the two groups were not significantly different ( P >0. 05). Conclusion: Real-time triplane AFI provides us a new method to assess the left ventricular long-axis systolic function in hypertensive patients with normal geometry early and exactly.
