| 目的：探讨缺血性二尖瓣反流与二尖瓣环位移的关系。方法：2011 年1 月至2012 年12月前壁或下壁心肌梗死的患者107
人和40 名健康志愿者，分为反流组和无反流组。应用超声心动图组织运动二尖瓣环位移技术检测他们的左室射血分数、二尖瓣环最大位移、二尖瓣环中点位移及其占左室长径百分比。结果：反流组与无反流组二尖瓣环位移测值均低于对照组，差别有统计学意义（P＜0.05）。前壁心梗反流组和下壁心梗反流组二尖瓣环最大位移较相应的无反流组减低，差别有统计学意义（P＜0.05）；二尖瓣环前壁-下壁中点位移及其所占左室长径百分比减少，与无反流组相比差别有统计学意义（P＜0.01）。结论：应用二尖瓣环运动自动追踪技术能够更准确地测量二尖瓣环运动，可以用来评价缺血性二尖瓣反流，为定量分析左心功能提供了新的检查方法。 |

| Objective:To investigate the correlation between ischemic mitral regurgitation（IMR）and mitral annular displacement.Methods:A total of 107 patients with anterior myocardial infarction(AMI) or inferior myocardial infarction (IMI), and 40 volunteers from
January 2011 to December 2012 were divided into ischemic mitral regurgitation (IMR) group and no-ischemic mitral regurgitation
(NIMR) group to detect their degree of left ventricular ejection fraction, mitral annular displacement (MAD), maximum displacement of
the midpoint (MAD mid) and the percentage of MAD Mid in length diameter of ventriculus sinister (MAD mid%) by echocardiography
and tracking of mitral annular displacement (TMAD).Results:TMAD measurements significantly reduced in patients of NIMR group or
IMR group compared with that of the control group (P＜0.05). MAD measurements significantly reduced in patients of IMR-AMI group
and IMR- IMI group compared with that of the NIMR group (P＜0.05). MAD mid and MAD mid%of anterior-inferior wall significantly
reduced in patients of IMR-AMI group and IMR-IMI group compared with NIMR group.Conclusion:It can more accurately measure
the mitral valve annulus movement parameters by application of TAMD, which can be used to evaluate the ischemic mitral regurgitation.
It provides a new inspection method for the quantitative analysis of left heart function. |
