| 目的利用M 型超声测定二尖瓣环运动(MAM) 评价左室舒张功能。方法陈旧性心梗(OMI) 及正常
人各35 例,记录二尖瓣环舒张早期和晚期M 型运动曲线的下降幅度( EM、AM) 和斜率(SM、SA) 及二尖瓣口血流频
谱。结果OMI 组的EM 明显降低(5.61 ±1.32 vs 8.82 ±1.75 , P < 0.001) ,SE 下降(43.12 ±14.10 vs 73.92 ±
21.44 , P < 0.001) ,EM/ AM 低(1.06 ±0.358 vs 1.67 ±0.44 , P < 0.001) ,EM 及EM/ AM 与多普勒血流参数E/ A 具
有相关( r = 0.679 , P < 0.001 , r = 0.638 , P < 0.001) ,以EM < 6.93 为标准判断有无舒张功能不全的敏感性和特异
性分别为97.14 %和91.43 %。结论MAM 方法适用于无创评估OMI 患者的左室舒张功能。 |

| Objective To define the role of mitral annulus motion (MAM) for detecting diastolic function in patients
with old myocardial infarction. Methods Echocardiography were performed in 35 patients with myocardial infarction and
35 normal participants. The amplitude of early diastolic motion ( EM) and later diastolic motion (AM) ,slope E (SE) ,slope
A (SA) of the septal mitral annulus were derived from M-mode analysis , the mitral inflow pattern were also obtained by
pulsed Doppler. Results In the group with OMI , a significant reduction of EM (5. 61 ±1.32 vs 8.82 ±1.75 , P < 0. 001)
and SE (43.12 ±14.10 vs 73.92 ±21.4 , P < 0.001) were detected. EM/ AM decreased (1.06 ±0.36 vs 1.67 ±0.44 ,
P < 0.001) . Using EM < 6.93 mm as a cut points ,sensitivity and specifivity for the detection of diastolic dysfunction were
97.14 % and 91.43 % respectively. There were significant relation between E/ A and EM ( r = 0.679 , P < 0.01) ,SE ( r =
0.604 , P < 0.01) ,EM/ AM ( r = 0.638 , P < 0.01) . Conclusion MAM may be a useful tool for assessing LV diastolic
dysfunction in patients with OMI. |
