【摘要】 探讨心肌梗死（ＭＩ）患者左室舒张功能的评价方法及临床应用。方法：采用脉冲多普勒超声心动 图技术检测５０例正常人和５０例ＭＩ患者的左房收缩时间间期（ＬＡＳＴＩ）。包括左房射血前期（ＡＰＥＰ）、校正心房射血 前期（ＡＰＥＰＣ）和左房射血期（ＡＥＴ）；肺静脉Ｓ峰、Ｄ峰、Ａ峰；二尖瓣血流Ｅ峰、Ａ峰及Ｅ／Ａ比值。ＭＩ组给予抗舒张 障碍治疗３周后再测量各项指标。结果：ＭＩ组的ＡＰＥＰ、ＡＰＥＰＣ缩短，ＡＥＴ延长；肺静脉Ｓ峰、Ａ峰增大，Ｄ峰减小； 二尖瓣Ｅ峰减小，Ａ峰增大（Ｐ＜０．０１）。ＭＩ组治疗３周后各项指标明显改善（Ｐ＜０．０１）。结论：综合多指标分析能 提高左室舒张功能评价的准确性。更多还原

【Abstract】 Aim:To study evaluation and significance of diastolic function of left ventricle in patients with myocardial infarc- tion(MI),Methods pulsed dopler cechocardiography were used to detect the APEP APEPC and AET of left atrial systolic time intervals,the P,S,and A peak velocities of blood flw of pulmonary veins and E and A peak velocties of blood flow of mitral valve Three weeks after ,antidiastolic failure was treated all of indexes were remeasure in MI patients Results :In MI patients, APEP and APEPC shorened AET prolonged S and A peak reduced E,peak reduced and A peak of mitral valve reised Conclusion:Using the above indeses comprehensively the accuracy of evaluation of left ventricular diastolic function can be improved更多还原
