应用冠脉血流显像新技术对正常冠脉血流频谱的分析

Analysis of Coronary Artery Flow in Normal Subjects Using Coronary Artery Flow Imaging

本文利用冠脉血流显像技术分别测量３７例正常人冠脉主干、主要分支及室间隔心肌内舒张期冠脉血流充盈时间（ＤＥＴ）、充盈时间与心动周期的比值（ＤＥＴ／ＲＲ）、加速度（ＡＶ）、减速度（ＤＶ）、速度时间积分（ＶＴＩ）、最大血流速度（Ｖｍａｘ）及平均血流速度（Ｖｍｅａｎ）等项指标，分析了冠脉血流测量的影响因素。该技术为冠状动脉血流动力学研究提供了一项无创性检测方法，具有广阔的应用前景。

Using coronary artery flow imaging,the time of diastolic flow ,time of diastolic flow/cycstol,accleration,deccleration,VTI,Vmax and Vmean in coronary arterys were measured.The infective factors on the measurements of coronary artery flow were analysed.The new coronary artery flow imaging provide a noninvasive quantificational method of hemodynamics of coronary artery flow.
