摘要: 目的探讨视频密度阶差(VDS)评价冠脉造影时心肌微灌注的可行性及应用价值。方法计算58例冠脉造影者的VDS和校正的TIMI帧计数(CTFC)。结果58例冠脉造影正常者其VDS为(22.5±5.8),根据该数据计算心肌正常灌注者VDS的95%可信区间为(20.2,24.7);其CTFC为(21.1±4.5);VDS与CTFC之间存在负相关。结论VDS定量评价心肌微灌注具有可行性,当VDS<20时,存在心肌微灌注障碍的可能性较大。

Abstract: Objective To evaluate the feasibility and the value of video density scale (VDS) for assessing myocardial microperfusion.MethodsVDS and corrected TIMI frame counted (CTFC) were calculated and compared in 58 cases undergoing coronary catheter angiography.ResultsVDS of 58 cases was (22.5±5.8)and 95% confidence interval of normal myocardial microperfusion is(20.2,24.7).The CTFC was (21.1±4.5).It showed negative correlation between VDS and CTFC.ConclusionVDS is feasible to assess myocardial microperfusion quantificationally.The possibility of myocardial microperfusion dysfunction would be increased when VDS is lower than 20.
