【摘要】：目的:探讨双源CT血管成像(DSCTA)评价非ST段抬高型急性冠脉综合征(NSTE-ACS)的价值。方法:搜集临床疑似NSTE-ASC且经DSCTA判断为左冠状动脉前降支管腔临界狭窄(狭窄程度为50%~70%)的患者57例,1周内行冠脉造影(CAG)证实狭窄程度,并行导管法测量血流储备分数(FFR),以FFR 0.80为临界值将57例患者分为A组(FFR0.80)和B组(FFR≥0.80),测量左室前壁、侧壁心肌、左心室腔CT值及舒张末期、收缩末期节段室壁厚度,比较两组间前壁与侧壁相对CT值、舒张末期心肌厚度及室壁增厚率。结果:A、B两组前壁与侧壁心肌相对CT值及舒张末期心肌厚度差异均有统计学意义(P0.05),A组前壁与侧壁室壁增厚率差异有统计学意义(P0.05),B组前壁与侧壁室壁增厚率差异无统计学意义(P0.05);前壁心肌相对CT值及室壁增厚率A、B两组间差异有统计学意义(P0.05),而舒张末期心肌厚度A、B两组间差异无统计学意义(P0.05)。结论:DSCTA评价左冠状动脉前降支管腔临界狭窄联合节段心肌CT值、舒张末期心肌厚度及室壁增厚率分析,可为NSTE-ACS的诊断及治疗提供依据。
[Abstract]:Objective: to evaluate the value of dual-source CT angiography (DSCTA) in the evaluation of non-ST segment elevation acute coronary syndrome (NSTE-ACS). Methods: 57 patients with suspected NSTE-ASC who were diagnosed by DSCTA as critical stenosis of left anterior descending coronary artery (50%) were examined by (CAG) within 1 week. 57 patients were divided into two groups: group A (FFR0.80) and group B (FFR 鈮，
