摘　　要：目的:探讨冠状动脉计算机断层血管造影(CTA)在急性冠脉综合征(ACS)诊断中的应用价值。方法:选取2023年3月—2024年2月厦门大学附属第一医院收治的450例临床诊断为ACS的患者作为研究对象,均进行冠状动脉CTA及冠状动脉血管造影(CAG)。以CAG结果为“金标准”,比较分析冠状动脉CTA的诊断价值。结果:冠状动脉CTA与CAG450支血管均检查。其中,CTA检出狭窄血管336支,其中左主干、左回旋支、左前降支及右冠脉的支数分别为75支、80支、97支及84支;CAG检出狭窄血管342支,其中左主干、左回旋支、左前降支及右冠脉的支数分别为78支、83支、93支及88支;两种检查方式检出左主干、左回旋支、左前降支及右冠脉的检出结果比较,差异无统计学意义(P>0.05)。CTA检出无狭窄、轻度狭窄、中度狭窄及重度狭窄的支数分别为114支、190支、76支及70支;CAG检出无狭窄、轻度狭窄、中度狭窄及重度狭窄的支数分别为108支、193支、79支及70支;两种检查方式检测冠状动脉狭窄程度比较,差异无统计学意义(P>0.05)。CTA检出软斑块287个,硬斑块49个,与CAG检出的280个和62个比较,差异无统计学意义(P>0.05)。结论:对ACS患者实施冠状动脉CTA检查是一种有效的诊断手段,其诊断冠状动脉狭窄程度及斑块性质的价值与CAG一致。Objective:To evaluate the diagnostic value of coronary arrery computed tomographic angiography(CTA)in acute coronary syndrome(ACS).Method:A total of 450 patients with clinical diagnosis of ACS admitted to the First Affiliated Hospital of Xiamen University from March 2023 to February 2024 were selected as the study objects.Coronary CTA and coronary angiography(CAG)were performed in all patients.Taking CAG results as the"gold standard",and the diagnostic value of coronary CTA was compared and analyzed.Result:450 vessels of coronary artery CTA and CAG both examined.Among them,336 stenosis vessels were detected in CTA,and the numbers of left main,left circumflex,left anterior descending and right coronary arteries were 75,80,97 and 84,respectively.CAG detected 342 stenosis vessels,and the number of left main,left circumflex,left anterior descending and right coronary arteries were 78,83,93 and 88,respectively.There was no significant difference in the detection results of left main artery,left circumflex branch,left anterior descending branch and right coronary artery between the two methods(P>0.05).There were 114,190,76 and 70 CTAs with no stenosis,mild stenosis,moderate stenosis and severe stenosis,respectively.108,193,79 and 70 branches of CAG were detected without stenosis,mild stenosis,moderate stenosis and severe stenosis,respectively.There was no significant difference in the degree of coronary artery stenosis between the two methods(P>0.05).There were 287 soft plaques and 49 hard plaques detected by CTA,and the differences were not statistically significant compared with 280 and 62 detected by CAG(P>0.05).Conclusion:Coronary CTA is an effective diagnostic method for ACS patients,and its value in diagnosing the degree of coronary artery stenosis and the nature of plaque is consistent with CAG.
