摘要
目的探究64排CT冠状动脉成像下不同性质心绞痛患者斑块特征差异性。方法回顾性选取80例2019年4月至2021年4月于庐山康复疗养中心(九江171医院)确诊为冠心病患者的临床资料,依据患者临床诊断结果将其分为稳定型心绞痛(SAP)组(n=34)及不稳定型心绞痛(UAP)组(n=46)。所有患者均行64排螺旋CT冠状动脉成像检查,比较两组冠状动脉不同位置的斑块数目检出情况[左前降支(LAD)、左冠状动脉主干(LM)、左回旋支(LCX)、右冠状动脉(RCA)],以及两组斑块性质及狭窄情况。结果两组的冠状动脉不同位置斑块数目比较,差异无统计学意义(P>0.05)。UAP组软斑块及混合斑块检出率均高于SAP组,硬斑块检出率低于SAP组,差异有统计学意义(P<0.05)。UAP组轻度狭窄及中度狭窄检出率均高于SAP组,重度狭窄检出率低于SAP组,差异有统计学意义(P<0.05)。结论64排CT冠状动脉成像下可清晰显示不同性质斑块特征,明确不同位置处斑块性质,并可对血管狭窄情况行有效分析,可为临床病情诊疗提供参考。
Objective To explore the differences of plaque characteristics in patients with different types of angina pectoris under 64-slice CT coronary angiography.Methods The clinical data of 80 patients with coronary heart disease diagnosed in Lushan Rehabilitation Center(Jiujiang 171 Hospital)from April 2019 to April 2021 were retrospectively selected,and they were divided into the stable angina pectoris(SAP)group(n=34)and unstable angina pectoris(UAP)group(n=46).All patients underwent 64-slice spiral CT coronary angiography.The number of plaques detected in different positions of the coronary artery(left anterior descending artery(LAD),left main coronary artery(LM),left circumflex artery(LCX),right coronary artery(RCA)],as well as the nature of plaque and stenosis of the two groups were compared.Results There was no significant difference in the number of plaques in different positions of coronary artery between the two groups(P>0.05).The detection rate of soft plaque and mixed plaque in UAP group was higher than that in SAP group,and the detection rate of hard plaque was lower than that in SAP group,the differences were statistically significant(P<0.05).The detection rates of mild stenosis and moderate stenosis in the UAP group were higher than those in the SAP group,and the detection rate of severe stenosis was lower than that in the SAP group,with statistically significant differences(P<0.05).Conclusion 64-slice CT coronary angiography can clearly display the characteristics of plaques of different properties,clarify the properties of plaques at different locations,and effectively analyze the stenosis of blood vessels,which can provide a reference for clinical diagnosis and treatment.
