摘要
目的研究64层螺旋CT冠状动脉成像显示的急性冠脉综合征(ACS)患者和稳定型心绞痛(SAP)患者的冠状动脉内的斑块情况。方法选取2006年在我院接受64层螺旋CT冠状动脉成像和选择性冠状动脉造影检查(这两项检查的间隔时间不超过1个月)的ACS患者42例和SAP患者44例。将两组患者的CT检查结果与选择性冠状动脉造影检查结果进行比较分析。结果ACS组和SAP组的软斑块和钙化斑块的构成比间差异有统计学意义(χ2=6.860,P=0.009);两组患者软斑块和钙化斑块在不同冠状动脉分支内的分布差异均无统计学意义(χ2ACS=0.174,χ2SAP=0.129,P>0.05);两组患者软斑块和钙化斑块在不同狭窄程度的冠状动脉节段中的分布不同(χ2ACS=0.398,χ2SAP=0.907,P<0.01);ACS组和SAP组患者在不同冠状动脉分支内,软斑块在不同狭窄程度的血管节段内的分布差异无统计学意义(χA2CS=3.917,χ2SAP=0.416,P>0.05);SAP组和ACS组患者在不同的冠状动脉分支内,钙化斑块在不同狭窄程度的血管节段内的分布差异有统计学意义(χA2CS=5.247,χ2SAP=11.054,P<0.01)。结论64层螺旋CT冠状动脉成像能鉴别斑块性质,有助于早期识别冠心病高危患者,为治疗决策提供评价依据。
Objective To study the plaques inside coronary arteries showed by 64 - slice spiral CT coronary angiography in patients with acute coronary syndrome （ACS） or stable angina pectoris （SAP）. Methods Forty -two ACS patients and 44 SAP receiving 64 - slice spiral CT coronary angiography and selective coronary angiography （ the interval between 2 examinations were less than 1 month） in 2006 were enrolled. The 2 findings were compared. Results There was significant difference in soft and calcified plaque composition percentage between 2 groups （ X2 = 6. 860, P = 0. 009 ）, but there was not in plaque distribution in different coronary artery branches （x^2ACScs =0. 174, x^2SAP =0. 129, P 〉0. 05）. The distributions of soft and calcified plaques varied in different coronary artery segments in different stenosis degrees in 2 groups （ X^2ACS = 0. 398, X^2SAP= 0. 907, P 〈 0. 01 ）. There was not significant difference between 2 groups in soft plaque distribution in vessel segments in different stenosis degrees in different coronary artery branches （ X^2ACS = 3. 917,X^2SAP = 0. 416, P 〉 0. 05 ）, but there was in calcified plaque distribution （X^2ACS = 5. 247 , X^2SAP = 11. 054, P 〈 0. 01 ）. Conclusion 64 - slice spiral CT coronary arteriography can be used to judge the nature of plaque timely to discover high - risk coronary disease patients at early stage, thus to provide information and data for early treatment decision.
