应用64排螺旋CT检测合并糖尿病的心绞痛患者冠状动脉粥样硬化斑块特点

目的利用MSCT血管造影探讨合并糖尿病的心绞痛患者冠状动脉粥样硬化斑块特点。资料与方法以接受64排螺旋CT冠状动脉造影检查的心绞痛患者60例为研究对象,其中合并糖尿病者30例,无糖尿病者30例。观察并比较两组患者的冠状动脉粥样硬化斑块的分布特点与类型特点。结果与非糖尿病组相比,糖尿病组具有更多的混合斑块。经年龄和性别调整后,糖尿病是混合斑块的独立危险因素。结论 MSCT冠状动脉造影能够准确反映动脉粥样硬化斑块在糖尿病和非糖尿病患者之间的差异,合并糖尿病的心绞痛患者由于混合斑块的增加而处于易发心血管事件的高危状态。

Characteristics of Atheromatous Plaque in Coronary Artery in Angina Patients with Diabetes Using 64 Slice Spiral CT Angiography

Objective To investigate the characteristics of atheromatous plaque in coronary artery in angina patients with diabetes using 64 slice spiral CT angiography.Materials and Methods 60 angina patients received MSCT angiography examinations,among them,30 were diabetes and 30 were non diabetes patients.The characteristics of distribution and type of atherosclerotic plaque were observed and compared between two groups.Results Patients with diabetes had a higher prevalence of mixed plaques compared with non diabetic patients.After adjustment for age and sex,diabetics was an independent factor for mixed plaques.Conclusion Differences in coronary plaque composition between diabetic and non diabetic patients can be detected accurately by MSCT angiography.In patients with diabetes,increased mixed plaque types contribute to a high risk for cardiovascular events.
