目的分析冠心病合并糖尿病患者冠状动脉血管内超声影像特点。方法将冠心病患者141例依据是否合并糖尿病分为观察组(合并糖尿病)51例和对照组(无糖尿病)90例,所有患者均于冠脉造影检查后行血管内超声检查,利用血管内超声观察2组病变血管特征。结果观察组三支病变明显多于对照组,单支病变少于对照组,差异有统计学意义(P<0.05);2组双支病变发生率比较差异无统计学意义(P>0.05)。2组斑块类型比较差异无统计学意义(P>0.05)。观察组合并钙化比例高于对照组,病变血管最小管腔面积(MLA)明显小于对照组,斑块负荷(PB)大于对照组,差异均有统计学意义(P<0.05)。结论冠心病合并糖尿病患者病变血管MLA更小,钙化更常见,斑块负荷重,管腔狭窄更弥漫、更严重。
Objective To analyze coronary angiography features of coronary heart disease complicated with diabetes mellitus. Methods 141 patients with coronary heart disease were divided into observation group (with diabetes mellitus) and control group (n = 90) according to whether they had diabetes or not. All patients underwent coronary angiography after coronary angiography and intravascular ultrasound The vascular characteristics of the two groups were observed. Results The three lesions in the observation group were significantly more than those in the control group. The single vessel lesion was less than the control group (P <0.05). There was no significant difference in the incidence of the double vessel lesion between the two groups (P> 0.05). There was no significant difference in the type of plaque between the two groups (P> 0.05). The ratio of observation group and calcification was higher than that of the control group. The lesion lumen minimal lumen area (MLA) was significantly smaller than that of the control group and the plaque burden (PB) was larger than that of the control group. The difference was statistically significant (P <0.05). Conclusions Lesions in patients with coronary heart disease and diabetes mellitus have smaller MLA, calcifications are more common, plaque burden is heavier and stenosis is more diffuse and more serious.
