摘　　要：目的探讨256层螺旋CT技术对糖尿病合并心肌损伤患者的诊断的临床价值。方法选择2014年1月~2016年6月我院收治的未经治疗或血糖控制不佳的非冠心病Ⅱ型糖尿病患者(无先天性心脏病、风湿性心脏病、高血压及其他影响心功能疾病)100例作为观察组,另选择我院同期非冠心病非糖尿病健康人员100例作为对照组,两组均进行心脏256层螺旋CT血管造影(CTA)检查,计算出舒张末期容积(EDV)、收缩末期容积(ESV)、每搏输出量(SV)、射血份数(EF)、心肌质量(MM)。结果观察组患者经心脏冠状动脉CTA扫描EDV、ESV、MM等指标明显高于对照组,而EF低于对照组,且差异均有统计学意义(P<0.05);两组患者SV比较差异无统计学意义(P>0.05);观察组患者经心脏冠状动脉CTA扫描舒张末期左心室后壁厚度和室间隔厚度明显高于对照组,而收缩期左心室后壁增厚率和室间隔增厚率均低于对照组,且两组比较差异均有统计学意义(P<0.05);两组收缩末期左心室后壁厚度和室间隔厚度比较差异无统计学意义(P>0.05)。结论 256层螺旋CT血管造影三维后处理技术能准确分辨糖尿病患者心功能与正常人的早期差异,在诊断糖尿病合并心肌损伤患者具有很好的优势。Objective To investigate the clinical value of 256 slice CT technology for merger of diabetes and myocardial injury. Methods 100 cases without treatment or poor glycemic control in type lldiabetie patients without coronary heart disease（no congenital heart disease, rheumatic heart disease,high blood pressure and other effects of heart function disease） cured in our hospital from January 2014 to June 2016 were selected as the observation group,and the otherl00 eases of non-diabetic healthy people and non-coronary heart disease in our hospital over the same period were selected as the control group.All the patients in both groups were given 256-slice cardiac CT angiography（CTA）examination to calculate the end-diastolic volume （EDV）,end-systolic volume（ESV）,stroke volume（SV）,ejection fraction（EF）,myocardial mass（MM）. Results The coronary CTA scan EDV,ESV,MM and other indicators of patients in observation group were significantly higher than those of control group,while the EF was lower than the control group,and the differences were statistically significant（P 〈0.05）.There was no significant difference on differences of SV between the two groups（P 〉 0.05）.The coronary CTA scan after the end-diastolic wall thickness and left ventricular septal thickness of patients in observation group were significantly higher,while systolic left ventricular posterior wall thickening and septal thickening were lower than the control group,and the differences were statistically significant（P 〈 0.05）.Wall thickness and interventricular septum thickness difference were not statistically signifieant（P 〉 0.05）. Conclusion 256 slice spiral CT angiography in the diagnosis of myocardial injury in patients with diabetes mellitus has a good advantage and clinical application value.
