摘　　要：目的观察心脏X综合征(CSX)患者的1.5T MR高分辨心肌灌注成像的影像学特征,分析CSX引起临床症状的原因。方法连续纳入2021年6月至2022年8月在杭州医学院附属义乌医院诊断为CSX的患者60例为CSX组和无症状心肌缺血的患者60例为对照组。入选者均接受1.5T MR高分辨心肌灌注成像(MRHMPI),进行房室腔内径和室壁运动分析、T2压脂扫描、首过灌注和增强延迟扫描。比较两组患者的一般资料及心肌灌注成像结果。结果CSX患者女性占比明显高于无症状心肌缺血患者,差异有统计学意义(P<0.05)。1.5T MR高分辨心肌灌注成像结果显示,两组间房室腔内径、室壁运动、T2压脂扫描、首过灌注、延迟扫描异常占比比较,差异无统计学意义(P>0.05)。结论CSX患者的心肌灌注成像改变与无症状心肌缺血的患者类似,都不存在心肌组织水平的灌注异常,说明CSX的症状可能与心肌灌注水平无关。Objective To observe the imaging characteristics of 1.5T MR high-resolution myocardial perfusion imaging in patients with cardiac syndrome X(CSX)and analyze the causes of clinical symptoms caused by CSX.Methods A total of 60 patients diagnosed as CSX(the CSX group)in Yiwu Hospital Affiliated to Hangzhou Medical College from June 2021 to August 2022 and another 60 patients with asymptomatic myocardial ischemia(the control group)during the same period were continuously included.All the selected patients underwent 1.5T MR high-resolution myocardial perfusion imaging(MRHMPI),with the analysis of atrioventricular cavity diameter and wall motion,T2 liposcanning,first-pass perfusion and enhanced delayed scanning performed.The general data and myocardial perfusion imaging results of the two groups of patients were compared.Results The proportion of women patients with CSX was significantly higher than that in the asymptomatic myocardial ischemia patients,with statistically significant difference(P<0.05).The results of 1.5T MR high-resolution myocardial perfusion imaging showed that there were no s tatistically significant differences between the two groups in the percentage of abnormal atrioventricular cavity diameter and wall motion,T 2 liposcanning,first-pass perfusion and delayed scanning(P>0.05).Conclusion The myocardial perfusion imaging changes of patients with CSX are similar to those of patients with asymptomatic myocardial ischemia,with no abnormal perfusion at the myocardial tissue level,indicating that the symptoms of CSX may not be related to the m yocardial perfusion level.
