摘要
目的探讨冠脉慢性完全闭塞性病变(CTO)患者采用多层螺旋CT(MSCT)评估冠状动脉主干及左心室功能的价值。方法选取2021年3月至2022年3月在本院收治的CTO患者共计80例,所有患者均实施超声心动图检查及MSCT检查,分析MSCT对患者冠状动脉主干情况及左心室功能的评估价值。结果80例患者中共87支冠脉主干发生闭塞;闭塞病变性质中25支为钙化斑块、20支软斑块,42支为混合斑块;发现20支为闭塞主干近端分支血管扩张,闭塞段成角弯曲18支,25支为合并其他冠状动脉主干管腔严重狭窄,11支为支动脉主干窦上起源,13支为窦房结动脉开口硬化斑;在左心室射血分数(LVEF)、左心室收缩末期容积(LV-ESV)、左心室舒张末期容积(LV-EDV)及左心房内径(LAD)上,两组比较差异无统计学意义(P>0.05)。结论MSCT能够对CTO患者冠状动脉主干情况进行充分显示,有效判断患者左心室功能情况,有利于为患者治疗提供依据,促进闭塞血管再通。
Objective To explore the value of multi-slice spiral CT(MSCT)in assessing the function of the main coronary artery and left ventricular function in patients with chronic total occlusive disease(CTO).Methods A total of 80 CTO patients from March 2021 to March 2022 who were admitted in our hospital were selected,and all patients underwent echocardiography and MSCT.The evaluation value of MSCT on the condition of the main coronary artery and left ventricular function of patients were analyzed.Results A total of 87 coronary arteries were occluded in 80 patients.Among the occlusive lesions,25 were calcified plaques,20 were soft plaques,and 42 were mixed plaques;It was found that 20 branches of the proximal end of the occluded main artery were dilated,18 branches of the occluded segment were angled and curved,25 branches were complicated with severe stenosis of other main coronary arteries,11 branches were from the superior sinus of the main branch artery,and 13 branches were sclerotic plaques at the opening of the Sinoatrial node artery;There was no significant difference in left ventricular Ejection fraction(LVEF),left ventricular end systolic volume(LV-ESV),left ventricular end diastolic volume(LV-EDV)and left atrial diameter(LAD)between the two groups(P>0.05).Conclusion MSCT can fully display the main coronary artery in CTO patients,effectively judge the left ventricular function of patients,and help provide a basis for patients'treatment and promote the recanalization of occluded vessels.
