Abstract:
Objective To explore the characteristics and diagnostic value of coronary computed tomography angiography(CCTA)and dynamic load computed tomography myocardial perfusion imaging(CT-MPI)in patients with obstructive coronary artery disease(CAD)complicated by type 2 diabetes mellitus(T2DM).Methods A total of 187 patients with obstructive CAD were selected and divided into T2DM group(n=70)and non-T2DM group(n=117).All patients underwent CCTA and dynamic load CT-MPI exami-nations.The characteristics of CCTA and dynamic load CT-MPI were observed,and their diagnostic values were analyzed.Results The degree of stenosis,total plaque volume,lipid plaque volume,calcified plaque volume,myocardial perfusion abnormality,and myocardial blood flow(MBF)were independent influencing factors for obstructive CAD complicated by T2DM(P＜0.05).These parameters demonstrated significant diagnostic efficiency on patients with obstructive CAD complicated by T2DM(P＜0.05).Conclusion Obstruc-tive CAD patients complicated by T2DM exhibit characteristics such as high vascular stenosis,severely reduced blood perfusion,and a high prevalence of high-risk plaques.Both CCTA and dynamic load CT-MPI have substantial diagnostic value on this population.
