Abstract:Objective To study the value of 64-slice (computed tomography)CT coronary artery imaging in occult coronary heart disease(CHD).Methods A total of 58 patients with occult CHD who received treatments in our hospital from January 2016 to December 2018 were enrolled.All patients were performed with 64-slice CT coronary artery imaging.The diagnostic results of all patients were compared with the gold standard and the examinations were analyzed in details.Results The results of coronary angiography (CAG)were used as the gold standard.Among them,patients with mild stenosis accounted for 68.97%,and moderate stenosis for 31.03%.After comparison,the incidence of single coronary artery stenosis was 72.41%,and multiple was 27.59%,which was not displayed statistical difference between the 64-slice spiral CT and CAG (P>0.05).After 64-slice spiral CT examinations in all participants,and there were 462 segments of coronary artery segment with a diameter of more than 2 mm.The image quality was observed after the patient′s examination.The image quality satisfied the clinical diagnosis accounted for 85.50%,and the rest was not qualified (14.50%),of which diagonal branch image was 21.43%,followed by the distal segment of left circumflex(20.59%),and the proximal segment of left circumflex (17.14%).The image quality of left main coronary artery can meet the clinical evaluation in a high proportion accounting for 90.91%,followed by the distal segment of left anterior descending branch (90.39%)and proximal segment of left anterior descending branch (89.66%).Conclusion For patients with suspected occult CHD,64-slice CT coronary artery imaging can be used for diagnosis,which benefits for timely diagnosis of coronary artery condition and plaque property,and actively improve patient′s prognosis.It is worthy of application.
