The imaging of angiography of non-ST segment elevation acute coronary syndrome under 64-dector CT

Objective:To explore the imaging of angiography of non-ST segment elevation acute coronary syndrome(NSTEACS) under 64-dector CT.Methods:Coronary artery angiography of twenty normal persons and thirty-five patients with NSTEACS were detected using 64-detector computed tomography,64-MDCT.The data of the lesion site,vessel involved number,plaque nature(calcified plaque,non-calcified plaque or mixed plaque),stenosis(degree and length) and the obstructed vessel were analysed.Results:There was significant statistic difference in the incidence of calcified plaque and plaques involving the coronary artery number(P0.01),but no significant statistic difference in myocardial bridge and plaque site(P0.05),and the narrow rates of coronary artery ranged from 15% to 100% in NSTEACS group.Conclusions:The imaging features of NSTEACS show extensive calcified plaque,multiple vessels involved and the wide stenosis of coronary artery,which can guide.clinical service.
