Abstract:
Objective To explore the relationship between clinical ischemic events and carotid calcification detected by 64 slices CT angiography. Methods We retrospectively analyzed the carotid calcified plaques in 116 patients underwent the 64 slices CT angiography. The relatinnship between the carotid calcification and the clinical ischemic events was analyzed. Results A total of 377 plaques were detected and the incidence of carotid plaque calcification was 63.40%. Incidence of plaque calcification was significantly lower in patients with ages<50 years than that in patients with ages 51-59 years, 60-69 years and higher than 70 years (P=0.003, P=0.002, P=0.000, respectively). The incidence of plaque calcification in the common carotid artery was significantly lower than the carotid bifurcation (P=0.000) and the internal carotid artery (P=0.000). The incidences of calcification in the mild, moderate and severe degree of stenosis and occlusion were 46.54%, 33.33%, 26.67% and 0% respectively. The distribution of intraplaque calcium was similar between patients with ischemic event and non-isehemic event group. However, the incidence of calcification was significantly lower patients with ischemic event than that in patients without ischemie event (30.34% vs. 43.10%, P=0.013). Calcified plaque was negatively associated with ischemie event (β=-0.688, P=0.006). Conclusion 64 slices CT angiography can analyze the characterization of carotid plaque calcium.
