Objective To explore the plaque properties of patients with angina pectoris evaluated by coronary computerized tomography angiography (CTA) and their correlation with cardiovascular events. Methods The related data of 216 patients with angina pectoris in our hospital were analyzed retrospectively. According to the clinical data, they were divided into stable angina pectoris group (SAP group, 78 cases) and unstable angina pectoris group (UAP group, 138 cases). The differences in plaque properties were compared between the two groups, and the correlation between cardiovascular events and plaque properties was analyzed. Results The plaques were mainly calcified plaques in SAP group, and were soft plaques in UAP group. There was no statistically significant difference in the rate of mixed plaques between the two groups (P>0.05). The soft plaques rate in SAP group was significantly lower than that in UAP group (P<0.05) while the calcified plaques rate was higher than that in UAP group (P<0.05). There were 8 cases (10.26%) of cardiovascular events in SAP group and were 41 cases (29.71%) of cardiovascular events in UAP group. There was no significant difference in the mixed plaques rate between patients with cardiovascular events and patients without cardiovascular events within the two groups (P>0.05). The soft plaques rate in patients with cardiovascular events was significantly higher than that in patients without cardiovascular events (P<0.05), but the calcified plaques rate was lower than that in patients without cardiovascular events (P<0.05). Conclusion Soft plaque is closely related to cardiovascular events in patients with angina pectoris. Coronary CTA can effectively evaluate the plaque properties and play a role in predicting the prognosis of patients.
