不稳定型心绞痛患者冠脉内超声特点与TIMI危险评分的预测价值

The IVUS features of coronary atherosclerosis plaque in unstable angina patients and prediction value of TIMI risk score on it

目的通过不稳定型心绞痛患者冠脉血管内超声测定,探讨TIMI危险评分对冠脉斑块程度预测价值。方法对78例UAP患者进行IVUS检查,而后进行TIMI危险评分;以评分差异分组,分析各组间斑块性质、外弹力膜面积(EA)、管腔横截面积(LA)、斑块面积(PA)、斑块负荷(PA/EA)、偏心指数(EI)的相关性。结果 LA、PA与EI比较中高分与低分组间存在显著差异;而PA/EA的比较中各组间差异均有统计学意义。结论 TIMI高评分组与斑块性质、EA、PA、PA/EA、EI密切相关,且以PA/EA最具临床意义。

Objective To explore the prediction value of TIMI risk score on the degree of coronary artery stenosis in patients with UAP according to IVUS.Methods 78 patients with UAP underwent IVUS in study,and then were evaluated with TIMI risk score.They were divided into three different groups according to TIMI risk score.Three groups were evaluated with the relationship of differrent TIMI risk scores and charater of atherosclerotic plaque,LA,PA,PA/EA and EI.Results The LA,PA and EI were significantly differrent in low score group and high score group,and the PA/EA had statistically significant difference in the three groups.Conclusions High score group of TIMI risk score is closely related to charater of atherosclerotic plaque,EA、PA、PA/EA、EI of coronary artery,and plaque burden has the most important value in predicting the disease of pathological coronary artery.
