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 evaluate the predictive value of TIMI risk score on the degree of coronary artery plaque by intracoronary ultrasound in patients with unstable angina pectoris. Methods 78 patients with UAP underwent IVUS examination and then TIMI risk score. According to the difference group, the plaque quality, the area of extra-elastic membrane (EA), lumen cross-sectional area (LA) and plaque area PA), plaque burden (PA / EA) and eccentricity index (EI). Results There was a significant difference between the high and low scores of LA, PA and EI, while there was a significant difference among the groups in PA / EA. Conclusion The TIMI high score group is closely related to plaque quality, EA, PA, PA / EA and EI, and PA / EA is the most clinically significant.
