摘　　要：【目的】探讨前壁巨大倒置T波伴或不伴R波急性冠脉综合征患者的临床特点。【方法】比较前壁巨大倒置T波伴R波（A组）与不伴R波（B组）急性冠脉综合征患者的临床资料与冠脉造影结果，并探讨两者之间的关系。【结果】两组患者基本临床特征无差异，A组较B组患者有更小左室舒张末期容积（LVEDD）与更好左室收缩功能（LVEF）（P〈0．05），A组与B组患者在冠脉病变支数与多支病变方面无显著性差异（P〉0．05），但是，A组较B组患者前降支（LAD）有更多TIMI3级血流与更好的侧支循环（P〈0．05）。【结论】A组较B组患者有更好左室功能，其可能与A组较B组患者前降支（LAD）有更多TIMI3级血流及更好的侧支循环有关。[Objective] To compare the clinical data and angiographic results of patients with acute coro- nary syndrome and giant T-wave inversion with（group A） or without（group B） R-wave in precordial leads, and to explore their relationship. [Methods]Clinical data and angiographic results were compared between group A（ n =26） and group B（ n = 27）. [Results] There was no difference in basic clinical characteristics be- tween two groups. Compared with group I3, group A had smaller left ventricular end-diastolic dimension （LVEDD） and better left ventricular ejection fraction（LVEF）. There was no difference in number of diseased coronary arteries and multivessel disease between two groups. Compared with group B, group A had TIMI grade 3 flow of left anterior descending coronary artery（LAD） with more TIMI grade 3 flow and better collat- eral circulation. [Conclusion]Left ventricle function in group A is better than that in group B, which may he related to LAD with more TIMI grade 3 flow and better collateral circulation in group A compared with group B.
