摘要(Abstract)：
目的 观察急性心肌梗死患者经皮冠状动脉介入 (PCI)治疗成功后 ,即TIMI血流达到 3级时 ,用校正的TIMI帧数 (CTFC)评价心肌组织水平灌注的可行性。方法 选取急性心肌梗死患者急症PCI治疗后血流达TIMI 3级者 6 3例 ,其中男 4 5例 ,女 18例。测定患者的CTFC ,并在术前及术后 1个月分别测定室壁运动记分 (WMSI)。观察CTFC与WMSI之间的相关性。结果 按照CTFC将TIMI血流 3级者分为快、慢两组 ,1个月后快CTFC组的WMSI改善程度明显优于慢CTFC组 ,CTFC与术前、术后WMSI的差值有明显的负相关 ;快CTFC组患者从发病到接受PCI治疗的时间明显短于慢CTFC组。结论 较低的CTFC预示着良好的心功能恢复及临床预后 ,它是一种定量、客观、简单、经济、重复性好的方法 ,用其评价心肌循环灌注情况可为临床提供是否需要进一步辅助治疗的证据。
