摘要
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。
Objective To study the probability of evaluating myocardial tissue perfusion by corrected TIMI frame count (CTFC) after successful percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods Sixty-three patients with their first acute myocardial infarction (AMI) who accepted primary coronary intervention were recruited. All these patients got TIMI 3 grade flow. CTFC was measured after successful PCI in these patients. Wall Motion Score Index (WMSI) assessed by two-dimensional echocardiography before and one month after PCI and the correlation studied between CTFC and WMSI. Results According to CTFC the patients were divided into two groups. Improvement of WMSI in the TIMI 3 fast group was significantly greater than that of the TIMI 3 slow group. CTFC had a significant correlation with the change in WMSI. Elapsed time from the onset of symptoms to reperfusion in the TIMI slow group was significantly longer than that of the TIMI fast group. Conclusion CTFC is a quantitative, and reproducible index of coronary blood flow. Lower CTFC is associated with greater functional recovery and could supply evidence for additional adjunctive treatment.
