校正TIMI帧数对急性心肌梗死病人支架成形术后的预后评价

Corrected TIMI Frame Count Immediately after Primary Coronary Angioplasty as a Predictor of Clinical Outcome in Patients with TUMI 3 Reperfused Acute Myocardial Infarction

目的:观察急性心肌梗死(AMI)病人成功冠状动脉介入(Percutaneous coronary intervation,PCI)治疗后,校正TIMI帧数(Corrected TIMI Frame Count,CTFC)与其预后的关系。方法:选取成功PCI术后、梗死相关动脉TIMI血流3级的AMI病人123例,测定CTFC,同时观察住院期间不良事件的发生率及随访1年时死亡率。结果:根据CTFC值将病人分为慢、快两组。慢CTFC组住院期间不良事件发生率及随访1年时死亡率明显高于快CTFC组,两组具有显著性差异(P值分别为<0.01和<0．05)。结论:CTFC可有效评价成功PCI术后病人近、远期预后,有助于对此类病人进行进一步的危险度分层,以指导治疗。

Objective： To investigate the relation of corrected TIMI frame count immediately after primary coronary angioplasty and clinical outcome in patients With TIMI 3 repeffused acute myocardial infarction.Methods： CTFC were measured immediately after successful PCI in 123 patients with TIMI 3 reperfused acute myocardial infarction. In - hospital adverse events and one - year mortality were investigated.Results： According to CIFC the patients were divided into two groups： TIMI 3 slow group and TIMI 3 fast group. The incidence of in - hospictal adverse events and one - year mortality in the TIMI 3 slow group is higher significantly than in the TIMI 3 fast group（P 〈 0.01 and P 〈 0.05, respectively） . Conclusion： CTFC of the infarct - related artery immediately after successful PCI can predict short - term and long - term clinical outcome in patients with successful PCI,which helps further risk stratification of these patients.
