The Value of CTFC in Patients with Acute Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention and Effect of Adenosine Interference on CTFC / 中国医师杂志

ABSTRACT

Objective To assess the value of corrected TIMI frame count(CTFC) in patients with acute myocardial infarction(AMI) underwent primary percutaneous coronary intervention(PCI) and the change of CTFC before and after adenosine interference. Methods CTFC was defined as the number of cineframes from coronary filling with radiographic reagent to visualization of distal coronary landmark in the infarct-related artery. Normal antegrade flow was 0.05), and CTFC of the patients with slow antegrade flow, who underwent PCI, was not significantly different before and after administering adenosine. LVEF of the patients with normal antegrade flow was significantly higher than that of the patients with slow antegrade flow(P=0.001). MACE of the patients with slow blood flow were obviously higher than that of the patients with natural blood flow(P
