Core Tip

Core tip: We investigated the correlation between intracoronary thrombus components and coronary blood flow after stent implantation in direct percutaneous coronary intervention (PCI) in acute myocardial infarction (AMI). A total of 154 patients with direct PCI who underwent thrombus catheter aspiration within < 3, 3-6 or 6-12 h of onset of AMI were included. There was a significant correlation between the onset time of AMI and the occurrence of no reflow and slow blood flow during PCI. In direct PCI, the onset time of AMI and color of coronary thrombus may predict whether there will be no reflow or slow blood flow after stent implantation.
