Is delayed facilitated percutaneous coronary intervention better than immediate in reperfused myocardial infarction?
Our data suggest the safety and possible use of delayed facilitated PCI in patients with STEMI, and that delayed PCI in patients treated with combined lytic and IIb/IIIa inhibitors appears to be as effective and possibly superior (reduced ischemic events and repeat PCI) as immediate PCI. The patients in this study were successfully reperfused, with TIMI-3 flow and our data may not apply to patients with TIMI 0-2 flow. This strategy could allow transferring the reperfused patients and performing PCI after hours<72 hours and not immediately, thereby reducing the number of urgent PCI and costs, obtaining similar results, but mostly causing less discomfort to the patient. Our results had to be interpreted with caution, because current guidelines do not recommend the combined therapy, but suggest further studies. The study was aimed to investigate the outcomes in patients initially successfully treated pharmacologically and immediate PCI<2 h, and in patients initially successfully treated with pharmacological therapy and delayed PCI (12-72 h). All patients had to have successful reperfusion, to receive the combination of a standard abciximab or tirofiban infusion plus half dose rtPA. Similar results were observed in both groups. Delayed PCI group showed a significant lower incidence in restenosis (0.01), minor bleedings (0.005), ischemic events (0.01) and a reduced angiographic evidence of thrombus formation in IRA (0.001). Our data suggest the safety and possible use of delayed facilitated PCI in patients with STEMI. Our results had to be interpreted with caution, because current guidelines do not recommend the combined therapy, but suggest further studies.
CXCL5 is required for increased intestinal angiogenesis during resection-induced adaptation. Since adaptive villus growth occurs despite impaired CXCL5 expression and enhanced angiogenesis, this suggests that the growth of new blood vessels is not needed for resection-induced mucosal surface area expansion following massive SBR.
