Randomized Controlled TrialEffects of stem cell mobilization by granulocyte colony-stimulating factor on endothelial function after sirolimus-eluting stent implantation: a double-blind, randomized, placebo-controlled clinical trial.
Stem cell mobilization by granulocyte colony-stimulating factor (G-CSF) has been shown to enhance endothelial healing after spontaneous or iatrogenic arterial disruption. Granulocyte colony-stimulating factor treatment might attenuate endothelial dysfunction after sirolimus-eluting stent (SES) implantation that may be associated with adverse cardiac events during follow-up. This prospective, double-blind, randomized, placebo-controlled study investigated whether G-CSF improved endothelial dysfunction after SES implantation. ⋯ Granulocyte colony-stimulating factor attenuates endothelial dysfunction after SES implantation.

Randomized Controlled Trial Comparative StudyClosed versus open cell stent for high-risk percutaneous coronary interventions in ST-elevation acute myocardial infarction: the Closed versus Open Cells stent for High risk percutaneous coronary Interventions in ST-Elevation acute myocardial infarction (COCHISE) pilot study.
Stent deployment may be associated with distal embolization and slow flow in coronary thrombotic lesions. There are no data on the risk of distal thrombus embolization according to the stent design. The aim was to evaluate coronary flow after percutaneous coronary interventions (PCI) in acute myocardial infarction according to the employed stent (closed versus open cell design). ⋯ The use of a closed cell stent design rather than an open cell during PCI for acute ST-elevation myocardial infarction is associated with better coronary angiographic flow after PCI.
