CSF3 and acute myocardial infarction: The Gregorio Marañón Hospital in Spain is running a Phase 2 clinical trial (NCT00984178: Trial of hematopoietic stem cells in acute myocardial infarction [TECAM2]) to compare the effectiveness of four strategies to prevent postinfarction ventricular remodeling: conventional treatment for reperfused extensive acute myocardial infarction; intracoronary transplantation of autologous bone marrow stem cells; mobilization of bone marrow stem-cells induced by G-CSF; and the combination of stem-cell transplantation with G-CSF-induced mobilization.
