Treatment with granulocyte-colony stimulating factor (G-CSF) mobilises cells from the bone marrow to the peripheral blood. Previous preclinical and early clinical trials may suggest that treatment with G-CSF leads to improved myocardial perfusion and function in acute or chronic ischaemic heart disease. In the REVIVAL-2 study we found that stem cell mobilisation by G-CSF does not influence infarct size, left ventricular function and coronary restenosis in patients with acute myocardial infarction (MI) that underwent successful percutaneous coronary intervention. The objective of the present analysis was to assess the impact of G-CSF treatment on seven-year clinical outcomes from the REVIVAL-2 trial. In the randomized, double-blind, placebo-controlled REVIVAL-2 study, 114 patients with the diagnosis of acute myocardial infarction were enrolled five days after successful reperfusion by percutaneous coronary intervention. Patients were assigned to receive 10 µg/kg G-CSF (n=56) or placebo (n=58) for five days. The primary endpoint for this long-term outcome analysis was the composite of death, myocardial infarction or stroke seven years after randomisation. The endpoint occurred in 14.3 % of patients in the G-CSF group versus 17.2 % assigned to placebo (p=0.67). The combined incidence of death or myocardial infarction occurred in 14.3 % of the patients assigned to G-CSF and 15.5 % of the patients assigned to placebo (p=0.85). In conclusion, these long-term follow-up data show that G-CSF does not improve clinical outcomes of patients with acute myocardial infarction.     «
