The purpose of this trial is to investigate the effect of treatment with granulocyte-colony stimulating factor (G-CSF) bone marrow stimulation on circulating stem cells' ability to develop new blood vessels in the myocardium after an acute myocardial infarction.

Primary Outcome Measures:
  • The pre-specified primary endpoint is change in regional systolic wall thickening from day 1 to day 180 evaluated with cardiac magnetic resonance imaging (MRI)

Secondary Outcome Measures:
  • Change in ejection fraction, end-systolic and end-diastolic volumes, regional myocardial perfusion, and infarct size by MRI
  • Change in regional myocardial function by tissue Doppler echocardiography

Estimated Enrollment: 78
Study Start Date: May 2003
Study Completion Date: February 2006
Primary Completion Date: February 2006 (Final data collection date for primary outcome measure)
Detailed Description:

Intracoronary infusion of bone-marrow stem cells after a ST elevation myocardial infarction (STEMI) seems to improve cardiac function. An alternative strategy is increase of circulating stem cells by mobilisation from the bone marrow with Granulocyte-Colony Stimulating Factor (G-CSF).

Objective: To determine the short-term (30 days) safety of G-CSF therapy after a STEMI treated with acute percutaneous coronary intervention (PCI).

Methods: Patients with STEMI treated with PCI <12 hours after symptom onset were randomised (1:1) to G-CSF (10 μg/kg/d) or placebo for 6 days in a double-blind design. Other inclusion criteria: age 20-70 years, culprit lesion in a large coronary artery, and peak CKMB >100 microgram/L. Follow-up was done after 1, 5 and 6 months, with an angiogram at 5 months.

Ages Eligible for Study:   20 Years to 70 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients between 20 and 70 years with STEMI were eligible if they had a successful PCI within 12 hours after onset of symptoms.
  • The target lesion had to be located in the proximal section of the left anterior descending (LAD), left circumflex (LCX) or right coronary artery (RCA).
  • Only patients with creatine kinase [CK]-MB >100 microgram/L or development of Q waves in the electrocardiogram were included.

Exclusion Criteria:

  • Ventricular arrhythmia after PCI requiring treatment
  • Pregnancy
  • Unprotected left main stem lesion
  • History of prior myocardial infarction
  • Diagnosed or suspected cancer
  • New York Heart Association (NYHA) class 3-4
  • Known severe claustrophobia
  • Significant stenosis in another coronary vessel than the acutely treated vessel, that might demand treatment with PCI or coronary artery bypass graft surgery (CABG) prior to the last follow-up exam.
