Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be referred by their primary cardiologist. Once enrolled, subjects will be randomised to either G-CSF followed by placebo or Placebo followed by G-CSF therapy. This allocation will be concealed from both patient and the investigator responsible for patient enrolment and subsequent patient reviews. The allocation schedule will be held by Pharmacy.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomisation table
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Crossover
Other design features
Subjects and the doctors in direct contact with subjects will be blinded.

Summary
Brief summary
Angina is a medical term used to describe pain (usually felt in the chest) due to coronary artery disease causing reduced blood flow to the heart. We are investigating the use of G-CSF to treat chronic angina in patients who have failed standard treatment with medications and or coronary stenting/coronary artery bypass surgery. G-CSF is a man made version of a naturally occuring hormone. There is experimental evidence that G-CSF can stimulate the formation of new blood vessels in the heart and protect heart muscle cells. Through these effects, we hypothesise that patients will derive improvements in blood flow to the heart and hence angina symptoms. We will be measuring the effects of G-CSF on blood flow to the heart with cardiac magnetic resonance imaging (MRI scan).
