Expression data from monocytes of individuals with different collateral flow index CFI

using peripheral blood monocytes to identify marker genes for an extensively grown coronary collateral circulation. We used microarrays to detail the global programme of gene expression underlying collateralization and identified distinct classes of differently regulated genes during this process. Keywords: observational study Collateral flow index (CFI) was obtained invasively by angioplasty pressure sensor guidewire, a group of patients with coronary artery disease CAD and a group without CAD were selected for peripheral monocyte isolation, RNA extraction and hybridization on Affymetrix microarrays.
