Background—The mechanisms underlying the variation in collateral formation between patients, even with similar patterns of coronary artery disease, remain unclear. This study investigates whether circulating humoral or cellular factors can provide an insight into this variation. Methods and Results—Thirty patients with isolated left anterior descending coronary artery disease underwent percutaneous coronary intervention with collateral flow index (CFI) determined using a pressure wire. Patients…

Risk factors for coronary artery disease, circulating endothelial progenitor cells, and the role of HMG-CoA reductase inhibitors.

The balance of atheroprotective and proatherosclerotic factors may influence EPC levels and their functional capacity to improve neovascularization and endothelial regeneration.

Systemic and intracardiac vascular endothelial growth factor and angiopoietin‐1 and ‐2 levels in coronary artery disease: Effects of angioplasty

There were no differences in indices of angiogenesis when aortic root, coronary ostium, coronary sinus, and femoral vein levels of VEGF and angiopoietins are compared, suggesting that peripheral blood measurements of these indices are comparable to intracardiac levels.

Circulating levels of EPCs are significantly lower in patients with angiographic CAD progression, and the relationship between plasma EPC levels and the 24‐mo progression of the nonsignificant coronary artery lesion is investigated.

Reduced Number of Circulating Endothelial Progenitor Cells Predicts Future Cardiovascular Events: Proof of Concept for the Clinical Importance of Endogenous Vascular Repair

Reduced levels of circulating EPCs independently predict atherosclerotic disease progression, thus supporting an important role for endogenous vascular repair to modulate the clinical course of coronary artery disease.

Endothelial progenitor cells (CD34+KDR+) and monocytes may provide the development of good coronary collaterals despite the vascular risk factors and extensive atherosclerosis.

Endothelial progenitor cells can be mobilized from bone marrow to induce the coronary collateral growth in case of myocardial ischemia even in presence of the vascular risk factors and extensive atherosclerosis.

Circulating Endothelial Progenitor Cells and Coronary Collaterals in Patients with Non-ST Segment Elevation Myocardial Infarction

This study supports an association between circulating EPC levels and collateral formation in patients with an NSTEMI and the relative number of EPCs before PCI was significantly higher in the coll+ group than in thecoll– group.



Number and Migratory Activity of Circulating Endothelial Progenitor Cells Inversely Correlate With Risk Factors for Coronary Artery Disease

Patients with CAD revealed reduced levels and functional impairment of EPCs, which correlated with risk factors for CAD, and hypertension was identified as a major independent predictor for impaired EPC migration.

Circulating endothelial progenitor cells, vascular function, and cardiovascular risk.

In healthy men, levels of endothelial progenitor cells may be a surrogate biologic marker for vascular function and cumulative cardiovascular risk and suggest that endothelial injury in the absence of sufficient circulating progenitors may affect the progression of cardiovascular disease.

Increase in Circulating Endothelial Progenitor Cells by Statin Therapy in Patients With Stable Coronary Artery Disease

A novel mechanism of action of statin treatment in patients with stable CAD is defined: the augmentation of circulating EPCs with enhanced functional activity.

Tissue factor, the emerging link between inflammation, thrombosis, and vascular remodeling.

The importance of TF expression on the development of neointimal growth in response to hemostasis is demonstrated by demonstrating the necessity of fibrin deposition for the smooth muscle cell migration and migration in patients with unstable angina.

Promotion of Collateral Growth by Granulocyte-Macrophage Colony-Stimulating Factor in Patients With Coronary Artery Disease: A Randomized, Double-Blind, Placebo-Controlled Study

This first clinical study investigating the potential of GM-CSF to improve collateral flow in patients with coronary artery disease documents its efficacy in a short-term administration protocol.

Vascular endothelial growth factor-A-induced chemotaxis of monocytes is attenuated in patients with diabetes mellitus: A potential predictor for the individual capacity to develop collaterals.

The cellular response of monocytes to VEGF-A is attenuated in diabetic patients because of a downstream signal transduction defect, and data suggest that monocytes are important in arteriogenesis and that their ability to migrate might be critical to the arteriogenic response.

Effects of coronary artery disease on expression and microvascular response to VEGF.

VEGF and HGF elicit the release of nitric oxide through activation of tyrosine kinase receptors and this findings may have important implications regarding the efficacy of endogenous and exogenous VEGF in patients with risk factor for CAD.

Coronary Collaterals: An Important and Underexposed Aspect of Coronary Artery Disease

The potential of individuals to develop coronary collateral circulation has so far been largely neglected but may play a major role in determining myocardial vulnerability and determinants that play a role in collateral coronary blood supply are proposed.
