title: Circulating endothelial progenitor cells as a link between synovial vascularity and cardiovascular mortality in rheumatoid arthritis.
abstract: Cardiovascular disease refers to the class of diseases that involve the heart and/or blood vessels (arteries and veins). Most Western countries face high and ever-increasing rates of cardiovascular disease. Each year, more Americans are killed by heart disease than by cancer. Diseases of the heart alone cause 30% of all deaths, with other diseases of the cardiovascular system causing substantial further deaths and disability. Indeed, cardiovascular disease is the major cause of death and disability in the USA and most European countries. The development of the vascular systems requires an intricate interplay of molecules such as vascular endothelial growth factor and endothelial progenitor cells. A defective vascular repair/regeneration is thought to be responsible for propagation of atherosclerosis, a key feature of cardiovascular disease. This is partly attributed to a reduction in the circulating endothelial progenitor cells in peripheral blood. Patients with rheumatoid arthritis (RA) have a higher than average incidence of cardiovascular disease in comparison with the general population, with an increased risk of stroke and myocardial infarction, and an increased risk of fatality following myocardial infarction. This review focuses on the current evidence linking the role played by endothelial progenitor cells to the development of cardiovascular disease and why this might relate to the increased risk observed in RA patients.
