Renal artery stenosis in patients with established coronary artery disease: prevalence and predicting factors.

The association between renal artery stenosis (RAS) and other atherosclerotic diseases (particularly coronary artery diseases) is well known. In general, the risk factors for atherosclerosis have been clarified, but whether these risk factors operate equally in all forms of atherosclerotic diseases is not known. The aim of this study was to describe the prevalence of RAS in patients with established coronary artery diseases and then to define the most important risk factors that may help to predict the RAS in this population.
