Objective: Renal dysfunction represents a risk factor for poor coronary collateral growth. We investigated whether Glomerular Filtration Rate (GFR) estimated with the cystatin C-based formula (GFRCYS) is superior to that with the creatinine-based abbreviated Modification of Diet in Renal Disease (GFRMDRD) and the Chronic Kidney Disease Epidemiology Collaboration (GFREPI) equations for evaluating coronary collateralization in type 2 diabetic patients with stable coronary artery disease. Methods: GFR was estimated with creatinine- and cystatin C- based equations in 302 diabetic and 127 nondiabetic patients with stable angina and angiographic total occlusion of at least one major coronary artery. The degree of collaterals supplying the distal aspect of a total occlusion from the contra-lateral vessel was graded as poor (Rentrop score of 0 or 1) or good c.. View More»
