This Journal feature begins with a case vignette highlightinga common clinical problem. Evidence supporting various strategiesis then presented, followed by a review of formal guidelines,when they exist. The article ends with the authors' clinicalrecommendations.
A 71-year-old man with type 2 diabetes and hypertension is referredfor coronary angiography. His medications include metforminand a thiazide. Before the angiogram, his serum creatinine levelis 1.8 mg per deciliter (160 µmol per liter), yieldingan estimated glomerular filtration rate of 40 ml per minuteper 1.73 m2 of body-surface area. What can be done to reducethe risk . . . [Full Text of this Article]
