Coronary artery disease (CAD) is the main cause of death in patients with chronic kidney disease (CKD). We investigated whether CKD stage affected coronary lesion morphology in patients with established CAD. Coronary angiograms of 264 patients were evaluated. Chronic kidney disease was staged using the estimated glomerular filtration rate (eGFR) from the serum creatinine prior to coronary angiography. Patients were divided into 3 groups: dialysis or severe decrease in GFR <30 mL/min per 1.73 m(2) (group 1; n = 60), patients with moderate kidney failure (group 2; n = 116), and patients with normal renal function or mild decrease in GFR (group 3; n = 88). The likelihood of CAD and lesion complexity increased with decreasing eGFR (P = .001). Patients with CKD also had more significant CAD. The risk of significant coronary obstruction and lesion complexity increased progressively with decreasing eGFR. The eGFR may predict lesion complexity among patients with CKD undergoing coronary angiography.
