Preventing Stroke in Patients With Chronic Kidney Disease and Atrial Fibrillation

AHA Stroke: September 5, 2013

Chronic kidney disease (CKD) is a major global health problem. It is defined by decreased kidney function (characterized by a reduced estimated glomerular filtration rate [eGFR] <60 mL/min per 1.73 m²) and kidney damage characterized by albuminuria or proteinuria.¹ To standardize definitions and facilitate risk stratification, 5 different stages of severity have been defined by the National Kidney Foundation in 2002: CKD stage 1 with a normal eGFR ≥90 mL/min per 1.73m² but proven proteinuria, CKD stage 2 with eGFR 60 to 89 mL/min per 1.73 m², CKD stage 3 with eGFR 30 to 59 mL/min per 1.73 m², CKD stage 4 with eGFR 15 to 29 mL/min per 1.73 m², and CKD stage 5 with eGFR <15 mL/min per 1.73 m². Read More
