Which calculation method of glomerular filtration rate is suitable in patients with normal or mildly impaired renal function?

摘要

We read the article entitled "Association of Glomerular Filtration Rate With Slow Coronary Flow in Patients With Normal to Mildly Impaired Renal Function" by Akin et al with interest. The authors1 concluded that estimated glomerular filtration rate (eGFR) was significantly correlated with slow coronary flow in patients with normal to mildly impaired kidney function.The Kidney Disease: Improving Global Outcomes organization developed clinical practice guidelines in 2012, recommending that the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation is used for reporting eGFR, particularly in patients with a GFR > 60 mL/min/1.73 m~2. Compared with the Modification of Diet in Renal Disease (MDRD) equation, the CKD-EPI equation may be more accurate in patients with measured3 GFR > 60 mL/min/1.73m~2.
