Aims To investigate the risk prediction and the risk stratification performances of the Chronic Kidney Disease Epidemiology Collaboration ( CKD- EPI) equation and the Modification of Diet in Renal Disease ( MDRD) equation for estimated glomerular filtration rate ( eGFRCKD- EPI vs. eGFRMDRD) on heart failure in patients with Type 2 diabetes. Methods The study cohort included 12 258 White and 16 886 African American low-income patients with Type 2 diabetes who were 30-90 years old at baseline. Heart failure risk according to different eGFRCKD- EPI and eGFRMDRD categories was prospectively assessed. Results During a mean follow-up of 6.5 years, 5043 incident heart failure cases were identified. Multivariable-adjusted hazard ratios ( HRs) of heart failure associated with the eGFRCKD- EPI categories [≥ 90 (reference group), 75-89, 60-74, 30-59 and < 30 ml/min/1.73 m2] were 1.00, 1.11, 1.31, 1.75 and 2.93 ( Ptrend < 0.001) for African American patients, and 1.00, 1.11, 1.08, 1.59 and 2.92 ( Ptrend < 0.001) for White patients, respectively. The model with eGFRCKD- EPI and the other risk factors had significantly higher Harrell's C than the model with eGFRMDRD and other risk factors. Patients reclassified downward from eGFRMDRD 60-74 to eGFRCKD- EPI 30-59 and from eGFRMDRD 30-59 to eGFRCKD- EPI < 30 ml/min/1.73 m2 showed higher heart failure risk than those who were not reclassified. Conclusions Impaired kidney function (i.e. GFR < 60 ml/min/1.73 m2), and even mildly decreased GFR (60-74 ml/min/1.73 m2) estimated by both equations is associated with an increased risk of heart failure. Compared with GFR estimated using the MDRD equation, GFR estimated using the CKD- EPI equation added more predictive power to the model with the other risk factors. Also, eGFRCKD- EPI provided more accurate heart failure risk stratification than eGFRMDRD . [ABSTRACT FROM AUTHOR]
