Background: To evaluate renal function, the indices of estimated glomerular filtration rate (eGFR) obtained using several equations, including the Japanese versions of the serum creatinine-based MDRD equation (eGFRcreat), Chronic Kidney Disease Epidemiology Collaboration equation (eGFR-EPI), and serum cystatin C-based equation (eGFRcys), are utilized. This study prospectively examined the association between these eGFR values and all-cause mortality during a 12-year observational period in a community-based population.
Methods And Results: The subjects of this study were 1312 participants undergoing a health checkup, aged ≥40 years.
Background: Chronic kidney disease is a significant risk factor for end-stage kidney disease, cardiovascular events, and premature death. However, the prognostic value of low estimated glomerular filtration rate (eGFR) in the elderly is debatable.
Methods: We determined eGFR using the Japanese equation in 132,160 elderly subjects (65-75 years) who attended the special health checkup (Tokutei-Kenshin) in 2008 and investigated the association between baseline eGFR and 5-year all-cause and cardiovascular mortality.
