Recommendations for Chronic Kidney Disease

2007 Recommendations2011 Focused Update RecommendationsComments
Class I
    CrCl should be estimated in UA/NSTEMI patients, and the doses of renally cleared drugs should be adjusted appropriately. (Level of Evidence: B)1. CrCl should be estimated in UA/NSTEMI patients and the doses of renally cleared medications should be adjusted according to the pharmacokinetic data for specific medications.155,156 (Level of Evidence: B)Modified recommendation (changed wording for clarity).
    In CKD patients undergoing angiography, isosmolar contrast agents are indicated and are preferred. (Level of Evidence: A)Deleted recommendation.
2. Patients undergoing cardiac catheterization with receipt of contrast media should receive adequate preparatory hydration.157,158 (Level of Evidence: B)New recommendation
3. Calculation of the contrast volume to CrCl ratio is useful to predict the maximum volume of contrast media that can be given without significantly increasing the risk of contrast-associated nephropathy.159,160 (Level of Evidence: B)New recommendation
Class IIa
1. An invasive strategy is reasonable in patients with mild (stage II) and moderate (stage III) CKD.155,156,161,162 (Level of Evidence: B) (There are insufficient data on benefit/risk of invasive strategy in UA/NSTEMI patients with advanced CKD [stages IV, V].)Modified recommendation (class changed from IIb to IIa, level of evidence changed from C to B, and moved from Section 3.3).
