RENAL FUNCTION-BASED CONTRAST DOSING TO DEFINE “PROGNOSTIC” CONTRAST DOSE LIMITS FOR PERCUTANEOUS CORONARY INTERVENTION – THE PROGNOSTIC IMPLICATION OF THE CONTRAST VOLUME: GLOMERULAR FILTRATION RATIO IN 44,082 PATIENTS FROM THE BRITISH COLUMBIA CARDIAC REGISTRY

Background: Renal function-based contrast dosing to limit renal injury following percutaneous coronary intervention (PCI) has been studied but its prognostic relevance is unknown. We evaluated the contrast volume: glomerular filtration rate (GFR) ratio (R) to define “prognostic” limits for
