Renal insufficiency identifies higher-risk first-time ICD recipients; leaves open whether GFR staging should guide selection or monitoring.
Does chronic renal insufficiency increase mortality in patients receiving first-time implantable cardioverter-defibrillators?
Pre-implant chronic renal insufficiency is independently associated with a stepwise increase in all-cause mortality among patients receiving first-time ICDs.
