The effect of coronary angiography timing and use of cardiopulmonary bypass on acute kidney injury after coronary artery bypass graft surgery
This retrospective study evaluated the relationship between the timing betweenLHC and CABG and its effect on renal function in a cohort of 2371 patients at a single center. Findings included:
A shorter interval between LHC and CABG was independently associated with postop kidney injury in patients undergoing on-pump CABG, but not in those undergoing OPCAB.
Question: Should the findings of this study influence whether you perform off-pump vs. on-pump CABG if CABG is performed within a week of LHC, independent of other considerations?
Not only acute Kidney injury, even infective complications due to transient bacteraemia following, especially transfemoral, Left heart catheterisation are a cause of concern. A delay of a minimum 3 days helps the dye to flush off nd bacteraemia to clear. Besides it gives the patient enough time to make an informed decision, lest it looks like an ad hoc PCI, which infact as a Class III indication.
