CONCLUSION
ACKD is independently associated with higher mortality in patients
undergoing PCI. Therefore, PCI in these patients should be performed
with more caution.
LIMITATIONS: We used ICD-9 coding with inherent limitations as
administrative coding has limitations in inaccuracy. We studied patients
who underwent PCI which introduces selection bias as many patients with
ACKD may have been treated conservatively limiting our patients to a
specifically selected group undergoing PCI based on the patient’s
presentation and preference.
