Risk-Stratified Prognostic Implications of Contrast-Associated Acute Kidney Injury After Percutaneous Coronary Intervention.

ABSTRACT:

Background

The clinical importance of contrast-associated acute kidney injury (CA-AKI), the most common complication after percutaneous coronary intervention (PCI), is debated.

Objectives

We aimed to assess the association between CA-AKI and long-term outcomes, overall and across the National Cardiovascular Data Registry (NCDR) AKI risk categories.

Methods

We analyzed patients undergoing PCI between September 2008 and October 2021 from a Japanese registry aligned with the NCDR and categorized them by the NCDR AKI risk score tertiles (low-risk [<4.9%], intermediate-risk [4.9%-6.7%], and high-risk [≥6.7%]) groups. CA-AKI was defined as a 0.3 mg/dL increase or 50% increase in creatinine or the initiation of dialysis. Cox regression analyses assessed the association betwe
