Implication

Randomized trial examines CI-AKI risks in emergency angiography, suggesting pre-procedural hydration to mitigate risks.

Key Points

  • This research aims to evaluate the incidence and outcomes of contrast-induced acute kidney injury (CI-AKI) in patients undergoing emergency coronary angiography.
  • Prospectively monitored renal function in 302 consecutive patients for 18 months.
  • Defined CI-AKI using KDIGO criteria and assessed outcomes such as hospital stay and mortality.
  • Utilized the Mehran risk score for risk stratification and analysis of CI-AKI incidence.
  • CI-AKI occurred in 44 patients (14.6%), with a range across stages: stage 1 (9.3%), stage 2 (4.0%), and stage 3 (1.3%).
  • Increased CI-AKI incidence from 3.2% in the lowest to 41.7% in the highest risk using the Mehran score (AUC 0.81, 95% CI 0.74-0.88).
  • Patients with CI-AKI had longer hospital stays (median 10 vs 5 days), higher in-hospital mortality (9.1% vs 1.9%), and higher new dialysis needs (9.1% vs 0%).
