AKI After PCI: Optimizing Contrast Selection for Real‑World Prevention-Iso-Osmolar Iodinated Contrast Agent: Data and Practice, Dr. Mixon

Iso-Osmolar Iodinated Contrast Agent: Data and Practice, Dr. Mixon

Video Transcription

Video Summary

The speaker reviewed contrast agents and the risk of contrast-induced acute kidney injury (AKI), using a 78-year-old woman with non-STEMI and CKD as a case example. He explained that older high-osmolar agents caused more side effects and AKI, while low-osmolar agents reduced risk. The key question was whether iso-osmolar iodixanol offers further protection. Early small trials suggested benefit, but later studies and meta-analyses showed no consistent advantage over most low-osmolar agents, except possibly iohexol and ioxaglate, which appear worse. Current guidelines do not prefer iso- over low-osmolar agents overall. Prevention should focus on hydration, risk assessment, and contrast minimization.
