'CIN' no more: The use of contrast volume to e-GFR ratio to predict and prevent contrast-induced acute kidney injury

摘要

We read with interest the study from Mager et al., which examined the relationship between contrast volume to estimated glomerular filtration rate (eGFR) ratio, and clinical outcomes in patients with ST-elevation myocardial infarction (STEMI) who had undergone primary percutaneous coronary intervention (PCI). Contrast-induced acute kidney injury or contrast-induced nephropathy (CIN) is an important and not rare complication in patients undergoing PCI or diagnostic modalities involving contrast media. This complication has become a significant source of hospital morbidity and mortality with the ever-increasing use of contrast media in diagnostic and therapeutic procedures. With no specific treatment for CIN, identification and stratification of patient risk and preventative measures are paramount.
