Noninvasive Test Predicts Contrast-Induced AKI in Stable Coronary Artery Disease Patients

Bioimpedance vector analysis (BIVA), a noninvasive method for measuring fluid status, could predict the development of contrast-induced AKI in a study of 900 patients scheduled to undergo coronary angiography. Patients in the highest quartile of fluid depletion based on BIVA, which is typically used to monitor fluid volume of patients on dialysis or with heart failure, had a nearly 3-fold higher risk of developing AKI within 3 days after contrast administration. The findings are published in the Journal of the American College of Cardiology.
