Proposed Contrast Volume Limit (ml) in ST-Elevation MI Coronary Angioplasty
Actual Volume of Contrast Given (ml)
Contrast-Induced Nephropathy Risk*
Marenzi G, et al. Contrast Volume During Primary Percutaneous Coronary Intervention and Subsequent Contrast-Induced Nephropathy and Mortality. Ann Intern Med. 2009:150:170-177. (University of Milan). Creatinine = 1.28 ± 0.4 mg% in this study's "High Contrast Ratio" subset. As a result, in this calculator "High Creatinine" is arbitrarily defined by the designer to be >= 1.69 mg% (149 umol/L).
*Contrast-induced nephropathy is increase in serum creatinine >=25% and/or >=0.5 mg/dl (=44 umol/L) after PCI vs. baseline, during the PCI hospitalization. Linearity presumed at contrast ratio of 1 to 4.7.
