Abstract
Comparative clinical outcomes after exposure to alternate low osmolar contrast media (LOCM) during invasive coronary angiography (ICA) and/or percutaneous coronary intervention (PCI) have been incompletely examined. From a retrospective multicenter observational study, we identified 107,994 adults without previous hemodialysis undergoing ICA and/or PCI with iohexol, iopamidol, or ioversol. We created a propensity score for contrast media type using age, gender, coverage status, route of hospitalization, illness severity, physician specialty, co-morbidities, and procedure type. Propensity matching was performed in a 1:1 fashion for iohexol (n = 10,204) and iopamidol (n = 10,204) and in a 1:1 fashion for iohexol (n = 19,482) and ioversol (n = 19,482). Groups were examined for differences in in-hospital mortality or subsequent hemodialysis, length of stay, and 30-day readmission for contrast-induced nephropathy (CIN). Compared to patients exposed to iohexol, no differences were observed for patients exposed to iopamidol or ioversol for in-hospital hemodialysis (0.5% vs 0.4%, p = 0.45; 0.3% vs 0.5%, p = 0.05), in-hospital mortality (0.7% vs 0.6%, p = 0.60; 0.5% vs 0.6%, p = 0.42), or composite hemodialysis or mortality (1.1% vs 1.0%, p = 0.58; 0.8% vs 1.0%, p = 0.06); for hospital length of stay (2.9 ± 2.7 vs 2.9 ± 2.7 days, p = 0.05; 2.8 ± 2.6 vs 2.9 ± 3.1 days, p = 0.35); or for 30-day readmission for CIN (0.1% vs 0.1%, p = 0.82; 0.1% vs 0.1%, p = 0.52). In conclusion, for patients undergoing ICA and/or PCI exposed to alternate LOCM, in-hospital death, need for hemodialysis, or readmission for CIN are uncommon, with no apparent clinical advantage among LOCM agents.
