• In patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI), five simple variables unrelated to the procedure may accurately identify those at increased risk of contrast-associated acute kidney injury (CA-AKI). • Assessing the risk of CA-AKI at the time of hospital admission for STEMI may facilitate the timely implementation of adequate preventive measures and inform patient centered decisions. • Further research is needed to identify optimal hydration protocols and adjunctive therapies aimed a mitigating the risk of CA-AKI after primary PCI.
