Kofman N, et al. - In this retrospective study of 225 consecutive ST elevation myocardial infarction (STEMI) patients who developed acute kidney injury (AKI), researchers determined the incidence and prognostic implications of acute kidney disease (AKD), defined as reduced kidney function for the duration of between 7 and 90 days after exposure to an AKI initiating event, as well as long-term renal outcomes. Outcomes showed that following an acute renal insult, progression to AKD was frequent in STEMI and associated with worse survival and adverse long-term renal outcomes.
