Matsushita et al. describe a model of acute kidney injury to chronic kidney disease progression in mice surviving cardiac arrest: mice develop severe acute kidney injury that initially recovers but is followed by the onset of impaired renal function on longer-term follow-up. These findings suggest that distinct cardiorenal toxicities and/or injury dynamics are operative in this cardiac arrest model that do not occur in traditional models of acute kidney injury, providing new opportunities for therapeutic and biomarker discovery for an important clinical problem.
