Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study aims to create a better way to detect acute kidney injury early after heart surgery. Researchers will combine blood and urine tests with patient information to build a scoring system. The goal is to identify high-risk patients quickly so doctors can take steps to protect their kidneys. The study involves 400 adults scheduled for complex heart surgery.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults undergoing scheduled, combined, cardiac surgery with CEC. * "Combined" cardiac surgery (as opposed to simple cardiac surgery, which is less likely to result in ARF-CC) involves: * 2 heart valves (and possibly other procedures) or ≥2 types of procedures among coronary artery bypass graft(s), valve, myocardial, and thoracic aortic surgery. * A "scheduled" surgical procedure implies that the patient was added to the operative schedule more than 24 hours before the procedure. Exclusion Criteria: * unscheduled cardiac surgery * at least one session of extra-renal purification in the week prior to surgery * Patient refusal to participate in this research, * participation in a study with a possible impact on the incidence of AKI-CC * pregnant woman * minor, adult under guardianship, protected person. * no biomarker concentrations were measured and no clinico-biological scores were determined, * no pre-CEC creatinine assay is available, * the patient dies before H48 unless AKI-CC has occurred in the interim, * the patient withdraws consent to participate in the study.
