Identifying risk factors for kidney injury after heart surgery

PrEcision Medicine in the Management of Cardiovascular Surgery Associated AKI - PEAK: a Prospective Observational Cohort Study

Observational Insel Gruppe AG, University Hospital Bern · NCT06471621

This study is trying to find out what factors can help predict kidney problems after heart surgery in adults so that doctors can better understand who might be at risk.

What this trial studies

This observational study aims to define a risk profile for acute kidney injury (AKI) associated with cardiovascular surgery by analyzing clinical characteristics, operation parameters, and laboratory values. It seeks to determine if a combination of these factors can better predict patient outcomes compared to traditional risk factors. Participants include adults scheduled for elective heart or major artery surgery, and data will be collected before, during, and after the surgery to identify potential biomarkers and predictors of AKI. The study emphasizes the importance of frailty as a risk factor, alongside classical predictors like age and pre-existing kidney conditions.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and above scheduled for elective cardiovascular surgery.

Not a fit: Patients with a kidney transplant or those on renal replacement therapy will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved prediction and management of acute kidney injury in patients undergoing cardiovascular surgery.

How similar studies have performed: Previous observational studies have indicated the significance of frailty and other biomarkers in predicting AKI, suggesting that this approach may yield valuable insights.
