Official title
Early Postoperative L-arginine and Acute Kidney Injury After Cardiac Surgery: a Target Trial Emulation
Overview
Acute kidney injury (AKI) is common after cardiac surgery, yet effective protective strategies remain limited. L-arginine is the substrate for endogenous nitric oxide (NO) synthesis and may improve renal perfusion and endothelial function. investigators emulated a target trial to evaluate whether early perioperative L-arginine was associated with a lower risk of AKI after cardiac surgery.
Interventions
- Drug L-arginine
Initiation of L-arginine within 3 postoperative days
Primary outcome measures
- Acute kidney injury [Time frame: within 7 postoperative days]
Secondary outcome measures (2)
- Acute kidney injury stage [Time frame: within 7 postoperative days]
- in-hospital mortality. [Time frame: up to 48 weeks]
