Contrast-Induced Acute Kidney Injury in ST-Segment Elevation Myocardial Infarction

The goal of this clinical trial is to determine whether a structured oral hydration regimen reduces the incidence of contrast-induced acute kidney injury (CI-AKI) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). The main questions it aims to answer are: Does a structured oral hydration regimen reduce the incidence of CI-AKI compared with standard care without a prescribed hydration regimen? Does oral hydration improve renal outcomes without increasing the risk of adverse events, such as heart failure or fluid overload, in patients undergoing PPCI? Researchers will compare patients receiving a structured oral hydration regimen with patients receiving standard care without a prescribed hydration regimen to determine whether oral hydration decreases the incidence of CI-AKI and improves clinical outcomes. Participants will: Be randomly assigned to either the oral hydration group or the standard care group. Undergo primary percutaneous coronary intervention according to institutional practice. Receive the assigned hydration strategy after the procedure. Have serum creatinine measured at baseline and after contrast exposure to assess for CI-AKI. Be monitored for adverse events, including fluid overload, heart failure, need for renal replacement therapy, length of hospital stay, and other relevant clinical outcomes.
