Study of Preoperative HbA1c and Kidney Function Changes After Isolated Coronary Artery Bypass Surgery Observing Acute Kidney Injury Using Doppler Renal Resistive Index and KDIGO Criteria

What This Trial Is About

Renal complications are common in cardiac surgery and often appear as acute kidney injury AKI, which can lead to serious health issues. This research aims to understand how preoperative hemoglobin A1c HbA1c levels and Doppler-derived renal resistive index RRI relate to the development of AKI after isolated coronary artery bypass grafting. The study focuses on patients undergoing this surgery to explore these relationships using established kidney injury criteria and imaging methods. Participants will have their HbA1c levels measured within 7 days before surgery and undergo Doppler RRI assessments within 24 hours before and after the procedure. The study observes isolated coronary artery bypass graft surgery patients, collecting data on kidney function changes defined by KDIGO criteria at 48 hours and 7 days post-surgery. This observational study does not involve treatment interventions but follows patients through their surgical and recovery periods. Throughout the study, patients kidney function will be monitored using blood tests and Doppler ultrasound imaging. Researchers will evaluate the correlation between preoperative HbA1c, RRI values, and postoperative kidney injury stages. Additional outcomes include length of stay in intensive care and the hospital. Participants will be observed up to three months post-surgery to assess these outcomes and gather comprehensive data on kidney health and recovery.
