ClinConnect Summary

This clinical trial is studying the relationship between a test called the Renal Resistive Index (RRI) and a condition known as Acute Kidney Injury (AKI) in patients undergoing heart surgery with a technique called cardiopulmonary bypass (CPB). AKI is a common and serious complication that can occur after heart surgery and may lead to more health problems or even increased risk of death. The traditional way to check for kidney issues is through a blood test for creatinine, but this can have limitations. The RRI test, which is done using ultrasound and does not involve any invasive procedures, may help doctors identify kidney problems earlier, which could prevent AKI from becoming more severe.

To participate in this trial, individuals need to be at least 19 years old and scheduled for heart surgery that involves CPB. However, those who are in emergency situations, have severe kidney issues, or certain other health conditions may not be eligible. Participants in the trial can expect to undergo the RRI test during their treatment, which could help improve the understanding and management of kidney health in heart surgery patients. This study is not yet recruiting participants, but it aims to provide valuable insights that could lead to better outcomes for patients in the future.
