About this study

Official title: Predicting Acute Kidney Injury After Coronary Artery Bypass Graft : a Simplified Clinical Risk Scoring Model

Acute kidney injury after cardiac surgery is a major complication after cardiac surgery and has been reported to be associated with adverse outcome. There have been many studies reporting risk factor of acute kidney injury after cardiac surgery, but the influence of perioperative variables related to anesthesia and perioperative medication has not been evaluated fully. The investigators attempt to evaluate the influence of perioperative clinical variables including preoperative medication, preoperative albumin level, uric acid concentration, anesthesia technique, use of hydroxyethyl starch, blood glucose level, intraoperative medication, perioperative cardiac function (systolic and diastolic function) and hemodynamic variables during surgery on the incidence of acute kidney injury after coronary artery bypass graft.

Read the detailed description

Acute kidney injury (AKI) after cardiac surgery is a major complication after cardiac surgery and has been reported to be associated with adverse outcome. There have been many studies reporting risk factor of acute kidney injury after cardiac surgery, but the influence of perioperative variables related to anesthesia and perioperative medication has not been evaluated fully. The investigators attempt to evaluate the influence of preoperative medication, preoperative albumin level, uric acid concentration, NL ratio, anesthesia technique, use of hydroxyethyl starch, blood glucose level, intraoperative medication, perioperative cardiac function (systolic and diastolic) and hemodynamic variables during surgery on the incidence of acute kidney injury after coronary artery bypass graft. Preoperative and postoperative diastolic dysfunction may be associated with postoperative AKI. In addition, preoperative neutrophil-lymphocyte ratio (NLR) which has been reported to be a marked for systemic inflammation and was associated with prognosis in cardiac patients undergoing coronary artery bypass graft or percutaneous coronary intervention. This preoperative or immediate postoperative NLR might be able to predict AKI after coronary artery bypass surgery.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Acute kidney injury diagnosis defined by KDIGO criteria

    Acute kidney injury diagnosis defined by KDIGO criteria (Stage 1, 2, 3) during seven days after surgery

    Measured: during 7 days after surgery

Secondary outcomes (1)
  1. Acute kidney injury as defined by AKIN (acute kidney injury network) criteria

    Acute kidney injury as defined by AKIN (acute kidney injury network) criteria

    Measured: within 48 hours after surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Coronary Artery Bypass Surgery and Acute Kidney Injury, run by Samsung Medical Center at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Acute kidney injury diagnosis defined by KDIGO criteria (time frame: during 7 days after surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Jun 2016.
