About this study

Aim1a: Statin naive patient's scheduled for cardiac surgery will be randomized to 80mg atorvastatin or placebo on the day prior to surgery and then 40mg daily thereafter until hospital discharge to test the hypothesis that short-term atorvastatin use decreases:

  1. acute kidney injury following cardiac surgery.
  2. postoperative delirium following cardiac surgery.

Aim1b: Patients using statins preoperatively will be randomized to atorvastatin 80mg or placebo on day of surgery and 40mg or placebo on postop day 1 with resumption of preoperative statin therapy on postop day 2 to test the hypothesis that short-term atorvastatin use decreases:

  1. acute kidney injury following cardiac surgery.
  2. postoperative delirium following cardiac surgery.

Endpoints include glomerular filtration, urine and plasma markers of renal dysfunction, markers of oxidative stress, mitochondrial function, systemic inflammatory markers, delirium, dialysis, stroke, myocardial infarction, time to extubation, ICU length of stay, and death.

Questions about this trial

What is this clinical trial studying?

A study testing atorvastatin in people with Acute Kidney Injury and Post-Operative Delirium, run by Vanderbilt University Medical Center at 1 site in United States.

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 9 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 Sep 2019. 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 United States. 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. Some participants in this study may receive a placebo. 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?

Yes. Results are posted in the registry (first posted 6 Mar 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With Acute Kidney Injury (time frame: postoperative day 2). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00791648, which also lists 3 linked publications.

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 Sep 2019.
