About this study

Several studies have highlighted the cardioprotective effects of acute normovolemic hemodilution during cardiac surgery. The aim of our study is to show that an increase in endogenous erythropoietin (EPO) might explain the cardioprotective effects of acute normovolemic hemodilution against ischemia-reperfusion phenomena.

Read the detailed description

The major physiologic function of EPO is thought to be the induction of erythropoiesis. However, a growing body of evidence indicates that EPO has tissue-protective effects and prevents tissue damage during ischemia. In an ex vivo proof-of-concept, protective effects of EPO have been shown in human myocardium.

Several studies have demonstrated that acute normovolemic hemodilution before aortic cross clamping decreases perioperative myocardial damage. We hypothesized that the onset of acute anemia increases the endogenous EPO concentration, which explains the cardioprotective effects of acute normovolemic hemodilution.

Questions about this trial

What is this clinical trial studying?

A study testing acute normovolemic hemodilution in people with Cardiac Surgery, run by Cliniques universitaires Saint-Luc- Université Catholique de Louvain at 1 site in Belgium.

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 8 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 3 Mar 2011. 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 Belgium. 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?

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?

Decrease in Troponin -I values (time frame: 4 h). 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 NCT00854217, which also lists 2 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 3 Mar 2011.
