About this study

Official title: The Use of Enoxaparin Compared to Unfractionated Heparin for Short Term Antithrombotic Therapy in Atrial Fibrillation Patients Undergoing TEE Guided Cardioversion: Assessment of Cardioversion Using Transesophageal Echocardiography (ACUTE) II Randomized Multicenter Study

SPECIFIC AIM: To test the safety and feasibility of using low molecular weight heparin (LMWH, enoxaparin sodium; Lovenox, Sanofi-Aventis) in lieu of unfractionated heparin (UFH) as antithrombotic therapy for patients in atrial fibrillation undergoing transesophageal echocardiography (TEE) guided chemical or electrical cardioversion to sinus rhythm.

HYPOTHESIS: Early cardioversion from atrial fibrillation can be safely performed using a short-term anticoagulation strategy of low molecular weight heparin (Lovenox, Sanofi-Aventis) compared to unfractionated heparin, accompanied by a TEE examination prior to cardioversion. The use of LMWH with TEE will result in a safe, cost-effective, and possible efficacious approach to cardioversion of atrial fibrillation compared to UFH with TEE.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Enoxaparin in people with Atrial Fibrillation, run by The Cleveland Clinic 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 4 inclusion and 27 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 31 Jan 2007. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

ischemic stroke. The study lists 7 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 NCT00289042, which also lists 4 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 31 Jan 2007.
