About this study

The goal of this study is to evaluate the possible preoperative predictive value of altered heart rate variability (HRV) and baroreflex sensitivity in different sleep stages for postoperative adverse cardiac events (i.e. arrhythmia or myocardial ischemia needing hospitalization or medication, myocardial ischemia assessed by enzyme release, myocardial infarction, sudden cardiac death, stroke) in arteriosclerosis obliterans patients.

Questions about this trial

What is this clinical trial studying?

An observational study of Arteriosclerosis Obliterans, run by GE Healthcare at 1 site in Finland.

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 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

What are the possible benefits and risks?

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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00712946, 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 28 Apr 2011.
