About this study

The objective of this study is to verify the relationship between coronary plaque regression and cardiovascular prevention in long term follow up of the Japan Assessment of Pitavastatin and Atorvastatin in Acute Coronary Syndrome (JAPAN-ACS) study [NCT00242944]. In addition, the effect of serum lipid levels or different type of statins on cardiovascular prevention will also be examined.

Read the detailed description

Several previous multicenter studies using intravascular ultrasound (IVUS) imaging have revealed that statins attenuate the progression of atherosclerosis or even provide regression of plaque volume. Indeed, the Japan Assessment of Pitavastatin and Atorvastatin in Acute Coronary Syndrome (JAPAN-ACS) trial [NCT00242944] has revealed that early aggressive statin therapy in patients with acute coronary syndrome (ACS) significantly reduces the plaque volume of non-culprit coronary lesions On the other hands, a direct relationship between atheroma progression and regression on IVUS and clinical events has not been clearly defined. To verify that relationship, long term follow up of the JAPAN-ACS study will be performed. Clinical outcome of patients with regressed plaque and progressed plaque will be compared. In addition, the objectives of this study are to evaluate the effect of serum lipid levels or different type of statins on cardiovascular prevention.

Questions about this trial

What is this clinical trial studying?

An observational study of Statin and Coronary Plaque, run by Kyoto University at 2 sites in Japan.

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 7 inclusion and 12 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 24 Apr 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Japan. 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?

Composite endpoint (time frame: 4-year). 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 NCT01223586, which also lists 1 linked publication.

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 24 Apr 2012.
