Trial summary

Reocclusion of the infarct artery is observed in about 30% of patients within three months after successful thrombolysis for acute myocardial infarction (MI). Reocclusion is associated with an increased risk of death, reinfarction and the need for revascularization. Read more about this study

About this study

Official title: A Multicenter Randomized Trial in the Prevention of Reocclusion Following Successful Thrombolysis for Suspected Acute Myocardial Infarction: An Invasive Versus a Conservative Strategy

Reocclusion of the infarct artery is observed in about 30% of patients within three months after successful thrombolysis for acute myocardial infarction (MI). Reocclusion is associated with an increased risk of death, reinfarction and the need for revascularization. Even in the absence of clinical reinfarction, reocclusion results in impaired left ventricular (LV) recovery, leaving patients at increased risk of developing heart failure in the long-term. Prevention of reocclusion is therefore warranted. In previous trials, severity of the infarct related stenosis was the only independent predictor of reocclusion. With a lack of clinical predictors of reocclusion, many cardiologists therefore empirically favor routine revascularization after successful thrombolysis.

The APRICOT-3 will be the first randomized trial in the current era of improved angioplasty techniques to study the question of whether a routine invasive strategy after successful thrombolysis can reduce the incidence of reocclusion and subsequently improve clinical outcome and LV-function. After successful thrombolysis, patients will be randomized to either a routine invasive strategy or an ischemia-guided strategy. The investigators expect to demonstrate a lower reocclusion rate at the 6-month follow-up angiography (primary endpoint) and fewer associated events (death, reinfarction, revascularization, admissions for heart failure) in the routine invasive arm. In search of non-invasive parameters predictive of reocclusion, laboratory analysis of several coagulation and inflammatory markers will be performed. Finally, pooled analysis of all 3 APRICOT trials will focus on the identification of clinical predictors of reocclusion that can easily be obtained by history and physical examination.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Percutaneous coronary intervention (PCI) in people with Myocardial Infarction, run by Heartcenter, University Medical Center St. Radboud at 1 site in Netherlands.

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 6 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 30 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 1 site in Netherlands. 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?

Yes. Results are posted in the registry (first posted 19 Apr 2012). 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?

6-month Reocclusion (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 30 Apr 2012.
