Trial summary

No-reflow is defined as the lack of myocardial perfusion despite opening of the epicardial coronary vessels in the setting of percutaneous coronary intervention (PCI). It has been demonstrated that either impaired flow or the absence of flow is associated with an increased rate of mortality. Read more about this study

About this study

Official title: Efficacy of Intracoronary Adrenaline and Its Comparison With Intracoronary Adenosine in the Treatment of No-Reflow in Normotensive Patients With Acute Coronary Syndrome

No-reflow is defined as the lack of myocardial perfusion despite opening of the epicardial coronary vessels in the setting of percutaneous coronary intervention (PCI). It has been demonstrated that either impaired flow or the absence of flow is associated with an increased rate of mortality. Among available treatment options, intracoronary adenosine is widely used in clinical practice, moreover, adrenaline is a safe alternative for the cases where use of adenosine is limited due to presence of hypotension or bradycardia. Nonetheless, evidence from retrospective and observational studies suggest that intracoronary adrenaline is well tolerated and may exert encouraging effects in prompt recovery of flow in these patients. However, very limited data are available on efficacy of intracoronary (IC) adrenaline in normotensive patients. Therefore, this study is planned to study the hypothesis that; intracoronary adrenaline is safe and has significantly higher efficacy as compared to adenosine for the treatment of no-reflow in normotensive patients with acute coronary syndrome.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Adrenaline and Adenosine in people with Acute Coronary Syndrome and No-Reflow Phenomenon, run by National Institute of Cardiovascular Diseases, Pakistan at 1 site in Pakistan.

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 2 inclusion and 7 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 21 May 2021. 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 Pakistan. 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?

Improvement in Thrombolysis in Myocardial Infarction (TIMI) flow grade (time frame: Immediately after administration of drug). The study lists 2 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 NCT04699110, 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 21 May 2021.
