About this study
Official title: Role of Catheter Administered Intracoronary Epinephrine in Prevention of No-Reflow in STEMI Patients Undergoing Primary Percutaneous Coronary Intervention
The aim of this work is to study the role of intracoronary adrenaline administration as a preventive tool for no reflow in patients undergoing primary PCI.
The main question it aims to answer is:

Do prohylcatic intrcoronary adrenaline reduce the incidence of no reflow without increaing risk of arrhythmia in primary PCI?
The procedure will be performed by expert operators. All patients will receive the guidelines-directed recommendations of intervention of STEMI patients.
Study group wil receive Intracoronary 10 mcg adrenaline via the guiding catheter after restoration of epicardial coronary flow of the culprit vessel and achievement of TIMI I flow either after wiring and/or passage of a deflated balloon and/or PTCA with a small balloon, and/or use of thrombus aspiration and before stenting.
All steps in the Cath-lab will be described in detail:
The primary end points will be improvement in coronary flow, as assessed by TIMI (Thrombolysis in Myocardial Infarction) flow, and myocardial blush.
Secondary end points will be in-hospital mortality and major adverse cardiac events.

What is being measured
The primary outcome is the main question the study is designed to answer.
No-relow
The primary end points will be improvement in coronary flow, as assessed by TIMI (Thrombolysis in Myocardial Infarction) flow
Thrombolysis in Myocardial Infarction risk score (TIMI) flow grading system as following:
- TIMI 0 = No ante-grade flow beyond the point of occlusion.
- TIMI 1 = Faint ante-grade flow beyond the point of occlusion with incomplete filling of the distal vascular bed.
- TIMI 2 = Delayed or sluggish ante-grade flow with complete filling of the distal vascular beds.
- TIMI 3 = Normal flow with complete filling of the distal vascular bed
Coronary no-reflow (CNR) is diagnosed immediately after PCI when post-procedural angiographic TIMI flow is < 3
Measured: 1 year up to 2 years
No-relow
The primary end points will be improvement in coronary flow, as assessed by myocardial blush grade.
Myocardial blush grade (MBG) is defined as:
- MBG 0 = No myocardial blush or contrast density.
- MBG 1 = Minimal myocardial blush or contrast density.
- MBG 2 = Moderate myocardial blush or contrast density but less than that obtained during angiography of a contralateral or ipsi-lateral non-infarct-related coronary artery.
- MBG 3 = Normal myocardial blush or contrast density, comparable with that obtained during angiography of a contralateral or ipsilateral non-infarct-related coronary artery
Coronary no-reflow (CNR) is diagnosed immediately after PCI when post-procedural angiographic MBG is 0 or 1
Measured: 1 year up to 2 years
Secondary outcomes (1)
MACE
Secondary end points will be major adverse cardiac events.
Measured: 1 year up to 2 years

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Adrenaline in people with ST Segment Elevation Myocardial Infarction (STEMI) and No Reflow Phenomenon, run by Ain Shams University at 1 site in Egypt.
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 10 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: looking for participants now, as of the sponsor's last update on 11 Mar 2025. 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 Egypt. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Mostafa Abdallah Khalifa, Master cardiology (+201012988025, mostafaabdallahkhalifa@med.asu.edu.eg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
No-relow (time frame: 1 year up to 2 years). 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?
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 11 Mar 2025; AzTrials last refreshed its copy on 8 Nov 2026.
