Administering adrenaline in STEMI patients during PCI to prevent no reflow

Role of Catheter Administered Intracoronary Epinephrine in Prevention of No-Reflow in STEMI Patients Undergoing Primary Percutaneous Coronary Intervention

PHASE3 · Ain Shams University · NCT06847568

What this trial studies

This clinical trial investigates the administration of intracoronary adrenaline in patients with ST Segment Elevation Myocardial Infarction (STEMI) during primary percutaneous coronary intervention (PCI). The study aims to determine if prophylactic use of adrenaline can reduce the incidence of no reflow without increasing the risk of arrhythmias. Patients will receive adrenaline after restoring coronary flow and before stenting, with expert operators performing the procedure. The primary endpoint is the improvement in coronary flow assessed by TIMI flow grading.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older presenting with acute coronary syndrome and diagnosed with STEMI within 12 hours of symptom onset.

Not a fit: Patients who may not benefit include those under 18, pregnant women, and individuals with contraindications to epinephrine or other serious cardiac conditions.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the occurrence of no reflow in STEMI patients, improving their outcomes post-PCI.

How similar studies have performed: While the use of adrenaline in this context is being explored, similar studies have shown promise in improving coronary flow, making this approach potentially beneficial.
