Investigating late reperfusion therapy for heart attack patients

Late Reperfusion With Percutaneous Coronary Intervention in Patients With ST-segment Elevation Myocardial Infarction

Not applicable Interventional Rigshospitalet, Denmark · NCT02445885

This study is testing if heart attack patients who arrive at the hospital more than 12 hours after their symptoms start can benefit from a certain heart procedure to improve their recovery.

What this trial studies

This study examines whether patients with ST-segment elevation myocardial infarction (STEMI) who present more than 12 hours after symptom onset can benefit from acute percutaneous coronary intervention (PCI) compared to delayed PCI. The research focuses on patients who are clinically stable and have experienced symptoms for 12 to 36 hours. By utilizing magnetic resonance imaging to evaluate the final salvage index, the study aims to determine if extending the time limit for acute PCI could improve outcomes for late presenters. The findings could potentially redefine treatment protocols for this patient population.

Who should consider this trial

Good fit: Ideal candidates are patients over 18 years old with STEMI symptoms lasting between 12 and 36 hours who are clinically stable.

Not a fit: Patients who are clinically unstable or have conditions requiring immediate invasive strategies will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide evidence to support the use of acute PCI in late presenters, potentially improving their cardiac outcomes.

How similar studies have performed: While the approach of investigating late PCI is less common, similar studies have shown varying results, indicating that this area remains underexplored.
