Narrative Review: Reperfusion Strategies for ST-Segment Elevation Myocardial Infarction
Key result
A systematic framework incorporating duration of symptoms and anticipated transport delays guides the selection of primary PCI versus thrombolytic therapy for STEMI patients.
Why the study?
What is the optimal reperfusion strategy (primary PCI vs thrombolytic therapy) for patients with ST-segment elevation myocardial infarction presenting to non-PCI capable hospitals?

Implication
May aid reperfusion decisions at non-PCI hospitals; leaves open prospective validation of the symptom- and delay-based algorithm.
Key Points
- To synthesize clinical evidence and provide a structured framework for choosing between primary percutaneous coronary intervention and thrombolytic therapy in patients with acute myocardial infarction.
- Narrative review evaluating clinical trial outcomes and national guidelines regarding primary percutaneous coronary intervention versus fibrinolysis.
- Evaluation of treatment timelines factoring in symptom onset duration (fixed ischemia) and transfer delays to catheterization-capable facilities (incurred ischemia).
- Primary percutaneous coronary intervention is the superior reperfusion modality when available immediately at capable medical centers.
- Thrombolytic therapy serves as a critical alternative when transfer times to a catheterization laboratory significantly delay mechanical intervention.
- A systematic algorithm incorporating both fixed and transport-related ischemia times enables clinicians to rapidly determine whether to transfer or administer immediate lytic therapy.

This review provides a practical framework for clinicians to choose between primary PCI and thrombolytic therapy for STEMI patients based on ischemia time and transport delays.
Cite This Study
Ting et al. (2006) conducted a review in ST-Segment Elevation Myocardial Infarction. Reperfusion strategies (primary PCI and thrombolytic therapy) was evaluated. A systematic framework incorporating duration of symptoms and anticipated transport delays guides the selection of primary PCI versus thrombolytic therapy for STEMI patients.
