Objective:

To develop a simplified, resource-conscious ex vivo rat heart perfusion model capable of inducing key features of myocardial ischemia-reperfusion injury (IRI) as a proof-of-concept.

Key Findings:
  • The IRI group showed a 4.7-fold reduction in coronary flow during early reperfusion, indicating acute vascular dysfunction.
  • Significant infarct development was observed in the IRI group compared to controls, correlating with functional impairment.
  • Histopathological analysis confirmed cardiomyocyte degeneration and inflammatory cell infiltration, highlighting the model's effectiveness.
Interpretation:

The model effectively reproduces fundamental features of myocardial IRI, demonstrating its potential as a proof-of-concept platform for research in resource-limited settings.

Limitations:
  • The model is not a fully validated replacement for conventional Langendorff systems.
  • Variability in procedural execution may affect reproducibility and the reliability of results.
Conclusion:

This study presents a cost-effective ex vivo model for myocardial IRI that enhances accessibility for research in limited-resource environments and has potential applications in broader research contexts.
