Introduction: Coronary microvascular disease (MVD) affects millions worldwide, yet its early detection and treatment remain challenging. Researchers from Yale University have developed an innovative mouse model using photochemical reaction (PCR) technology to replicate early-stage MVD conditions. This breakthrough offers new opportunities for understanding the disease and testing potential treatments.

Understanding Coronary Microvascular Disease:

  • MVD is prevalent in patients experiencing unexplained chest pain despite normal coronary angiograms.
  • Studies, including NIH-WISE, reveal that millions of individuals, especially women, suffer from MVD.
  • Endothelial dysfunction, oxidative stress, and microthrombi are key contributors to MVD progression.

A Novel Mouse Model for MVD:

  • Researchers hypothesized that PCR technology could reproduce MVD in mice.
  • The study used rose bengal, a photosensitizer, activated by green light to induce oxidative stress and endothelial injury.
  • Mice subjected to this model demonstrated endothelial dysfunction, arteriolar occlusion, and localized ischemia, closely mirroring human MVD conditions.

Advantages of This Model:

  • Reproducible lesions with controlled size and location.
  • Minimal surgical manipulation, reducing procedural mortality (<6%).
  • Preserved global cardiac function, making it ideal for long-term studies.
  • A potential platform for testing new diagnostic tools and therapies.

Clinical Implications:

  • The model offers insights into endothelial dysfunction and microthrombi formation in MVD.
  • It facilitates the development of molecular imaging tracers for early diagnosis.
  • Provides a reliable system for evaluating anti-fibrinolytic and anti-thrombotic drugs.

Integration of External Medical Sources: The American Heart Association (AHA) highlights the importance of early detection and intervention in microvascular conditions, emphasizing lifestyle modifications and pharmacological therapies to manage endothelial dysfunction and oxidative stress.
