Identifying vulnerable atherosclerotic plaques is crucial for preventing acute coronary events. Molecular imaging techniques are advancing to assess plaque biology in vivo, aiming for better cardiovascular risk assessment.

Area of Science:

  • Cardiovascular Medicine
  • Molecular Imaging
  • Atherosclerosis Research

Background:

  • Acute coronary events often arise from rupture of atherosclerotic plaques with minimal luminal narrowing.
  • Vulnerable plaques possess characteristic but variable morphologic and biologic features preceding rupture.

Purpose of the Study:

  • To explore molecular imaging techniques for identifying vulnerable atherosclerotic plaques.
  • To advance in vivo assessment of vascular biology for improved cardiovascular risk stratification.

Main Methods:

  • Development of molecular-targeted radiolabeled probes to visualize specific plaque characteristics.
  • Investigation of approaches targeting plaque inflammation, apoptosis, smooth muscle cell proliferation, extracellular matrix activation, and platelet binding.

Main Results:

  • Molecular imaging of atherosclerosis is an evolving field with various targeting strategies introduced.
  • Challenges remain in translating animal models, clinical imaging methodology, and patient selection.

Conclusions:

  • Despite ongoing challenges, molecular imaging is progressing towards in vivo assessment of vascular biology.
  • The ultimate goal is to enhance clinical risk assessment for cardiovascular diseases through advanced imaging.
