Atherosclerotic plaque rupture can cause coronary microembolization, leading to arrhythmias and heart dysfunction. This review covers evidence and prevention strategies for this condition.

Area of Science:

  • Cardiovascular Medicine
  • Pathology
  • Interventional Cardiology

Background:

  • Atherosclerotic plaque rupture is central to acute coronary syndromes and interventions.
  • Plaque rupture can lead to microembolization into the coronary microcirculation, not always complete occlusion.
  • Coronary microembolization is implicated in sudden death and milder forms of coronary artery disease.

Purpose of the Study:

  • To summarize morphologic, experimental, and clinical evidence of coronary microembolization.
  • To highlight the clinical features and pathophysiology of coronary microembolization.
  • To discuss prevention strategies for coronary microembolization.

Main Methods:

  • Review of morphologic evidence in deceased patients with coronary artery disease.

Related Experiment Videos

  • Analysis of experimental pathophysiology in animal models of acute coronary syndromes and heart failure.
  • Synthesis of clinical evidence, including key features and prevention methods.

    • Main Results:

    • Morphologic evidence supports coronary microembolization in patients with coronary artery disease.
    • Animal models elucidate the pathophysiology of microembolization in acute coronary syndromes and heart failure.
    • Clinical features include arrhythmias, contractile dysfunction, infarctlets, and reduced coronary reserve.

    Conclusions:

    • Coronary microembolization is a significant consequence of atherosclerotic plaque rupture.
    • Understanding its pathophysiology and clinical manifestations is crucial.
    • Mechanical protection devices and glycoprotein IIb/IIIa antagonism show promise for prevention.
