Coronary Microembolization | Circulation - AHA/ASA Journals
Nov 3, 2009 · Coronary microembolization from the erosion or rupture of a vulnerable atherosclerotic plaque occurs spontaneously in acute coronary syndromes and iatrogenically during percutaneous coronary interv...
A fresh look at coronary microembolization - Nature
Nov 16, 2021 · Coronary microembolization results from spontaneous or interventional erosion or rupture of an epicardial coronary atherosclerotic plaque. Atherothrombotic plaque debris causes...
Coronary microembolization - Journal of the American College …
A series of recent studies identified coronary microembolization as a potential cause of regional myocardial contractile dysfunction in the absence of an atherosclerotic obstruction of an epicardial coronary artery that could account for such dysfunction.
Coronary microembolization - ScienceDirect
Jul 1, 2004 · This review summarizes the available morphological evidence for coronary microembolization in patients who died from coronary artery disease, most notably from sudden death. Then the experimental pathophysiology of coronary microembolization in animal models of acute coronary syndromes is detailed.
A fresh look at coronary microembolization - PubMed
We propose that coronary microembolization is a decisive link between plaque erosion at the culprit lesion and the manifestation of non-ST-segment elevation myocardial infarction. In this Review, we characterize the features and mechanisms of coronary microembolization and discuss the clinical trials of drugs and devices for prevention and ...
Coronary microembolization and microvascular dysfunction
May 1, 2018 · Coronary microembolization involves physical obstruction, vasoconstriction and inflammation in the coronary microcirculation. Release of partial debris and soluble substances from the culprit lesion can sensitize the coronary microcirculation and contribute to angina in the absence of epicardial obstruction.
A fresh look at coronary microembolization - PMC
Coronary microembolization occurs spontaneously and as a result of cardiac, mostly coronary, interventions. Spontaneous coronary microembolization, typically symptomatic as an acute coronary syndrome, can be ascertained only at autopsy after sudden cardiac death 3–6,97.
Coronary microembolization - PubMed
This review summarizes the present experimental pathophysiology of coronary microembolization in animal models of acute coronary syndromes and highlights the main consequences of coronary microembolization--reduced coronary reserve, microinfarction, inflammation and oxidative modification of contractile proteins, contractile dysfunction and ...

Coronary Flow Effects of Arterial Spasm or Microembolization
Mar 6, 2023 · Microembolization needs to be a consideration in the pathophysiology of coronary artery disease (CAD), and it represents a key event during coronary intervention, especially in the ACS setting. Spontaneous and procedural micro-embolization can both lead to myocardial injury, but the main clinical implications are in ACS patients.
