Insights

Atherosclerotic plaque rupture can cause coronary microembolization, leading to infarctlets and arrhythmias. This review covers evidence and prevention strategies for this condition in acute coronary syndromes.

Area of Science:

  • Cardiology
  • Pathophysiology
  • Medical Research

Background:

  • Atherosclerotic plaque rupture is central to acute coronary syndromes.
  • Plaque rupture can lead to microembolization into the coronary microcirculation, not always complete occlusion.

Purpose of the Study:

  • To review morphological, experimental, and clinical evidence of coronary microembolization.
  • To highlight key clinical features and prevention strategies for coronary microembolization.

Main Methods:

  • Morphological analysis of coronary microembolization in deceased patients.
  • Experimental studies in animal models of acute coronary syndromes and heart failure.
  • Review of clinical evidence and features of coronary microembolization.

Main Results:

  • Morphological evidence supports coronary microembolization in coronary artery disease.
  • Animal models demonstrate the pathophysiology of microembolization.
  • Clinical features include arrhythmias, contractile dysfunction, infarctlets, and reduced coronary reserve.

Conclusions:

  • Coronary microembolization is a significant consequence of plaque rupture.
  • Understanding its features aids in diagnosis and management.
  • Mechanical devices and glycoprotein IIb/IIIa inhibitors show promise for prevention.

Pulmonary Embolism I: Introduction01:29

Pulmonary Embolism I: Introduction

Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
Acute Coronary Syndrome I: Introduction01:30

Acute Coronary Syndrome I: Introduction

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Coronary Artery Disease II: Pathophysiology

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Myocarditis I: Introduction

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
