Insights

A non-stent strategy for acute coronary syndrome from plaque erosion is viable. Older age, greater stenosis, and higher thrombus burden predict worse outcomes in these patients.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Vascular Biology

Background:

  • The EROSION study established the safety of antithrombotic therapy without stenting for acute coronary syndrome (ACS) due to plaque erosion.
  • Predictors of long-term prognosis in this patient group remain unclear, necessitating further investigation.

Purpose of the Study:

  • To identify predictors of adverse prognosis in patients treated with a non-stent strategy for ACS caused by plaque erosion.
  • To validate these predictors in a larger patient cohort.

Main Methods:

  • A cohort of 252 patients with ACS and plaque erosion, including 55 from the EROSION study, were analyzed.
  • Major adverse cardiovascular events (MACE) were defined as cardiac death, recurrent MI, revascularization, angina rehospitalization, bleeding, or stroke.
  • Multivariate Cox regression identified predictors of MACE at a median follow-up of 2.9 years.

Main Results:

  • Among 232 patients, 21.6% experienced MACE.
  • Patients with MACE were older, with higher baseline percentage area stenosis (72.2% vs. 64.2%) and thrombus burden (24.4% vs. 20.4%).
  • Age (≥60 years), area stenosis (≥63.5%), and thrombus burden (≥18.5%) were independent predictors of MACE.

Conclusions:

  • The non-stent strategy for ACS from plaque erosion shows heterogeneous outcomes.
  • Specific patient characteristics—age ≥60 years, area stenosis ≥63.5%, and thrombus burden ≥18.5%—are associated with a higher risk of MACE.

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...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

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...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
