Insights

Interleukin-18 (IL-18) and placental growth factor (PLGF) are key biomarkers for identifying vulnerable plaques in patients with non-ST-segment elevated acute coronary syndrome (ACS). These factors can help predict plaque vulnerability and aid in diagnosis.

Area of Science:

  • Cardiovascular Medicine
  • Biomarkers
  • Vascular Biology

Background:

  • Vasoactive factors are linked to vulnerable plaque and acute coronary syndrome (ACS).
  • Understanding these factors is crucial for managing non-ST-segment elevated ACS.
  • Plaque morphology assessment is vital in ACS patient stratification.

Purpose of the Study:

  • To investigate the relationship between specific vasoactive factors and plaque morphology.
  • To determine the predictive value of serum vasoactive factors in non-ST-segment elevated ACS.
  • To assess biomarkers for vulnerable plaque identification.

Main Methods:

  • 124 patients with non-ST-segment elevated ACS underwent coronary angiography and intravascular ultrasound.
  • Serum levels of soluble vascular endothelial growth factor receptor-1 (sFlt-1), placental growth factor (PLGF), and interleukin-18 (IL-18) were measured.
  • Vasoactive factor levels were compared between vulnerable and stable plaque groups, and between unstable angina pectoris (UAP) and non-ST-segment elevation acute myocardial infarction (NSTE-AMI) groups.

Main Results:

  • sFlt-1 and PLGF levels were significantly higher in the vulnerable plaque group compared to the stable plaque group.
  • IL-18 levels showed a positive correlation with plaque morphology.
  • PLGF was identified as an independent risk factor for vulnerable plaque (OR=2.115, P=0.018) and a significant diagnostic factor (AUC=0.799, sensitivity 86%, specificity 63%).

Conclusions:

  • Both IL-18 and PLGF serve as valuable biomarkers for vulnerable plaques.
  • These factors are helpful in predicting vulnerable plaque development in ACS patients.
  • PLGF demonstrates significant diagnostic utility for vulnerable plaque identification.

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 III: Diagnostic Studies

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...

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...

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 I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

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...
