Insights

Acute coronary syndromes are linked to unstable plaques, not just severe blockages. Inflammation drives instability, making plaque stabilization a new treatment goal, potentially aided by statins.

Area of Science:

  • Cardiology
  • Pathophysiology
  • Pharmacology

Background:

  • Traditional views on acute coronary syndromes (ACS) pathogenesis are evolving.
  • High-risk lesions in ACS are now understood to be characterized by plaque composition rather than solely by angiographic severity.
  • Plaque instability, driven by intra-intimal inflammation, is a key factor in ACS development.

Purpose of the Study:

  • To review recent advancements in understanding ACS pathogenesis.
  • To highlight the shift towards plaque stabilization as a therapeutic target.
  • To discuss the role of statins in modulating inflammatory responses for lesion stabilization.

Main Methods:

  • Literature review of recent studies on ACS pathogenesis.
  • Analysis of findings related to high-risk plaque characteristics (lipid core, fibrous cap).
  • Examination of evidence linking inflammation to plaque instability and therapeutic interventions.

Main Results:

  • High-risk lesions are defined by large lipid cores and thin fibrous caps, irrespective of angiographic severity.
  • Inflammation within the intima is a critical determinant of plaque instability.
  • Statins show potential in stabilizing lesions by modulating the inflammatory cascade.

Conclusions:

  • Plaque stabilization represents a novel therapeutic strategy for managing acute coronary syndromes.
  • Understanding the inflammatory basis of plaque instability is crucial for clinical practice.
  • Statins may offer benefits beyond lipid-lowering by stabilizing vulnerable atherosclerotic plaques.

Overview
Inflammatory Response I: Vascular and Cellular01:30

Inflammatory Response I: Vascular and Cellular

The inflammatory response is the body's defense against infection, injury, or irritation from bacteria, trauma, toxins, or heat. Inflammation helps locate and destroy pathogens and remove damaged tissue elements to heal the body. During this initial phase, fluid, blood products, and nutrients migrate to the injured area, resulting in redness, heat, swelling, ache, and loss of function. Moreover, signs of systemic inflammation include fever, increased WBC count, malaise, anorexia, nausea,...

Inflammatory Response

An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
Acute Inflammation I: Inflammatory Response01:26

Acute Inflammation I: Inflammatory Response

Acute inflammation is a rapid, short-lived physiological response to tissue injury or infection, designed to eliminate harmful agents and initiate repair. This tightly regulated process typically lasts from minutes to several days and is triggered by factors such as microbial invasion, physical trauma, or chemical injury.Recognition and Mediator ReleaseThe inflammatory response begins when resident immune cells—such as mast cells, macrophages, and dendritic cells—detect damage-associated...
Acute Inflammation III: Local and Systemic Effects01:25

Acute Inflammation III: Local and Systemic Effects

Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...
Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
