Area of Science:

  • Cardiovascular Medicine
  • Pathology
  • Vascular Biology

Background:

  • Significant advancements in understanding atherosclerosis pathogenesis and its cardiovascular impact over the past decade.
  • Unstable atherosclerotic plaques, responsible for most acute coronary events, are characterized by specific features like lipid-rich cores and thin fibrous caps.
  • Lipid modification strategies show promise in cardiovascular risk reduction.

Purpose of the Study:

  • To review the current understanding of atherosclerosis pathogenesis and the characteristics of unstable plaques.
  • To discuss the vascular effects of lipid modification and its role in clinical benefits.
  • To explore the potential of new imaging technologies in identifying and managing at-risk plaques.

Main Methods:

  • Literature review of recent research on atherosclerosis pathogenesis.
  • Analysis of studies on unstable plaque characteristics.
  • Examination of data on lipid modification therapies and cardiovascular prevention trials.
  • Review of emerging imaging technologies for plaque visualization.

Main Results:

  • Detailed definition of unstable plaque morphology: mild-to-moderate stenosis, lipid-rich pool, few smooth muscle cells, friable fibrous cap, and macrophage infiltration.
  • Lipid modification demonstrates vascular effects contributing to benefits observed in prevention trials.
  • Advancements in imaging technologies offer potential for improved visualization of at-risk plaques.

Conclusions:

  • A sophisticated understanding of atherosclerosis pathogenesis has been achieved.
  • Lipid modification is a crucial strategy for cardiovascular risk reduction.
  • New imaging technologies hold promise for better management of unstable atherosclerotic plaques.
