Atherosclerotic plaque characteristics can indicate stroke risk. Identifying vulnerable plaques may guide targeted treatments beyond antiplatelet therapy to prevent future ischaemic events.

Area of Science:

  • Neurology
  • Cardiovascular Medicine
  • Vascular Biology

Background:

  • Ischaemic strokes and transient ischaemic attacks often result from cerebral embolism due to atherosclerotic plaques in arteries.
  • Distinguishing between symptomatic and silent atherosclerotic lesions based solely on plaque structure remains a challenge.
  • Advances in ultrasound imaging have improved understanding of plaque progression and regression.

Purpose of the Study:

  • To review characteristics of vulnerable atherosclerotic plaques.
  • To discuss strategies for improving plaque stability and preventing ischaemic events.

Main Methods:

  • Review of recent biochemical and imaging studies.
  • Analysis of plaque characteristics associated with vulnerability.

  • Evaluation of therapeutic approaches targeting plaque pathophysiology.

    • Main Results:

    • Vulnerable plaque indicators include outward remodelling, intra-plaque haemorrhage, inflammation, severe flow disturbances, cap thinning/ulceration, and abnormal motion.
    • Management of cardiovascular risk factors can improve plaque stability.
    • Targeted biological or pharmacological agents may address plaque pathophysiology.

    Conclusions:

    • Vulnerable plaques pose a risk for unpredictable ischaemic events.
    • Specific preventive treatments, beyond antiplatelet therapy, can be employed for patients with unstable plaques.
    • Understanding plaque characteristics is crucial for personalized stroke prevention strategies.
