Summary
Identifying vulnerable atherosclerotic plaques, which cause heart attacks and strokes, is difficult. New imaging techniques are needed to detect these unstable lesions for timely treatment.
Area of Science:
- Cardiovascular Medicine
- Medical Imaging
- Atherosclerosis Research
Background:
- Rupture of vulnerable atherosclerotic plaques is a major cause of myocardial infarction and stroke.
- Current methods for timely identification of these high-risk plaques remain a clinical challenge.
- Understanding the cellular and molecular characteristics of vulnerable plaques is crucial for risk stratification.
Purpose of the Study:
- To review current and emerging imaging techniques for identifying vulnerable atherosclerotic plaques.
- To assess the capabilities of these techniques in detecting lesions prone to rupture.
- To highlight the need for advanced imaging to guide therapeutic interventions.
Main Methods:
- Review of existing clinical imaging modalities.
- Evaluation of techniques under investigation in clinical trials.
- Analysis of imaging's ability to characterize plaque components (cellular, biochemical, molecular).
Main Results:
- Certain imaging techniques show promise in identifying vulnerable plaque characteristics.
- Ongoing clinical trials are exploring novel approaches for plaque imaging.
- A gap exists between current capabilities and the ideal for identifying rupture-prone lesions.
Conclusions:
- Advanced imaging techniques are essential for the early detection of vulnerable atherosclerotic plaques.
- Improved imaging can facilitate targeted therapies to prevent cardiovascular events.
- Further development and validation of imaging modalities are required to address clinical needs.
