Summary
Atherosclerosis regression and stabilization are significantly improved with treatment, reducing clinical events. Non-invasive imaging like carotid intima-media thickness (IMT) offers a reliable, cost-effective method for assessing risk and augmenting studies.
Area of Science:
- Cardiovascular Medicine
- Medical Imaging
- Preventive Cardiology
Background:
- Atherosclerosis progression is a major cause of cardiovascular events.
- Angiography provides lumen visualization but limited arterial wall information.
- Non-invasive imaging offers potential for better assessment of atherosclerosis.
Purpose of the Study:
- To review evidence on atherosclerosis reversibility and the role of non-invasive imaging.
- To evaluate the efficacy of treatments in altering atherosclerotic lesion progression.
- To explore non-invasive methods for assessing atherosclerosis and predicting clinical outcomes.
Main Methods:
- Meta-analysis of coronary angiographic trials.
- Review of studies on lipid-lowering therapies and adjunctive treatments.
- Evaluation of non-invasive B-mode ultrasonographic imaging of carotid intima-media thickness (IMT).
Main Results:
- Treatments increase lesion regression/stabilization 1.5-2x and halve progression compared to placebo.
- Coronary events are significantly reduced with treatment.
- Carotid IMT is a reliable measure of early atherosclerosis, associated with coronary artery disease, and a potential surrogate endpoint.
Conclusions:
- Atherosclerosis can be reversed or stabilized with effective therapies.
- Lipid management and potential adjunctive therapies (antioxidants, HRT) are crucial.
- Non-invasive carotid IMT measurement is a valuable tool for risk assessment and augmenting clinical trial endpoints.
