Interventional strategies in early atherosclerosis.

Area of Science:

• Cardiovascular Medicine
• Diagnostic Imaging
• Preventive Cardiology

Background:

• Atherosclerosis often presents late with acute cardiovascular events.
• Early detection and intervention are crucial for managing cardiovascular risk.
• Non-invasive imaging aids in identifying subclinical atherosclerosis.

Purpose of the Study:

• To highlight the importance of detecting atherosclerosis in its preclinical phase.
• To evaluate the efficacy of various therapeutic strategies in slowing atherosclerosis progression.
• To determine the optimal approach for managing asymptomatic individuals at cardiovascular risk.

Main Methods:

• Utilized non-invasive diagnostic procedures like carotid intima-media thickness (CIMT) ultrasonography, electron beam computed tomography (EBCT), and magnetic resonance angiography (MRA).
• Reviewed prospective trials on multifactorial non-pharmacological interventions (diet, exercise, smoking cessation).
• Assessed the impact of pharmacological interventions targeting LDL, blood pressure, and platelet aggregation.

Main Results:

• Non-invasive imaging techniques effectively identify early-stage atherosclerosis and monitor disease progression.
• Lifestyle modifications demonstrated a favorable effect on slowing atherosclerosis progression in asymptomatic individuals.
• Targeting LDL, blood pressure, and platelet aggregation showed effectiveness in high-risk subjects.

Conclusions:

• Lifestyle modification is a cost-effective first-line strategy for preclinical atherosclerosis.
• Pharmacological interventions are recommended as a second step or adjunct therapy for high-risk individuals.
• Emerging risk factors like oxidative stress require further investigation for their role in atherosclerosis treatment.
