Atherothrombosis and plaque heterology: different location or a unique disease?

Area of Science:

• Cardiovascular Science
• Vascular Biology
• Thrombosis Research

Background:

• Unstable plaques cause atherothrombosis, a primary driver of ischemic stroke, myocardial infarction, and peripheral arterial disease.
• Patients with symptomatic thrombosis in one vascular area face elevated risks in other vascular beds.
• Distinct pathophysiological mechanisms in carotid, coronary, and peripheral arteries may necessitate tailored treatment protocols.

Purpose of the Study:

• To review known risk factors for atherothrombosis.
• To compare the developmental characteristics of coronary and carotid artery plaque.
• To associate plaque development with ischemic end-point events.

Main Methods:

• Literature review of risk factors and plaque development.
• Comparative analysis of coronary and carotid artery plaque pathophysiology.
• Examination of genetic contributions and cellular signaling in thrombosis-prone regions.

Main Results:

• Significant differences exist in the pathophysiology of coronary versus carotid artery plaque development.
• Variations are observed in genetic influences, gene/protein expression, and cellular signaling pathways.
• These differences may correlate with distinct anatomopathological features and rupture risks.

Conclusions:

• Understanding the distinct features of plaque development in different arterial beds is crucial.
• Differences in carotid and coronary plaque development may explain variations in clinical presentation and rupture susceptibility.
• Tailored therapeutic strategies may be required to effectively manage atherothrombosis across diverse vascular locations.
