Endothelial Cell Dysfunction and the Pathobiology of Atherosclerosis

Area of Science:

• Cardiovascular Medicine
• Vascular Biology
• Pathobiology

Background:

• Endothelial cell dysfunction is a key factor in the development of atherosclerotic cardiovascular disease.
• It involves alterations in hemostasis, thrombosis, vascular tone, redox balance, and inflammation.
• These changes occur in lesion-prone areas of the arterial vasculature.

Purpose of the Study:

• To review the concept of endothelial cell dysfunction in atherosclerotic cardiovascular disease.
• To highlight recent cellular and molecular insights into its role in lesion initiation and progression.
• To explore its connection to clinical risk factors and discuss assessment, detection, and treatment strategies.

Main Methods:

• Literature review focusing on cellular and molecular mechanisms.
• Analysis of the relationship between endothelial dysfunction and clinical risk factors.
• Evaluation of current clinical assessment methods.
• Identification of novel detection and treatment approaches.

Main Results:

• Endothelial dysfunction encompasses multiple nonadaptive functional alterations.
• It plays a pivotal role in both the initiation and progression of atherosclerotic lesions.
• The review connects dysfunction to established and emerging clinical risk factors.

Conclusions:

• Endothelial cell dysfunction is central to atherosclerotic cardiovascular disease pathobiology.
• Further research into its mechanisms is crucial for developing targeted therapies.
• Improved clinical assessment and early detection strategies are needed.
