Pathophysiology of atherosclerosis: the role of inflammation

Area of Science:

• Cardiovascular Medicine
• Vascular Biology
• Pathophysiology

Background:

• Atherosclerosis is a chronic arterial disease characterized by endothelial dysfunction, inflammation, and intimal buildup of lipids, cholesterol, calcium, and debris.
• Risk factors contribute to atherosclerosis by reducing nitric oxide (NO) bioavailability in the vascular endothelium.
• Clinical manifestations include coronary heart disease, stroke, and peripheral vascular disease, necessitating effective diagnostic and therapeutic strategies.

Purpose of the Study:

• To summarize the key aspects of atherosclerosis, including its pathophysiology, diagnostic methods, and therapeutic interventions.
• To highlight the importance of assessing endothelial function in the diagnosis and management of atherosclerosis.
• To review drug categories effective in ameliorating the inflammatory state associated with atherosclerosis.

Main Methods:

• Review of established knowledge on atherosclerosis pathophysiology and risk factors.
• Identification and discussion of diagnostic modalities, including biochemical markers and imaging techniques for endothelial function.
• Summary of pharmacological treatments targeting the inflammatory aspects of atherosclerosis.

Main Results:

• Atherosclerosis is driven by endothelial dysfunction and inflammation, exacerbated by factors reducing NO bioavailability.
• Diagnostic approaches involve biochemical markers and imaging to assess endothelial function.
• Key drug classes for managing atherosclerosis include ACE inhibitors/ARBs, statins, and antioxidants.

Conclusions:

• Effective management of atherosclerosis requires understanding its complex pathophysiology and risk factors.
• Accurate diagnosis through biochemical markers and endothelial function assessment is critical.
• Pharmacological interventions targeting inflammation and lipid profiles are essential for improving patient outcomes in atherosclerosis.
