Acute coronary syndromes as auto-inflammatory disorders

Area of Science:

• Cardiovascular Medicine
• Immunology
• Pathophysiology

Background:

• Acute coronary syndromes (ACS) are characterized by persistent inflammation from onset to healing.
• Early reperfusion therapies (thrombolysis, percutaneous coronary intervention) offer clinical benefits but can be offset by ischemia/reperfusion injury.
• Inflammation, while potentially protective, is intrinsically linked to detrimental ACS conditions.

Purpose of the Study:

• To comprehensively review the pathogenesis of ACS, focusing on the role of vascular inflammation.
• To update understanding of the complex molecular, cellular, and organ-level mechanisms driving inflammation in ACS.
• To explore the hexagonal vascular inflammatory network's contribution to ACS pathogenesis.

Main Methods:

• Literature review and synthesis of current research on ACS pathogenesis.
• Analysis of molecular and cellular inflammatory pathways involved in ACS.
• Examination of the components and interactions within the vascular inflammatory network.

Main Results:

• Inflammation is a central, continuous process throughout ACS, from initial event to healing.
• Ischemia/reperfusion injury, despite therapeutic interventions, contributes to adverse outcomes.
• A complex 'hexagonal vascular inflammatory network' involving leukocytes, endothelial cells, smooth muscle cells, platelets, ROS, and cholesterol perpetuates ACS pathology.

Conclusions:

• Vascular inflammation is a critical factor in the pathogenesis of acute coronary syndromes.
• Targeting the vascular inflammatory network may offer novel therapeutic strategies for ACS prevention and treatment.
• Further research into the cross-talk mechanisms within the inflammatory network is essential for clinical advancement.
