Cytokines and coronary artery disease: the state of the art

Area of Science:

• Cardiovascular Medicine
• Immunology
• Biochemistry

Background:

• Coronary atherosclerosis is intrinsically linked to inflammation and the delicate balance of cytokines.
• Cytokines, signaling molecules involved in immune responses, are increasingly recognized for their role in cardiovascular pathophysiology.
• Understanding these inflammatory mediators is crucial for advancing the management of coronary artery disease (CAD).

Purpose of the Study:

• To elucidate the role of cytokines in the pathophysiology of coronary artery disease.
• To explore the potential of cytokines in the clinical management of CAD.
• To review and synthesize existing literature on cytokines and CAD from 1987 to 2007.

Main Methods:

• Systematic literature review of pertinent articles.
• Databases searched include Medline, Scopus, and EBSCO Host.
• Analysis focused on studies published between 1987 and 2007.

Main Results:

• Both proinflammatory and anti-inflammatory cytokines are present in human atherosclerotic plaques.
• The balance between these cytokine groups correlates with plaque inflammation intensity and rupture risk.
• Proinflammatory biomarkers provide prognostic information beyond traditional CAD risk factors.
• Inflammatory responses post-coronary revascularization contribute to vascular lesion formation and restenosis.

Conclusions:

• Cytokine balance is a critical factor in coronary atherosclerosis progression and plaque stability.
• Proinflammatory biomarkers offer valuable prognostic insights in CAD.
• Further research is needed to fully explore the clinical utility of cytokines in CAD management.
• Targeting cytokine pathways may represent a future therapeutic strategy for CAD.
