Local to Systemic Inflammation-From Generation to Prognosis in Acute Coronary Syndrome

Area of Science:

• Cardiology
• Immunology
• Biochemistry

Background:

• Acute coronary syndromes (ACS) are a leading cause of global mortality.
• Interventional treatments have improved outcomes, but optimizing drug therapy remains crucial.
• Inflammation's role in atherosclerosis and myocardial infarction (MI) is a significant area of research.

Purpose of the Study:

• To review current evidence on the inflammatory state at presentation and its correlation with MI prognosis.
• To identify key inflammatory pathways, therapeutic limitations, and future research directions.
• To analyze the association between inflammatory markers and post-infarction mortality and morbidity.

Main Methods:

• Review of existing scientific literature on inflammation in myocardial infarction.
• Analysis of studies investigating various inflammatory markers, including hsCRP, fibrinogen, and cytokine levels.
• Evaluation of the clinical significance and prognostic value of inflammatory markers.

Main Results:

• Both innate and acquired immune components contribute to the inflammatory cascade in MI.
• Increased levels of inflammatory cells and cytokines are observed.
• Several inflammatory markers show association with post-infarction mortality and morbidity, necessitating clinical context integration.

Conclusions:

• Inflammatory markers are associated with MI prognosis but require careful clinical interpretation.
• Selective inhibition of specific inflammatory pathways, rather than non-selective anti-inflammatory drugs, is crucial for therapeutic development.
• Further research is needed to develop effective anti-inflammatory therapies targeting specific pathways to improve patient prognosis.
