[Cytokines and heart diseases. Attempt at an update]

Area of Science:

• Cardiovascular Medicine
• Immunology
• Molecular Biology

Context:

• Acute septic cardiomyopathy is closely associated with cytokine activity.
• Cytokines exert pleiotropic effects, impairing multiple inotropic pathways in the heart.
• Limited data exists on cytokine involvement in non-septic heart conditions.

Purpose:

• To summarize the current understanding of cytokine involvement in acute septic cardiomyopathy.
• To explore the emerging evidence of cytokines in various non-septic heart diseases.
• To highlight the significance of cytokines as mediators of myocardial dysfunction.

Summary:

• Cytokines are the primary mediators in acute septic cardiomyopathy, causing myocardial depression through complex actions on inotropic cascades.
• Emerging research suggests cytokine relevance in myocarditis, heart failure, cardiomyopathies, acute coronary syndromes, and post-cardiopulmonary bypass inflammation.
• Further investigation is needed to fully elucidate the role of cytokines in the pathogenesis of diverse cardiac conditions.

Impact:

• Provides a concise overview of cytokine roles in cardiac pathology.
• Highlights the need for further research into cytokine-targeted therapies for heart disease.
• Enhances understanding of the molecular mechanisms underlying myocardial dysfunction in sepsis and other inflammatory states.
