Unraveling the thread of uncontrolled immune response in COVID-19 and STEMI: an emerging need for knowledge sharing

Area of Science:

• Immunology
• Cardiology
• Infectious Diseases

Background:

• The coronavirus disease 2019 (COVID-19) pandemic highlights the need for knowledge sharing regarding severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
• Myocardial infarction remains a leading cause of death, with immune system deregulation potentially exacerbating critical illness and organ failure.
• Shared immune responses, including neutrophilia, monocytosis, and lymphopenia, are observed in both severe COVID-19 and ST-elevation myocardial infarction.

Purpose of the Study:

• To explore the cellular and molecular mechanisms of immune response activation and downregulation in myocardial infarction and COVID-19.
• To enhance understanding of the pathophysiology linking these critical conditions.
• To identify potential innovative therapeutic strategies for reducing mortality in both infectious and non-infectious diseases.

Main Methods:

• Review of existing literature on immune cell dynamics in ST-elevation myocardial infarction and COVID-19.
• Comparative analysis of inflammatory profiles in severe cases of both conditions.
• Examination of molecular pathways governing innate and adaptive immunity.

Main Results:

• A proinflammatory imbalance, favoring innate over adaptive immunity, is associated with adverse outcomes in both conditions.
• The immune cell profiles in severe ST-elevation myocardial infarction closely resemble those reported in severe COVID-19.
• Deregulation of the immune system contributes to exaggerated inflammatory responses and multi-organ failure.

Conclusions:

• Shared immune mechanisms in myocardial infarction and COVID-19 offer therapeutic targets.
• Further research into these immune pathways could lead to novel treatments for critical illnesses.
• Knowledge sharing is crucial for developing therapies to reduce mortality across diverse medical scenarios.
