The web of intrigue: unraveling the role of NETosis within the gut-microbiome-immune-heart axis in acute myocardial infarction and heart failure.

This review summarizes the role of NETosis, or the release of neutrophil extracellular traps (NETs), and its interplay with the gut microbiome in acute myocardial infarction (AMI) and heart failure. NETosis contributes to inflammation, thrombosis, and atherothrombosis, all central to the pathophysiology of AMI and heart failure. NETosis can be activated by inflammation and dietary factors, indicating association with metabolic conditions. In cases of heart failure, NETosis is regulated by inflammatory molecules such as C-reactive protein (CRP), and Krüppel-like factor 2 (KLF2) - a protein that plays a role in controlling inflammation, and angiotensin II. Changes in the gut microbiome are linked to the severity and recovery of cardiac injury post-AMI and heart failure progression. The microbiome's influence extends to immune modulation and inflammatory responses, potentially affecting NETosis.
