Key result
Gut microbiome alterations are linked to thrombosis, showing stronger evidence for arterial than venous events.
Why the study?
Although evidence supports a link between the gut microbiome and thrombosis, mechanisms remain clearer for arterial than venous thrombosis and require further clarification.
The gut microbiome is emerging as a potential modulator of thrombotic disease, highlighting a novel interorgan pathway that requires further mechanistic and clinical validation.

Does not support microbiome-targeted interventions in thrombosis care; hypothesis-generating for arterial events with mechanistic validation required.
Gut microbiome has emerged as an important modulator of thrombotic disease through complex immunometabolic and interorgan pathways. Microbiome-derived metabolites have been associated with platelet activation, endothelial injury, and adverse cardiovascular outcomes. However, evidence remains stronger for arterial than for venous thrombosis, although accumulating data suggest that dysbiosis may represent an important yet underrecognized contributor to the pathogenesis of venous thromboembolism. While current evidence supports a biologically plausible association between the gut microbiome and thrombosis, further studies are needed to clarify the underlying mechanisms and determine their clinical significance.

Tsante et al. (2026) conducted a review in Thrombotic disease. Gut microbiome dysbiosis was evaluated. Current evidence supports a biologically plausible association between the gut microbiome and thrombosis, though evidence remains stronger for arterial than for venous thrombosis.
