Clinical Trial Summary

This study evaluates the efficacy of high-dose fish oil in decreasing rates of gastrointestinal bleeding in patients with continuous-flow left ventricular assist devices. Half of the patients without history of bleeding will receive fish oil while the other half will not. Half of the patients with history of bleeding will receive fish oil while the other half will not. Markers of angiogenesis and inflammation, as well as changes in the microbiome will be assessed in each group.


Clinical Trial Description

A potential mechanism of bleeding in patients with continuous-flow left ventricular assist devices (CF-LVAD) is dysfunctional angiogenesis. Angiogenesis is a complicated process controlled by several markers. Previous studies have shown that elevated Angiopoietin-2 and TNF-alpha are associated with bleeding events in CF-LVAD patients. Fish oil has anti-inflammatory and potentially anti-angiogenic properties. A retrospective study of CF-LVAD patients on high-dose fish oil showed a marked decrease in gastrointestinal bleeding rates in these patients. Additionally, these patients had lower levels of circulating Angiopoietin-2. Fish oil is known to have an effect on the microbiome, and the aforementioned effects may be seen in changes of the microbiota. ;
