The CutC, a gut microbial enzyme important for TMAO synthesis, was discovered to be linked to increased stroke severity and unfortunate outcomes.

For the first time, Cleveland Clinic researchers have discovered that the gut microbiota influences stroke severity and functional impairment after a stroke. The findings, which were published in Cell Host & Microbe, lead to new stroke treatments and prevention strategies.

The head of the Cardiovascular & Metabolic Sciences department named Dr. Hazen and his group have effectively been exploring the roles of the gut microbiome in cardiovascular health and disease, including the adverse consequences of trimethylamine N-oxide, a side-effect delivered when gut microscopic organisms digest certain supplements abundant in red meat and other animal product.

In this study, Dr. Hazen who is the head of the Cardiovascular & Metabolic Sciences department has found that dietary choline and trimethylamine N-oxide created a better size of stroke and strictness and not so good outcomes in the models of the animals. It is also observed that simply transplanting gut microorganisms capable of producing trimethylamine N-oxide was enough to significantly reduce stroke severity.

He also discovered that important trimethylamine N-oxide levels can lead to the growth of the cardiovascular disease. In clinical studies linking many patients, where they have shown that blood levels of trimethylamine N-oxide predict future risk of heart attack, stroke, and death -results that have been simulated around the world. Thus studies were the first to show a link between trimethylamine N-oxide and improved risk for thickening of the blood.  

The researchers evaluated brain injury in preclinical stroke mice with increased TMAO levels to those with lower levels. Following a stroke, those with higher levels of TMAO showed more extensive brain damage and more motor and cognitive functioning impairments. The researchers also discovered that dietary adjustments that affect TMAO levels, such as eating a lesser amount of eggs and red meat, affected the sternness of strokes.

Patients' functional abilities resulting from a stroke, which happens when blood flow to the brain is restricted, are a key issue. Therefore to understand id choline and trimethylamine N-oxide affect the function of post-stroke along with the severity of stroke where the researcher related the performance on several tasks pre-stroke, and then both in the long term and short term.
