Sponsor's own description

The main aim of this project is to demonstrate an association between gut and oral microbiota and their metabolites to carotid atherosclerosis and risk of ischemic stroke. The investigators aim to show that these metabolite levels are diet-dependent (mainly egg yalk and red meat) and associated with specific types of microbiota. The investigators to assess serum microbiota metabolite levels as a predictor of stroke and plaque progression for patients with carotid atherosclerosis.
