Brief Summary

Atherosclerosis is a major risk factor for cardiovascular diseases. Recently, dysbiosis of gut microbiota has been reported to play an important role in the pathogenesis of atherosclerosis. Animal studies have demonstrated that administration of probiotics help delay the progression of atherosclerosis through several mechanisms. This trial aims to examine its protective effect in humans.

Outcome Measures

Primary Outcomes (1)

  • Flow-mediated slowing (FMS)

    FMS is a simple test for endothelial functions measured by Vicorder. In patients whose endothelial function or flow-mediated vasodilation are compromised, the FMS is substantially reduced.

    from baseline to 12 weeks after intervention

Secondary Outcomes (6)

  • gut microbiota

    from baseline to 12 weeks after intervention

  • microbial metabolites

    from baseline to 12 weeks after intervention

  • Metabolic Syndrome Severity Z Score (MetZ score)

    from baseline to 12 weeks after intervention

  • Lipid profiles

    from baseline to 12 weeks after intervention

  • Blood pressure

    from baseline to 12 weeks after intervention

  • +1 more secondary outcomes
