Detaillierte Beschreibung
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 such as reduction in endotoxemia, and enhanced production of short-chain fatty acids.
However, whether administration of probiotics also has a protective effect in subjects with metabolic syndrome (MetS), who are at high risk for developing atherosclerosis, remain unknown.

Was misst die Studie?
Primäre Ergebnismessungen
Ergebnis Maßnahme |
Maßnahmenbeschreibung |
Zeitfenster |
|---|---|---|
|
Flow-mediated slowing (FMS)
Zeitfenster: from baseline to 12 weeks after intervention
|
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

Metabolic Syndrome Severity Z Score (MetZ score)
Zeitfenster: from baseline to 12 weeks after intervention
|
MetZ score is an weighted score of the five traditional components of Metabolic syndrome (waist, triglyceride, HDL cholesterol, SBP and fasting glucose).
It's used to evaluate the severity of metabolic disorder, and a higher score indicates a more severe status.
|
from baseline to 12 weeks after intervention
