Brief Summary:
The study is being performed to determine whether probiotics (GoodBelly) improves blood vessel function.Probiotics similar to yogurt are living micro-organisms (beneficial to its host) the lives in the intestine. Patients who have coronary artery disease will be enrolled in this study. The research results will be used to determine if the type of bacteria present in the intestines play a role in the pathogenesis of cardiovascular disease. Patients with coronary artery disease will be enrolled for up to 12 weeks. Patients will take the probiotic for 6 weeks. Following the 6 week period there is a washout period of 4 weeks, and an optional antibiotic study called vancomycin. Patients will take the vancomycin for 10 days. Blood vessel function will be measured by ultrasound before and after the probiotic supplement and vancomycin antibiotic. Blood will also be taken before and after to evaluate for markers of inflammation.
Detailed Description:
We plan to recruit 20 patients, men with coronary artery disease, for this single center, interventional trial with the Probiotic-GoodBelly followed by Vancomycin. The study includes 6 total visits. Subjects who pass a phone screen will be invited to a screening visit for study eligibility (Visit 1) Informed consent will be reviewed; a unique study number will be assigned once written informed consent is obtained (no subject will be assigned more than 1 allocation number); relevant participant medical history will be recorded including currently prescribed medications; anthropometric measurements will be taken (height, weight, and waist circumference in metric units) and blood pressure will be recorded (measured in triplicate and averaged). Subjects will be allowed to take their blood pressure medication on the morning of their screening visit, but not the mornings of any of the other study visits to limit the acute influence of these medications on endothelial function. If the potential participant qualifies for the study, he will return 1 week after the screen for a study visit(Visit 2) where he will turn in his stool sample, undergo initial tests of endothelial function and receive 3 week supply of GoodBelly Probiotic. After 3 weeks he will have to return (Visit 3) for another 3 week supply of his probiotic. After a total of 6 weeks of taking the probiotic he will have to return (Visit 4) with his stool sample. He will be asked to fast for 6-8 hours prior to the visit to limit the acute dietary influences on vascular endothelial function. During Visit 4, endothelial function will determined by brachial artery reactivity testing His stool samples will be collected and blood samples will also be taken at this visit for systemic measurements inflammatory markers. If he agrees to the optional Vancomycin study. He will return after 4 weeks for (Visit 5). He will be asked to fast for 6-8 hours prior to the visit to limit the acute dietary influences on vascular endothelial function. At Visit 5, endothelial function will determined by brachial artery reactivity testing His stool samples will be collected and blood samples will also be taken at this visit for systemic measurements inflammatory markers. He will then be given a 10 day supply of vancomycin. After 10 days he will return (Visit 6) with his stool sample. At Visit 6, endothelial function will determined by brachial artery reactivity testing . His stool samples will be collected and blood samples will also be taken at this visit for systemic measurements inflammatory markers.
