Brief Summary
One in every two deaths in the United States is caused by cardiovascular disease. Despite strong mechanistic links established between a diet rich in lipids and the pathogenesis of cardiovascular disease, therapeutic advances have focused on reduction in either ingestion or synthesis of cholesterol, and reduction in dietary trans and saturated fatty acids and triglycerides. Even in the setting of aggressive high potency statin therapy and global cardiovascular risk reduction efforts, most clinical trials reveal a significant residual cardiovascular risk with, at best, only 30% reduction in major adverse cardiovascular events. There exists a significant unmet clinical need for identifying novel therapies for the prevention and treatment of cardiovascular disease. This requires identification of additional contributory processes to cardiovascular disease pathogenesis, so that mechanism-based interventions may be developed. Endothelial dysfunction is a pathological state in which there is systemic inflammation of vascular endothelium with consequent expression of pro-vasoconstrictive mediators, thrombotic and atherogenic tendencies. Endothelial dysfunction precedes the development of atherosclerosis and portends an increased risk of future adverse cardiovascular events. Endothelial dysfunction, therefore, can serve as a "barometer" of future cardiovascular risk. Measurement of Flow-mediated dilation ( FMD) is widely accepted as a method to assess vascular endothelial function.

Outcome Measures
Primary Outcomes (1)
change in baseline flow mediated dilation (FMD) after probiotic consumption
This is a measurement of endothelial function in the brachial artery
from baseline to 24 hours after consumption and approximately 7 days after consumption
Secondary Outcomes (3)
Interleukin-6
from baseline to 24 hours after consumption and approximately 7 days after consumption
Interleukin-8
from baseline to 24 hours after consumption and approximately 7 days after consumption
Interleukin-12
from baseline to 24 hours after consumption and approximately 7 days after consumption
Study Arms (2)
GoodBelly Probiotic
EXPERIMENTALSubjects randomized to this arm consume one serving of the Goodbelly lactobacillus plantarum 299v probiotic
Placebo
PLACEBO COMPARATORSubjects randomized to this arm consume one serving of the Goodbelly that does not contain lactobacillus plantarum 299v
Interventions
Consumption of 1 serving of Goodbelly probiotic daily for 6 weeks. This will be followed by an observation period for 6 weeks during which the subjects will not consume Goodbelly.
To prepare the placebo, the dietitian will first heat a water bath to 80 degrees Celsius. This removes the lactobacillus plantarum 299v from the probiotic drink

- LV dysfunction as defined by an LV ejection fraction documented as \< 45% within 1 year of enrollment by an echocardiogram, MRI, or nuclear imaging.
- Uncontrolled hypertension with blood pressure greater than 170/100 mmHg at the screening visit.
- Known history of chronic renal insufficiency, liver dysfunction, or cancer besides non-melanoma skin carcinomas or localized prostate cancer requiring systemic treatment within five years of enrollment.
- Known history of cognitive impairment or inability to follow study procedures
- Patient with an implanted defibrillator or permanent pacemaker on which the potential participant is known to rely upon for greater than 50% of ventricular depolarizations.

- Pregnancy
- Patients who are currently taking Vitamin K antagonists such as coumadin, warfarin.
- Those who are daily drinkers.
- Patients with gastrointestinal diseases that might alter the impact of a probiotic (e.g. status post colectomy, short gut syndrome, or inflammatory bowel disease)
