Evaluate Use of Mangosteen Juice Added to Usual Care in Reducing Risk of

Status Terminated

Clinical Trial Summary

This study is being done to see if the addition of mangosteen juice to standard medical care will reduce the risk of atrial fibrillation (AF) recurrence following direct current (DC) cardioversion. The study will also look at the effects the mangosteen juice may have on biomarkers of inflammation and endothelial cell dysfunction (the tissue lining the arteries does not function properly).

Clinical Trial Description

Mangosteen Effects on Inflammatory Markers in Atrial Fibrillation Trial is a study designed to test the primary hypothesis that a dietary supplement (Mangosteen) containing anti-inflammatory and anti-oxidant properties may effect the measured levels of inflammatory biomarkers. Secondarily, this study will compare the attenuation of markers of endothelial cell dysfunction including endothelial progenitor cells (EPCs), clinical levels of anticoagulation (INR), digoxin, lipids, and glycosylated hemoglobin (Hgb A1c), quality of life measurements, AF recurrences, and associated levels of inflammatory markers with those experiencing recurrent AF between the mangosteen group and the placebo group.

This trial will randomize 250 patients presenting to the Mayo Clinic Cardioversion Unit over one year to two groups including a mangosteen supplemented group versus a control group with placebo juice. Patients will be enrolled who have a history of paroxysmal, persistent, or longstanding persistent atrial fibrillation and excluded if they have a history of recent surgery, myocardial infarction, infection, collagen vascular disease with active inflammation, or thyroid disease. Furthermore, patients already on corticosteroids will be excluded. Patients will be evaluated at enrollment and followed at 3 months and 6 months with repeat ECG, laboratory testing of inflammatory biomarkers and endothelial function, as well as quality of life questions.

The trial will track the effect of natural juices containing anti-inflammatory and anti-oxidant properties on inflammatory markers, endothelial progenitor cells, and quality of life. This trial will attempt to determine if any dietary supplement effects to inflammatory markers correlate with the rate of recurrent AF in each of the two groups. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
