The purpose of this study is to see if ascorbic acid (Vitamin-C) therapy will reduce
inflammation following heart surgery.
Official title: The Impact of Ascorbic Acid Therapy on Inflammatory Mediators in Cardiothoracic Surgery Patients: The Atrial Fibrillation Suppression Trial IV (AFIST IV) Pilot Study
Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Prevention
Primary outcome: In CTS patients receiving standard of care therapy,evaluate the effect of ascorbic acid therapy on c-reactive protein (CRP) concentration on post-CTS day 3 and the total post-CTS systemic exposure to CRP over 4 days.
Secondary outcome: Evaluate the effect of high intensity versus low intensity statin therapy on blood concentrations of fibrinogen, and White blood cell count on post-CTS days 3 and the total post-CTS systemic exposure to these biomarkers over 4 days.
Atrial Fibrillation is a significant cause of morbidity following cardiothoracic surgery.
Despite prophylactic therapy with beta-blockers and amiodarone, post-operative atrial
fibrillation occurs in approximately 22% of patients. We believe that by reducing the
inflammation that is caused during CTS, we can see further improvements without any negative
effects on hemodynamics. Ascorbic acid, a free radical scavenger has been found to lower
inflammation mediators but never in a CTS population. This study will help determine the
affect of ascorbic acid on the inflammation associated with CTS.
