Condition(s) targeted: Cardiac Surgery; Inflammation

Intervention: Ascorbic acid (Drug); Placebo (Drug)

Phase: Phase 4

Status: Completed

Sponsored by: Hartford Hospital

Official(s) and/or principal investigator(s):

The purpose of this study is to see if ascorbic acid (Vitamin-C) therapy will reduce inflammation following heart surgery.

Clinical Details

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.

Detailed description: 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.
