NCT03123107
Postoperative atrial fibrillation (POAF) is a common complication following cardiac surgery that increases the incidence of stroke, kidney injury and death. Vitamin C has been shown to decrease the incidence of POAF follow cardiac surgery, but the optimal dose has not been identified. With this project, the investigators plan to gather pharmacokinetic and dose-response data for vitamin C in the cardiac surgery population. The investigators plan to conduct a small interventional pilot study investigating the pharmacokinetics and pharmacodynamics of Vitamin C in patients undergoing coronary artery bypass graft (CABG) surgery. Patients enrolled will receive an intravenous dose of Vitamin C the day before surgery and the day after. Patients will have blood samples obtained with each dose for analysis of vitamin C concentrations and several biomarkers of oxidative stress. Analysis of samples will be performed within the Department of Pharmaceutical Sciences at Wilkes University.

Chronic Heart Failure (CHF) is a frequent pathology burdened with mortality and significant morbidity. Sleep apnea syndrome (SAS) is frequently associated with CHF in 20% to 75% of cases. Treatment of SAS is however inconsistently associated with a decline in the morbidity and mortality. To date, the CHF medical treatments have been reported to be inconsistently efficient in the treatment of SAS. SACUBITRIL-VALSARTAN (ENTRESTO®) is a new treatment of CHF recently indicated class I, level B in the recent European Society of Cardiology (ESC) guidelines 2016 on CHF. PARADIGM-HF trial demonstrated that morbidity and mortality can be improved with SACUBITRIL-VALSARTAN. In comparison to enalapril, it reduced the occurrence of cardiovascular death or hospitalisation for CHF by 20% with a 16% reduction in all-cause mortality. The purpose of the research is the evaluation of SACUBITRIL-VALSARTAN combination in CHF patients presenting sleep apnea syndrome. A three months real life observational trial is performed. A measure of the Apnea Hypopnea Index is realised before and after 3 months of SACUBITRIL-VALSARTAN treatment. A concomitant evaluation of cardiological and quality of life parameters is realized.
