Warfarin Versus Aspirin in Reduced Cardiac Ejection Fraction (WARCEF) Trial

Summary

The purpose of this study is to determine which of two treatments, Warfarin or aspirin, is better for preventing death and stroke in patients with poor heart function. We are now transitioning into the sub-analysis part of the WARCEF patient data. The study has recently completed data analysis for its Primary Aim. All randomized patients have completed their follow up. All study related procedure as per the protocol has been completed. We are now in the extension phase of the study to obtain more patient data to address further aims of the study. No new procedures are performed and data already in place at the sites will be collected (EKG and echocardiograms). The aims for this study extension are: * To assess progression of cardiac dysfunction over time among heart failure patients * To correlate prognosis with cardiac dysfunction
