• History of stroke within 30 days prior to enrollment/consent
• Chronic kidney disease (CKD) of stage 4 or greater based on an Estimated Glomerular Filtration Rate (eGFR) <30ml/Min, unless the subject is on chronic renal replacement therapy
• Hemoglobin levels <10g/dL verified by a lab test no older than 14 days prior to enrollment, unless the subject has a history of chronic anemia at a stable level, no recent bleeding diathesis or history of blood transfusion in the last six weeks
• Pregnant or nursing, for females of child-bearing potential (< 50 years of age)
• Participating in another interventional research study that may interfere with study endpoints
