Have you had a heart attack, and do you want to help improve strategies for blood transfusion? The study is comparing two strategies for blood transfusions in heart attack patients who have anemia—whether to give a blood transfusion when the hemoglobin level is less than 10 g/dL, or to give blood only when the blood count is below 8 g/dL. To participate in this study, you must be at least 18 years old, have anemia, and be hospitalized for a heart attack. The study is located in New Brunswick, New Jersey.

Do you have coronary heart disease, and are you interested in helping researchers improve how they treat and prevent this condition? This study is exploring new risk factors that may allow for more people with heart disease to get approved for an implantable cardioverter defibrillator (ICD), a device that can detect and stop irregular heartbeats. To participate in this study, you must be 18 years old or older and already have or be eligible for an ICD. This study takes place in Buffalo, New York.
