Condition(s) targeted: Coronary Artery Disease
Intervention: Creatine (Dietary Supplement); L-arginine and creatine (Dietary Supplement); l-arginine (Dietary Supplement); placebo, double (Dietary Supplement)
Sponsored by: Boston University

The study is a double blind 2x2 factorial study. Patients with coronary disease will be
randomly be assigned to L-arginine (9 g/day), creatine 21 g/d, both, or neither dietary
supplement. The function of the endothelium will be tested using ultrasound before and after
each treatment. These studies will help us understand why the endothelium is abnormal in
patients with coronary artery disease and how L-arginine is acting on endothelial function.
