5. Study Description

Brief Summary
Researchers are studying the effect of a single dose of oral myeloperoxidase on heart failure versus placebo.
Detailed Description
Enroll subjects with a normal ejection fraction referred to the catheterization laboratory for evaluation of breathlessness or shortness of breath. Perform safety lab sampling, echocardiography, arterial tonometry for pulse wave analysis, and assessment of endothelial function prior to administration of study drug. During the catheterization researchers will perform blood draws, assess baseline exercise capacity at rest and during exercise. Researchers will also do an echocardiogram to take measurements of the heart. Subjects will be randomized to one of two groups, Oral Myeloperoxidase Inhibitor or placebo group. Study drug or placebo will be administered followed by a repeat of the baseline catheterization assessments. At the conclusion of the second exercise test the subject will be moved to a room and monitored overnight for safety. Repeat blood draws, echocardiogram, endothelial function test, and heart monitoring will be completed. The subject will be asked to follow up with the researchers between 9-14 days after the study drug dosage. The subjects history and blood work will be completed at that visit.
