Improvement Assessment of Coronary Flow Dysfunction Using Fundamental Fluid Dynamics

"Patients would under go a Cardiac rest and stress PET scan and include the following drug administration:~1. N-13 Ammonia radionuclide - Two doses, 10 mCi for rest, 20 mCi for stress~2. Lexiscan - stress agent for PET scan~Patients would also undergo Coronary catheterization including the following drug administration and device usage:~1. Combowire to obtain pressure and flow readings on Combomap machine (Volcano Therapeutics, CA).~2. Adenosine - stress agent during catheterization, 140 ug/Kg/min"
