11C-acetate/18Fluorodeoxyglucose-FDG PET/CT and Cardiac MRI in Pulmonary Hypertension
Pulmonary Hypertension
About this trial
This is an interventional diagnostic trial for Pulmonary Hypertension focused on measuring pulmonary hypertension, right ventricular function, 11C acetate, FDG, ranolazine
Eligibility Criteria
Inclusion Criteria:
Participation in the companion treatment protocol "A randomized, double-blind, placebo controlled, multi-center study to assess the effect of ranolazine on outcomes in subjects with pulmonary hypertension and right ventricular dysfunction accompanied by a comparative study of cellular metabolism in subjects with pulmonary hypertension with and without right ventricular dysfunction"
Exclusion Criteria:
- Pregnancy or lactation: Women of childbearing potential must have a negative urine or blood pregnancy test on the day of the PET/CT scan.
- Severe anxiety or claustrophobia prohibiting completion of imaging
- Inability to tolerate imaging procedures (1 hour MRI, 30 min and 15 min PET)
- Implantable cardioverter-defibrillator, Pacemaker, hazardous metallic implants or any other contraindication to MRI.
- Uncontrolled diabetes mellitus with fasting glucose > 150 mg/dL
Sites / Locations
- University of Pennsylvania
Arms of the Study
Arm 1
Experimental
11c-acetate and 18F-FDG, and cardiac MRI
For each PET/CT imaging session subjects will receive a 15-25 millicurie intravenous injection of 11C-acetate and a 10 millicurie injection of 18F-FDG At baseline/6 months follow up, a cardiac MRI will be performed.
