Cardiac Perfusion and Metabolism With [11C] Acetate PET/CT is Associated With Hematopoietic System Activation in Acute Decompensated Heart Failure: An Imaging Sub-study
The purpose of this sub-study is to use positron emission tomography and computed tomography imaging (PET/CT) with an investigational drug called [11C] acetate to see if inflammation in patients with acute decompensated heart failure (ADHF) can cause changes in blood flow and oxygen use in the heart. This study may help physicians better understand how to treat patients diagnosed with ADHF in the future.
At least 18 years of age. Enrollment in the UAB CMC-ADHF study under the separate UAB approved research protocol (IRB-300000114, PI Rajapreyar) Negative urine or serum β-hCG test within 48 hours of [11C] acetate administration in women of child bearing potential. Women who are post-menopausal with at least 1 year since last menses or documented surgical sterilization will not require pregnancy testing.
Exclusion Criteria:
Inability to provide informed consent Pregnancy Inability to lie still for the imaging study Weight exceeding the weight limit of the PET imaging table (500 pounds).
