The overall goal of this PET-MR imaging trial is to evaluate 11C-Martinostat, a histone deacetylase targeted radioligand, in patients with aortic stenosis, individuals with diabetes, and healthy volunteers.
Histone deacetylases (HDACs), a class of epigenetic enzymes, play an important role in the pathophysiology of heart failure, including development of left ventricular hypertrophy and myocardial fibrosis. Preclinical data demonstrate the importance of HDAC inhibition in attenuating these pathological processes and maintaining the integrity of the myocardium. However, the role of HDACs in the human heart, and the utility of HDAC inhibition remains unknown. Therefore, a noninvasive method to detect HDAC activity in the human heart in healthy individuals and patients with heart disease may be of m…
