Atherosclerotic coronary artery disease (CAD) affects more than 18 million
adults and causes over 370,000 deaths annually. CAD is the main cause of heart
attacks, which occur when atherosclerotic plaques in
the heart rupture.
Although there have been numerous advances in the detection
and treatment of CAD, current clinically available imaging approaches have
limitations, specifically in detecting unstable atherosclerotic plaques, said
Li. We know that inflammatory cells play an important role in the development
of CAD and, as such, are exploring PET radiotracers that can help detect and
characterize inflammation in atherosclerotic plaques.
With his Mars Shot Award, Li and colleagues will investigate
the PET radiotracer 64Cu-Db-CD11b to assess its ability to detect
vulnerable atherosclerotic plaques in a murine model. The researchers will also
use 64Cu-DbCD11b PET/CT to monitor response to anti-inflammatory
therapies aimed at stabilizing vulnerable plaques in mice.
This project will have significant translation value, as
noninvasive assessment of vulnerable atherosclerotic plaques is expected to
assist in identification of patients at risk and help determine when and how to
treat them, stated Li.
