Diabetes Patients' heart arteries under the scanner: new study tracks silent changes
NCT ID NCT05801432
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows over 500 adults with type 2 diabetes who had a heart CT scan years ago. Researchers will repeat the scan to see how plaque builds up in heart arteries over time and identify factors that increase risk. The goal is to better understand heart disease in diabetes, not to test a new treatment.
