The prevalence of asymptomatic CAD in T2D is unclear. We investigated the CAD burden using the gold standard IVUS in an asymptomatic T2D-cohort compared to a reference population without T2D. Patients with T2D and ≥ 1 cardiovascular (CV) risk factor (n=56, 21% women, mean age/diabetes duration 65.2±7.8/13.1±5.8 years, HbA1c 7.2±1.1%, systolic BP 136±17 mmHg, LDL-cholesterol 2.3±0.8 mmol/L) underwent invasive coronary angiography with IVUS. Reference population comprised heart transplant donors free from T2D and CAD who had IVUS performed 7-11 weeks post-transplant (n=76). IVUS was described by maximal intimal thickness (MIT), percent atheroma volume (PAV) and normalized total atheroma volume (TAV). All indices of atherosclerosis were significantly increased in T2D (T2D cohort: MIT 0.75±0.27 mm, PAV 33.7±9.8%, TAV 277.0±137.2 mm 3 vs. reference population: MIT 0.44±0.18 mm, PAV 20.1±7.4%, TAV 139.0±110.0 mm 3 , [p-values Disclosure A.P.
