Fat Around Heart Arteries as a Measure of Inflammation in Patients With Diabetes

In this prospective study, the objective is to investigate inflammation in the arteries of the heart. A heart CT scan (CCTA) will be used to measure inflammation by assessing the fat tissue surrounding the arteries of the heart. Participants with type 2 diabetes who have no heart symptoms have been examined, using a CCTA at the start of the study and again after 12 months. This study aims to answer the following questions: * Can inflammation in the surrounding fat tissue at the baseline CCTA predict the amount and type of plaque, and the presence of harmful plaque characteristics present after 12 months? (paper 1) * Do changes in inflammation in the surrounding fat tissue from baseline to the 12 months CCTA correlate with the amount and type of plaque and the presence of harmful plaque characteristics at the 12 months CCTA? (paper 1) * Is inflammation in the surrounding fat tissue a predictor for the development of cardiovascular events after a follow-up period of 7 years? (paper 2) * Do changes in inflammation in the surrounding fat tissue after 12 months predict the later development of cardiovascular events after a follow-up period of 7 years? (paper 2)
